Global Cooling Coming? Archibald uses solar and surface data to predict 4.9°C fall (!)

A fact-based alternative to the British Met Office model-run

David Archibald, polymath, makes a bold prediction that temperatures are about to dive sharply (in the decadal sense). He took the forgotten correlation that as solar cycles lengthen and weaken, the world gets cooler. He refined it into a predictive tool, tested it and published in 2007. His paper has been expanded on recently by Prof Solheim in Norway, who predicts a 1.5°C drop in Central Norway over the next ten years.

Our knowledge of they solar dynamo is improving, and David adds the predicted solar activity ’til 2040 to the analysis. Normal solar cycles are 11 years long, but the current one (cycle 24) is shaping up to be 17 years (unusually long), and using historical data from the US, David predicts a 2.1°C decline over Solar Cycle 24 followed by a further 2.8°C over Solar Cycle 25. That adds up to a whopping 4.9°C fall in temperate latitudes over the next 20 years. We can only hope he’s wrong. As David says ” The center of the Corn Belt, now in Iowa, will move south to Kansas.”

He also predicts continuing drought in Africa for another 14 years, with droughts likely in South America too.

If he’s right, it’s awful and excellent at the same time. Cold hurts, but wouldn’t it be something if we understood our climate well enough to plan ahead?
