Potty AOC makes a fool of herself again, blaming a tornado warning on climate change!
From the Independent:
Alexandria Ocasio-Cortez has used a tornado warning in Washington DC as an example of extreme weather in support of her demand for a more concerted effort to tackle the "climate crisis".
In a series of posts shared on Instagram, the Democratic congresswoman expressed concern over the weather, which she noted to her followers was not something the New York native was used to.
“Guys, they just issued a tornado watch in DC,” she said, before turning her camera to her staff, standing together in her office……
In a series of photos showing statistics, Ms Ocasio-Cortez urged her followers to focus on the fight against climate change.
“The climate crisis is real y’all,” she wrote in a text across her story, pointing to her proposed "Green New Deal" in the midst of the storm. “Guess we’re at casual tornadoes in growing regions of the country.”
Climate change is believed to be changing the courses and strength of tornadoes, moving deadlier ones to regions that previously faced lesser versions.
However, in Thursday’s case, the tornado did not ultimately strike DC, touching down in nearby Maryland county instead.
There is nothing unusual about tornadoes in that part of the world. In Maryland, for instance, there are on average eight tornadoes every year.

Indeed, on a area basis, Maryland is one of the most tornado prone states, even more than Oklahoma:

You may have noticed the Independent’s reference in the penultimate paragraph:
Climate change is believed to be changing the courses and strength of tornadoes, moving deadlier ones to regions that previously faced lesser versions.
This links to a thoroughly deceitful piece from PBS in March:
When Americans hear the word tornado, their minds may bolt to huge twisters rolling across northern Texas, Oklahoma, Nebraska and Kansas, like a scene out of “The Wizard of Oz.”
But the deadliest U.S tornado in six years didn’t strike the Great Plains — instead, it touched down Sunday hundreds of miles away in Alabama and Georgia. On Monday and Tuesday, search crews, aided by dogs and drones, sifted through wreckage caused by the violent tornado, which blew across 30 miles with winds reaching up to 170 miles per hour. So far, the storm has killed 23 people, including three children, and dozens remain missing.
While this weekend’s storms took the Southeast by surprise, the events fit into a growing trend for a region meteorologists now call Dixie Alley. Since the turn of the millennium, the Dixie Alley has witnessed an ever-increasing onslaught of tornadoes.
Rather than lie squarely in the Great Plains, America’s tornadoes appear to be sliding into the Midwest and Southeast.
“Whether this is climate change or not, what all the studies have shown is that this particular part of the U.S. has been having more tornado activity and more tornado outbreaks than it has had in decades before,” said Mike Tippett, a Columbia University applied mathematician who studies the climate.
Tippett is among a group of scientists trying to dissect why the South has become a hotbed for tornadoes and severe thunderstorms.
Some signs point to human-made climate change, but those conclusions are mixed at best. Weather and climate scientists have confidence, for instance, in the parallels between tornadoes creeping east and global warming — but are less convinced that climate change is increasing the number of tornadoes overall.
Most of all, their research highlights the barriers in forecasting that keep us from predicting where and when tornadoes might strike.

I came across the study at the time, and exposed it as totally corrupt here. In essence, the study looked at the total number of tornadoes hitting the Southeast.
As I pointed out, and as any tornado expert would have told the authors, many more tornadoes are reported nowadays, purely because of better technology, such as Doppler, and more comprehensive reporting practices.
This all results in many more weaker tornadoes getting reported, which would have gone under the radar in the 1970s and 80s. It is this factor which has produced Tippet’s supposed “increasing onslaught of tornadoes”.
It is actually a myth that tornadoes are a rare event in Dixie Alley. As NOAA show, based on 1985-2015 climatology, that part of the country is actually the hot spot for the strongest EF-4+ tornadoes.

However, AOC is right about one thing, climate change is having an effect on tornadoes. It is actually making them less common, especially the violent ones:
