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

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 it to spare you the tedium, but you could probably find it if you look hard enough).

As we've done in … Read Full Article about River Ice break-up trends 2022
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?
The end of blog comments?
Over the last decade, commenting has dramatically moved from specific web-sites to general social media platforms, radically changing how people interact with longer-form content (such as blogs, substacks, newspapers and journalism).

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
Another dot on the graphs (Part II)
We have now updated the model-observations comparison page for the 2021 SAT and MSU TMT datasets. Mostly this is just 'another dot on the graphs' but we have made a couple of updates of note. First, we have updated the observational products to their latest versions (i.e. HadCRUT5, NOAA-STAR 4.1 … Read Full Article about Another dot on the graphs (Part II)
