This is my comment in reply to a post by Dr Tamsin Edwards on her blog ‘All Models Are Wrong’ entitled Nine Lessons and Carols in Communicating Climate Uncertainty. I have submitted this comment on Tamsin’s blog.
Thanks, Tamsin, for this article. It is a pity, though, that what the IPCC said about the attribution of global warming in AR4 and AR5 is not reported correctly. Continue reading
…despite what the Guardian says. Update: …as the Guardian now agrees.
[Update: 9 Oct 2013 13.01 pm: The headline and first paragraph of the article have now been changed following email correspondence between Fiona Harvey and me. Credit to Fiona and the Guardian for this response. The links now lead to the updated version which can be compared with the screenshot below. Further update: See also http://www.newssniffer.co.uk/articles/690315/diff/0/1 for a side-by-side comparison.]
Fiona Harvey’s article in the Guardian on 3 October 2013 Ocean acidification due to carbon emissions is at highest for 300m years misrepresents the scientific literature. This error has propagated across the Twittersphere.
(H/T Latimer Alder for the tweet that alerted me to this article)
Harvey wrote (my emphasis)
‘The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday.
In the starkest warning yet of the threat to ocean health, the International Programme on the State of the Ocean (IPSO) said: “This [acidification] is unprecedented in the Earth’s known history. We are entering an unknown territory of marine ecosystem change, and exposing organisms to intolerable evolutionary pressure. The next mass extinction may have already begun.” It published its findings in the State of the Oceans report, collated every two years from global monitoring and other research studies.’
My garden is at its best in May, so I thought I’d post a recent photo of the pond. The pond was built at the end of 2007 and mostly planted in 2008. It’s home to tadpoles, dragonflies, snails and water beetles.
In the Sunday Telegraph today, Christopher Booker said that a last minute amendment went into the Energy Bill on Tuesday 4 June 2013.
By 2020, it said, Britain must reduce its electricity use by “103 terawatt hours”, rising by 2030 to “154 terawatt hours”.
This is incorrect. No such amendment was included in the bill that had its first reading in the Lords on Thursday 6 June 2013. Continue reading

The claim that some parts of Africa ‘have become 3.5 degrees hotter in the past 20 years’ has now been removed from the commentary of the BBC Africa documentary after Leo Hickman’s investigation − see also my previous post The Power of a Tweet. But where exactly did this 3.5 degree figure come from?
Over the past few months, two of my Tweets have had more impact than I expected…
