By now, we all realize that long-range weather forecasting -- models that forecast beyond the next 3 days -- can be as useful as a gas tank in a Tesla, but there is increasing confidence that a major snowstorm is taking shape over parts of Colorado, Wyoming, and Nebraska this coming weekend.

The models have been consistently showing for the last few days areas of snow accumulation over 40 inches in some places up and down the front range along Interstate 25.Early this week, forecast models were hinting at possibly even 5 feet of snow. The National Weather Service in Boulder was quick to point out it wasn't forecasting these totals. After a lengthy discussion on the possibilities in the forecast this morning "the messaging of 1 to 3 feet of snow for much of our forecast area is still on track," the NWS Boulder said.

Is it time to panic? No.Is it time to prepare for a possible 3-foot snowstorm? Yes.

A major winter storm system is expected to wallop parts of the United States with heavy snow and rain over the Martin Luther King Jr. holiday weekend, meteorologists have warned.

The upper and the middle Mississippi Valley could get heavy snow Friday, with potentially freezing rain set to fall over parts of the Carolinas and the southern Appalachians this weekend, according to the National Weather Service.

“The snow will result in reduced visibility and hazardous driving conditions,” it said. The system is already prod

A record-breaking snowfall in Newfoundland, Canada, has left residents with the enormous task of digging themselves out of piles and piles of snow.St. John's International Airport recorded 76.2 cm (30 inches) of snow Friday, according to Environment Canada, breaking the previous daily snowfall record set on April 5, 1999, of 68.4 cm (26.93 inches).

Of course it's not a laughing matter for everyone. A state of emergency remained in effect for parts of the province of Newfoundland and Labrador on Sunday morning, including St. John's and Paradise. St. John's officials still wanted people to stay off the roads, but lifted some restrictions Sunday morning, allowing gas stations to open and pharmacies to open from noon until 7 pm.

More snow is on the way, CNN meteorologist Allison Chinchar said. It was snowing in Nova Scotia, Prince Edward Island and New Brunswick on Sunday morning, but that system was expected to move east into Newfoundland and Labrador Sunday evening and into the overnight hours.

“There is no reason to think that in 30 years much of anything will be as it is today,” one of the editors of a new report on the Arctic climate said.

The Arctic continued its unwavering shift toward a new climate in 2020, as the effects of near-record warming surged across the region, shrinking ice and snow cover and fueling extreme wildfires, scientists said Tuesday in an annual assessment of the region.

This year the minimum extent of sea ice in the Arctic Ocean, reached at the end of the melt season in September, was the second-lowest in the satellite record, the scientists reported

New research on the connection between climate change and winter drownings has found that reported drowning deaths are increasing exponentially in areas with warmer winters.

Some of the sharpest increases were in areas where Indigenous customs and livelihood require extended time on ice. Across the countries studied, children under the age of 9 and teenagers and adults between 15 and 39 were the most vulnerable to winter drowning accidents.

“I think there’s a disconnect between climate change and the local, everyday impacts,” Dr. Sharma said. “If you think about climate change in winter, you’re thinking about polar bears and ice sheets, but not about these activities that are just ingrained in our culture.

Study Finds Snowpack in California’s Sierra Nevada to Be Lowest in 500 Years

After analyzing the data, the team determined with its model that snowpack levels as low as this year’s were a once-in-1,000-years event. But because of rising temperatures caused by human activities, the researchers said they thought that snow droughts would become much more frequent.

Most forecasts have failed to predict these colder winters, however, because the primary drivers in their models are the oceans, which have been warming even as winters have grown chillier. They have ignored the snow in Siberia.

The show, after all, is airing in an environment—its audiences’ own version of the Known World—that is itself being steadily shaped by lies. The leader who misleads with impunity, weaponizing lies as an easy means to uneasy ends. The system that allows him to do it, because the illusions often suit the purposes of the powerful. The wheel that, refusing to break, spins on through the dullness of inertia. The looming threat, totalizing and existential, dismissed as a fantasy; the war against it that will be fought with too few resources and insufficient conviction; the world that will be knocked off its axis by untruths molded into myths.

