What can we do about climate change?

I could rephrase this question. What should we do about climate change. The reason I might rephrase this is because we may not be that sure of what we can do, but we should do something. Or, more accurately, some things. There are a lot of possible things we can do, and we have little…

Mark Steyn and Judith Curry

Two items related only because these two seem to like each other and there are coeval happenings. Mark Steyn and Dr. Michael Mann’s book Michael mann wrote a great book called The Hockey Stick and the Climate Wars: Dispatches from the Front Lines. It really is a good book, I highly recommend it. Mark Steyn…

We have been having a run of very warm months, and according to the GISS database, updated yesterday, September was the warmest on record, and the records go back to the late 19th century. This is global average temperature of the surface. I’ll have more about this later, as other databases are updated. Sometimes one…

Antarctic Sea Ice and Global Warming

Did you ever leave your freezer door slightly open on a humid day only to find chunks of new ice formed at the gap? When that happens, did you conclude “Oh, my freezer is colder than usual, I wonder how that happened?” No. You concluded that you had left the door slightly open, some cold…

What is the role of the ocean’s abyss in global warming?1 I’ve already posted on a study published in Nature Climate change that shows that the amount of extra global warming related heat in the Southern Oceans is greater than previously thought. There is another paper in the same journal by Llovel et al, “Deep-ocean…

The sun warms the Earth’s surface. Additional greenhouse gases and associated positive feedbacks (like, additional additional greenhouse gasses) increase that effect. So, it gets warmer, and by “it” we mean the “surface” of the Earth. This is usually measured as the temperature near the surface across the land and the surface of the sea (Sea…

The American Meteorological Society, in it’s Bulletin of the American Meteorological Society (BAMS), has released a report called “Explaining Extreme Events of 2013 from a Climate Perspective.” Three studies looked at excessive heat in Australia, three at drought or dry conditions in California, and 14 looked at various other extreme events (though some of those…

As you know, I do the occasional science-related interview on Minnesota Atheist Talk Radio, on Radio AM 950. (See this for a list of all, or at least most, of the work I’ve done with that show.) On Sunday October 5th at the ungodly hour of 9:00 AM Central Time, I’ll be interviewing Michael Mann,…

This is about the law suit filed by Michael Mann against the Competitive Enterprise Institute, the National Review, Mark Steyn, and Rand Simberg because of accusations they made that were actionable. Michael Halpern summarized: Competitive Enterprise Institute’s space technology and policy analyst, Rand Simberg, recently wrote a blog post in which he compared Penn State…

How Melty Was The Arctic Sea This Year?

The Arctic Sea is covered with ice during the winter, and some of it melts off every summer. Over recent years the amount of melt has been increasing. This is the time of year we may want to look at Arctic Sea ice because by late September it has reached its annual minimum and is…
