As researchers now demonstrate based on a computer simulation, not only do variations in insulation play a key role, but also the mutual influence of glaciated continents and climate.
Ice ages and warm periods have alternated fairly regularly in Earth's history every sense the earth was created : Earth's climate cools roughly every 100,000 years, with vast areas of the northern hemisphere of the Earth such as North America, Europe and Asia being buried under thick ice sheets.- Ice sheets form in areas where snow that falls in winter does not melt entirely over the summer. Over 100,000 thousands of years, the layers of snow pile up into thick masses of ice, growing thicker and denser as the weight of new snow and ice layers compresses the older layers. Eventually, the pendulum swings back it gets warmer and the ice masses melt. While geologists and climate physicists found solid evidence of this 100,000-year cycle in glacial moraines, marine sediments and arctic ice, until now they were unable to find a plausible explanation for it. ----- In the natural cycle of the Earth, the Earth can warm and cool, without any human interference.--For the past millions years this has occurred over and over again at approximately 100,000 year intervals. About 80-90,000 years of ice age with about 10-20,000 years of warm period, give or take some thousands of years. But in these last hundred years the human interference have changed all of that, Now the Earth has been and is warming too fast, quickly and the glacier are melting to fast! -------
These Nature cycles of cooling and warming increase and decrease the amount of solar forcing imposed within our climate system and that actually causes the temperature to rise and fall with calculable regularity. The more time the earth or land mass spends closer to the sun (at perihelion), the more energy it receives thus warming. The more time it spends farther from the sun (at aphelion) the less energy it receives and the earth cools.
The 'eccentricity' cycle period is around 100,000 years. This causes the orbit of the earth to elongate or become more elliptical.-- Jupiter and Saturn periodically elongate Earth’s orbit, and this effect combines from time to time with slow changes in the direction and degree of Earth’s tilt that are caused by the gravity of our large moon. ------Imagine that the more elliptic it becomes, the less time during the year it spends near the sun. So the planet receives less solar energy and cools a bit.
The 'obliquity' cycle tilts the earth every 41,000 years and that causes the land mass of the norther hemisphere to face more towards the sun or less towards the sun This is the cycle and system that ALLAH created for this Earth!
The 'precession'
-cycle occurs about every 26,000 years and influences the wobble of the polar axis.(In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In particular, it can refer to the gradual shift in the orientation of Earth's axis of rotation, which, similar to a wobbling top, traces out a pair of cones joined at their apices in a cycle of approximately 26,000 years.[1] The term "precession" typically refers only to this largest part of the motion; other changes in the alignment of Earth's axis—nutation and polar motion—are much smaller in magnitude.-Earth's precession was historically called the precession of the equinoxes, because the equinoxes moved westward along the ecliptic relative to the fixed stars, opposite to the yearly motion of the Sun along the ecliptic.(ecliptic-a great circle on the celestial sphere representing the sun's apparent path during the year, so called because lunar and solar eclipses can occur only when the moon crosses it.)(equinoxes-the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length (about September 22 and March 20). This term is still used in non-technical discussions, that is, when detailed mathematics are absent. Historically ) This also influences earths climate by causing winters and summers to be warmer or colder depending on the amount of land surface being more or less exposed to the sun and all this is still apart of the system that ALLAH created for this Earth ..
These are three main influences considered in that regulate the general amount of energy received in our earth climate system. As we warm and cool, more or less of our natural greenhouse gases are released into the atmosphere, or stored in the oceans, ice and earth.
--Climate on Earth has changed on all time scales, including long before human activity could have played a major role in the rapids change of global warming. Great prog-ress has been made in understanding the causes and mechanisms of these nature systems of climate changes. From a scientific point of view Changes in Earth’s radiation balance were the principal driver of past climate changes, but the causes of such changes are varied in the nature system of the Earth . For each case – be it the Ice Ages, the warmth at the time of the dinosaurs or the fluctuations of the past millennium – the specific causes must be established individually, this is the scientific point of view, But the real point of view is that this is the system of ALLAH for this Earth! .
Global climate is determined by the radiation balance of the planet .There are 3 fundamental ways the Earth’s radiation balance can change, thereby causing a climate change: And also there is a forth (1) changing the incoming solar radiation (e.g., by changes in the Earth’s orbit or in the Sun itself), (2) changing the fraction of solar radiation that is reflected (this fraction is called the albedo – it can be changed, for example, by changes in cloud cover, small particles called aerosols or land cover), and (3) altering the long- wave energy radiated back to space (e.g., by changes in green-house gas concentrations). In addition, local climate also depends on how heat is distributed by winds and ocean currents. All of these factors have played a major role in the past nature system of climate changing.(4) And the forth is the damage to the ozone layer, Which has had an Effects on the Environment, An Effects on Human Health, An Effects on Plants life, An Effects on Marine Ecosystems, And Effects on Biogeochemical Cycles, And Effects on Materials,----
-----We have to remember that science was created so man could study the creation! Science is the method that is used to study creation ---
Starting with the ice ages that have come and gone in regular cycles for the past nearly three million years, there is strong evidence that these are linked to regular variations in the Earth’s orbit around the Sun, the so-called Milankovitch cycles ( Jupiter and Saturn gravitational pull on the solar system ). These cycles change the amount of solar radiation received at each latitude in each season (but hardly affect the global annual mean), and they can be calculated with astronomical precision. There is still some discussion about how exactly this starts and ends ice ages,But only ALLAH knows!, And many studies suggest that the amount of sum-mer sunshine on northern continents is crucial: if it drops below a critical value, snow from the past winter does not melt away in summer and an ice sheet starts to grow as more and more snow accumulates. Climate model simulations confirm that an Ice Age can indeed be started in this way, while simple conceptual models have been used to successfully ‘hindcast’ the onset of past glacia-tions based on the orbital changes. The next large reduction in northern summer insolation, similar to those that started past Ice Ages, is due to begin in 30,000 years.
