Explained: How Can We Have Global Warming and Extreme Cold Weather?
February 1, 2019
You may have seen the tweet from the President wondering how we can be experiencing global warming (or “global waming” as he put it) with such cold temperatures and the current Polar Vortex.
Below, great explainers from trusted sources about just how climate change works and how it is connected with extreme weather, like the recent cold snaps.

Every time it snows on the US east coast, there’s at least one politician or pundit who trots out the old chestnut: “Global warming?! Global cooling, more like!” This episode tackles that myth + explains how climate change affects the polar vortex, too: https://t.co/hX7yep8ZTE pic.twitter.com/907HQ7ohr5

In Chicago, “the risk of almost instant frostbite.”
In Australia, the kindergartner who “will hardly have seen rain in her lifetime.”

Just a reminder. US is 2% of Earth. Australia is record hot. Earth Monday was 0.72 dF (0.4 dC) warmer than 1979-2000 average. Weather is not climate. Weather is fleeting, varies in locales. Climate is long-term, large area. Weather=mood; climate=personality. pic.twitter.com/83wavVonfe

In January, there were 651 record daily highs across the U.S., compared to 321 record daily lows — a roughly 2-to-1 ratio.
Globally, the ratio of record highs to lows was about 20-to-1, with new all-time records in Namibia, Chile, and Reunion Island.https://t.co/bfyyrLAn9u

The polar vortex betrays a difficult-to-perceive change in how U.S. winters unfold: It’s this cold much less often, which makes the freeze bite much more deeply pic.twitter.com/fsZuRbq30s

I created a video that tries to explain the connection between #Arctic change, the #PolarVortex and severe #winter weather including #snow and #cold. The occasion of #PolarVortex2019 seems like a good time to release: https://t.co/DD0Gj6JEAw

It is dangerously cold in central and eastern US. Yet the planet overall is still 0.3°C warmer than “normal” – and that “normal” is ~0.6°C warmer than pre-industrial times. pic.twitter.com/HCOD7aTuCL

Trump always dismisses climate change when it’s cold. Not so fast, experts say. https://t.co/N3OAihdVGp

You know what? No. Explaining weather to Trump is like trying to explain grammar to a potato, the reasoning might be sound but the spud doesn’t understand English. https://t.co/gc66YyD9Ts

Think this #polarvortex was cold? It should have been colder. The clear #globalwarming signal is in decline, warming of such events, @NOAA's Ken Kunkel, #NCA4, @EPA, other studies show. My @natgeo story: https://t.co/F3en34nFnr 1/ pic.twitter.com/FrMxb9Y8w6
