and earlier this year, a temperature above 20 celsius was recorded for the first time in antarctica.of climate change is less discernible than in the arctic. a vast cold ocean and strong winds tend to isolate it from any of these warmer air intrusions and natural climate cycles here may obscure some of the effects of human—induced change. but what is clear is that the ice sheets and ice shelves are losing mass. billions of tonnes of ice has been lost from antarctica in recent decades and its future responses to a warming world could have global consequences. so, why is it that the poles are warming so much quicker than other parts of the globe? that is a question i put to professor martin siegert, the co—director of the grantham institute of climate change and environment at imperial college london. there are a number of reasons for why that might be and an obvious one to consider is the change in the amount of snow and ice in the arctic is going down. and as that happens, a very white and reflective surface, which is the snow and ice, which bounces the sun's energy back out into spa

finally, a worrying new report has revealed the extent of ice melt in antarctica.enough mass to fill the grand canyon with water. the ice shelves we‘re seeing melting in this study are not going to raise to sea level in themselves because they‘re actually already sitting in the water. they‘re already floating. the sea level rise comes when those ice shelves reduce the restraint that they exert on the rest of the antarctic ice sheet, which then flows faster into the ocean, causing sea level rise. the effects of all this cold, fresh water entering the deep sea around antarctica are likely to be felt far beyond the polar south. the ocean plays a major role in controlling the climate around the world. adding a lot of cold fresh water to the ocean changes the way it can transport heat. and that can change global climate and maybe potentially change rainfall patterns around the world. is that what scientists mean when they describe antarctica as the world‘s thermostat? that what happens to that ice and in that ocean is shifting weather patterns all around the world ? yea