Although it is not their primary cause, atmospheric carbon di-oxide (CO2) also plays an important role in the ice ages. Antarctic ice core data show that CO2 concentration is low in the cold gla-cial times (~190 ppm), and high in the warm interglacials (~280 ppm); atmospheric CO2 follows temperature changes in Antarctica with a lag of some hundreds of years. Because the climate changes at the beginning and end ofice ages take several thousand years-
most of these changes are affected by a positive CO2 feedback; that is, a small initial cooling due to the Milankovitch cycles is subsequently amplified as the CO2 concentration falls. Model sim-ulations of iceage climate yield realistic results only if the role of CO2 is accounted for.
During the last ice age, over 20 abrupt and dramatic climate shifts occurred that are particularly prominent in records around the northern Atlantic These differ from the gla-cial-interglacial cycles in that they probably do not involve large changes in global mean temperature: changes are not synchro-nous in Greenland and Antarctica, and they are in the opposite direction in the South and North Atlantic. This means that a major change in global radiation balance would not have been needed to cause these shifts; a redistribution of heat within the climate system would have sufficed. There is indeed strong evidence that changes in ocean circulation and heat transport can explain many features of these abrupt events; sediment data and model simula-tions show that some of these changes could have been triggered by instabilities in the ice sheets surrounding the Atlantic at the time, and the associated freshwater release into the ocean.
Much warmer times have also occurred in climate history----but never like what we are experiencing now! When the Earth was first created it was probably completely free of ice sheets for millions of years (geologists can tell from the marks ice leaves on rock), unlike today, when Greenland and Antarc-tica wereice-covered. If the entire 2,850,000 cubic kilometres (684,000 cu mi) of ice were to melt as it is doing, it would lead to a global sea level rise of 7.2 m (24 ft).
It was once thought (and that was only six years ago) that the glaciers would be self-sustaining even in a warming world because of size and so on.
We now know that not only are the edges melting fast, but the surface melt is seeping through the ice to lubricate the junction between the glacier and the rock underneath. This is the unexpected factor that has turned scientific attention onto this escalating problem. ---
It appears that the Greenland ice is shot through with crevices, tunnels and faults through which the melting upper surface can penetrate right through the glacier, and threaten to break the attachment between the ice and the rock base.
When this happens much of this mountain of water will flow into the sea. Already twenty-one of the great glacial masses are moving seawards eight times faster than ten years ago and disintegrating three times faster than in the preceding five years.
It would seem we are on the verge of a major tipping point in climate change, if we have not already reached it. The latest US Navy survey suggests there will be no sea ice left in the Arctic summer by 2025. This has been unprecedented within the entire record of human species.-
The Greenland, Alaskan and West Antarctic ice sheets together hold about 25% of the fresh water on the planet. The effects of the collapse of either ice sheet would be huge. Once you lost one of these ice sheets, there's no putting it back for thousands of years, if ever.
If they disintegrate, sea level could rise nearly 20 meters, possibly in only one decade. This would swamp most cities and ports, as well a much of the best agricultural land. Where now 6 billion people?
----The Greenland Ice Sheet is sometimes referred to under the term inland ice, or its Danish equivalent, indlandsis. It is also sometimes referred to as an ice cap.----Melt extent in Greenland was above average in 2016, ranking tenth highest (tied with 2004) in the 38-year satellite record. Melt area in 2016 was slightly greater than in 2015, which ranked twelfth. However, near-average to below-average coastal snowfall levels that exposed bare ice earlier in the melting season, combined with warm and sunny conditions at lower elevations, led to high overall ice loss from runoff. -Data on greenhouse gas abundances going back beyond a million years, that is, beyond the reach of antarc-tic ice cores, are still rather uncertain, but analysis of geological--------------------------------------------------samples suggests that the warm ice-free periods coincide with high atmospheric CO2 levels. On million-year time scales, CO2 levels change due to tectonic activity, which affects the rates of CO2 exchange of ocean and atmosphere with the solid Earth. See Box 6.1 for more about these ancient climates.
Another likely cause of past climatic changes is variations in the energy output of the Sun. Measurements over recent decades show that the solar output varies slightly (by close to 0.1%) in an 11-year cycle. Sunspot observations (going back to the 17th cen-tury), as well as data from isotopes generated by cosmic radiation, provide evidence for longer-term changes in solar activity. Data correlation and model simulations indicate that solar variability and volcanic activity are likely to be leading reasons for climate variations during the past millennium, before the start of the in-dustrial era.
These examples illustrate that different climate changes in the past had different causes.( ) The fact that natural factors caused climate changes in the past does not mean that the current cli-mate change is natural. By analogy, the fact that forest fires have long been caused naturally by lightning strikes does not mean that fires cannot also be caused by a careless camper. FAQ 2.1 addresses the question of how human influences compare with natural ones in their contributions to recent climate change.-----------------------Human activity–now primarily fossil fuel combustion– has increased carbon dioxide concentrations from °280 to 355 mL/L since 1800; the increase is unique, at least in the past 160 000 yr, and several lines of evidence demonstrate unequivocally that it is human—caused. On This Earth, human activities are changing the natural greenhouse,
Burning of fossil fuels causes an excessive build up of carbon dioxide (Greenhouse gases) in the atmosphere increasing global warming."Greenhouse gases effect" warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."Gases that contribute to the greenhouse effect include:Water vapor:Carbon dioxide (CO). :Methane.:Nitrous oxide:Chlorofluorocarbons (CFCs).: ----------------------Human activities has jeopardize Earth’s natural systems,cycles and health of future generations

