Greenhouse gases endanger human health and welfare

Today we won. A U.S. District Court ruled that the administration violated federal law when it secretly convened a group of climate contrarians to produce a thoroughly debunked report to overturn the Endangerment Finding. The science still matters. We won't stop. www.nytimes.com/2026/01/30/c...

It’s a graph. But it’s also people. Real people who dedicated years of their lives to making the world a better place. Our colleagues, our neighbors, our friends.

I just posted the second in my Endangerment substack series: thesaraphreport.substack.com/p/did-epa-ge...

A must follow!

My colleague @bobkopp.net has a nice thread rundown of the many problems and illegal actions of the Dept of Energy Climate Working Group report based on the emails that came out yesterday from @envdefensefund.bsky.social lawsuit: www.edf.org/media/newly-... I would just add a few things re NCA5 1/

Join us this Thursday as NOAA demos three new and improved environmental data products being co-developed with the #insurance and #reinsurance sector that help users assess risk, improve critical decision-making, and build resilience! You can register here: lnkd.in/et2CyxAN

Looking forward to moderating a great discussion on how the retail, insurance/ reinsurance, and architecture and engineering industries are using NOAA's weather and climate data to guide decision-making and build resilience. Hope you can join us! #AGU25 agu.confex.com/agu/agu25/me...

🚨 JUST PUBLISHED 🚨 ⚠️ The 2025 @lancetcountdown.bsky.social report reveals climate change inaction is costing lives and livelihoods, and harming the economy. ❤️‍🩹 Protecting people’s health demands all hands on deck. Read more: www.lancetcountdown.org/2025-report/ #LancetClimate25

Today, the U.S. faces one billion+ dollar climate/weather disaster on average every 2w. That's a massive increase from one every 4m in the 1980s. This is 'global weirding' and people are taking notice! The government told NOAA to stop tracking these events: but @climatecentral.org is on the job.

New paper from @marcusmarcusrc.bsky.social and team on the impacts of future climate trends on tropical cyclone–induced power outages. Spoiler: disproportionate risks for Hispanic, non-White, and low-income populations and huge increase in annual costs of outages. www.pnas.org/doi/10.1073/...

📢 Submissions are now open for the U.S. Climate Collection, a joint @theAGU + @ametsoc initiative. This special collection will publish U.S.-focused climate assessment science that’s free to read, ensuring rigorous, accessible science informs decisions for years to come. 🔗 buff.ly/1tHUSLC

Thank you

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨 Please RT this so as many people see it as possible. forms.gle/BL9xUAfRxA...

Oh you’re taking public comments?

Today is #ShowYourStripes Day 🔵🔴 A single image. A century of data. Every city, state, county -- the planet -- has an impact of climate change story — and the stripes show it. Post yours. Highlight the warming where you live. Start the conversation.

Looking forward to hearing more tonight! peoplesbooktakoma.com/event/human-...

In NYC June 16? You’re invited to my book launch!!! It’s at the beautiful New York Public Library and it’s free and I can’t wait to see you there www.nypl.org/events/progr...

Most Americans frequently use federal science information. But few are concerned that cuts to federal science spending could affect their access to such information, a new poll finds.

Last week, the govt dismissed 400 researchers working on the US National Climate Assessment. I was one of them. Today, @agu.org & @ametsoc.org announced they are joining forces to sustain the momentum. It's not a replacement, it's a reminder that science is unstoppable. news.agu.org/press-releas...

Working on the NCA5 was amazing. It was genuinely moving to be surrounded by so much dedication and sheer scientific and administrative *excellence*. I think we’ve forgotten how to believe in good things, but this was one of them.

And yet it moves

Very excited to see the release of the 2nd Status of Tribes and Climate Change (STACC) Report! Congratulations to ITEP and all the authors, artists, and contributors for this massive undertaking and critical work! www.nau.edu/staccreport

US climate researchers and practitioners interested in contributing to the @ipcc.bsky.social Seventh Assessment Report - apply by April 4! www.agu.org/ipcc-nominat...

This week, the first two papers in a special issue of Climatic Change were published. The issue features advancements and lessons learned from #NCA5 and other state, regional, and national assessments, including process, content, and communication innovations. link.springer.com/collections/...

Come for me laying down some facts. And stay for the legos in the background.

This is such a horrible loss for NOAA and all of us. I’m so sorry Tom.

Great article from @climate.noaa.gov on the California wildfires looking at climate change and natural influences.

This is an existential moment for federal scientists and other public servants as they face pressures to resign. We must do everything we can to safeguard the federal science enterprise. Thoughts and recommendations from me out in @nature.com today: www.nature.com/articles/d41...

Climate change affects us all. Scientist @bhamlington.bsky.social talks with @lsommer.bsky.social about his family’s experience ⬇️

Heads up for the Weather Community! You can now find NOAA (@noaa.gov), NOAA Climate (@climate.noaa.gov) & NWS HQ (@nws.noaa.gov; still being set up) on Bluesky!

Well hello and welcome climate.noaa.gov !

Shout out to Federal workers in this moment. To those who chose to use their time and talents to put the nation on the best trajectory towards a clean energy future, a more just society, and a safer environment. To those who took a leap of faith and went into Federal service at this critical moment.

Thinking about all my Moss Landing and Elkhorn Slough peeps and hoping you’re safe

The data is in. 2024 was the warmest year on record, and probably in the whole of human history – about 1.6°C warmer than the pre-industrial period. More than 1 billion individual thermometer measurements, made by thousands of people over many decades, have been condensed into a single number.

All surface temperature products for 2024 are now live. All show 2024 is the warmest year (very clearly). The estimates of the change since the pre-industrial (1850-1900) are more uncertain but range from 1.46 to 1.62ºC. It is therefore *likely* this was the first year that exceeded 1.5ºC.

The NOAA/NCEI numbers are in for the United States. 2024 was the warmest year on record, as well as a top third wet year. Here is the updated #ClimateStripes to reflect the years 1895-2024 #StateOfClimate @edhawkins.org

It's been 100 days. Helene will be the most damaging inland flooding in US history. We had many distractions since, but the wound is still open. Your help, your taxes, your love, all helped this region cope. But there's a long way to go. Please consider the southern Appalachians. Thank you. 1/n

New starter pack! Climate change and fossil fuels affect our health in a myriad of ways. That's why solutions for clean energy, nature, and climate resilience can also be solutions for better health. These experts + organizations are helping us make those connections ⬇️ Who'd I miss?

ICYMI: FRN for an RFI from OSTP/ USGCRP on downscaled data for NCA6. Acronyms FTW! ;) Request for Information to identify downscaled datasets that may be used by 6th National Climate Assessment #NCA6 and to develop an updated data atlas. @usgcrp.bsky.social www.federalregister.gov/documents/20...

I’m really really looking forward to this!!!

If you're an author or technical contributor on the 6th U.S. National Climate Assessment and would like to be included in this starter pack, reply with your chapter or DM me. I'm very grateful to be part of this. go.bsky.app/EZeELH7

One year ago, the 5th National Climate Assessment was released! Below is a thread highlighting resources in and around the assessment that you might find useful. nca2023.globalchange.gov

Plenty of good #Climate and Climate adjacent #StarterPacks but how about a good 🧵that makes them all super easy to find and follow? I'm glad I asked. Here you go! #ClimateChange #Renewables #EnergyTransition #CleanEnergy #Advocacy #Activism bsky.app/starter-pack...
