Scientists have long agreed that climate change could have a profound impact on the planet; from melting ice sheets and withering rainforests, to flash floods and droughts.
Now a team of climate experts has ranked the most fragile and vulnerable regions on the planet, and warned they are in danger of sudden and catastrophic collapse before the end of the century.
Join the board. So, just where ARE those areas?
Although the scientists cannot be sure precisely when each region will reach the point of no return, their assessment warns it may already be too late to save Arctic sea ice and the Greenland ice sheet, which they regard as the most immediately in peril.
Our grandchildren won't know what ice is.
The next most vulnerable area is the Amazon rainforest, where reduced rainfall threatens to claim large areas of trees that will not re-establish themselves. The scientists also expressed concerns over the Boreal forests in the north, and have predicted that El Niño, the climate system which has a profound impact on weather from Africa to North America, will become more intense.
Oh, boy. This global warming is going to screw up the weather all over the world.
The Indian summer monsoon is predicted to become erratic and in the worst case scenario, begin to flip chaotically, unleashing flash floods one year and droughts the next.
Measurements of the western Antarctic ice sheet show the balance of snowfall and melting has shifted and it is now shrinking.
I hope those penguins can swim.