Would YOUR house be underwater? Terrifying map reveals the devastation that would be wrought if all the world's ice melted
The Earth contains around five million cubic miles of ice and 80 per cent of this is in East Antarctica icesheet alone
Scientists believe it would take more than 5,000 years for all the Earth’s ice to melt under natural circumstances
Earth hasn't been ice-free since the Eocene epoch - a period of increased temperatures 34 million years ago
If this was repeated, sea levels could rise by 216 feet changing shorelines and engulfing entire cities worldwide
National Geographic has created a series of maps showing what continents would look like if the Earth’sice continue to melted
Ice sheets surrounding the North and South poles make up 10 per cent of our entire planet’s surface, and it’s thought Earth contains five million cubic miles of frozen water - so what would happen if it all melted? National Geographic has created a series of interactive maps demonstrating the catastrophic effect Earth’s ice could cause if it melted and flowed into the oceans and seas. This could cause sea levels to rise by 216 feet, devouring cities and even countries all the while drastically altering how continents and coastlines look, and wiping out entire populations. ------- Terrifying map reveals the devastation that would be wrought if all the world's ice melted --------------------
The last time the Earth was ice-free was 34 million years ago during the Eocene epoch. If this happened again with this global warming , the entire Atlantic seaboard as we know it, in the U.S and around the world would vanish, wiping out Florida and the Gulf Coast. While the hills in San Francisco would become islands and San Diego would be lost forever
The ice sheets in Greenland and west Antarctica shrank significantly during the epoch and if Only ALLAH knows the full truth of this matter were to rise in a similar manner again as they are doing, the ice sheets across the regions could disappear into the sea completely by 2070.
If these sheets melted, it would create a knock-on effect for the rest of the world.
In Europe, for example, cities including London and Venice would be lost underwater, as would the whole of the Netherlands and most of Denmark. It would also cause the Mediterranean to expand and swell the Black and Caspian Seas.
The EPA claims that overall ice reduction depends on several factors, including the rate at which levels of greenhouse gases rise and how global temperatures react to this increase in gas.- During the 2014 - 2015 winter there was less ice in the Arctic than during any winter since measurements were made by satellite (Hackman, 2015). This finding reinforces the prediction that the Arctic will be completely free of iceduring summers by about 2040. As the Earth warms the ice starts melting sooner and is melting faster. A consequence of this is the zooplankton now contains a lot less fat. This affects the fish that feed upon the zooplankton, the seals that feed upon the fish, and then the polar bears that feed upon the seals. The whole food chain is being disturbed by a warming Earth. Humans will also be badly affected by the many changes that will take place in the Arctic and elsewhere. ------------The largest concentrations of ice on Earth are found in Greenland and Antarctica, pictured. Warming oceans are already melting the floatingice sheet in west Antarctica and since 1992, National Geographic reports the sheet loses around 65 million metric tonnes each year. If they melted it could cause the sea levels to rise globally by 216 feet
This rise in greenhouse gases is caused by humans, as National Geographic explained: ‘If we burn all the Earth’s supply of coal, oil, and gas, adding some five trillion more tonnes of carbon to the atmosphere, we’ll create a very hot planet with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58. Large swaths of it might become too hot for humans.’
This would make the Earth ice-free for the first time in 34 million years.
If this happened, the entire Atlantic seaboard would vanish, and would be lost forever.
In the east, China and Bangladesh would both be completely flooded, wiping out around 760 million people based on current population levels. The coastlines of India would also be reduced.
