The climate cultists just refuse to give up on their talking point. They came up with a theory, then created data to match it, rather than coming up with a hypothesis and gathering data, testing, reassessing, that whole Scientific Method thing
Study: Warmer Arctic led to killer cold in Texas, much of US
Warming of the Arctic caused by climate change has increased the number of polar vortex outbreaks, when frigid air from the far north bathes the central and eastern United States in killer cold, a study finds.
The study in the journal Science Thursday is the first to show the connections between changes in the polar region and February’s Valentine’s Week freeze that triggered widespread power outages in Texas, killing more than 170 people and causing at least $20 billion in damage.
The polar vortex normally keeps icy air trapped in the Arctic. But warmer air weakens the vortex, allowing it to stretch and wander south. The number of times it has weakened per year has more than doubled since the early 1980s, said study lead author Judah Cohen, a winter storm expert for Atmospheric Environmental Research, a commercial firm outside of Boston.
“It is counterintuitive that a rapidly warming Arctic can lead to an increase in extreme cold in a place as far south as Texas, but the lesson from our analysis is to expect the unexpected with climate change,†Cohen said.
Even if true, it still wouldn’t settle the actual debate, which is over causation. Hey, it could be true, but, what if the warming climate is mostly natural, just like during multiple warm periods since the end of the glacial age 20,000 years ago? Wouldn’t this mean that all the massive warm snaps are caused by a very cold Arctic? Has this been tested in the Southern Hemisphere? From the study
Anthropogenic global warming is projected to increase some weather extremes—for example, more heat waves and heavy precipitation events (1, 2)—but not severe winter weather such as cold air outbreaks and heavy snowfalls (3, 4). Yet, contrary to global climate model (GCM) projections, recent weather extremes have included an increase in cold air outbreaks and/or heavy snowfalls across the Northern Hemisphere (NH) since 1990 up to the recent past (3, 5–8). The most recent example of extreme winter weather was the anomalous cold weather of January and February 2021 in Asia (9), Europe (10, 11), and especially the United States (US).
So, they began with the belief that this was all caused by Mankind, hence, a doomsday cult study, nothing more, nothing less. They also incorporated a slew of previous computer model studies to get to their endpoint. And more of their own computer models. Pure junk science.
