Protecting the Scientific Endeavor
Science Under Siege
The Climate Science Legal Defense Fund has fought for the scientific endeavor since 2011. Our initiatives ensure that scientists can conduct, publish, and discuss their research and advocate for science without the threat of political harassment, censorship, or legal intimidation.
2025 Impact Report
We are fighting back against the flood of anti-climate and anti-science actions.
Climate Litigation Toolkit
Our free legal resources explain the best practices for safely and effectively engaging in climate litigation and other scientific consulting work.
Updated Report: Open Records Laws
These laws, while critical to government transparency, are frequently misused by groups seeking to harass scientists and slow or halt the scientific endeavor. This report can help scientists and attorneys respond to such inquiries.
Political Action Toolkit
Our free legal resources explain the best practices for safely and effectively engaging in political advocacy.

Our Work
We provide free legal aid and resources to researchers, educate the scientific community about their rights and responsibilities, and strengthen legal protections to promote scientific integrity.
Silencing Science Tracker
The Silencing Science Tracker is a public database that tracks government efforts to restrict, censor, undermine, and misrepresent science since the November 2016 election. To date, we have documented more than 600 attacks on science. We catalog government efforts to restrict, censor, undermine, and misrepresent science.
Safeguarding Scientific Integrity
We promote scientific integrity reforms to ensure the best available research and data inform government decision-making. And we publish resources to advance understanding of how research institutions and federal agencies approach scientific integrity — and how to strengthen legal protections for science and scientists.
