Barack Obama

@barackobama.bsky.social

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate change—all so the fossil fuel industry can make even more money.

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org

There is No Scientific Justification to Revoke the Endangerment Finding

The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

State capture by the fossil fuel lobby.
The US descends into a banana republic. It would almost be funny if the consequences wouldn’t be so dire for billions of humans, if the courts don’t stop this folly soon.

EPA isn't now denying that climate change is happening. Instead they are saying that whatever the U.S. does now will not make enough of a difference to warrant the expense to Americans.

The U.S. is historically the largest emitter of greenhouse gases, and is abdicating its responsibility.

Trump says climate change doesn’t endanger public health – evidence shows it does, from extreme heat to mosquito-borne illnesses

Climate change is making people sicker and more vulnerable to disease. Erasing the federal endangerment finding increases the risk.
