Cold weather spurs climate conversation

The Ark-La-Texas region could experience record cold temperatures tonight.

The wintry weather that has locked much of the Midwest and Northeast in an icy grip is being felt in Texas, as well. Some areas in East Texas could experience record low temperatures tonight, when temperatures are forecast to dip into the mid-teens.

As Central and South Texas see cold snaps (and brace for another possible wintry mix of ice and snow this week), climate change skeptics have taken to Twitter to express their disbelief:



Despite the dropping temperatures and extreme cold weather events like the Polar Vortex earlier this month, the science hasn’t changed on global warming. As University of Texas at Austin atmospheric scientist Dr. Ned Vizy says that more extreme cold snaps are actually a predictable symptom of an warming climate.

“Over the past decade or so, you’re seeing a greater occurrence of these extreme events such as cold snaps, the tornado outbreak up in Oklahoma, the droughts,” he says. ”In reality, this is what you’d expect to see under a warmer climate state.”

Vizy’s work at UT’s Department of Geological Sciences focuses on the relationship between extreme weather events and climate change.

“You’re seeing signs of climate change that many scientists have identified and are continuing to work to better understand,” he said of recent extreme weather.

According to the National Oceanic and Atmospheric Administration (NOAA), 2013 was the fourth warmest year since 1880, when globally-averaged temperatures were first recorded. At the same time, December was the 21st coldest on record for the United States and the coldest December since 2009.

“You can’t assign, for the entire globe, one set outcome,” Vizy says. “There’s a lot of smaller-scale structure that you have to understand, but in terms of an overall temperature pattern, globally, you’re going to see a warming. The regional implications of that vary quite a bit.”  


Snow in Austin in January isn’t a sign that climate scientists are wrong about rising global temperatures, so why are many people quick to dismiss global warming when the temperature dips below freezing?

“Most people are most familiar with weather, because that’s what you see everyday,” Vizy says. “Climate is on a longer timescale; you’re looking over decades to centuries to try to understand climate.”

Though the tweets can be read in jest, Vizy says it’s no laughing matter. Misinformation about the effects of climate change—and what a cold snap actually means—can be particularly dangerous while trying to plan for the future.

“Swaying the public opinion is very important in the U.S. You see that all the time,” he says. “Climate change is no different than that. If you have a lot of naysayers, it’ll sway what actions get done or what funding resources are allocated.”
