Still kind of reeling from this… 😳

If you want to know more about how we established that there is a statistically significant increase in the speed of global warming since 2015, @CarbonBrief explains it nicely.

For such a softly spoken guy, Ben doesn't hold back on the Trump administration: "Insane. That’s the only word for it. Removing our ability to measure and monitor how the world around us is changing, makes no sense whatsoever."

Here's our annual look at the most talked-about climate papers of the previous year:

Are you a journalist covering COP30 looking for new and diverse sources? Check out the Global South Climate Database. This publicly available, searchable database features 1000+ climate scientists and experts from the global south. 🌍🔗 buff.ly/5bhfWeV

Here's our annual look at COP delegates: Top story: no US delegation for the 1st time in COP history Also: ~56k people registered, so no big drop-off despite accommodation issues in Belém (Caveat: these are provisional figures) Also also: most "virtual" delegates ever #COP30

In a UN speech today, President Trump said that "all of these [climate] predictions were wrong". Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

Well this is embarrassing for "newspaper of record" The Times: Its coverage of EVs is the most misleading among UK titles, with 52% of pieces in H1 2024 containing at least one misleading statement (The Daily Telegraph "wins" on volume, with 44 misleading pieces) 1/4

The recent DOE climate science report misrepresents the work of many researchers. Carbon Brief asked those cited to review the parts of the report where their work was used, and we collectively found 100+ misleading or false statements: interactive.carbonbrief.org/doe-factcheck/…

And then @thetimes, revealing its credulity, has followed with its own piece that does exactly the same thing (just 2 hours later): thetimes.com/uk/environment…

Here's more on the “Packaging extended producer responsibility” scheme: commonslibrary.parliament.uk/research-brief… I suspect the Telegraph knows that the connection to net-zero is bogus as it only mentions the phrase in its headline & opening line. Link here: telegraph.co.uk/news/2025/06/2…

More net-zero misinformation in the @Telegraph It claims that a proposed scheme to put the cost of recycling onto packaging producers, rather than local councils, is a “net-zero glass tax”. It is about waste management, not net-zero. Somehow, this made it onto the frontpage 🤦

2025 had the second warmest first quarter (Jan-Mar) on record, just a hair behind last year (2024). This is remarkable since 2024 was boosted by a strong El Nino event, while 2025 started off in weak La Nina conditions.

My HORRIFYING cartoon for this week’s @GuardianBooks

On today's and yesterday's @BBCr4today programme, it was erroneously suggested that car companies, like Tesla, receive Government subsidies via the ZEV Mandate This is completely false Not a penny of taxpayer money is given to car manufacturers via the Mandate A short thread

Dear @BBCNews - none of these answers are correct. bbc.co.uk/news/articles/…
