The data and reports and all the rest won't be "lost" even if Donnie's minions try to make them go away.

Yes, it will be harder to find, and it will be easier for his people to ignore the science and change the framing, but the data and knowledge is still there and available to the scientists and the public.

Similarly for http://web.archive.org/web/20170119192520/https://www.climate.gov/ and the other "inconvenient" government sites.
