claimed that climate change was a Chinese-sponsored hoax?

Trump has made various similar remarks about climate change. After becoming President, he vacillated on the issue, going between claiming that cold snaps disprove global warming, while also alleging that his administration had done much to combat climate change.

Trump has also claimed that windmills cause cancer, and withdrew the US from the Paris Agreement. He has dismissed UN climate reports.

His administration has rolled back several regulations, including for endangered species, offshore rigs, and coal pollution.

The Department of Defense has listed climate change as a national security threat since before Trump’s presidency. It has not commented on the health risk of windmills.