Whereas in South America, the Amazon Basin and the Paraguay River Basin would both become Atlantic inlets and this would wipe out Buenos Aires, coastal Uruguay, and some of Paraguay. ----------
The only areas that would survive are mountainous stretches along the Caribbean coast and in Central America.
The other continents would escape a little more lightly, but would still be affected.
In Africa, for example, Egypt, Alexandria and Cairo would be flooded but the continent wouldn’t lose as much of its land to the rising seas. National Geographic claims the Earth’s rising heat ‘might make much of it inhabitable’ though. Only ALLAH knows the full truth of this matter!
Australia would gain a new inland sea but it ‘would lose much of the narrow coastal strip where four out of five Australians now live. --------------------------------------------------------------------------------------------------------------------------------------------------------------------
Burning of fossil fuels causes an excessive build up of carbon dioxide (Greenhouse gases) in the atmosphere increasing global warming.------------The Greenhouse gases in the atmosphere trap some of the heat,---- "Greenhouse gases effect"warming that results when the atmosphere traps heat radiating from Earth toward space. -------------------------------- global warming causes and effects--- Human activity–now primarily fossil fuel combustion– has increased carbon dioxide concentrations from °280 to 355 mL/L since 1800; the increase is unique, at least in the past 160 000 yr, and several lines of evidence demonstrate unequivocally that it is human—caused. This increase is likely to have climatic consequences–and certainly it has direct effects on biota in all Earth's terrestrial ecosystems. The global nitrogen cycle has been altered by human activity to such an extent that more nitrogen is fixed annually by humanity (primarily for nitrogen fertilizer, also by legume crops and as a by product of fossil fuel combustion) than by all natural pathways combined. This added nitrogen alters the chemistry of the atmosphere and of aquatic ecosystems, contributes to eutrophiction of the biosphere, and has substantial regional effects on biological diversity in the most affected areas. Finally, human land use/land cover change has transformed one—their to one—half of Earth's ice—free surface. This in and of itself probably represents the most important component of global change now and will for some decades to come; it has profound effects on biological diversity on land and on ecosystems downwind and downstream of affected areas. Overall, any clear dichotomy between pristine ecosystems and human—altered areas that may have existed in the past has vanished, and ecological research should account for this reality. These three and other equally certain components of global environmental change are the primary causes of anticipated changes in climate, and of ongoing losses of biological diversity. They are caused in turn by the extraordinary growth in size and resource use of the human population. On a broad scale, there is little uncertainty about any of these components of change or their causes. However, much of the public believes the causes–even the existence–of global change to be uncertain and contentious topics. By speaking out effectively, we can help to shift the focus of public discussion towards what can and should be done about global environmental change. -------------------- many
greenhouse gases, including carbon dioxide, stay in the atmosphere for
more than a century and the effects on climate come through with a lag,
temperature and sea level will continue to rise during the twenty-second
century, even if we stabilise emissions soon. Most of the damaging consequences
of climate change are associated with water in some shape or
form, including droughts, floods, storms, and sea level rise. --------------------7.4 The Earth's Natural Systems--- A blanket around the Earth--- We live in a greenhouse -----------------
Life on Earth depends on energy coming from the sun. About half the light reaching Earth's atmosphere passes through the air and clouds to the surface, where it is absorbed and then radiated upward in the form of infrared heat. About 90 percent of this heat is then absorbed by the greenhouse gases and radiated back toward the surface, which is warmed to a life------supporting average of 59 degrees Fahrenheit (15 degrees Celsius).

