Preliminary global average CO2 concentrations in for 2025 (NOAA) 425.79 ppm This us up from 422.90 ppm in 2024 = +2.89 ppm (preliminary) We will therefore keep heating and keep experiencing climate chaos. The last 3 years (ERA5 data) global temperatures have averaged ~1.52ºC above preindustrial

An intense heatwave (~40°C) causes electricity demand to surge and crashes grid in Buenos Aires Urgent adaptation is needed to prevent grids from collapsing during heatwaves. This is all happening with background heating at ~1.5°C We are firmly on track to pass 2°C

As we move into the era of physical environmental instability (floods; droughts; heatwaves; etc) businesses that are able to function efficiently from anywhere (ie embrace remote work) will experience *way* less disruption than those insisting on being in person at a specific location.

2025 is in the climate books. 3rd warmest after 2023 and 2024 or tied 2nd warmest after 2024 (preliminary). The trend continues to be up, even tho it is within the expected range of warming given the known external factors. Below the HadCRUT5 dataset ... www.metoffice.gov.uk/hadobs/hadcr... (1/2)

Current instrument readings: ~1.47ºC current 12-month running mean (ERA5) ~0.31ºC/decade current heating rate 425.78 CO2 ppm (2025 year-to-date) Global CO2 emissions from fossil use are projected to rise 1.1% in 2025 Given current government commitments there is a 75% chance we will cross 2ºC

The three graphs that explain the escalating #ClimateCrisis “To date, no [governments] have set targets to reduce oil and gas production or phase out inefficient fossil fuel subsidies”—UNEP 2025 As a result we are 75% certain to cross 2°C of heating. We are on a highway to hell.

Among Western democracies, the US is basically in a league of its own. No other comparable democracy has climate denial so deeply embedded in a major political party, its media ecosystem, and parts of government. It remains the largest contributor to the 425.78 ppm CO2 currently in the atmosphere.

"I find it stunning that some people in the climate community say that we should stop talking about climate because there’s a cost-of-living crisis going on. It’s a fundamental error to treat these issues as mutually exclusive climate solutions are cost-of-living solutions."

2024 was the hottest year in modern history. There has never been a better—or more urgent—time for journalists to report on the actions, promises, & misconduct of the industry driving climate change. So today, @gijn.org published the first of our seven-part Guide to Investigating Fossil Fuels.

💯 agree with this recommendation whether you are inside or outside the US. Watch this NOW! There is at least 3 more years of this ahead if not more. Be informed. Reference is made to the Anti-Autocracy Handbook see zenodo.org/records/1569... Read it!

It took literally more than a year but a few months ago I was finally able to convince my editor that we should stop posting on X. He was worried there would be an outcry if we stoped. There wasn’t. No one noticed because, thanks to the algorithm, no one was seeing our stuff there anymore anyway.

I've put together my predictions for 2026 and 2027 temperatures over at The Climate Brink. I expect 2026 will likely end up similar to 2023 and 2025 at ~1.4C, while 2027 will likely be considerably warmer (conditional on El Nino): www.theclimatebrink....

When an extreme event hits a place that has no built resilience, that place, is more often than not taken below a tipping point from which complete recovery is not possible. This leads to permanent loss. We see this playing out everywhere. news.un.org/en/story... #ClimateCrisis

When you bet on the past you lose. China solidifying its position as the world’s first electrostate. I am sure they cannot believe their good fortune.

For every 1°C that we heat the atmosphere can hold approximately 7% more water. Extreme precipitation willl become more frequent putting people living near seasonal rivers at great risk. We need robust early warning systems for people living near rivers! youtu.be/93K0ZyfTUPs #ClimateLiteracy

More from the coalition of planet destroyers: “After the objections of the U.S. official, as well as some from Saudi Arabia, Iran, Russia and other oil and gas producing nations, the summary for policymakers language was dropped entirely rather than renegotiated.”

As I have said before don't look away from this! There is *every* indication that events such as this will become more frequent and severe as we continue to heat. What we are witnessing here has taken place with background heating of ~1.5ºC We are firmly on track - 75% certain - to crossing 2ºC

100% this: “If we want an internet where publishers retain autonomy and readers retain agency, we need to treat RSS not as legacy plumbing but as strategic infrastructure.”

Never forget, car dependency isn’t freedom. Some might ask “what’s more free than cars?” Choices. Choices are more free than car dependency. It’s not a hard concept. I’m not pitting cars against any other single mode of transport. I’m rejecting design that creates dependency on just one mode.

The latest #climate update from Copernicus shows that 2025 is on course to be: - joint 2nd warmest year, tied with 2023 and behind 2024 (warmest year) - November 2025 was the 3rd warmest November globally For more: climate.copernicus.eu/copernicus-2... 🌏🌡️⚒️🧪🌊

2025 is on course to be joint-second warmest year. The #C3S Climate Bulletin reports that November was 1.54°C above pre-industrial levels, making it the third-warmest November on record. The 2023–2025 average is likely to be the first three-year average exceeding 1.5°C. Find more info ⬇️

It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.
