1) It is cold enough to sustain ice in these two areas because at those high elevations/latitudes it’s cold but they’re high pressure zones, which means there’s no precipitation (very dry). Since the sun is hitting it at such a ‘low’ angle the light/heat from it is distributed over such a wide area that it really doesn’t make a difference in the temperature. Even in the summers the temperature doesn’t get above freezing. This means that the ice is melting so slowly that by the time it can melt even a little bit, it’s already started to get colder and is refreezing, remaining as ice.
2) Typically we find the tropical rainforest biome at 0-10° latitude. It’s a low pressure zone because the sun is hitting it directly at a 90° angle. Since it’s

CH4 traps the suns heat around 20 times more than CO2 (one website says 100 times more in every five years while another says it’s 100 times more per year so I wasn’t sure which one to go with). Although most of the carbon that’s released will be CO2, since methane is so good at trapping heat it’s been foretold “that it would trap about as much heat as the carbon dioxide would.” This means that rather than trying to just increase the amount of carbon dioxide in the air we should also, perhaps even more so, cut down on methane emissions.
7) There are two calculations. Due to certain activities that emit carbon it’s been estimated that the melting permafrost roughly equals 15% of those emissions. However that estimate was an understatement. If we don’t change our ways and keep a high fossil-fuel burning rate and the Earth’s temp rose drastically then it would end up equaling 35% of annual emissions created by humans. Although it doesn’t seem like a big increase, in this case, if it is methane being released rather than carbon dioxide it can make a huge difference in what happens to our
