EVs beat petrol cars on lifetime emissions — even on “dirty” grids.
Battery production is carbon-intensive, but EVs quickly repay that debt and end up 21–71% cleaner over 250,000 km.

We can’t wait for perfect grids: electrify transport and clean the grid now.

It's very important that prospective home buyers and tenants have information about the climate risks of where they are considering moving. It's a real setback to climate adaptation that this information is being removed from Zillow. FEMA flood maps cannot be relied upon. bit.ly/4op4Vsw

This new study shows the risk that flooding worsened by climate change poses to toxic sites. As I wrote in 2023, the U.S. regulatory system is ill prepared to deal with this threat, but there are ways the laws can be changed to address it. bit.ly/4igwWRG

As I describe in detail in my new article in the New York Law Journal, the Trump administration has taken an all-of-government approach to squelching wind and solar.

Climate victory: NY court rules that State Dept. of Env. Conservation must issue its GHG cap-and-invest rules, as required by NY Climate Leadership & Community Protection Act, by Feb. 6. DEC was ready to issue the rules but Gov. Hochul stopped them. Next question: Will they appeal?

The US became the world’s leading nation due to its science and technology, and it has now decided for a path of self-mutilation and handing world leadership over to 🇨🇳.
Why? 🙄

As part of the budget proposal for NASA submitted earlier this year, the Trump admin proposed cancelling over 40 missions.

Agency employees have already been instructed to do the prep work for ending these programs, according to a NASA scientist.

NASA missions at risk under the Trump administration
Some satellites slated for decommissioning are in the prime of life, and turning them off would be enormously wasteful, in addition to severely limiting scientists' ability to understand the planet.
