Note: The original title of this post was “A Global Warming Fingerprint Confirmed: Upper Troposphere Warming” because I was thinking that upper troposphere warming was a fingerprint. John Cook contacted me to let me know that he didn’t think it was. The reason it is not is that more than one thing can cause upper…

Bjorn Lomborg has written an Op Ed in the Wall Street Journal lamenting the decision of the University of Western Australia (UWA) to nix previously developed plans to accept a $4 million dollar payment from the conservative Australian government, to be matched by university money, to implement a version of Lomborg’s Copenhagen Institute there, to…

Global warming is typically measured at the surface, with data from thermometers all across the land areas and sea surface temperatures combined. That isn’t the whole story, of course. Much of the added heat, an effect of human generated greenhouse gas pollution, goes into the upper 2,000 meters or so of the ocean. But we…

Over the last several weeks we’ve seen the University of Western Australia accept a $4 million dollar Federal grant to develop a “Consensus Centre” in the mold of Bjorn Lomborg’s non profit, with Lomborg as a key player. Lomborg has been heavily criticized for his lack of scholarship and seemingly biased policy related to climate…

The #FauxPause is Faux

The Earth’s climate is warming. The upper oceans are warming, the sea surface temperatures are elevated, the air in the lower Troposphere, where we live, is warming. This warming is caused almost entirely by the increase in human generated greenhouse gasses and the positive (not positive in a good way) feedbacks caused by that. The…

I’m auditing the EdEx course “Denial101x: Making Sense of Climate Science Denial.” This is Week 2: Global Warming ins Happening. The course is covering indicators of warming, what is happening in the Cryosphere, and related matters. Here is an example lecture segment: A central theme of this week is the relationship between climate and weather,…

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’s 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…
