A cikin shirin kimiyyar duniya, NASA tana bincike da kuma buga kan al'amuran yanayi. Its statements concur with the interpretation that the global climate is heating. Bob Walker, who has advised president-elect Donald Trump on space issues, has advocated that NASA shut down its climate study operations. The *Washington Post* reported that NASA scientists copied data on climate change held on U.S. government computers, out of a fear that a Trump administration would end access to data on climate change.
