I've had a couple of angry emails - rather than public comments - from American readers about my remarks on global warming. Basically saying it's all a fuss about nothing and why am I supporting the unpatriotic lefty pinkos etc etc.
Well, the recent report was the result of a consensus amongst a large group of scientists - and so, necessarily, rather conservative; they all had to agree, after all.
Then the politicians waded in with the scissors. American political representatives cut this crucial sentence: "North America is expected to experience locally severe economic damage, plus substantial ecosystem, social and cultural disruption from climate change related events." It could hardly be more clear.
You can download the full report and you can also read this piece on the political and other influences on the science in the report, and in other coverage, from The Guardian.
Next time... back to plants in the garden, perhaps.
