Global Change Research Act of 1990

The Global Change Research Act 1990 is a United States law requiring research into global warming and related issues. It requires a report to Congress every four years on the environmental, economic, health and safety consequences of climate change.
According to a summary by the Congressional Research Service, the Act:
Following the publication of the first National Climate Assessment Report there were accusations that information was being suppressed, leading to complacency around public works, such as New Orleans flood defences. Greenpeace, the Center for Biological Diversity and Friends of the Earth challenged the delay in federal district court on August 21, 2007. A judge ruled that an updated national assessment must be produced by May 31, 2008.
