We're halfway between the IPCC 6th and 7th Assessment Reports, and an international team of 61 scientists updated some of the key metrics used in the reports. As I wrote for @climateconnections.bsky.social, the findings were pretty bleak, but there are some glimmers of hope 🧵 (1/6)

CCL supports the Fix Our Forests Act to improve forest management practices and reduce wildfire risk. This legislation also provides support for firefighters on the front lines.

Optimism and pessimism. The IEA renewables 2025 update is fascinating. It ratchets down both US and China's renewable buildout from the 2024 report. US down more than 40% (!) and China down about 5%.
Forecast revisions from IEA Renewables 2025 report.

September 2025 was the third warmest September on record at 1.47C above preindustrial levels in ERA5, behind only the prior two years (2023 and 2024).

With 9 months of the year now in, I estimate 2025 will approximately tie with 2023 for the second warmest year on record at ~1.48C.

If the U.S. government shuts down on Wednesday, hundreds of thousands of workers will be sent home without pay, disrupting a wide range of federal programs. But not all agencies have released contingency plans for how they would operate. Here’s what we know. nyti.ms/4nncpwq

This is amazing: @ladwp.com, the Los Angeles utility, has launched a program that will install solar+battery systems on qualifying low-to-moderate-income households, *for free*.

Yes: free.

If you know someone eligible, tell them to apply!
Self-Generation Incentive Program
The Self-Generation Incentive Program (SGIP) helps qualified LADWP residential customers install solar and battery storage systems by providing financial incentives. This program supports clean energy...

Really proud of our team at Project Drawdown.

We just launched the biggest thing we’ve ever done — by far.

A billion times more data than anyone has ever collected before, providing localized intelligence on 150+ climate solutions.

For free.

Project Drawdown has always been the world’s leading guide to science-based climate solutions 🌏.

With the new Drawdown Explorer, we’re moving beyond describing solutions → to spotlighting breakthrough strategies for accelerating climate action.

COUNTRY ANALYSIS: We have downgraded the #US climate action to "Critically insufficient" - it's the most aggressive, comprehensive and consequential climate policy rollback the CAT has ever analysed.

I have a new @nytimes.com guest essay w/ @davidkeith.bsky.social about sunlight reflection. We note its not a solution for climate change and at best a band aid to treat systems, and suggest if its ever done it should only be to replace the cooling from air pollution today:
Opinion | A Responsible Way to Cool the Planet
A small, carefully scaled geoengineering program could compensate for the loss of cooling as we eliminate sulfur pollution.

Microsoft gave guidance on H1Bs to its employees last night

i don’t think people on bluesky understand the severity of this situation.

i woke up to literally hundreds of texts from friends and family thinking about either moving back home to india or applying to other countries for jobs. this includes me.

Those on an H1B cannot return to the US from tomorrow (Sunday) unless paying $100K. This is an out-of-the blue presidential action. We’ll see software engineers stranded abroad.

One easy to predict outcome: those on US visas will travel less… for work, for conferences etc.

The authors conclude, “This is also the decade when global [greenhouse gas] emissions could be expected to peak and begin to substantially decline. Depending on the societal choices made in this critical decade, a continued series of these annual updates could track an improving trend.” (6/6)
Climate change is accelerating, scientists find in ‘grim’ report » Yale Climate Connections
They warn that humanity is just three years from overshooting the Paris Agreement’s 1.5°C target, with seas rising faster than ever. But the report also contains a little bit of good news.

A small silver lining is that at current emissions rates, the 2°C carbon budget won't be breached until around midcentury, which leaves several decades to bring emissions down. Co-author @hausfath.bsky.social noted, "global CO2 emissions have slowed notably over the past 15 years or so" (5/6)

That accelerated warming is causing accelerated sea level rise, now at 4.5 mm/yr, up from 3.7 mm/yr since 2000, which itself is double the 1.85 mm/yr rate since 1900. Lead author Piers Forster noted these unprecedented rates are "expected from greenhouse emissions being at an all-time high" (4/6)

The paper finds that we're on track to burn through the 1.5°C carbon budget within 3 years, and breach that long-term temperature marker by around 2030. We're now 1.24°C hotter than pre-industrial temperatures, rising at about 0.27°C per decade. That's nearly 50% faster than the '90s & '00s (3/6)

Earth’s energy imbalance, driven by the increasing greenhouse effect, is the cause of global warming. And it's been consistently rising every decade. In fact, the global imbalance has more than doubled just since the 1980s. And we're still adding ~50 billion tons of climate pollution annually (2/6)
