Some of the scientists, I believe, haven’t they been changing their opinion a little bit on global warming? There’s a lot of differing opinions and before we react I think it’s best to have the full accounting, full understanding of what’s taking place.” That was five years ago Al Gore, same debate same question: I disagree that we don’t know the cause of global warming. I think that we do. It’s pollution, carbon dioxide and other chemicals that are even more potent. Look, the world’s temperatures going up, weather patterns are changing, storms are getting more violent and unpredictable. And what are we going to tell our children? That was five years ago Yesterday: Global warming 'past the point of no return' By Steve Connor, Science Editor Published: 16 September 2005 A record loss of sea ice in the Arctic this summer has convinced scientists that the northern hemisphere may have crossed a critical threshold beyond which the climate may never recover. Scientists fear that the Arctic has now entered an irreversible phase of warming which will accelerate the loss of the polar sea ice that has helped to keep the climate stable for thousands of years. They believe global warming is melting Arctic ice so rapidly that the region is beginning to absorb more heat from the sun, causing the ice to melt still further and so reinforcing a vicious cycle of melting and heating.
