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.

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 500 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.

    For worried scientists, whether in the United States, where Donald Trump could return to power following the presidential election next November, or in France, Lauren Kurtz gives the following advice: "Be prepared, know your rights, what you can and cannot publish, for example.

  • Conspiracies and cynical indifference are the right’s latest climate strategy

    Researchers from Columbia University and the nonprofit Climate Science Legal Defense Fund report that Trump’s effort to undermine scientific research included 154 documented cases of federal government censorship of scientists. That’s horrifying, and we can’t let it happen again.
