Global Change Research Act

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; however, the first of these, the National Assessment on Climate Change, was not published until 2000.[1]

The law codified the US Global Change Research Program (USGCRP), set up by presidential authority in 1989, and mandated the creation of the Global Change Research Information Office (GCRIO), which began work in 1993. The act requires extensive reports to be updated and distributed every four years.

To date the 2000 report was the only one produced, and 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 and in a District Court on August 21, 2007 a judge ruled that an updated national assessment must be produced by May 31, 2008.
