Snowstorms in a Warming World
On March 2 snowstorms hit the eastern seaboard, coinciding with a widely publicized protest against the coal industry in Washington DC . This garnered some attention, with Time noting the irony of people chanting about global warming while shivering in the cold and snow. One might wonder if a March snowstorm is inconsistent with a…

A Q+A on climate risk management in practice
I had the pleasure of interviewing Graeme Hammer from the Univ. of Queensland a while back about his experiences incorporating climate information into the decision-making process of farmers in Australia. Something he emphasized a number of times during our conversation: simply giving out additional information such as seasonal forecasts isn’t likely to solve any problems…

Deep Thoughts on Deep Convection
Deep convection refers to the thermally driven turbulent mixing that moves air parcels from the lower to the upper atmosphere.

Dr. Larissa Back, a NOAA…

Giving new meaning to the word “hybrid”
Last week, we learned that the Obama EPA will conclude that carbon dioxide is an air pollutant as defined by the Clean Air Act (CAA). But a so-called endangerment finding on CO2 won’t lead to comprehensive CAA regulation, as I argued a few posts ago. Rather, the Obama administration will use the CAA as a…

La Niña Conditions to Continue?
According to Tony Barnston of the IRI, the La Niña conditions which began in December are likely to continue until mid-March. Click on the graph below for a better look at the probabilistic forecast. As mentioned in an earlier post, La Niña events are characterized by unusually cold sea surface temperatures (SST) in the central…

Oil sands on Obama’s Canada agenda
President Obama visits Canada today, and climate change is expected to be on the agenda. In Canada, the big issue is the development of the Albertan oil sands, which promise greater energy independence from the Middle East (a longtime U.S. goal) but also greater emissions as a result of the energy-intensive process of extracting oil from…
