Global Warming

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…

Trending wetter with time: weather never moves in a straight line, but data from NOAA NCDC shows a steady increase in the percentage of the USA experiencing extreme 1-day rainfall amounts since the first half of the 20th century. Photograph: NOAA NCDC My Apology to Paul Douglas I admit that I do a lot of…

This is a press release that just came across my desk that I thought would be of interest to you. High-drama at low-key follow up to UN Climate Change Agreement in Paris Bonn, Germany – United Nations climate change negotiations today concluded their first session since the adoption of the Paris Agreement in December last…

A cure is found for CCDD

Sea levels are going to rise The amount of carbon dioxide in the Earth’s atmosphere directly and indirectly determines the sea level. The more CO2 the higher the sea level. The details matter, the mechanism is complex, and as CO2 levels change, it takes an unknown amount of time for the sea level to catch…
