Climate Change

The year that just finished, 2015, was the warmest year recorded in the instrumental record. The actual data for December is not officially available yet, but my friend and colleague John Abraham keeps track of the global surface temperature daily and has done an amazing job at estimating the final temperature anomaly value that is…

Despite the devastating storms across the country the last few weeks, NASA is forecasting the worst is yet to come. Michael Mann, author of “Dire Predictions: Understanding Climate Change” joins to discuss.

This is a guest post by Larry Lazar. If you have had the news on the last day or two you may have seen stories and images about the Missouri floods. Many of those images are from Eureka (where we live), Pacific (where my wife Kellie works) and Valley Park (which is on my commute…

This is a long story that I’ll try to make short, because I’m trying to make a single, simple point. Years ago shock jock and right-wing political commenter Mark Steyn, using the vehicle of the conservative magazine National Review, made disparaging remarks about climate scientist Michael Mann. These remarks were viewed by Mann and others…

In November, I wrote a post describing research on Antarctic glacial melting by Catherine Ritz, Tamsin Edwards, Gaël Durand, Antony Payne, Vincent Peyaud, and Richard Hindmarsh (“Potential sea-level rise from Antarctic ice-sheet instability constrained by observations”). I had asked one of the authors, Tamsin Edwards, to address a few questions about the study. I also…

Global Warming In November

The NASA GISS global temperature anomaly for November has been published. October’s value was originally reported as 104, but has been corrected (it is normal to have small corrections on an ongoing basis) to 106. November’s value, just out, is 105. This is hundreds of a degree C anomaly, the standard number used to report,…

This post was written by Peter Sinclair and Greg Laden in response to a recent Wall Street Journal Op Ed piece by Matt Ridley and Benny Peiser. In a recent Wall Street Journal commentary, “Your Complete Guide to the Climate Debate,” Matt Ridley and Benny Peiser ask what might make world leaders concerned about the…

Global Warming Did Not Pause

You’ve heard much about the so-called “pause” or “hiatus” in global warming. One of the implications of a multi-year “pause” in global warming is that the science of global warming must be somehow wrong, because with CO2 rising in atmosphere, due to human activity, how can the surface not warm? However, surface temperatures have been…

A few days ago a team of climate scientists (Catherine Ritz, Tamsin Edwards, Gaël Durand, Antony Payne, Vincent Peyaud, and Richard Hindmarsh) published a study of “Potential sea-level rise from Antarctic ice-sheet instability constrained by observations.” The study asked how much Antarctic ice sheets might contribute to global sea level by 2100 and 2200 AD.…

Record daily high and low temperatures happen now and then at a give weather station. In a normal, stable climate the number of record highs and record lows should be about even. But with human-caused global warming, record highs are expected to be more common than record lows. And they are. Climate Nexus has this…
