The first somewhat comprehensive reviews of the DOE critical review are now coming online.

The Endangerment of the Endangerment Finding?
The EPA, along with the “Climate Working Group” (CWG) of usual suspects (plus Judith Curry and Ross McKitrick) at DOE, have just put out a document for public comment their attempt to rescind the 2009 Endangerment Finding for greenhouse gas emissions.

Some intriguing new measurements of salinity in the oceans around Antarctica have set off reams of sensationalist speculations. Maybe some context is helpful…

Over multiple generations of CMIP models Arctic sea ice trend predictions have gone from much too stable to about right. Why?

The WMO released its (now) annual state of the climate report this week. As well as the (now) standard set of graphs related to increasing greenhouse gas concentrations, rising temperatures, reducing glacier mass, etc., Zeke Hausfather and I wrote up a short synthesis on the contributions to recent temperature anomalies.

Climate change in Africa
While there have been some recent set-backs within science and climate research and disturbing news about NOAA, there is also continuing efforts on responding to climate change. During my travels to Mozambique and Ghana, I could sense a real appreciation for knowledge, and an eagerness to learn how to calculate risks connected to climate change.

One more dot on the graphs for our annual model-observations comparisons updates. Given how extraordinary the last two years have been, there are a few highlights to note.

Rapid progress in the use of machine learning for weather and climate models is evident almost everywhere, but can we distinguish between real advances and vaporware?

There is a need to make climate science more agile and more responsive, and that means moving (some of it) from research to operations.

The title of this post might seem like a truism, but for about a decade some people have claimed the opposite, and many people have spent much time and effort trying to understand why. Much of that effort was wasted.