Why an ice age occurs every 100,000 years?—(1) the expansion and contraction of Jupiter and Saturn gravitational pull on the solar system every 100,000 to 413,000 years as the planets orbit around the Sun, This is part of the cycle and system of ALLAH for this solar system and Science itself is apart of that system ---(Milankovitch cycles-Eccentricity) The gravitational pull of Jupiter and Saturn on the Earth. ---Science has struggled to explain fully why an ice age occurs every 100,000 years.

All of these factors have played a major role in the past nature system of climate changing.(4) And the forth is the damage to the ozone layer, Which has had an Effects on the Environment, An Effects on Human Health, An Effects on Plants life, An Effects on Marine Ecosystems, And Effects on Biogeochemical Cycles, And Effects on Materials,----

-----We have to remember that science was created so man could study the creation! Science is the method that is used to study creation ---
Starting with the ice ages that have come and gone in regular cycles for the past nearly three million years, there is strong evidence that these are linked to regular variations in the Earth’s orbit around the Sun, the so-called Milankovitch cycles ( Jupiter and Saturn gravitational pull on the solar system ). These cycles change the amount of solar radiation received at each latitude in each season (but hardly affect the global annual mean), and they can be calculated with astronomical precision. There is still some discussion about how exactly this starts and ends ice ages,But only ALLAH knows!, And many studies suggest that the amount of sum-mer sunshine on northern continents is crucial: if it drops below a critical value, snow from the past winter does not melt away in summer and an ice sheet starts to grow as more and more snow accumulates. Climate model simulations confirm that an Ice Age can indeed be started in this way, while simple conceptual models have been used to successfully ‘hindcast’ the onset of past glacia-tions based on the orbital changes. The next large reduction in northern summer insolation, similar to those that started past Ice Ages, is due to begin in 30,000 years.
Although it is not their primary cause, atmospheric carbon di-oxide (CO2) also plays an important role in the ice ages. Antarctic ice core data show that CO2 concentration is low in the cold gla-cial times (~190 ppm), and high in the warm interglacials (~280 ppm); atmospheric CO2 follows temperature changes in Antarctica with a lag of some hundreds of years. Because the climate changes at the beginning and end ofice ages take several thousand years-

most of these changes are affected by a positive CO2 feedback; that is, a small initial cooling due to the Milankovitch cycles is subsequently amplified as the CO2 concentration falls. Model sim-ulations of iceage climate yield realistic results only if the role of CO2 is accounted for.
During the last ice age, over 20 abrupt and dramatic climate shifts occurred that are particularly prominent in records around the northern Atlantic These differ from the gla-cial-interglacial cycles in that they probably do not involve large changes in global mean temperature: changes are not synchro-nous in Greenland and Antarctica, and they are in the opposite direction in the South and North Atlantic. This means that a major change in global radiation balance would not have been needed to cause these shifts; a redistribution of heat within the climate system would have sufficed. There is indeed strong evidence that changes in ocean circulation and heat transport can explain many features of these abrupt events; sediment data and model simula-tions show that some of these changes could have been triggered by instabilities in the ice sheets surrounding the Atlantic at the time, and the associated freshwater release into the ocean.
Much warmer times have also occurred in climate history----but never like what we are experiencing now! When the Earth was first created it was probably completely free of ice sheets for millions of years (geologists can tell from the marks ice leaves on rock), unlike today, when Greenland and Antarc-tica wereice-covered. If the entire 2,850,000 cubic kilometres (684,000 cu mi) of ice were to melt as it is doing, it would lead to a global sea level rise of 7.2 m (24 ft).

It was once thought (and that was only six years ago) that the glaciers would be self-sustaining even in a warming world because of size and so on.
We now know that not only are the edges melting fast, but the surface melt is seeping through the ice to lubricate the junction between the glacier and the rock underneath. This is the unexpected factor that has turned scientific attention onto this escalating problem. ---
It appears that the Greenland ice is shot through with crevices, tunnels and faults through which the melting upper surface can penetrate right through the glacier, and threaten to break the attachment between the ice and the rock base.

When this happens much of this mountain of water will flow into the sea. Already twenty-one of the great glacial masses are moving seawards eight times faster than ten years ago and disintegrating three times faster than in the preceding five years.
It would seem we are on the verge of a major tipping point in climate change, if we have not already reached it. The latest US Navy survey suggests there will be no sea ice left in the Arctic summer by 2025. This has been unprecedented within the entire record of human species.-
The Greenland, Alaskan and West Antarctic ice sheets together hold about 25% of the fresh water on the planet. The effects of the collapse of either ice sheet would be huge. Once you lost one of these ice sheets, there's no putting it back for thousands of years, if ever.
If they disintegrate, sea level could rise nearly 20 meters, possibly in only one decade. This would swamp most cities and ports, as well a much of the best agricultural land. Where now 6 billion people?

