Long-form interview with Jon Watts in the Guardian about El Niño and climate change. Including the new concept of the ocean ‘vomiting’ heat into the atmosphere. What is El Niño, what causes it and can we reduce the risks? www.theguardian.com/environment/...

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

August 2026 was the warmest August ever recorded globally and the warmest month on record El Niño is pushing temperatures higher, but these records are occurring in a climate that has already been fundamentally altered by decades of burning fossil fuels heating our planet #Climate 🧪⚒️🌊

Left: "traditional" Niño 3.4 SST anomalies since 1 January - much larger than in any other year. Right: "relative Niño index", made by subtracting the mean tropical SST anomaly shows that 2026 is similar to 1997. The coming record temperatures are thus due to global warming. Source: cyclonicwx.com.
"Traditional" Niño 3.4 index (SST anomalies for 5°N-5°S, 120°W-170°W) for selected years. 2026 is clearly warmest."Relative Niño index" for the same region and years. Relative Niño indices are created by taking the mean SST anomaly in the region, subtracting the mean SST anomaly of the 20°N-20°S tropical band, and multiplying by a scaling factor derived from observed SSTs to ensure the resulting value has a similar amplitude to the corresponding traditional Niño index. This index therefore shows the relative El Niño strength without the increased background temperature due to global warming.

In accordance with ancient tradition, our next Prime Minister is announced to the nation while standing between a furry and a man with a bin on his head.
A victorious Andy Burnham MP (24,937 votes), as the result of the Makerfield by-election is announced, flanked by defeated candidates Count Binface (a bloke in a vaguely sci-fi costume with a large bin for a helmet; 95 votes) and Robert Pownall (who is in a full body fox costume, holding a sign reading "Protect British Wildlife"; 18 votes). There are some other candidates there just out of shot but that's not important right now.
