Even Tony Blair gets it

Even Tony Blair seems to understand that climate change and global warming are serious issues.

Tony Blair warns that the impact of climate change may be more serious than previously thought in a new government report on global warming published today.

The report raises fears that both the Antarctic and Greenland ice sheets are likely to melt, leading to a devastating rise in sea levels.

It warns of large-scale and irreversible disruption if temperatures rise by more than 3C (5.4F) - well within the range of climate change projections for the century.

Meanwhile, George Bush seeks to silence US scientists who have reached the same conclusion.
