An excellent piece on Dot Earth
today that I can’t recommend highly enough, on sea level rise.
Somebody, please express mail this to Judith Curry:
[NASA Glaciologist Walid Abdalati] said: “It is always a challenge to convey scientific uncertainty (and there is a lot in this case) to the general public. People want ‘the answer,’ and when you start to explain why ‘the answer’ is not as obvious as they would like, it is easy to lose them. Plus, there is so much hype made of uncertainty by skeptics, that it gets spun into the idea that scientists don’t really know what they are talking about and don’t have the answers.
“At the end of the day, you can be 90% confident of something, and all people will hear is that you aren’t certain about what you are saying. This is why the debate is often cast in extremes, rather than an honest consideration of the data. It is really too bad, because an honest consideration of the data is still quite compelling.”
Revkin also has a Tumblr on the side, where he displays this new hockey stick:
That’s from Andrew C. Kemp, Benjamin P. Horton, Jeffrey P. Donnelly, Michael E. Mann, Martin Vermeer, and Stefan Rahmstorf: Climate related sea-level variations over the past two millennia PNAS 2011; June 20, 2011, doi:10.1073/pnas.1015619108
You expected, what, now?
