Global Warming: Getting worse

I recently noted that there are reasons to think that the effects of human caused climate change are coming on faster than previously expected. Since I wrote that (in late January) even more evidence has come along, so I thought it was time for an update. First a bit of perspective. Scientists have known for…

Dire Predictions: Understanding Global Warming by Michael Mann and Lee Kump is everyperson‚Äôs guide to the latest Intergovernmental Panel on Climate Change (IPCC) report. The IPCC issues a periodic set of reports on the state of global climate change, and has been doing so for almost two decades. It is a massive undertaking and few…

I recently posted an overview of a new climate study, Comparing the model-simulated global warming signal to observations using empirical estimates of unforced noise, by Patrick T. Brown, Wenhong Li, Eugene C. Cordero & Steven A. Mauget. That study is potentially important because of what it says about how to interpret the available data on…

What is scientific consensus?

A group of scientists attending a major conference get together in a bar. They talk, but they agree on nothing because they are critical academics. The server comes along to take the beer order and says, “I noticed you all are constantly arguing. What are you arguing about?” “Sensitivity,” one of them says. “It is…

Will 2015 be warmer than 2014?

That is a good question, and difficult to answer. If it turns out to be, it will be the warmest calendar year in the instrumental record, which goes back into the 19th century. Regardless of what El Nino (ENSO) does, 2015 will be a warm year. Why? Because everything is warm and getting warmer and…

This is Part I of a two part treatment of new research on climate change. Part II is here. There is a new paper out, Comparing the model-simulated global warming signal to observations using empirical estimates of unforced noise, by Patrick T. Brown, Wenhong Li, Eugene C. Cordero & Steven A. Mauget. It is potentially…

How To Demolish Climate Denial

John Cook, of the University of Queensland, and his colleagues, have created a MOOC … Massive Open Online Course … called “Making Sense of Climate Science Denial.” Why does this matter? How does it work? What can you do? All of these questions are answered here: University offering free online course to demolish climate denial.…

The American Biology Teacher has hosted a guest editorial by Glenn Branch and Minda Berbeco of the NCSE. The editorial points out that climate science is under a similar sort of anti-science attack as evolution has been for years, though generally with different (less religious) motivations. Also noted is the problem of fitting climate change…

A new study seems to provide a better way to categorize El Nino climate events, and offers an explanation for how different kinds of El Nino events emerge. El Nino is part of a large scale, very important climate phenomenon in the Pacific Ocean, generally referred to as the El Nino Southern Oscillation (ENSO). Over…

There was a time when I picked which local TV news station to watch based on the way the TV meteorologist addressed global warming. There were two stations in the running. One of them had a guy who frequently disparaged climate science, and the other had Paul Douglas, who no longer does TV meteorology (I…
