20,000 years ago the landscape looked very different. Wooly mammoths and sabre toothed tigers roamed the frozen earth - it was of course the ice age. Then, slowly but surely the ice started to melt as temperatures gradually increased. Sea levels rose and a thousand years later, the earth was looking quite different. Today the worldʼs climate is still changing, but this time itʼs happening much more quickly and its probably something to do with us! Temperatures across the world over the last 200 years have been rising faster than ever before and meteorologists believe that this pattern is set to continue unless we do something about it by drastically cutting greenhouse gas emissions (see Conservation Education issue 16).