: America's north-east braced for record May cold

The north-eastern US is about to get a cold spring farewell from winter’s bad boy, the polar vortex, which could bring rare May snowfall and record-low temperatures to some areas over the Mother’s Day weekend, forecasters say.

Around this time of year, the polar vortex usually breaks up, but this breakup is a bit different, said Judah Cohen, a winter storm expert for Atmospheric Environmental Research, a commercial firm outside Boston.

But history shows that past pandemics have reshaped societies in profound ways. Hundreds of millions of people have died. Empires have fallen. Governments have cracked. Generations have been annihilated. Here is a look at how pandemics have remade the world.

Many historians trace the fall of the Roman empire back to the Antonine Plague, which swept Rome during the reign of Marcus Aurelius. Nobody has ever nailed down the exact cause, but symptoms recorded by a physician named Galen — gruesome skin sores, high fever, diarrhea and sore throats — strongly suggest it was smallpox and measles.

Thought to be the world’s first episode of bubonic plague, its namesake was the Byzantine emperor who was in power when it hit, likely arriving in the form of infected fleas hitching rides across the world on the backs of rodents.

As Malcolm Forbes Baldwin, the acting chairman of the president’s Council for Environmental Quality, told industry executives in 1981, “There can be no more important or conservative concern than the protection of the globe itself.”

Among those who called for urgent, immediate and far-reaching climate policy were Senators John Chafee, Robert Stafford and David Durenberger; the E.P.A. administrator, William K. Reilly; and, during his campaign for president, George H.W. Bush.

It was understood that action would have to come immediately. At the start of the 1980s, scientists within the federal government predicted that conclusive evidence of warming would appear on the global temperature record by the end of the decade, at which point it would be too late to avoid disaster.

As human civilizations flourished, so did infectious disease. Large numbers of people living in close proximity to each other and to animals, often with poor sanitation and nutrition, provided fertile breeding grounds for disease. And new overseas trading routes spread the novel infections far and wide, creating the first global pandemics.

The plague decimated Constantinople and spread like wildfire across Europe, Asia, North Africa and Arabia killing an estimated 30 to 50 million people, perhaps half of the world’s population. “People had no real understanding of how to fight it other than trying to avoid sick people,” says Thomas Mockaitis, a history professor at DePaul University. “As to how the plague ended, the best guess is that the majority of people in a pandemic somehow survive, and those who survive have immunity.”

As for how to stop the disease, people still had no scientific understanding of contagion, says Mockaitis, but they knew that it had something to do with proximity. That’s why forward-thinking officials in Venetian-controlled port city of Ragusa decided to keep newly arrived sailors in isolation until they could prove they weren’t sick.

(CNN) — China has revealed a prototype for a new high-speed Maglev train that is capable of reaching speeds of 620 kilometers (385 miles) per hour.

The train runs on high-temperature superconducting (HTS) power that makes it look as if the train is floating along the magnetized tracks.

The sleek 21-meter-long (69 feet) prototype was unveiled to media in the city of Chengdu, Sichuan Province, on January 13. In addition, university researchers constructed 165 meters (541 feet) of track to demonstrate how the train would look and feel in transit, according to state-run Xinhua News.

The human species Homo erectus evolved out of earlier human forms 1.8 million years ago and survived until 143,000 years ago. He and she walked on two feet and used tools and gradually spread over Africa and western and eastern Asia. Out of Homo erectus evolved, it is thought, Homo heidelbergensis. This common ancestor of both Homo neanderthalensis and Homo sapiens existed from 400,000 to 350,000 years ago. Homo heidelbergensis used fire and was the first to build shelters as opposed to just finding shelter, although they did that too. The European branch of Homo heidelbergensis evolved into the Neandertals 300,000 or more years ago. The Neandertals were big-bodied, light-skinned, cold-adapted humans. Some, at least, were redheads. The African branch of Homo heidelbergensis evolved into Homo sapiens—us—200,000 years ago. We were slighter-bodied. We had narrower hips and darker skin

Homo sapiens began moving out of Africa to the Near East 40,000 years ago. There they encountered a southern remnant of Neandertals. Most of that species had long since gone extinct. But we shared the region for 15,000 years, until the Neandertals disappeared.

