Antartica Melting?

Scientists say that the West Antarctic ice sheet may take upto 1000 years to melt, which is good news...sort of, but it has collapsed before when CO2 levels reached 400 ppm in the atmosphere. This is a bit of a worry, as what the article doesn't mention is that CO2 levels are already at 385 ppm, up from 315 ppm since accurate measurements began in 1958. CO2 levels are rising at an average of around 1.5 ppm a year, which means 400 ppm could be reached in just 7 years time....What will happen to the ice sheet then, as this level of CO2 will surely bring with it an increase in sea temperature....?

As for Polar bears, which live in the Arctic, not the Antarctic, they appear to be getting smaller. The melting ice cap there, means they can't catch as much food as they used too, which is affecting their weight...

Antarctica melting?

This article refers to the potential collapse of the Wilkins Ice Shelf in Antartica, which may melt once CO2 levels get to 400 parts per million, a level that may be reached by 2050. This may be the best case scenario however as CO2 levels now stand at 385 ppm, and are increasing at around 1.7-2.3 ppm per year approx, meaning 400 ppm could be reached by 2017.... much sooner than suggested..?

Global Warming News

Future looks bleak for all of us as latest super computer forecast suggests that there is little better than a 50/50 chance of keeping world temperatures below disastrous thresholds of + 2 degrees above pre-industrial age, even if unprecedented reductions in Co2 levels are made immediately. World temperatures have already increased by 0.75 degrees since pre-industrial times. An increase of 2 degrees will have serious consequences for all of humanity... read more
