Major Cold Surge To Hit China; Arctic Air Returns To US; Another SSW Builds; Hemisphere Cooling Spike; El Niño Watch; Satellite Surface Data Show No Warming; + Higher CO2 Has Boosted US Crop Yields

This demonstrates how rapidly cooling can develop when the circulation setup allows.

It would be interesting to see Roy Spencer’s anomaly chart for the lower stratosphere. From the data it appears to have slowly cooled over the last 50 years while the troposphere has generally warmed up

  Won’t AI data centers with their huge footprints be causing a rise in CO2? Good for the crops!

The Northern Hemisphere January sea ice anomaly slope for the period 1979-2026 is -2.9 or -0.4% per decade according to NSIDC.
Is this slope really true for the period 2005-2026?
1979-2004= 25 years.
2005-2026= 21 years.
If there is no increasing sea ice loss for half the period, can’t the same slope be used for the entire period?
