CO2 concentrations haven’t been this high in at least 3 MILLION years. The Earth’s temperature hasn’t yet caught up. We need to quickly and dramatically reduce CO2 emissions, but last year’s were the highest ever.

"Study finds planetary waves linked to wild summer weather have tripled since 1950" | Great piece by @borenbears.bsky.social for @apnews.com on our new @pnas.org article (w/ thoughtful comments from @jfrancisclimate.bsky.social): vancouver.citynews.ca/2025/06/16/s...

HAPPY 75th, NSF! We’re celebrating this milestone by highlighting some of NSF’s most transformative accomplishments—innovations that have shaped our world and continue to drive progress in health, technology, the environment, and beyond. Read on 🧵(1/11):

I just really need everybody to understand that everything that’s happening in and to the global economy now (and all the businesses and people in it) is the entirely predictable result of the intentional decisions of one guy who doesn’t understand how the global economy works.

Truly striking how the Northern Hemisphere dominates this signal. Even locations with few freezing days have seen large declines.

Wildfires? Not so much anymore. At least not in the sense they’re natural. The fingerprints of human-caused climate change are all over them. Maybe firestorms is a more accurate term.

The fire, flood, hurricane, heat wave, drought, storm surge, or weather whiplash may not have disrupted your community yet, but we’re all paying handsomely for the climate crisis.

“To say CA has always had wildfires is a classic form of climate denial. For years we've heard, ‘The climate has always changed...' that’s just totally disingenuous. The question is whether climate change is making those things worse. The answer is yes." www.yahoo.com/news/yes-wil...

Evidence is mounting that rapid Arctic warming and melting is contributing to worsening fires in western states. For starters: www.nature.com/articles/s41... www.mdpi.com/1999-4907/8/... pmc.ncbi.nlm.nih.gov/articles/PMC...

Any continued #climate denial by politicians or pundits or corporations or self-serving billionaires is no longer just embarrassing, ignorant, or corrupt. It's now increasingly criminal.

“We sound like a broken record but only because the records keep breaking,” said Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, which monitors global temperatures. “They will continue to break until we get emissions under control.” www.nytimes.com/2025/01/10/c...

If you think slowing or stopping #climate change is too expensive, you have it backwards. Failing to slow or stop #climatechange is what's expensive. www.bbc.com/news/article...

A reminder that Los Angeles had its hottest summer in history last year. Southern California has received just 2% of "normal" rainfall during the current "rainy" season. These fires are a direct result of a warming & drying atmosphere caused by burning fossil fuels. We are in a climate emergency.

Yep, our Earth is warming at the hand of humans (it would be cooling if we weren’t here), but frigid spells are still a thing: x.com/bostonglobe/...

Sadly, it’s a good time to once again share this amazing infographic that we ran at @science.org more than 7 years ago 🧪 #IDsky www.science.org/content/arti...

Here’s more on why I oppose using taxpayer funds to deploy DAC technology. drawdown.org/insights/sto...

THIS is how it’s done, folks.

I think Direct Air Capture (DAC) is nowhere near ready to deploy. It’s too expensive, faces huge engineering challenges, and diverts money and attention from better climate solutions. Let’s stop giving fossil fuels a fig leaf on the taxpayer’s dime. news.mongabay.com/2024/12/dire...

I like things science has done to save millions and millions of lives… Vaccines. Clean water. Sanitation. Pasteurization. Fluoride. Next up? Clean air, a stable climate, healthy watersheds, and thriving ecosystems.

Today at #AGU24: In a session co-chaired by BE's @hausfath.bsky.social, @rarohde.bsky.social will be diving into the factors, both well-defined and more unexpected, that contributed to 2023's record-setting ("gobsmackingly bananas") extreme heat. Find us at: 📍GC23K-02 / Salon A ⏰ 14:21 - 14:33

Our new study out today: Despite global and especially Arctic warming, winter cold spells are far from dead. We summarize recent studies and add new analysis: iopscience.iop.org/article/10.1....

This is how to do it, kids: Home insurance is now a climate story. Put it on the front, and put "climate change" at the top. Especially now that deniers will control the federal and state government. www.houstonchronicle.com/projects/hom...

#Arctic air temperature rank by month over the satellite era - now updated through November 2024. Nearly all of the top 10 warmest years per each month are since 2000. + Ranks: 1=warmest (red), 45/46=coldest (blue) + Download visual: zacklabe.com/arctic-tempe...

As a reminder, land areas (where we live) are warming around twice as fast as the oceans. Subsequently, most of us are 'experiencing' temperatures rising faster than the global mean record. Data from NASA GISTEMPv4: data.giss.nasa.gov/gistemp/ ⚒️🧪

The United States is now producing enough domestic solar to cover nearly all annual deployment. That's what policy can do, folks! And a majority of these jobs are in Republican districts.

It’s hard for me to believe that the moderate La Niña can compete with raging marine heat waves across most of the N. Pacific and N. Atlantic in influencing N. America’s weather this winter. Thoughts? www.tropicaltidbits.com/analysis/oce...

Yup.

Mother Nature’s fury is spectacular!

I would love to tell you about the times vaccines prevented me from getting sick, but every time it happens, I don’t notice. I just keep feeling well. Neither do you. Public health, when it’s working, is invisible.

The Arctic's Uncertain Future: eos.org/features/the... by Grace van Deelen at AGU

It surprises me there's so much discussion about this developing weak La Nina and mostly crickets about the raging marine heat waves in the NW Pacific, across the entire N. Atlantic, and much of the Arctic that are sure to have major influences on weather patterns around the N. Hemisphere...
