Atlantic currents have seen ‘drastic’ changes: study

Published

on

Scientists have found evidence of a “drastic” shift since the 1970s in north Atlantic Ocean currents that usually influence weather in the northern hemisphere, Swiss researchers said on Tuesday.

The team of biochemists and oceanographers from Switzerland, Canada and the United States detected changes in deep sea Atlantic corals that indicated the declining influence of the cold northern Labrador Current.

They said in the US National Academy of Science journal PNAS that the change “since the early 1970s is largely unique in the context of the last approximately 1,800 years,” and raised the prospect of a direct link with global warming.

The Labrador Current interacts with the warmer Gulfstream from the south.

They in turn have a complex interaction with a climate pattern, the North Atlantic Oscillation, which has a dominant impact on weather in Europe and North America.

Scientists have pointed to a disruption or shifts in the oscillation as an explanation for moist or harsh winters in Europe, or severe summer droughts such as in Russia, in recent years.

One of the five scientists, Carsten Schubert, of the Swiss Federal Institute of Acquatic Sciences and Technology (EAWAG), underlined that for nearly 2,000 years the sub polar Labrador current off northern Canada and Newfoundland was the dominant force.

However that pattern appeared to have only been repeated occasionally in recent decades.

“Now the southern current has taken over, it’s really a drastic change,” Schubert told AFP, pointing to the evidence of the shift towards warmer water in the northwest Atlantic.

The research was based on nitrogen isotope signatures in 700 year old coral reefs on the ocean floor, which feed on sinking organic particles.

While water pushed by the Gulfstream is salty and rich in nutrients, the colder Arctic waters carried by the Labrador current contain fewer nutrients.

Changes could be dated because of the natural growth rings seen in corals.

“The researchers suspect there is a direct connection between the changes in oceanic currents in the North Atlantic and global warming caused by human activities,” said EAWAG in a statement.

Stephen Colbert rips ‘idiot’ GOP senator for defending Trump’s unconstitutional self-dealing

Published

on

"Late Show" host Stephen Colbert returned from New Zealand for a new show that aired Monday evening.

"I have been as far from the insatiable black hole of news that is Donald Trump as you can get on this planet.

I've heard there have been some developments over the last 10 days that did not go well for Donnie,"

The host ripped Trump's 71-minute press conference.

"Seventy-one minutes is not a press conference, it's a one man show," he explained. "If you liked 'Fleabag,' you'll love Donald Trump in 'Douchebag,'" he said.

Texas Republicans are abandoning the state’s GOP Speaker: ‘We no longer support him’

Published

on

Some of the most powerful Texas House Republicans said Monday they no longer support GOP Speaker Dennis Bonnen, marking the biggest blow yet to his political future amid the fallout from a secret recording released last week by a hardline conservative activist.

Five Republicans considered senior members of the lower chamber issued a statement withdrawing support for him: State Reps. Four Price of Amarillo, Dan Huberty of Houston, Lyle Larson of San Antonio, Chris Paddie of Marshall and John Frullo of Lubbock.

Donald Trump is making a mockery of Marco Rubio — and the Florida senator is letting him

Published

on

Sen. Marco Rubio was once one of Donald Trump’s most formidable opponents; now, the Florida senator bends over backward to excuse the president’s corruption.

In 2016, Rubio and Trump sparred frequently on the Republican primary debate stage. Trump picked the uninspired nickname “Little Marco” for the senator, which didn’t seem to do much damage on its own, but Rubio never gained the momentum or strength that his backers hoped would prove to be strong enough to take down the reality TV candidate. As Rubio grew desperate, he launched one of his most memorable and pitiful attacks by stooping to his opponent’s level, implying that Trump had a small penis. It was more of an embarrassing moment for Rubio than anyone else, though Trump helped himself with a crude rejoinder.
