House and Senate committee hearings

Filed under: — group @ 30 January 2007

There are two hearings today from the new congress that are of relevance for RealClimate readers:

The House Oversight Committee is having hearings on the possible suppression of climate change science by the administration (streaming from here). Witnesses include Drew Shindell (NASA GISS), Roger Pielke Jr. and R. Piltz. Update: Full hearing video available at C-SPAN.

The Senate EPW Committee is having an open forum for senators to discuss climate change legislation (streaming from here).

Stern Science

Filed under: — group @ 28 January 2007 - (Français) (Português)

Halldór Björnsson, William Connolley and Gavin Schmidt

Late last year, the UK Treasury’s Stern Review of the Economics of Climate Change was released to rapturous reception from all sides of the UK political spectrum (i.e. left and right). Since then it has been subject to significant criticism and debate (for a good listing see Rabbett Run). Much of that discussion has revolved around the economic (and ethical) issues associated with ‘discounting’ (how you weight welfare in the future against welfare today) – particularly Nordhaus’s review. We are not qualified to address those issues, and so have not previously commented.

However, as exemplified by interviews on a recent Radio 4 program (including with our own William Connolley), some questions have involved the science that underlies the economics. We will try and address those.

The Human Hand in Climate Change

Filed under: — mike @ 23 January 2007

Kerry Emanuel (whose influential scientific work we’ve discussed here previously) has written a particularly lucid and poignant popular article on climate change for the literary forum “Boston Review”. The article is entitled Phaeton’s Reins: The human hand in climate change. We thought it worth passing along.

When the mites go up…

Guest Commentary from Andy Baker, U. of Birmingham

It doesn’t seem obvious really. Going underground into caves, removing stalagmites and analysing their isotopic composition isn’t the first thing you would do to look for past climate information. But for nearly 40 years, there has been an active, and growing research community that investigates the climate records preserved in these archives. Stalagmites have recently received high profile use in climate reconstructions, for example records from China and Norway have featured in Moberg’s last millennium temperature reconstruction; in a northern hemisphere temperature reconstruction of the last 500 years and even been debated here on RealClimate. So it seems timely to review why on (or even under) earth should research go underground to look at surface climate.

Calling All Science Teachers

Filed under: — group @ 15 January 2007

“An Inconvenient Truth,” the Davis Guggenheim documentary on global warming starring Al Gore’s presentation on the subject, provides an accurate, engaging, accessible, thought-provoking and (at times) even humorous introduction to one of the most important scientific issues of our time ( see our review of the movie). In some countries, viewing “An Inconvenient Truth” has actually become a required part of the science curriculum, and with good justification, we think. Given that the DVD is currently selling for $19.99 through, you’d think that the National Science Teachers’ Association ( NSTA) would jump at the chance to quickly get 50,000 free copies quickly into the hands of their members. Yet, when Laurie David, one of the producers of the film, made this offer to NSTA last November, it was summarily turned down on the grounds that the NSTA has a 2001 policy against “product endorsement” (as if Laurie David were trying to shop some new deodorant to high school science teachers). What in the world is going on here?

Before continuing with the history of NSTA’s bizarre decision, let us provide you with the most important information: Up to 50,000 US science teachers can receive a free copy of the DVD by filling out a simple request form here . The deadline for requesting your copy is January 18, so if you want a copy, take a few minutes to put in your request right away.
