The news of Zeldin’s plan comes on the very same day the United Nations’ top court ruled that countries have a “duty” to limit greenhouse gas emissions. Those that fail to take steps to protect the planet from climate change, the International Court of Justice said, may run afoul of international law.

Under Zeldin, the EPA announced it would shutter its Office of Research and Development, which provides expertise for environmental policy and regulation, and analyzes the dangers of climate change and pollution. The agency is also expected to shed thousands of employees, including chemists, biologists, and toxicologists.

EPA plans to reverse endangerment finding, a foundation of the federal government's ability to address climate change.
