New images could change cancer diagnostics, but ICE detained the Harvard scientist who analyzes them Without scientist Kseniia Petrova’s expertise, no one can fully unlock the data’s potential, putting crucial advancements in early cancer detection at risk.

“A groundbreaking microscope at Harvard Medical School could lead to breakthroughs in cancer detection... But the scientist who developed computer scripts to read its images and unlock its full potential has been in an immigration detention center for two months” www.nbcnews.com/news/us-news...

wake up! you’re already behind on so much bad news!

Rising global temperatures can influence the timing of events, such as when crops are ready to plant and harvest and when flowers and trees bloom.

One example is the timing of the peak cherry tree blossom in Kyoto, Japan, where records stretch back to the ninth century — that’s over 1200 years.

The Trump Administration Accidentally Texted Me Its War Plans U.S. national-security leaders included me in a group chat about upcoming military strikes in Yemen. I didn’t think it could be real. Then the bombs started falling.

You cannot make this shit up. Sharing this jaw-dropping story with a gift link -- give it a read.

UK insurers paid out record £585m last year as climate breakdown intensifies Insurers blame ‘significant and consistent bad weather’ after year of 12 named storms

Expect your home insurance premiums to go up as bad weather gets worse. Wouldn't it be better if the companies causing global heating were to pay up instead 🤷🏽

You can ignore climate change. The political system can ignore climate change. But the insurance industry cannot ignore climate change.

Mortality impacts of the most extreme heat events - Nature Reviews Earth & Environment Extreme heat is increasing in magnitude and frequency, threatening human health. This Review assesses mortality risk associated with extreme heat, revealing that human thermal tolerances (that is, unc...

🔥🌡 Extreme heat is getting deadlier

Since 2000, over 260,000 deaths have been linked to extreme heat.

If global warming hits 2°C, areas where heat surpasses human survival limits will triple

I am glad that NOAA greenhouse gas monitoring information is back online - the website was inaccessible due to planned power maintenance.

I have removed my earlier message.

It's a bummer that this is necessary, but the federal data archiving collaboration we're part of has created an independent mirror of the EJScreen tool here: #EnergySky

Bioaccumulation of microplastics in decedent human brains - Nature Medicine Pyrolysis gas chromatography–mass spectrometry reveals the presence of microplastics and nanoplastics in human kidney, liver and brain tissue samples from 2016 and 2024, with higher proportions found ...

🧠⚠️ Microplastics found in human brains

New research confirms microplastics accumulate in human brains, with concentrations increasing over time.

Higher levels were also found in dementia cases.

Climate data from @copernicusecmwf.bsky.social shows, it is virtual certainty that 2024 will be the warmest year on record and the first calendar year above 1.5°C.
This does not mean the Paris Agreement has been breached, it means ambitious #climateaction is more urgent than ever

Polar stereographic map showing 2-m air temperature anomalies in October 2024 for the Arctic Circle with red shading for warmer anomalies and blue shading for colder anomalies. Most areas are warmer than average and well exceeded the colorbar maximum of 5°C above average. The baseline is a 1981-2010 reference period using ECMWF ERA5 data.

Yes, I realize that my usual temperature anomaly scale is less than ideal for visualization purposes in this image here. But that's also because the #Arctic was absurdly warm compared to the 1981-2010 climatological average in October 2024.

Just to emphasize: Saudi Arabia *and only Saudi Arabia* was sent a draft of the COP29 negotiating documents *by the COP presidency* so that Saudi Arabia alone *could edit it directly*.

I got to interview the CEO of ExxonMobil for a climate podcast. The prep was intense. Then with the Bloomberg Green crew, we just published an epic annotated transcript. Give it a read and share your feedback!

It’s our urgent job to show that people don’t need to choose between caring about the fires and storms threatening their homes and their equally urgent need to economically survive.
