At the end of January 2019, huge swathes of the US were blanketed with snow, and winter storm warnings were in place across several states. U.S. President Donald Trump, who has made it clear that he believes climate change is an overblown hoax, took to Twitter to suggest that "a little of that good old fashioned Global Warming" would be welcome.
Trump has fallen into the same trap that many people around the world do: conflating "climate" and "weather." The U.S.'s current snow storms and cold snap are an example of weather — they will persist for a couple of days to a few weeks at maximum, but will eventually stop and make way for clear skies and inevitably a warm summer for much of the U.S.
This confusion is common. So, what is the difference between "weather" and "climate"?