----The Greenland Ice Sheet is sometimes referred to under the term inland ice, or its Danish equivalent, indlandsis. It is also sometimes referred to as an ice cap.----Melt extent in Greenland was above average in 2016, ranking tenth highest (tied with 2004) in the 38-year satellite record. Melt area in 2016 was slightly greater than in 2015, which ranked twelfth. However, near-average to below-average coastal snowfall levels that exposed bare ice earlier in the melting season, combined with warm and sunny conditions at lower elevations, led to high overall ice loss from runoff. -Data on greenhouse gas abundances going back beyond a million years, that is, beyond the reach of antarc-tic ice cores, are still rather uncertain, but analysis of geological--------------------------------------------------samples suggests that the warm ice-free periods coincide with high atmospheric CO2 levels. On million-year time scales, CO2 levels change due to tectonic activity, which affects the rates of CO2 exchange of ocean and atmosphere with the solid Earth. See Box 6.1 for more about these ancient climates.
Another likely cause of past climatic changes is variations in the energy output of the Sun. Measurements over recent decades show that the solar output varies slightly (by close to 0.1%) in an 11-year cycle. Sunspot observations (going back to the 17th cen-tury), as well as data from isotopes generated by cosmic radiation, provide evidence for longer-term changes in solar activity. Data correlation and model simulations indicate that solar variability and volcanic activity are likely to be leading reasons for climate variations during the past millennium, before the start of the in-dustrial era.
These examples illustrate that different climate changes in the past had different causes.( ) The fact that natural factors caused climate changes in the past does not mean that the current cli-mate change is natural. By analogy, the fact that forest fires have long been caused naturally by lightning strikes does not mean that fires cannot also be caused by a careless camper. FAQ 2.1 addresses the question of how human influences compare with natural ones in their contributions to recent climate change.-----------------------

Human activity–now primarily fossil fuel combustion– has increased carbon dioxide concentrations from °280 to 355 mL/L since 1800; the increase is unique, at least in the past 160 000 yr, and several lines of evidence demonstrate unequivocally that it is human—caused. On This Earth, human activities are changing the natural greenhouse,
Burning of fossil fuels causes an excessive build up of carbon dioxide (Greenhouse gases) in the atmosphere increasing global warming."Greenhouse gases effect" warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."Gases that contribute to the greenhouse effect include:Water vapor:Carbon dioxide (CO). :Methane.:Nitrous oxide:Chlorofluorocarbons (CFCs).: ----------------------Human activities has jeopardize Earth’s natural systems,cycles and health of future generations

Would YOUR house be underwater? Terrifying map reveals the devastation that would be wrought if all the world's ice melted
The Earth contains around five million cubic miles of ice and 80 per cent of this is in East Antarctica icesheet alone
Scientists believe it would take more than 5,000 years for all the Earth’s ice to melt under natural circumstances
Earth hasn't been ice-free since the Eocene epoch - a period of increased temperatures 34 million years ago
If this was repeated, sea levels could rise by 216 feet changing shorelines and engulfing entire cities worldwide
National Geographic has created a series of maps showing what continents would look like if the Earth’sice continue to melted
Ice sheets surrounding the North and South poles make up 10 per cent of our entire planet’s surface, and it’s thought Earth contains five million cubic miles of frozen water - so what would happen if it all melted? National Geographic has created a series of interactive maps demonstrating the catastrophic effect Earth’s ice could cause if it melted and flowed into the oceans and seas. This could cause sea levels to rise by 216 feet, devouring cities and even countries all the while drastically altering how continents and coastlines look, and wiping out entire populations. ------- Terrifying map reveals the devastation that would be wrought if all the world's ice melted --------------------
The last time the Earth was ice-free was 34 million years ago during the Eocene epoch. If this happened again with this global warming , the entire Atlantic seaboard as we know it, in the U.S and around the world would vanish, wiping out Florida and the Gulf Coast. While the hills in San Francisco would become islands and San Diego would be lost forever
The ice sheets in Greenland and west Antarctica shrank significantly during the epoch and if Only ALLAH knows the full truth of this matter were to rise in a similar manner again as they are doing, the ice sheets across the regions could disappear into the sea completely by 2070.
If these sheets melted, it would create a knock-on effect for the rest of the world.
In Europe, for example, cities including London and Venice would be lost underwater, as would the whole of the Netherlands and most of Denmark. It would also cause the Mediterranean to expand and swell the Black and Caspian Seas.

