The US Synthesis Report and the Search for Climate WMD

White House advisers greeted the new Climate Change Science Program(CCSP) assessment report like Bush advisers would have greeted a favorable report on WMD. Jane Lubchenco, administrator of the National Oceanic and Atmospheric Administration said: “It’s not just a problem for the future. We’re beginning to see the impact on our daily lives.” On the left […]

The UK Met Office Deepens The Moat

Deepening moats has been a lively topic in UK politics recently. One British MP expensed the public for the cost of deepening the moat at his castle and has been forced to resign. We discussed FOI and the MP expense scandal recently. We have, of course, followed with some considerable amusement the contortions of the […]

A New Sea Ice Thread

Prior post here. Next post here Sea ice threads always seem to be popular. For people interested in handling data themselves, I’ve updated my utility functions for reading sea ice data here. It contains methods for accessing JAXA, monthly NOAA and NSIDC binary. (The latter works but I haven’t verified the turnkey version. Jeff Id […]

Today's GISS Conundrum

Jean S has written to me with another installment in our ongoing series about GISS conundrums. The puzzle starts with plotting the annual (Dec-Nov) GISS 1200 km anomaly map for the period 1991-2008 (here using 1961-1990 reference.) As you see, there is a Gavinesque red spot offshore Ecuador. Radio buttons generate plots at GISS here. […]

Pielke Jr on Models

The National Post in Toronto led off a week of columns on questionable science, leading up to the awarding of the prestigious Rubber Duck Award (named after a Canadian Environmental Defense campaign against homicidal rubber ducks) with a column by Pielke Jr. on models. RP leads with a discussion of the role of models in […]

Chucky Returns, Part IV

Suzanne Goldenberg writes today: The Obama administration is poised for its most forceful confrontation with the American public on the sweeping and life-altering consequences of a failure to act on global warming with the release today of a long-awaited scientific report on climate change. Figure 1. Photoshopped picture of a flooded house in First Draft […]

TAS vs TOS

My new script for scraping KNMI model makes it very convenient to look at model data without a lot of setup overhead. Up till now, I’d only downloaded air temperature data (tas) and I tested downloading SST data (tos). KNMI’s collection of tos data is unfortunately quite spotty and this information is not consistently available. […]

More on Retrieving KNMI Data

I’ve done a considerable upgrade to my function for retrieving model data from KNMI within R. This builds on the KNMI webpage but IMO is a considerable enhancement of it. I’ve made the script available here . The function read.knmi.models is built as an emulator of the radio buttons. Geert’s radio buttons (if I’m understanding […]

A Partial Victory for the R Philosophy

Obviously I think that R is a great language. But one of the reasons that it’s great is because it’s open source and because of the incredible energy and ingenuity of the packages contributed by the R Community for the use of others. In a real sense (as opposed to a realsense), this sort of […]

Cloud Super-Parameterization and Low Climate Sensitivity

“Superparameterization” is described by the Climate Process Team on Low-Latitude Cloud Feedbacks on Climate Sensitivity in an online meeting report (Bretherton, 2006) as: a recently developed form of global modeling in which the parameterized moist physics in each grid column of an AGCM is replaced by a small cloud-resolving model (CRM). It holds the promise […]
