Expert Working Group on Climate Change and Health in the United States Comment on EPA's Proposed Reconsideration of 2009 Endangerment Finding

The Trump administration wants to repeal the 2009 "Endangerment Finding", arguing that greenhouse gases don't actually harm health and well-being. A group of 100+ experts reviewed the literature and disagrees. We brought the receipts (400+ references). Full comment at zenodo.org/records/1728...

Earlier this year, Dr. Jane Goodall sat down for an interview for Brad Falchuk’s new Netflix series, Famous Last Words.

The premise of the series is to interview people on the condition that the interview not air until the subject has passed away.

There are many things wrong with this idea, including:
1) Universities aren’t people. I may or may not believe what university leadership believes.
2) Research (at least for health) should be judged on whether it has good ideas for making people healthier. Less merit means worse health.

EPA tells scientists to stop publishing studies, employees say Staff from the EPA’s Office of Water were summoned to a town hall meeting this week and told to pause the publication of most research, pending a review.

Can't publish science without political approval, what could go wrong

In a single email, the EPA ended her research into how climate change endangers children Jane Clougherty spent years studying how extreme weather affects kids’ health, but as climate threats continue to rise, the Trump administration cancelled her work.

The EPA cancelled grants that would help us understand how children are affected by climate change.

The agency response: Maybe Biden and Harris "shouldn’t have forced their radical agenda of wasteful DEI programs and ‘environmental justice.'"

White House Orders Agencies to Escalate Fight Against Offshore Wind

The assault on wind is very similar to the assault on vaccines - ginning up evidence to support a desired policy that harms public health. Offshore wind is good for climate, air quality, and overall grid reliability.

The institutions that protect our health and safety - CDC, EPA, etc. - are being deliberately destroyed in a manner that will be hard to undo.

Whether this is to boost favored industries, pandemic backlash, or because ideology trumps evidence, the outcome is the same. We will be less healthy.

Improving Oversight of Federal Grantmaking By the authority vested in me as President by the Constitution and the laws of the United States of America, and to improve the process of Federal

1. Federal funding for research promotes tech, biomedical, and scientific discovery in the US, and provides training for the sci/tech workforce that has brought immeasurable wealth to the US over the past 75 years.

Today's executive order includes a provision that will obliterate both functions.

I don’t want political appointees from this administration deciding what is meritorious research. But I wouldn’t want political appointees from ANY administration deciding that. That would mark the end of basic research, research with long-term benefits, etc.

Great example of how citizen science measurements of air pollution can be aggregated to provide meaningful regional and national data. At a time when federal data are disappearing or becoming less reliable, locally generated and compiled data will take on increasing importance.

Trump Environmental Protection Agency moves to repeal finding that allows climate regulation President Donald Trump’s administration has proposed revoking a scientific finding that's long been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change.

Lead sentence in this article is key - EPA proposes "revoking a scientific finding" that greenhouse gases endanger public health and welfare.

The thing about a scientific finding is that it is based on evidence. You can't revoke it just because it is inconvenient.
