WASHINGTON — The Environmental Protection Agency has removed dozens of online resources dedicated to helping local governments address climate change, part of an apparent effort by the agency to play down the threat of global warming.

A new analysis made public on Friday found that an E.P.A. website has been scrubbed of scores of links to materials to help local officials prepare for a world of rising temperatures and more severe storms.

The site, previously the E.P.A.’s “Climate and Energy Resources for State, Local and Tribal Governments” has been renamed “Energy Resources for State, Local and Tribal Governments.” About 15 mentions of the words “climate change” have been removed from the main page alone, the study found.

Among the now-missing pages are those detailing the risks of climate change and the different approaches states are taking to curb emissions. Also edited out were examples of statewide plans to adapt to weather extremes.
