Climate Change

Michael Mann has a specialty or two. Climate simulation modeling, analysis of proxy data, the study of global teleconnections, Northern Hemisphere surface temperatures over historic time scales, etc. A while back, Mann’s research interests and activities converged, I assume by some combination of design and chance (as is often the case in Academia) with a…

First Known Climate Change Extinction

When the sea levels rose following the last major glaciation, most rapidly between around 18,000 and 10,000 years ago, somewhat less rapidly until about 6,000 years ago, a lot of interesting things happened. I used to live, and do archaeology in, New England (the one in the US). It was always fun to contemplate George’s…

Calling out the Koch Brothers

Just got this media release: Washington, DC – Today, Monday, from 4:45 p.m. to 6:45 p.m., tomorrow, Tuesday, from 5 p.m. to 7:30 p.m., and throughout the week,* 19 Senators will take to the Senate floor to call out Koch brothers- and fossil fuel industry-funded groups that have fashioned a web of denial to block…

Super Typhoon Nepartak

This is a huge hurricane/typhoon heading quickly, and imminently, towards taiwan. The storm itself is roughly as wide as the island nation is long, so very little will be left unaffected. The storm is at the very high end of the range of storms in size, strength, etc. It is currently equivalent to a Category…

Roughly speaking, we are toast if the Earth’s surface temperatures reach something like 3 degrees C above pre-industrial levels. We have already reached about 1.5 degrees C above pre-industrial, and we will go higher even if we stop adding more greenhouse gasses to the atmosphere, because it takes time for the Earth’s system (the oceans,…

The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy is a great new book by climate scientist Michael Mann and cartoonist Tom Toles. This book serves many purposes. It includes an overview of the basic science of climate change and human caused global warming. It has…

Weather is climate here and now, and climate is weather over the long term. Climate is the large scale process of movement of air and water, and changes in the properties of air and water, on and near the surface of the Earth, the atmosphere, oceans, and ice fields respond to the imbalance of heat…

Based on the best available estimates, which could be better but the satellite broke, the Arctic Sea Ice is melting this year at an unprecedented rate. It is almost like the Earth is warming up or something.

The human release of greenhouse gasses has ultimately caused changes in weather patterns so that major storm systems in the Northern Hemisphere get wetter and move along more slowly, causing significant rainfall events to occur at a much higher rate than previously. This has become a nearly ongoing phenomenon, with major floods in Canada, Colorado,…

Mark Steyn’s Latest Trick

UPSATE. The motion has been denied. Rather hilariously, bt the way. Professor Michael Mann vs. Shock Jock Mark Steyn You all know about the libel suit filed by Professor Michael Mann against Canadian right wing radio shock jock Mark Steyn. Steyn made apparently libelous comments linking Mann, who is widely regarded as the worlds top…