The EPA claims that overall ice reduction depends on several factors, including the rate at which levels of greenhouse gases rise and how global temperatures react to this increase in gas.- During the 2014 - 2015 winter there was less ice in the Arctic than during any winter since measurements were made by satellite (Hackman, 2015). This finding reinforces the prediction that the Arctic will be completely free of iceduring summers by about 2040. As the Earth warms the ice starts melting sooner and is melting faster. A consequence of this is the zooplankton now contains a lot less fat. This affects the fish that feed upon the zooplankton, the seals that feed upon the fish, and then the polar bears that feed upon the seals. The whole food chain is being disturbed by a warming Earth. Humans will also be badly affected by the many changes that will take place in the Arctic and elsewhere. ------------The largest concentrations of ice on Earth are found in Greenland and Antarctica, pictured. Warming oceans are already melting the floatingice sheet in west Antarctica and since 1992, National Geographic reports the sheet loses around 65 million metric tonnes each year. If they melted it could cause the sea levels to rise globally by 216 feet
This rise in greenhouse gases is caused by humans, as National Geographic explained: ‘If we burn all the Earth’s supply of coal, oil, and gas, adding some five trillion more tonnes of carbon to the atmosphere, we’ll create a very hot planet with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58. Large swaths of it might become too hot for humans.’
This would make the Earth ice-free for the first time in 34 million years.

If this happened, the entire Atlantic seaboard would vanish, and would be lost forever.
In the east, China and Bangladesh would both be completely flooded, wiping out around 760 million people based on current population levels. The coastlines of India would also be reduced.
Whereas in South America, the Amazon Basin and the Paraguay River Basin would both become Atlantic inlets and this would wipe out Buenos Aires, coastal Uruguay, and some of Paraguay. ----------
The only areas that would survive are mountainous stretches along the Caribbean coast and in Central America.
The other continents would escape a little more lightly, but would still be affected.
In Africa, for example, Egypt, Alexandria and Cairo would be flooded but the continent wouldn’t lose as much of its land to the rising seas. National Geographic claims the Earth’s rising heat ‘might make much of it inhabitable’ though. Only ALLAH knows the full truth of this matter!
Australia would gain a new inland sea but it ‘would lose much of the narrow coastal strip where four out of five Australians now live. --------------------------------------------------------------------------------------------------------------------------------------------------------------------
Burning of fossil fuels causes an excessive build up of carbon dioxide (Greenhouse gases) in the atmosphere increasing global warming.------------The Greenhouse gases in the atmosphere trap some of the heat,---- "Greenhouse gases effect"warming that results when the atmosphere traps heat radiating from Earth toward space. -------------------------------- global warming causes and effects--- Human activity–now primarily fossil fuel combustion– has increased carbon dioxide concentrations from °280 to 355 mL/L since 1800; the increase is unique, at least in the past 160 000 yr, and several lines of evidence demonstrate unequivocally that it is human—caused. This increase is likely to have climatic consequences–and certainly it has direct effects on biota in all Earth's terrestrial ecosystems. The global nitrogen cycle has been altered by human activity to such an extent that more nitrogen is fixed annually by humanity (primarily for nitrogen fertilizer, also by legume crops and as a by product of fossil fuel combustion) than by all natural pathways combined. This added nitrogen alters the chemistry of the atmosphere and of aquatic ecosystems, contributes to eutrophiction of the biosphere, and has substantial regional effects on biological diversity in the most affected areas. Finally, human land use/land cover change has transformed one—their to one—half of Earth's ice—free surface. This in and of itself probably represents the most important component of global change now and will for some decades to come; it has profound effects on biological diversity on land and on ecosystems downwind and downstream of affected areas. Overall, any clear dichotomy between pristine ecosystems and human—altered areas that may have existed in the past has vanished, and ecological research should account for this reality. These three and other equally certain components of global environmental change are the primary causes of anticipated changes in climate, and of ongoing losses of biological diversity. They are caused in turn by the extraordinary growth in size and resource use of the human population. On a broad scale, there is little uncertainty about any of these components of change or their causes. However, much of the public believes the causes–even the existence–of global change to be uncertain and contentious topics. By speaking out effectively, we can help to shift the focus of public discussion towards what can and should be done about global environmental change. --------------------

many greenhouse gases, including carbon dioxide, stay in the atmosphere for
more than a century and the effects on climate come through with a lag,
temperature and sea level will continue to rise during the twenty-second
century, even if we stabilise emissions soon. Most of the damaging consequences
of climate change are associated with water in some shape or
form, including droughts, floods, storms, and sea level rise.

--------------------7.4 The Earth's Natural Systems--- A blanket around the Earth--- We live in a greenhouse -----------------
Life on Earth depends on energy coming from the sun. About half the light reaching Earth's atmosphere passes through the air and clouds to the surface, where it is absorbed and then radiated upward in the form of infrared heat. About 90 percent of this heat is then absorbed by the greenhouse gases and radiated back toward the surface, which is warmed to a life------supporting average of 59 degrees Fahrenheit (15 degrees Celsius).

Looks different when zoomed:





Maybe they are expanding and contracting - whilst expanding overall like the gasses and particles in the following video, we know that collision and expansion are related causes of each other due to either disharmony between two combined items - or - an understanding of efficiency when working separtely whilst in tandem (such as cell explosion or and the sun and the moon and the planets which work together to survive in regulation). Similar observations are made in atoms too.



scroll to 4min:37s and then to 6min if you would like to ponder.
The demonstration indicates a timewarp in which the tenure of humankind is a tiny fraction of a short incident in Allah's sight.
There's also a black hole which follows the slipstreams of the primary projectile and simply gargles and spits out every thing it takes in its wake.

