In an enthusiastic, if last-minute bid for a Nobel-prize, the UK Health secretary claims that fatness is as great a threat as climate change.

Must try harder, Alan Johnson.

Unless of course, Mr Johnson is implying that all the fat people in the UK will do something along the lines of knocking the Earth out of its normal orbital path, plunging it into months of unbearable heat, followed by months of intolerable cold.

To be honest, I doubt this is likely. I think that Alan Johnson is just trying to get some media attention by slinging empty soundbites around, if he gets to re-direct some public funds then it is just a bonus for him… Am I too cynical?