Contrary to previous suppositions and speculations, Neandertals ate a varied diet including not only large mammals like mammoths but also birds, rabbits, and seafood. They possessed the “language gene,” just as we do, and likely communicated in some sort of language. They manufactured tools, although not in as great a variety as we did. They decorated their bodies and wore jewelry—an index of symbolic cognition. They likely adorned themselves with feathers.

Hardship has long been common here — and still is. But in just four years, the country has gone from the European Union’s worst economic disaster zone to a model of what the International Monetary Fund hails as the healing properties of deep budget cuts. Latvia’s economy, after shriveling by more than 20 percent from its peak, grew by about 5 percent last year, making it the best performer in the 27-nation European Union. Its budget deficit is down sharply and exports are soaring.

Now its abrupt turn for the better has put a spotlight on a ticklish question for those who look to orthodox economics for a solution to Europe’s wider economic woes: Instead of obeying any universal laws of economic gravity, do different people respond differently to the same forces?

in Latvia, where the government laid off a third of its civil servants, slashed wages for the rest and sharply reduced support for hospitals, people mostly accepted the bitter medicine. Prime Minister Valdis Dombrovskis, who presided over the austerity, was re-elected, not thrown out of office, as many of his counterparts elsewhere have been. The cuts calmed fears on financial markets that the country was about to go bankrupt, and this meant that the government and private companies could again get the loans they needed to stay afloat. At the same time, private businesses followed the government in slashing wages, which made the country’s labor force more competitive by reducing the prices of its goods. As exports grew, companies began to rehire workers.

A half-century ago in his famous "Two Cultures" speech, C.P. Snow defined the growing rift between the world of scientists (including, increasingly, the commercial world) and that of literary intellectuals (including, increasingly, the humanities).

Today, the "two cultures" not only rarely speak to one another, but also increasingly, as their languages and world views diverge, are unable to do so.

Science merely nods and says, "I see your Jane Austen monographs and deconstructions of 'The Tempest' and raise you stem-cell research and the iPhone"

the National Snow and Ice Data Center, in Boulder, Colorado, announced that the Arctic sea ice had reached a new low. The sea ice shrinks in the summer and grows again during winter’s long polar night. It usually reaches its minimum extent in mid-September. On September 16, 2012, the N.S.I.D.C. reported, the sea ice covered 1.3 million square miles. This was just half of its average extent during the nineteen-eighties and nineties, and nearly twenty per cent less than its extent in 2007, the previous record-low year.

It would be difficult to overstate the significance of this development. We are now seeing changes occur in a matter of years that, in the normal geological scheme of things, should take thousands, even millions of times longer than that. On the basis of the 2012 melt season, one of the world’s leading experts on the Arctic ice cap, Peter Wadhams, of Cambridge University, has predicted that the Arctic Ocean will be entirely ice-free in summer by 2016. Since open water absorbs sunlight, while ice tends to reflect it, this will accelerate global warming. Meanwhile, recent research suggests that the melting of the Arctic ice cap will have, and indeed is probably already having, a profound effect on the U.S. and Europe, making extreme weather events much more likely. As Jennifer Francis, a scientist at Rutgers, observed recently in a conference call with reporters, the loss of sea ice changes the dynamics of the entire system: “It’s like having a new energy source for the atmosphere.”

You might have thought that with the Arctic melting, the U.S. in the midst of what will almost certainly be the warmest year on record, and more than sixty per cent of the lower forty-eight states experiencing “moderate to exceptional” drought, at least one of the candidates would feel compelled to speak out about the issue. If that’s the case, though, you probably live in a different country.
