i feel like this story is particularly important right now, because protein-maxxing is *so* in vogue. before working on this, i believed i was woefully protein deficient

it turns out that's just a myth that has been floating around for decades—the average american gets more than enough protein!!

my latest investigation for @consumerreports.org is based on months of reporting and 60+ lab tests of leading protein supplements

we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day (🧵)

The widespread die-off of coral reefs represents the first climate "tipping point," according to the Global Tipping Points Report 2025. The report notes that our "new reality" is a series of tipping points with potentially catastrophic impacts.

Tipping points are real but get garbled in reporting. This piece explained the nuance well.

"Every fraction of a degree in warming that humans prevent reduces the risk of runaway #climate conditions... #Tippingpoints highlight the stakes, but also underscore the [value of the choices we can make]."

Climate tipping points sound scary, especially for ice sheets and oceans – here’s why there’s still room for optimism

A report warns that coral reefs may have reached their tipping point, and ice sheets, ocean currents and the Amazon are at growing risk. But, what does that actually mean?

We must get off this path as soon as we can.

We must directly confront this system of deeply inequitable and deadly fossil-fueled capitalism, which has become a planet-sized runaway diesel engine.

"The more fossil fuel we burn, the hotter the planet will get. This is basic, rock solid, incontrovertible, unassailable physics. It's a dead certainty."

Extreme heat, wildfires, floods, migration, food system collapse—it's all driven by increasing global heat. /1

Climate tipping points are irreversible changes in Earth’s systems like ice sheets and rainforests, but swift action can still prevent the worst impacts.

NEW: There’s a disaster unfolding in Alaska right now. And no major network is covering it.

The remnants of Typhoon Halong battered western Alaska overnight. Homes, with people in them, have literally been swept into the Bering Strait.

At least 20 are missing. No comment from any federal agency.

Animal agriculture is a daily horror for gentle animals… on an incomprehensible scale.

It wastes resources and contributes massively to global heating.

Humans do not need to consume the tortured and slaughtered products of animal agriculture.

Peter Singer @petersinger.info · 2d

Factory farming isn’t necessary to feed the world. It actually reduces the food available to humans. We feed grain and soy to animals, but much of it is lost keeping their bodies warm or building body parts we don’t eat.
