Dr. Vicky Pope, head of climate change predictions at the Met Office’s Hadley Centre, writes in the UK Times that

In a worst-case scenario, where no action is taken to check the rise in Greenhouse gas emissions, temperatures would most likely rise by more than 5°C by the end of the century.

It may be “a worst-case scenario” for rational people like her, but right now even Hadley understands it is better described as the “business-as-usual” case.

After all, the traditionally staid and conservative International Energy Agency annual noted in its World Energy Outlook released last month said, “Without a change in policy, the world is on a path for a rise in global temperature of up to 6°C.” (more…)
