‘Mini Ice Age’ on the way in 15 years, say scientists

Published

on

A study by researchers at Great Britain’s Northumbria University say that competing physical cycles within our sun will cancel each other out in the next solar cycle, resulting in a “mini Ice Age” like one that gripped the Northern Hemisphere from 1645 to 1715.

According to the Telegraph, a team of solar researchers led by Professor Valentina Zharkova say that they have cracked a riddle that has long puzzled scientists and enabled them to predict solar activity with 97 percent accuracy.

In a meeting of the National Astronomy Meeting in Llandudno, Zharkova said two dynamic fluid plumes within the sun will be working in opposite hemispheres, effectively canceling each other out and bringing about a rare period of extremely low solar activity.

“[In the cycle between 2030 and around 2040] the two waves exactly mirror each other — peaking at the same time but in opposite hemispheres of the sun,” she explained.

“Their interaction will be disruptive, or they will nearly cancel each other,” she said. “We predict that this will lead to the properties of a ‘Maunder minimum.'”

The Maunder Minimum is the 70-year period from 1645 to 1715 when North America and Europe experienced very cold winters due to lower solar temperatures and minimal sunspot activity.

“In England during this “Little Ice Age,'” wrote the Telegraph’s Dan Hyde, “River Thames frost fairs were held. In the winter of 1683-84 the Thames froze over for seven weeks, during which it was ‘passable by foot,’ according to historical records.”

Zharkova said that scientists have long known of one convecting dynamo of fluid deep within the sun, but have found its cycles and movements difficult to predict.

However, the Northumbria team have discovered a second fluid plume that interacts with the first.

“We found magnetic wave components appearing in pairs, originating in two different layers in the sun’s interior,” she said.

The two fluid dynamos operate in eleven year cycles, although these cycles fluctuate in length and intensity. By calculating the effect the two systems have on each other, the team has reportedly been able to sharpen the accuracy of their predictions for solar activity.

“Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity,” Zharkova said, producing hotter weather and a higher number of solar flares and other events.

“When they are out of phase,” she went on, “we have solar minimums. When there is full phase separation, we have the conditions last seen during the Maunder minimum, 370 years ago.”

Trump attacks the homeless for sleeping in ‘our best highways, our best streets’ and vows to ‘do something about it’

Published

President Donald Trump on Tuesday issued an angry broadside against America's homeless population.

The Washington Post's Josh Dawsey reports that Trump, during a conversation with reporters, complained that homeless people are living in "our best highways, our best streets, our best entrances to buildings."

The president then said that people who live in these buildings pay "tremendous taxes" and want "prestige," and then vowed that "we'll be doing something about it."

Trump says homeless people are living in "our best highways, our best streets, our best entrances to buildings" where people pay "tremendous taxes" and want "prestige." Says he's speaking to tenants who "want to leave the country." He adds: "We'll be doing something about it."

‘SLAP CUFFS ON HIM NOW’: Internet hammers House Dems for treating Corey Lewandowski with kid gloves

Published

on

Trump loyalist Corey Lewandowski testified before the House Judiciary Committee on Tuesday and it quickly devolved into a circus in which the former Trump campaign manager refused to answer basic questions from Democrats.

During the hearing, the House Judiciary Democrats sent out a tweet accusing the White House of orchestrating a coverup of the president's actions as outlined by special counsel Robert Mueller's report on Russian interference in the 2016 presidential election.

However, many Twitter users went on to hammer the Democrats for purportedly treating the constantly obfuscating and stalling Lewandowski with kid gloves.

Journalist Cokie Roberts died on Tuesday and President Donald Trump didn't hesitate to make her passing all about himself.

Per CNN's Daniel Dale, Trump was asked by reporters if he had a comment about Roberts' death at the age of 75 this week, and he responded by complaining that she didn't give him favorable coverage.

"I never met her," the president replied. "She never treated me nicely. But I would like to wish her family well. She was a professional and I respect professionals... never treated me well, but I certainly respect her as a professional."

Per pool, here's Trump on the death of Cokie Roberts: “I never met her. She never treated me nicely. But I would like to wish her family well. She was a professional and I respect professionals...Never treated me well, but I certainly respect her as a professional.”
