New version of the HadCRUT global temperature dataset released @colinmorice.bsky.social HadCRUT5.2 uses HadSST4.2 (with improved adjustments for SST biases during 1933-1961) and CRUTEM5.2 (with updates to stations in China, USA and Canada). Here is the difference from the previous version 5.1

The Montreal Protocol was signed on this date in 1987. The greatest environmental treaty in history. With the current intense polar vortex, 25 years ago we would be observing one of the largest ozone holes on record. Today, a sizable ozone hole, and a sign of slow healing. ozonewatch.gsfc.nasa.gov

Thursday El Niño update - Ocean temperatures have again ticked upwards in the key Niño 3.4 region. There continues to be growing confidence from nearly all types of forecasting systems in a historic event over the next couple of months. Though it doesn't always mean bigger impacts Data: OISSTv2.1 🌊
Line graph time series of daily sea surface temperature anomalies in the Nino3.4 region. Years are shown from 1982 to 2025 in shades of blue to light yellow, and 2026 is shown in red. Climatologically, the largest anomalies are during the boreal winter in terms of magnitude. Data is from OISSTv2.1.

It's striking how similar are the patterns of the highest and lowest temperature anomalies in the northern hemisphere in June 1976 and June 2026 and also how much warmer 2026 is overall. Not an original idea, but unusually clear example of how a similar weather pattern is much warmer now than then.
