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.

Wednesday El Niño update - Some notable warming across a large part of the eastern half of the tropical Pacific Ocean during the last 7 days. And an ongoing strong westerly wind burst will continue to strengthen El Niño even further toward record territory. Data from NOAA 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. Map of July 27, 2026 average sea surface temperature anomalies in the ENSO monitoring regions. Data is from NOAA OISSTv2.1 with anomalies relative to a 1991-2020 baseline.Graphic showing the 1-week change in sea surface temperature anomalies across the tropical eastern Pacific Ocean from July 20, 2026 to July 27, 2026. Data is from NOAA OISSTv2.1

A week late but excited to share @nationalacademies.org report on Attribution of Extreme Events and their Impacts. Had the opportunity to work with amazing colleagues to reflect on the incredible progress in EEA and review the breadth of applications @climate-done.bsky.social @jmarlon.bsky.social

Attribution of Extreme Weather and Climate Events and Their Impacts

Decades of data and research indicate that human-caused climate change is altering the frequency and intensity of several types of extreme events, such as heat waves and extreme rainfall events. Even...

'The lords know the problems because everybody can see the problems. Some peers are particularly astute at calculating the damage being done. Yet there was an air to this debate of a bunch of clever people discussing climate change in an air-conditioned room while it is 38 degrees outside.' 1/2

The House of Lords fiddled while Exeter burns

At last week’s HE debate, a host of Oxford-associated grandees made the usual points while the sector continued to melt down, says Andrew McRae

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. Photo: Jon Super/AP
