France passed a law requiring solar panels on every parking lot with more than 80 spaces.

Equals 10 nuclear reactors
Reduces heat island, shades cars

The US -- 800 million parking spaces. Most of them are uncovered asphalt sitting in direct sunlight.

Why aren't we doing this?

This is an important point to remember every time some yahoo politician who wants to defund the NSF reads the title of a grant in dumbstruck tones: "They're studying the venom of Gila monsters? What? Who's *that* for?"

All of us, Gomer. It's how science actually works.

Cycling Linked to Lower Risk of Dementia, Study of Half a Million Finds Getting from A to B on a bicycle more often could reduce risk of dementia, possibly by protecting a part of the brain tied to memory functions, new research finds.

“Compared with non-active travelers, the cyclists had a 19% lower risk of all-cause dementia, a 22% lower risk of Alzheimer's, a 40% lower risk of young-onset dementia (before the age of 65), and a 17% lower risk of late-onset dementia.”

Getting around a bike more often could reduce dementia risk.

what about blockading the strait of hormuz?

It's already blockaded

It's been blockaded once, yes. What about second blockade?

Data centers can increase pollution, raise utility costs, and burden entire electrical grids.

I am proud to be an original cosponsor of the Power for the People Act to hold data centers accountable for their own electrical costs and establish incentives to reduce their impact on the power grid.

A chart from Our World In Data, showing the shift away from coal power in the UK - nearly 70% of electricity production in the late 1980s, to less than 0.1% in 2025.

A chart from Our World In Data, showing the shift away from coal power in the UK - nearly 70% of electricity production in the late 1980s, to less than 0.1% in 2025.

There's a lot being shared right now about China's incredible shift towards renewable energy - and rightly so.

But this, from the UK, is equally astonishing & encouraging.

It's not just that change can happen. It's that it *is* happening.

The dangerous myth of ‘neutral’ technology The notion that innovation is value-free conceals the political and ideological agendas behind it

Palantir's UK head Louis Mosley wants us to believe that tech like theirs is neutral until their clients decide how to use it. People who study science, technology and society have long exposed such arguments as fallacious. My latest column for TNW.

Every sensible government will spend the coming months accelerating the deployment of solar, batteries, heat pumps, and EVs, especially for lower income households. It’ll be a hell of a lot cheaper in the long run than subsidising fossil fuels the next time prices spike, which they will.

More Crops Grown for Fuel and Livestock Feed Than for People, New Study Finds Cutting back on beef and biofuels could help improve food security and mitigate climate emissions.

The biggest problem with the food system is that it is no longer a *food* system.

More than half the calories we grow on croplands aren't food; they're lost in inefficient feedlots or to biofuels.

Project Drawdown scientists highlight this disturbing trend:

The DEA does not employ anyone with medical credentials. It is a law enforcement agency that practices medicine, to the point they can literally deny Americans evidence-based medicines from patients’ own doctors. Since it was conceived, the US drug scheduling system has never been based on evidence.

I think not enough people understand that the pushback against renewables and EV's is money.

Without getting too in the weeds: renewables cannot ever be as profitable as oil and gas.

EV's don't make as much money as gas guzzlers.

That's it. That's all you really need to know.

As Iran war exposes global dependence on fossil fuels, the biggest emitters are reaping the rewards Worst polluters hold world’s future in their hands as they benefit from higher fossil fuel prices, but global trends favour renewables

This illegal war on Iran is benefitting very few people and screwing everyone else now and in the future.

Any 2028 POTUS Candidate who wants my vote had better have a clear and AGGRESSIVE PLAN to get us OFF of reliance on oil and gas.

Like, New Deal level investment in solar and other clean and renewable energy.

They could call it the “Green New Deal,” or something like that.

oh come on. #Vienna is lovely and I absolutely loved the #summer I spent there. I think big part of it is it's super #introvert friendly. #Museums, #concerts. As an introvert from the least introvert-friendly country on Earth (well, I guess both the US and India count for that), it was heavenly lol

Massive budget cuts for US science proposed again by Trump administration Budget proposal would also curb federal payments for scientific publishing.

I will say this again: Science isn’t just something that nerds do, it’s the foundation of the modern world.

It’s why this app exists. It’s why child mortality rate isn’t 50% anymore. It’s how we’re able to launch people to the moon. It’s how we’re able to grow food that feeds half the world.

Now that everyone’s paying attention to global energy markets and effects of faraway events on prices and decision-making, is it a good time to talk about the indirect land use effects of dedicating cropland to biofuel production or nah?

The Farm Bureau estimates that a year-round increase from E10 to E15 (15% ethanol blend in gasoline) would increase US corn demand by 2.4 billion bushels a year.

Latest yields per USDA are 188.8 bushels/acre, so growing it requires another 12.7 million acres. That’s about half the size of Indiana.

Congrats to the Project Drawdown team. Looks like a useful update of one of my fav papers, @enviroem.bsky.social et al 2013.

Feeding more crops to people & fewer to animals & vehicles would make it way easier to feed 10B people and end deforestation, stabilize the climate, cut water pollution etc.

Only half of calories produced on croplands are available for human consumption, study finds Study: 1/2 of the calories produced on croplands are unavailable for human consumption

This is one of the most important issues with the global food system, yet it is often ignored.

Put simply, we don't actually grow much *food* in our farms around the world. Instead, we grow grossly inefficient animal feed and biofuels.

I’m staying in a #hilly part of DC this stretch. A week ago I was panting like a pup on a hot day, but after a week of around 15,000 steps a day I’m breathing normally and not breaking a sweat.

It is absolutely gobsmacking to me that the media and research elite have so disavowed climate change that they cannot see that the Trump regime's both domestic and foreign policy centers on securing American control over the fossil fuel economy, despite accelerating impacts of global heating.

RFK Jr. fired all of the legitimate scientific experts on the Advisory Committee on Immunization Practices and replaced them with unqualified political appointees.

A judge just ruled that the new members were not appropriately appointed, so ACIP cannot meet this week to spread more misinformation.
