The Connection Between Climate Change and Extreme Weather
February 16, 2019
How is climate change connected to extreme weather? Below, we’ve roundup up reports and posts by scientists and experts to explain the connection between climate change and extreme weather.
The Difference Between Weather and Climate
“Though they are closely related, weather and climate aren’t the same thing. Climate is what you expect. Weather is what actually happens…” More from NOAA….
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

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

Climate Change and Extreme Temperatures (Hot and Cold)
In Chicago, “the risk of almost instant frostbite.”
In Australia, the kindergartner who “will hardly have seen rain in her lifetime.”

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

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

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

Climate Change and Hurricanes
“Hurricanes are strengthening faster in the Atlantic, and climate change is a big reason why, scientists say” (Chris Mooney and Brady Dennis, Washington Post)
The study, published in Nature Communications, describes its conclusion in blunt language, finding that the Atlantic already has seen “highly unusual” changes in rapid hurricane intensification, compared to what models would predict from natural swings in the climate. That led researchers to conclude that climate change played a significant role….More…
Climate Change and Precipitation
Rising temperatures will intensify the Earth’s water cycle, increasing evaporation. Increased evaporation will result in more storms, but also contribute to drying over some land areas. As a result, storm-affected areas are likely to experience increases in precipitation and increased risk of flooding, while areas located far away from storm tracks are likely to experience less precipitation and increased risk of drought.
