Contemplating the IARC-JAXA graph

One of the ~350 or so blogs I subscribe to is Arctic Sea Ice by Neven. Today, he put up a post highlighting new daily data from IARC-JAXA, a collaboration between the International Arctic Research Center (IARC) at the University of Alaska-Fairbanks and the Japan Aerospace Exploration Agency (JAXA).  Check it out. Here’s a couple of things I was struck by: The annual variation between summer and winter ice cover …

AGU 2011, day 2

In the interest of conveying a sense of the sort of stuff that goes on a large science conference like the AGU Fall Meeting, I’ll resume my narrative where I left off with yesterday’s description. I began by swinging by the press room where I grabbed a complimentary breakfast, then headed down to the “early earth” session where I got a review on zircons of Hadean and Archean age. Then …

AGU 2011, day 1

I got to San Francisco on Saturday afternoon, flying in on the same flight from DC as Rob Simmon and Maria-José Viñas. MJ and I took the BART downtown, and then met up with Jess Ball for Thai dinner and a yummy dessert of banana wrapped in roti with Nutella and coconut ice cream. Then, jet lag informing me it was time for rest, I went to bed. I had …

ACM

From “Volcanic Versus Anthropogenic Carbon Dioxide” by Terry Gerlach in the June 14, 2011 issue of EOS: Human activities emit ~135 times as much carbon dioxide as the world’s volcanoes? Holy cow.

Words matter

A table from the article “Communicating the Science of Climate Change,” by Richard C. J. Somerville and Susan Joy Hassol, from the October 2011 issue of Physics Today, page 48: There’s a lot to ponder in this table. It strikes me as an important document – a compilation of one of humanity’s most tragic miscommunications. You can click on it to make it bigger – large enough that you could …

A graphical dalliance

I read an article in the current issue of Physics Today with interest. It deals with the nature of scientific controversies, as percieved by the public and by specialists in the field in question. The author, Steven Sherwood, compares the origin of the ideas of a heliocentric solar system, general relativity, and human influence on the Earth’s climate. Each of them follows a similar pattern, he argues, with the initial …

A dismaying course, part I: climate change

You may have heard that the Republican party has been embracing non-scientific and anti-scientific positions lately. National Public Radio compiled a bunch of quotations reflecting this trend on their website yesterday. I thought I might take a moment here on the blog to critique their statements (both pros and cons), and then reflect on why, in total, the Republican trend towards anti-science strikes me as a dismaying course for my …

The tricky business of SRM

Yesterday afternoon, I went to the Longworth House Office Building on Capitol Hill to attend a briefing arranged by the American Meteorological Society on the topic of geoengineering as a response to climate change. The two speakers, Ken Caldeira and David Keith, argued that the U.S. should invest heavily in geoengineering research, so we can figure out what’s safe and what’s irresponsible before we actually make any decisions about which …
