The Environmental Protection Agency no longer features a climate-change section on its main website, but the scrubbed pages are available from several sources.
Some individual pages are still available via EPA's search engine, but they may yet vanish in the new administration's ongoing purge, and they are no longer organized under a climate-change heading.
"The first page to be updated is a page reflecting President Trump’s Executive Order on Energy Independence, which calls for a review of the so-called Clean Power Plan," the agency stated in a news release. "Language associated with the Clean Power Plan, written by the last administration, is out of date. Similarly, content related to climate and regulation is also being reviewed."
But the Obama-era EPA website survives on EPA servers at 19january2017snapshot.epa.gov, as it appeared the day before Donald Trump took the oath of office.
Its climate-change pages are here.
If you don't trust EPA Administrator Scott Pruitt to preserve those Obama-era pages, you don't have to. Anyone can download a copy of the EPA website as it appeared at the end of the Obama Administration from the Internet Archive's Environmental Protection Agency Mirror. The uncompressed file expands to about 50 Gigabytes.
Older pages from various moments in time also available from archive.org's Wayback Machine.
Since Trump's election a number of groups have formed or mobilized to protect climate data and other scientific information to which the Trump Administration has seemed hostile, including the Environmental Data and Governance Initiative, the End of Term Archive, the California Digital Library, the Data Refuge Project, Climate Mirror, and a network of concerned librarians, the Libraries+ Network.
Together they are processing data on a comprehensive archive of government information available before Trump took office. "We are all processing the data now," said Jefferson Bailey,director of web archiving for Internet Archive, which sponsors the End of Term Archive. "It will take a while to index, get the custom access portal up, and do analysis."
Meanwhile NOAA's chief data officer, Edward J. Kearns, has tried to assure scientists, librarians and activists that the government's archived data is not at risk.
"I am sometimes asked if NOAA’s data in its archives can be easily deleted," Kearns said in a post that appeared April 30 on the Libraries+ Network blog.
"No they can’t, since data may not be removed without significant effort and public deliberation. It is also unlawful to tamper, damage, delete, vandalize, or in any way alter formal federal records , including NOAA’s environmental data and its archives. There are data disposition schedules and defined NOAA processes that help us to meet the intended outcome of well-executed and efficient data preservation, which prescribe public notice and comment periods, by which NOAA may propose to remove data from its archives. Such removal has been rare."
Kearns became chief data officer March 30. He first joined the National Oceanic and Atmospheric Administration in 1996 as an oceanographer.
