Doomed, I tell you, we are all doomed.
Prof Watson, the chief scientific adviser to the Department for the Environment, Food and Rural Affairs, said the EU commitment to limit any temperature rise to 3.5F (2C) is ambitious and Britain should instead plan for a worst-case scenario.
"There is no doubt that we should aim to limit changes in the global mean surface temperature to 2C above pre-industrial," he told the Guardian.
"But given this is an ambitious target, and we don't know in detail how to limit greenhouse gas emissions to realise a 2 degree target, we should be prepared to adapt to 4C."
Of course there is a possibility that temperatures over some undetermined future timescale may rise 4 degrees, they may also fall four degrees, in fact they may do nearly anything - the sceptic argument is what is the real probability looking at as much hard science as we can and what are the costs of any preparation, can they be justified.
