Long before he even declared his run for the White House, Donald Trump has been issuing periodic statements affirming his belief that man-made global warming is a myth, meant to stifle US manufacturing. While as recently as 2009 he was cosigning letters with other business leaders calling for “meaningful and effective measures to control climate change,” since about 2011 he has been tweeting his climate denialism regularly, a denialism that culminated in his exiting the Paris climate agreement.
Most of his tweets involve some kind of confusion between climate and weather (“hey, it’s cold outside, global warming must be fake”) or condemnation of President Obama for making climate change a priority, which Trump interpreted as foolish. While the vast majority of the tweets predate Trump’s campaign, a couple were issued during the 2016 Republican primary, where this kind of climate change denial was common among candidates.
Here’s every Trump tweet I could find on the topic, from 2011 onward (concluding in October 2015).
It snowed over 4 inches this past weekend in New York City. It is still October. So much for Global Warming.

In the 1920's people were worried about global cooling–it never happened. Now it's global warming. Give me a break!

Let's continue to destroy the competitiveness of our factories & manufacturing so we can fight mythical global warming. China is so happy!

CLICK HERE We can't destroy the competitiveness of our factories in order to prepare for nonexistent global warming. China is thrilled with us! The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive. In the 1950’s our climate was far more unstable than it has been over the last 5 years. It's freezing and snowing in New York–we need global warming! The World Bank is tying poverty to ‘climate change’ http://t.co/wZ9ofqxJ And we wonder why international organizations are ineffective.
