Scientists say global warming – specifically the rapid warming of the Arctic – is a possible, if not likely, culprit in the extreme weather.
Freak cold in Texas has scientists discussing whether climate change is to
The freak cold spell that has killed at least 21 Americans and shut down power for days in Texas has revived scientific discussion over whether climate change could be delivering this week's chill.\u200b https://t.co/9iiVc0YKMm

“I think it’s a rock-solid case,” But “it might take a bit of time for the science to catch up and find all the details” to prove it. 🧐
The theory “remains speculative, and it is the reporting of it as fact that is not justified,” climate scientist Geoffrey Vallis at the Univ of Exeter tweeted on Tuesday. “It may be true, but perhaps more likely not.”
“It’s been unusual for a few weeks now – very, very crazy,” Francis said. “Totally topsy-turvy.”

Warming in the Arctic, with shrinking sea ice, is goosing the atmospheric wave in two places, giving it more energy when it strikes the polar vortex, making it more likely to disrupt the vortex, Cohen said.
From USA Today:
Some scientists – but not all – say there could be a connection between global warming and the wandering polar vortex: The theory is that when weird warmth invades the Arctic, some of the cold that's supposed to stay up there.
The wintry weather that has battered the southern US and parts of Europe could be a counterintuitive effect of the climate crisis

“We still have a lot to learn on this,” said Francis. “I think this year will be studied for a long time.”
The polar vortex, a weather pattern that originates in the Arctic, is increasingly descending to lower latitudes. Scientists say global warming caused by humans is partly responsible for shifts that bring glacial weather to more southern climes and keep it around longer.
Conditions became dire over the weekend in Texas, where an unprecedented wave of winter weather has crashed upon the typically warm state.

"It's hard to blame Texas for these outcomes. The state never assumed that it would experience such a widespread, ongoing cold spell, and its infrastructure simply was not built to withstand these types of temperatures."
But the sad fact is these weather events are becoming more and more common, and climate change is to thank.
Failure to act could result in Texas becoming a “snownado alley” — and that is a fate that the state’s infrastructure is not prepared to survive.
"Texas crisis is a wake-up call that exposes how the U.S. electric infrastructure may not be fully prepared to absorb steep climate-related spikes in demand for power."

"We are in a nonstationary world. Climate change means that it is not stationary," Craig said. "The last 40 years might not be reflective of what's coming down the pike the next 40 years."
Systems are designed to handle spikes in demand, but the wild and unpredictable weather linked to global warming will very likely push grids beyond their limits.
https://t.co/ZNATcRlSCn
"But as climate change accelerates, many electric grids will face extreme weather events that go far beyond the historical conditions those systems were designed for, putting them at risk of catastrophic failure."
Dr. Amy Butler, a research scientist at the NOAA Chemical Sciences Laboratory, has said that she has yet to find any long-term trend in polar vortex disruptions, which “occur naturally even in the absence of climate change.”
The sub-zero temperatures causing blackouts across the southern U.S. are connected to climate change.

As the planet warms and this contrast diminishes, the jet stream weakens and can no longer push large weather patterns out of the way. This is what caused wildfires above the Arctic Circle, droughts throughout the world, and record-setting heat waves from Moscow to the U.S.
While these events happen about six times per decade, according to the National Oceanic and Atmospheric Administration, Cohen maintains that climate change has increased the frequency with which the polar vortex weakens and allow the cold to air to run amok.
A winter storm caused Texas's power outage. Climate change likely caused the storm.
As the planet's climate changes, the only constant is unpredictability.

"The bad news is that the jet stream has been getting weaker over the last few years as the areas on both sides of it have gotten warmer." 👀
https://t.co/HGtY1vLUYJ
"There are waves in the jet stream and because of climate change and the warmer air in the Arctic and the largely ice-free Arctic sea, those waves are able to go far south"
Extreme winter storms aren’t inconsistent with global warming and will continue for decades, expert says.

THE MEANING, SIGNIFICANCE AND HISTORY OF SWASTIK
The Swastik is a geometrical figure and an ancient religious icon. Swastik has been Sanatan Dharma’s symbol of auspiciousness – mangalya since time immemorial.
The name swastika comes from Sanskrit (Devanagari: स्वस्तिक, pronounced: swastik) &denotes “conducive to wellbeing or auspicious”.
The word Swastik has a definite etymological origin in Sanskrit. It is derived from the roots su – meaning “well or auspicious” & as meaning “being”.
"सु अस्ति येन तत स्वस्तिकं"
Swastik is de symbol through which everything auspicios occurs
Scholars believe word’s origin in Vedas,known as Swasti mantra;
"🕉स्वस्ति ना इन्द्रो वृधश्रवाहा
स्वस्ति ना पूषा विश्ववेदाहा
स्वस्तिनास्तरक्ष्यो अरिश्तनेमिही
स्वस्तिनो बृहस्पतिर्दधातु"
It translates to," O famed Indra, redeem us. O Pusha, the beholder of all knowledge, redeem us. Redeem us O Garudji, of limitless speed and O Bruhaspati, redeem us".
SWASTIK’s COSMIC ORIGIN
The Swastika represents the living creation in the whole Cosmos.
Hindu astronomers divide the ecliptic circle of cosmos in 27 divisions called https://t.co/sLeuV1R2eQ this manner a cross forms in 4 directions in the celestial sky. At centre of this cross is Dhruva(Polestar). In a line from Dhruva, the stars known as Saptarishi can be observed.

I'm going to do two history threads on Ethiopia, one on its ancient history, one on its modern story (1800 to today). 🇪🇹
I'll begin with the ancient history ... and it goes way back. Because modern humans - and before that, the ancestors of humans - almost certainly originated in Ethiopia. 🇪🇹 (sub-thread):
The first likely historical reference to Ethiopia is ancient Egyptian records of trade expeditions to the "Land of Punt" in search of gold, ebony, ivory, incense, and wild animals, starting in c 2500 BC 🇪🇹
Ethiopians themselves believe that the Queen of Sheba, who visited Israel's King Solomon in the Bible (c 950 BC), came from Ethiopia (not Yemen, as others believe). Here she is meeting Solomon in a stain-glassed window in Addis Ababa's Holy Trinity Church. 🇪🇹
References to the Queen of Sheba are everywhere in Ethiopia. The national airline's frequent flier miles are even called "ShebaMiles". 🇪🇹
