This was such a fun photo to set up, taken by Thomas Reiter through a sleep station window on Mir. The sun was so bright we were all squinting like crazy. But I love how it shows the texture of the Shuttle's rough, protective hide, and the glimpse of humanity (and my moustache) against the universe.

Nations clinched a deal ... that is pointless without an obligation on nations to end all new fossil fuels extraction and development, and to stop the accumulation of CO2 in the atmosphere that is cooking us! FFFS! #COP30

Two billion kids would REALLY appreciate it if we did more about this than just make a few non-binding promises every year & then instantly forget about them.

As I always say when some right-winger starts going on about "red tape that slows innovation", every regulation on the books represents a lesson we as a society learned the hard way, and then encoded so we wouldn't forget. It's someone's blood & pain.

America putting most of its eggs in the generative AI basket, China going hard into green tech. When history looks back on this period, someone is going to look awfully stupid.

The world is fractured. The climate talks reflected that. Delegates from nearly 200 nations β€” not including the U.S. β€” showed they could make some progress. But they deferred the hardest decisions.

#COP30 "exposed the world as it is β€” haltingly and slowly tackling climate pollution, and fragmented by rising economic nationalism and protectionism, rather than the united, optimistic community of nations that produced the Paris climate agreement 10 years ago."

Post image Landscape in limited palette of Payne's Grey, Raw Umber, Green Gold, Old Gamboge & Warm White. Rolling hills dominate the composition: largely dark on the left side of the pass, but with rock and flora detail; Suggestion of a small cottage nestled into the lower hillside, then most of the right half of the panel lit up by moonlight. Small strip of dark night sky at the top, with bright white cloud in front of the moon and a dark line along the ridge, emphasising the curve.

I think this painting might be finished, but I've been staring at it for too long! Oil on panel, 70 x 100cm.

Reducing emissions without phasing out fossil fuels is like being full after a big restaurant meal and telling the waiter to keep delivering new dishes to the table with a promise that your kids and your neighbor who is not even at the table will pay the bill.

I'm of 2 minds about climate negotiations these days.
There's part that invested a decade in COPs as a path to change. That part remembers the feeling of being with thousands of people coming together to try to take care a collective life support system.

Two dead in separate collisions in Waterford and Louth An 18-year-old man and a woman in her 70s have died in separate collisions in Waterford and Louth.

Two more road deaths in urban areas in the last 24 hours. A failure to introduce default 30 km/h speed limits in Built Up Areas reflects poorly on the Irish Government. #VisionZero road deaths? A pipe-dream unless attitudes change. www.rte.ie/news/regiona...

Over the 19 years Ireland has had a derogation from the nitrates directive we have backed ourselves in to a corner. Which now leaves us having productive and economically viable farms or cleaner rivers and lakes, but not both.

Imagine, if you will, that NASA updated its website to suggest gravity might not exist, prompting CalTech and CERN to release statements saying, "With great sadness, we can no longer recommend listening to NASA."

This is what's happening in epidemiology.

I had the a welcome opportunity to move beyond the standard Punch & Judy media setup to properly look under the derogation hood, & explore why the Government measures are failing our waters & failing our farmers.

The Irish Times published and lauded John Collison's op-ed, but did they fact-check it?

Andrew Jackson did. Thoroughly.

If you spent time reading the original, you'd want to give time to this counterpoint as well.

Science will often take you to unexpected and delightful places. In this study, researchers hypothesized that riders in a crowded subway car would be more likely to offer their seat to a pregnant person if there were someone in the subway car dressed as Batman πŸ§ͺπŸ¦‡

Brown begins work on $7 million microplastics research initiative Brown’s team in the SIMCoast initiative will focus on modeling microplastics in the Narragansett Bay. 

Brown faculty, including IBES fellow @baylorfk.bsky.social & affiliate @maratimes.bsky.social, are part of the new SIMCoast initiative modeling microplastics in Narragansett Bay.

β€œIt’s a fantastic way to do interdisciplinary work and learn from others,” Freilich told @browndailyherald.bsky.social.

With all eyes on the big COP30 agenda items, WIM review talks have stalled.

Negotiators and civil society observers say it has come down to Kenya blocking the decision.

This goes back to Kenya wanting to host the Santiago Network secretariat in Nairobi. It says current host Geneva is too expensive

As the final text is being hammered out here in BelΓ©m for #COP30, the issue of fossil fuel phase-out is on the table again.

Looking at the actual numbers from the IPCC AR6 1.5Β°C assessed scenarios to decompose reduced fossil fuel output vs. carbon capture and storage - CCS (i.e. abatement)
