A few degrees warmer doesn sound that bad, whats the big deal?
It depends where you live. There are two parts to this issue: First, the temperature increases from global warming will not be evenly distributed – some areas will only get slightly warmer, while others will see large changes. Secondly, there are parts of the world where a small temperature rise can make a really big difference. For instance, big portions of the world’s population (like the western USA or northern India) rely on winter snowfall to provide summer water supplies. A small difference in temperature can mean a big difference in how much snow collects during the winter. This can lead to wintertime floods and summertime droughts. What has happened already is serious and it will probably pale in comparison to future changes. The actions we take today will determine what sort of world our children will inherit.
