I feel this. Anger is a valid emotion right now. The NSF is being hollowed out. “I don’t think we rebuild science without getting mad”. -Kate Marvel Former NASA Scientist 🧪
For me, there is no contrast, no tension,
between being a human being and being open about your values and emotions and what you would like to see in the world, and at the same time, getting the math right.
I think it's lying when we pretend that we are perfectly objective and unhuman. We're not.
But at the same time, we do have a responsibility to look at the data, to change our minds where necessary, and to get the numbers right...
I don't think we solve this without getting mad. I don't think we rebuild science without getting mad."

In addition to legal experts @envirojustice.bsky.social , I'd add that environmental & conservation science experts also call for real reform, not more rhetoric, slippery words, and confident endorsements or centrist exhortations that are flatly wrong (next post & embedded🧵 if u'd like more info)
Excerpt from Environmental Justice Australia's media statement on Minister Watt's EPBC reform package

"
The reform package has small positive elements:

• Including definitions of "critical habitat" and "unacceptable impacts" in the Act is an improvement, but they are undermined by discretionary powers elsewhere.
• A national EPA is welcome, but it won't have power to make positive decisions for nature.
• Better enforcement and penalties for those that break the law are overdue and welcome.
• National environmental standards are sorely needed as the cornerstone of meaningful reforms, but we are yet to see them, and the way they would apply would make them discretionary, weak, and too often unenforceable.

However, the reform package also has deeply concerning elements that need fixing:

• No assessment and prevention of climate harm to nature.
• No end to logging and land clearing loopholes like Regional Forest Agreements and
"continuous use" exemption.
• Widespread political discretion undermines key positive improvements.
• The offsets scheme is deeply problematic and essentially a "pay-to-destroy" model with minimal checks and balances.
• Handing decisions of national and international significance to states and territories who are ill equipped to make these decisions.
• First Nations rights are largely sidelined: there is no Free, Prior and Informed Consent (FPIC) embedded in the Act and no First Nations Engagement Standard, as recommended by Samuel.
• Recovery plans for threatened species and habitats can be overridden by Ministerial protection statements.
• The Environment Minister can decide to switch off important safeguards for offshore gas and petroleum projects - impacting consultation with First Nations communities and environmental assessment
