One of the most compelling climate graphics. Right up there with the Hockey Stick and the Keeling Curve.

This is happening on our watch.

It’s 50 years past time to clean this mess up. Now is the next best time to make a difference.

Just to say, if you are 30, more than half of all human fossil fuel emissions have occurred in your lifetime #dataviz

What does it matter if 72% of Americans think global warming causes droughts?

Don’t the correlated science & meteorological records bear that out regardless of what people think, including the 28% that get this dead wrong?

Bring back experts — Retire “man-on-the-street” polls and interviews.

And that just measures the energy produced, not the relative emissions. Producing and burning ethanol pollutes and produces greenhouse gasses to a vastly greater degree than solar panel implementation.

Over 40% of corn grown in Indiana is used to make ethanol that cars burn. One acre of corn yields about 16,500 vehicle-miles per year of ethanol, which sounds high until you realize that one acre of solar yields about 2,700,000 vehicle-miles per year: 16,000% more driving for a given plot of land.

Great episode! Gotta get your new book! You 3 are some of the best climate writers, scientists, and policy influencers, movers and shakers out there. Thanks for the meaningful and much needed and appreciated work!

It’s actually on brand. All their terms meant to inflame or insult are synonymous with “bogeyman.”

DEI, Antifa, Woke, BLM, CRT, RINO, etc.

When any of them get stale or totally debunked a fresh one or two will arise, hydra-like, in its place.

Kill inanimate code or living artists?

It’s gotta be some kind of trick question? Can’t we just choose based on how few people can make the most money at the expense of creative individuals?

[social media really needs a sarcasm font.]

And 47 thought the DOD needed a new name. Maybe DOE should become Dept. of Fossil Fuel Prolongation and Climate Change Acceleration.

It is worse than the fox guarding the chicken coop — it is the foxes lining up to protect the other foxes and coverup their wanton rampage through the chicken coop, hatchery, and razed free-range grazing grounds.

Yale Program on Climate Change Communication @yaleclimatecomm.bsky.social · 2d

A report from two nonprofits found that 25 of the 37 nominees to federal environmental positions had ties to polluting industries, like oil, gas, and mining. The report explicitly links individuals within the Trump Administration to fossil fuel companies.

Hiding the truth and replacing it with illegal lies does not make the truth or laws go away.

Eat less meat. When dining out, try the vegan or veggie options you maybe wouldn’t fix at home. Gives you some variety and ideas and rewards restaurants that offer more climate-friendly meals.

Project Drawdown @projectdrawdown.bsky.social · 7d

“Nothing else on a pound-for-pound basis, except maybe refrigerants, comes close to the polluting power of beef. That doesn’t mean everyone has to be vegan tomorrow, but the goal should be to trim back high-polluting parts of one’s diet" - @globalecoguy.bsky.social

Want to eat more plant-based meals? Maggie Baird, Billie Eilish's mom, has some ideas

Have you heard replacing meat with plant-based foods is better for the planet and can be better for your health too, but you don’t know where to start?

Oh please! That this is even a question in CA where clean energy has otherwise made such strides relative to the rest of the nation is troubling.

Public Utility Commissions are there to serve the public. Revenue from ratepayers should not be used against their (& the planet’s!) interests.

This sounds like something worth emulating.

Dr. Jenny Morber @jrmorber.bsky.social · 3d

“so long as you choose one terrible thing to pay attention to — and, crucially, do something about — then it’s okay to block out all the other terrible things if you need to. This one thing should be something you profoundly care about, that you can bring your gifts to bear on to make a difference.”

A baby has died of whooping cough in Mississippi amidst their worst pertussis outbreak in more than a decade.

If you have a loved one with an infant or are near babies a lot, please consider getting a pertussis booster, as is recommended by legitimate science and healthcare professionals.

Mississippi Baby Dies of Whooping Cough Amid Rising Cases

A baby in Mississippi has died of whooping cough for the first time since 2012. The baby was less than two months old—too young for vaccination.

Just posting this. Everyone knows why.

Text of the fourth amendment “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”

Ours went up and we’re on Medicare.

Trump and the GOP own these increases.

They will be absolutely crippling for some people. That includes a lot of people from low to middle income, about 1/3 of whom didn’t realize they voted for this when they voted for Trump.

Stop him and save America.

The U.S. is probably going to lose our elimination status for measles in 2026.

Anyone tired of so much “winning”?

MAHA is a toxic infection of the brain that spreads via social media and results in the rejection of scientific fact, followed by disease and death.

Even if you support massive deportation operations, under no circumstances should ANYONE be ok with US citizens being forcibly removed from their homes and detained without explanation.

This is a clear violation of their constitutional rights and should universally condemned.

Wasting what I assume are taxpayer dollars to produce a copyright-infringement video literally celebrating the death & suffering of opponents is right up there with the worst examples of “waste, fraud, and abuse.”

Evil masters of projection strike again. At everyone else’s expense.
