Time magazine posted an interesting photo essay recently describing changes in ice taking place around Antarctica. Climatologists know that the high latitudes (both in the Arctic and Antarctic) are the most likely places to see the impacts of changing climate because of the albedo effect, which affects how much sunlight is absorbed by the ground…

If you are interested in learning more about how climate models work, you can check out this fairly long and detailed explanation from Carbon Brief at https://www.carbonbrief.org/qa-how-do-climate-models-work. In many ways the climate models are similar to weather forecast models except that weather forecast models are designed to work really fast (to get the forecasts out on…

Here’s an interesting story about a group led by University of Arizona scientists studying jet stream position using tree ring analysis. By looking at the density of wood produced late in the growing season, the scientists were able to produce a long history of high-summer jet stream locations dating back to 1725. This time series…

Here’s an interesting statistic from Brad Panovich, meteorologist, on Twitter and Facebook: The last two weeks, from December 25 through January 7, have been the coldest on record for many locations in the Southeast. The ranking map from the Southeast Regional Climate Center shows how widespread the #1 rankings are across the region. You can…

Over the last few years, atmospheric methane has increased at a high rate. Methane is a potent greenhouse gas, much more powerful than carbon dioxide, so attempts to understand where it is coming from can help us work on solutions that fight the increase in warming that results from increases in methane. This article in…