The "cliche": "faster than a bullet" takes new dimensions...





The different black holes created all contain differing amounts of energy - implying that the black hole of one particle system can envelop the harmony of another - whilst on larger scale - strengthening the validity of newton's theory on stationary and moving objects in relation to external objects.

Multiple universal time "zones" point to and strengthen some of the recent theories on relativity too.



70.4. The angels and the Spirit ascend to Him (thereby), in a day the measure of which is fifty thousand years (of your normal worldly years).
تَعْرُجُ الْمَلَائِكَةُ وَالرُّوحُ إِلَيْهِ فِي يَوْمٍ
كَانَ
مِقْدَارُهُ
خَمْسِينَ أَلْفَ سَنَةٍ

4. The angels and the Spirit ascend to Him (thereby), in a day the measure of which is fifty thousand years (of your normal worldly years).1

1. "Reaching" God requires traversing great "distances" and ascending innumerable steps. So the stairs of ascent to God, and the measure of the day as being fifty thousand years, imply both our distance from Him despite His infinite nearness to Us, and His indescribable "elevation" and transcendence (see also sūrah 32: 5, note 4). The day may also be referring to the Day of Judgment. In this case, its measure suggests the great distances between the stations or worlds of the Hereafter or both, and the dread and hardships the people of Hell will suffer while they are being driven through these stations and worlds to Hell. In this case, such a great distance constitutes a great threat. As explained in several places in this study, the angels are dutiful in conveying God's commands throughout the universe. They also convey the worship and life-functions of all creatures before the Presence of God. So, by the stairs of ascent and a day measuring fifty thousand years, the verse may be referring to this fact. The Spirit mentioned in verse 4 is either Gabriel or another angel-like being that is greater than the angels. According to Imam Ghazzālī, he is an angel (or angel-like being) whom God employs in breathing an individual's spirit into that individual's body. Bediüzzaman Said Nursi maintains that there is a spirit representing every thing, every being. So the Spirit may be the being responsible for all the spirits.

22.47. They challenge you to hasten the coming upon them of God's punishment (with which they are threatened). Let them know that God never fails to fulfill His promise; but a day with your Lord is like a thousand years in your reckoning.

وَيَسْتَعْجِلُونَكَ بِالْعَذَابِ وَلَن يُخْلِفَ اللَّهُ وَعْدَهُ وَإِنَّ يَوْماً عِندَ رَبِّكَ

47. They challenge you to hasten the coming upon them of God's punishment (with which they are threatened). Let them know that God never fails to fulfill His promise; but a day with your Lord is like a thousand years in your reckoning.15

15. This verse touches on certain important facts from the perspectives of astrophysics and the sociology of history.

First of all, it draws attention to the relativity of time. A time or duration which people see as being long may be very short in the sight of God. In addition, God does not consider time as people do. He is not contained by time or space, and His Wisdom that directs things and events considers each thing and event both as an individual entity in and as an indispensable part of the general fabric of creation and history. As each thing in the universe has an intrinsic relationship with not only every other thing individually, but also with the whole universe at the same time, so, too, is each event in human history interrelated with every other event individually and with the whole of history. Human beings cannot grasp this relationship; they cannot know the past perfectly, grasp the present completely, nor guess the future well. The wheel of both the universe and history does not revolve according to the desires of human beings.

Secondly, a day for humanity is the time it takes the earth to make a single rotation around itself. The earth has another day, which consists in its revolution around the sun. This day lasts 365 days according to the reckoning of a day by humanity. So, too, does every other planet and all systems, like the solar system, have a day that is peculiar to each. This means that the concept of a day differs according to the planets and the systems.

Thirdly, God has laid out certain laws concerning human social life. He judges a community according to the creeds, world-view, and conduct of, at least, the majority. Thus, there are eras and ages in human history and eras of foundation, rising, fall, and decline for communities and civilizations. Thus, we can consider the whole life of a state or community or civilization as a day; the most important changes in the history of humanity usually occur once in 1,000 years. This verse also alludes to this fact.


http://mquran.org/content/view/2642/1/


We can see that the fifty thousand year per day speed of the angels is provided as an accurate calculation, and that the apparent one thousand year per day statement is relative to people and not necessarily calculably accurate from every perspective.

The world will end in a few hundred years, we'll never see another ice age so isn't that useless info just like how far is the planet keppler from earth?

It's all just theory too so we cannot say with certainty 'this is the system Allah created...'
