Extreme winter weather becoming more common as Arctic warms, study finds

By
The sort of severe winter weather that has rattled parts of the US and UK is becoming more common as the Arctic warms, with scientists finding a strong link between high temperatures near the pole and unusually heavy snowfall and frigid weather further south.

A sharp increase in temperatures across the Arctic since the early 1990s has coincided with an uptick in abnormally cold snaps in winter, particularly in the eastern US, according to new research that analyzed temperature data from 1950 onwards.

Extreme cold winter weather is up to four times more likely when temperatures in the Arctic are unusually high, the study found. Researchers compared daily temperatures from across the Arctic region with something called the accumulated winter season severity index, which grades winter weather based on temperature, snow fall and snow depth, across 12 US cities.

“There’s a remarkably strong correlation between a warm Arctic and cold winter weather further south,” said Judah Cohen, a climatologist at Atmospheric and Environmental Research. “It’s a complex story – global warming is contributing to milder temperatures but is also having unforeseen consequences such as this.”

Russia 'on wrong side of history' over Syria chemical weapons – US

By
A top US disarmament official has accused Russia of being on the wrong side of history on chemical weapon use in Syria, after reports of a chlorine attack in the besieged enclave of eastern Ghouta and the leaking of a UN reportinto the supply of related items from North Korea. The world’s chemical weapons watchdog is said to have opened an investigation into the latest reports of chemical attacks in Ghouta, where doctors said more than a dozen civilians had been treated for symptoms that matched those of exposure to chlorine gas.The investigation also comes a day after details of a UN report were leaked, which said North Korea had sent Syria more than 40 items used in ballistic and chemical weapons programmes in the five years from 2012 to 2017. Bashar al-Assad’s government was supposed to have given up its chemical weapons arsenal under a deal brokered in 2013 between the US and Russia, but the agreement does not include chlorine because of its industrial uses.

A life in science: Stephen Hawking

By
Stephen Hawking always had something to say. He shook up the world of cosmology with more than 150 papers, dozens of which became renowned. He was told he had only a brief time on Earth, but spent half a century captivating audiences in lecture halls, on TV and in the pages of his books. For newspaper editors, almost any utterance of his could make a headline, and he knew it. Hawking warned about the threats of nuclear war, genetically modified viruses, artificial intelligence and marauding aliens. He pronounced on the human condition and once dismissed the role of God in creating the universe. The statement caused a fuss, as the denial of invisible superbeings still can in the 21st century. It is an unwritten law of nature that when a personality steps into the foreground, their work must take a step back. In Hawking’s case, being the most famous scientist of our time had a mysterious ability to eclipse his actual achievements. At his best Hawking was spectacular: he made intuitive le...

What to know as Billy Graham becomes fourth citizen to 'lie in honor' at US Capitol

By
There are few distinctions in Congress as high as the one afforded the late Rev. Billy Graham at the U.S. Capitol Wednesday and Thursday. Graham will “lie in honor” in the Capitol Rotunda. Note that Graham will “lie in honor,” not “in state.” We should refer to Graham as “lying in honor” rather than “lying in state.” There is little which distinguishes someone from “lying in honor” rather that in “state.” Officially, “lying in honor” is one step below “lying in state.” The pomp and circumstance is much the same. But it formally is one level below “state.” The Capitol Rotunda is considered to be the the most “holy” place in the American political experience. That’s why Congress reserves such ceremonies in the Rotunda for some of the country’s most-eminent citizens. Source :- foxnews
