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…

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 important for two reasons. One is because of what it says about how to interpret the available data on…

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…

March 2015 Was A Very Warm Month

The last 12 months have been the warmest one year period in the NASA database since records began in 1880. According to the just released NASA GISS Global Temperature Data, March, 2015 is estimated to have been the fifth warmest month on record. Here are the top 20 months in rank order: 2007 JAN 93…

The rise of Skeptical Science

The site, not the thing. From the YouTube site: Everyone at Skeptical Science spends a lot of their time reading the scientific literature and listening to experts. Without that we wouldn’t be able to write all the material that’s published on Skeptical Science. It’s a lot of work, especially when you do this with a…

Maybe, maybe not. There is a new paper that looks at what climate scientists call “synoptic midlatitude temperature variability” and the rest of us call “cold snaps” and “heat waves.” The term “synoptic” simply means over a reasonably large area like you might expect a cold snap or heat wave to be. Specifically, the paper…

A new study by Sarah Moffitt, Tessa Hill, Peter Roopnarine, and James Kennett (Response of seafloor ecosystems to abrubt global climate change) gets a handle on the effects of relatively rapid warming and associated Oxygen loss in the sea on invertebrate communities. The study looked at a recent warming event (the end of the last…
