Breaking News!
Code: UFB!!!

On October 29, 2026, the 4-year running average for the global surface temperature anomaly hit 1.500°C above the 1850-1900 IPCC pre-industrial baseline (Copernicus data).

Next up: the 5-year running average.

In IPCC land, 1.3°C sounds right.
Multiple datasets, delayed 10 year running average, and then lowballed, for good measure.

Will IPCC AR7 show global warming below 1.5°C?

My attempt to predict this, based on past AR reports, data, and a projected warm end to 2026 and even warmer 2027.

A semi-subjective concept graphic suggesting the IPCC will continue to report 5+ years behind what the world is experiencing.
A graph with four main elements: (1) Annual Global Warming data from world class datasets: Berkeley Earth, Nasa Giss, Copernicus ERA5, UK Met Office HadCRUT. Note this includes "Future Data", where I assume that, for each dataset, 2026 will be the same global warming value as 2024, and 2027 will be 0.15°C warmer than 2024. (2) Trend line, taking the average for each year, and then creating a Loess-30-year-average trend line. This includes the "Future Data" for 2026 and 2027. (3) Graphical Shapes that try to show the Global Warming values reported in the IPCC Assessment Reports. (3A) The IPCC Reports tend to state a range of dates, and a range of global warming values, so I plot the central global warming value as well as the global warming ranges, and the date ranges. I also plot the global warming rate from the IPCC Report, and thereby show what the IPCC implied global warming value would likely be at the time the report was actually published. (3B) For AR2 and AR3, there is no date range supplied, so they just have vertical lines. This may not be fair to the IPCC? (4) Graphical Shape which makes a guess at what values will be published in IPCC AR7 in mid 2028 (if indeed the IPCC end up publishing AR7 in 2028). This graphic is fully explained, with references, data tests and sanity checks on the web page: https://parisagreementtemperatureindex.com/will-ipcc-ar7-show-global-warming-below-1-5c/

One thing that worries me more than anything is that the dire financial situation for the IPCC makes it deeply vulnerable to the contingent of the climate science world that LOVES fossil-fuelled low-quality analyslop and would replace the hard work of the IPCC with a shitty chatbot in a heartbeat.

I recommend this great complimentary article to the one in Propublica with a wider focus and longer time span on IPCC-CCS development written by Fessoz in 2025.

Ironically, most of the countries that want to delay the next IPCC report have contributed nothing to the IPCC financially for years, if ever. 🙄

I was recently asked if we should replace the IPCC with something less flawed. My answer is that nothing else could inspire top scholars worldwide to volunteer years of their lives to produce a definitive source on the state of our climate, impacts, and solutions. We have to fund the IPCC.

You could fund the IPCC for the next half-century with a miniscule fraction of the amount of money that's been poured into absurd, hypey AI/climate start-ups *just this year*

We've got some absurd, messed up priorities at the moment

November 3, 1990 – more smears about the IPCC, in the Financial Times
allouryesterdays.info/2023/11/02/n...
Thirty three years ago, on this day, November 3, 1990, the normally sane Financial Times published a brain fart of an article Thomas, David (1990) The cracks in the greenhouse theory. Financial Times 3 November There were claims that the IPCC organisers had deliberately excluded strong dissenters, such as Richard Lindzen, Hugh Elsaesser and Fred Singer, from participating in the IPCC. One unnamed scientist went so far as to claim that the supporters of the greenhouse theory ‘behave like Hitler’ by conspiring to prevent critics from publishing their conclusions in leading scientific journals (quoted in Thomas, 1990.) Paterson, M (1996) Page 45 The amount of carbon dioxide in the air was roughly 354.4ppm. As of 2023 it is 419ppm, but check here for daily measures. The context was that the IPCC’s first assessment report had been delivered two months earlier. Since then, there had been fierce

IPCC authors meet in Tanzania to advance work on the report on physical science of climate change.

The meeting is hosted by the Government of the United Republic of Tanzania through the Tanzanian Meteorological Authority and runs from 2 to 6 November 2026.

model for the development of other IAMs. The DICE model is definitely not disinformation, though one can -- as I do -- disagree with how Nordhaus used it to provide policy advice. Without DICE and IAMs, much of the social science work of the IPCC and others would be inconceivable. Setting all that

Pero, como siempre y para recordar lo que supone, veamos lo que cada unidad es capaz de ahorrar tanto en combustible, como de emisiones (descontando las producidas por las recargas).

Los VE evitan la compra y quema de un montón de combustible, más, cuanto más profesional es su uso.

When I taught climate change mitigation, the reliance on CCS and especially BECCS (bioenergy with carbon capture and storage) in the IPCC reports always felt "off" to me given my work on ethanol. But I'm not a geologist and I trusted the CC mitigation options the IPCC pushed. What a disappointment.

A U.N. report concluded carbon capture could offset fossil fuels’ effect on climate change. Two decades later, the process has failed to meaningfully scale up, and it’s proving hard to take the promis...
