Two opinion pieces (, and ) and a supportive were published this week, extolling the prospects for what they call "k-scale" climate modeling. These are models that would have grid boxes around 1 to 2 km in the horizontal - some 50 times smaller than what was used in the CMIP6 models. This would be an enormous technical challenge and, while it undoubtedly would propel the science forward, the … Read Full Article about Mmm-k scale climate models

Digital Twinge
A couple of weeks ago the EU announced that they were funding a project called DestinE (Destination Earth) to build 'digital twins' of the Earth System to support policy making and rapid reaction to weather and climate events. While the term 'digitial twin' has a long history in the engineering world, it's only recently been applied to Earth System Modeling, and is intended (I surmise, as does … Read Full Article about Digital Twinge

River Ice break-up trends 2022
As in previous years, the spring break-up of river ice on the Tanana River at Nenana and the Yukon River at Dawson City in Canada (new! h/t Ed Wiebe), is a great opportunity to highlight phenology that indicates that the planet is in fact reacting to the ongoing global warming. As we've done in … Read Full Article about River Ice break-up trends 2022
The modern demarcation problem
Defining (and enforcing) a clear line between information and mis-information is impossible, but that doesn't mean misinformation doesn't exist or that there is nothing to be done to combat it. I found myself caught in an 'interesting' set of exchanges on twitter a few weeks ago (I won't link to … Read Full Article about The modern demarcation problem
Issues and Errors in a new Scafetta paper
Earlier this week, a new paper appeared in GRL by Nicola Scafetta which purported to conclude that the CMIP6 models with medium or high climate sensitivity (higher than 3ºC) were not consistent with recent historical temperature changes. Since there have been a number of papers already on this … Read Full Article about Issues and Errors in a new Scafetta paper
The Future of Climate Modeling?
There was an interesting workshop last week focused on the Future of Climate Modelling. It was run by the World Climate Research Program (WCRP) Core Project on Earth System Modelling and Observations (ESMO) which is part of a bewildering alphabet soup of various advisory committees that exist for … Read Full Article about The Future of Climate Modeling?

Future rainfall over Sahel and Sahara
Ethiopia is praying for rain according to a recent report from the Guardian, and ReliefWeb suggests that a lack of rain may be linked to malnutrition in Tchad, as well as reduced crops in Niger. The African rainfall deficit appears to be widespread: the Cairo Review reports severe droughts … Read Full Article about Future rainfall over Sahel and Sahara
