South Pole warming three times faster than rest of Earth: study

Published

on

The South Pole has warmed three times faster than the rest of the planet in the last 30 years due to warmer tropical ocean temperatures, new research showed Monday.

Antarctica’s temperature varies widely according to season and region, and for years it had been thought that the South Pole had stayed cool even as the continent heated up.

Researchers in New Zealand, Britain and the United States analyzed 60 years of weather station data and used computer modeling to show what was causing the accelerated warming.

They found that warmer ocean temperatures in the western Pacific had over the decades lowered atmospheric pressure over the Weddell Sea in the southern Atlantic.

This in turn had increased the flow of warm air directly over the South Pole — warming it by more than 1.83C (about 3.3F) since 1989.

Authors of the research said the natural warming trend was likely boosted by manmade greenhouse gas emissions and could be masking the heating effect of carbon pollution over the South Pole.

“While temperatures were known to be warming across West Antarctica and the Antarctic Peninsula during the 20th century, the South Pole was cooling,” said Kyle Clem, a researcher at Victoria University of Wellington, and lead study author.

“It was suspected that this part of Antarctica… might be immune to/isolated from warming. We found this is not the case any more,” he told AFP.

The data showed that the South Pole — the most remote spot on Earth — was now warming at a rate of around 0.6C (1.1F) a decade, compared with around 0.2C (1.4F) for the rest of the planet.

The authors of the study, published in the Nature Climate Change journal, attributed the change to a phenomenon known as the Interdecadal Pacific Oscillation (IPO).

The IPO cycle lasts roughly 15-30 years, and alternates between a “positive” state — in which the tropical Pacific is hotter and the northern Pacific is colder than average — and a “negative” state where the temperature anomaly is reversed.

The IPO flipped to a negative cycle at the start of the century, driving greater convection and more pressure extremes at high latitudes, leading to a strong flow of warmer air right over the South Pole.

Clem said that the 1.83C (3.3F) level of warming exceeded 99.99 percent of all modeled 30-year warming trends.

“While the warming was just within the natural variability of climate models, it was highly likely human activity had contributed,” he said.

Montana GOP ticket sidelined after exposure to COVID-positive Trump, Jr. girlfriend Kimberly Guilfoyle: report

Published

on

The Montana Republican Party is facing a crisis after multiple members of the ticket traveled to South Dakota for Donald Trump's rally and were potentially exposed to COVID-19.

"Montana gubernatorial candidate Rep. Greg Gianforte and his running mate, Kristen Juras, confirmed Saturday they will self-quarantine after Gianforte's wife, Susan, and Juras attended an event last week with Kimberly Guilfoyle, who has since tested positive for COVID-19," KBZK-TV reported Saturday.

‘Perhaps the most un-American speech ever delivered by an American president’: Ambassador McFaul

Published

on

President Donald Trump's address at Mount Rushmore was blasted as "un-American" by former U.S. Ambassador to Russia Michael McFaul.

McFaul retweeted a clip of the leader of the free world failing to pronounce the word, "totalitarianism."

"Trump has no idea what words like fascism and totalitarianism mean," McFaul, now a professor at Stanford, declared.

"To those who wrote this speech and those senior [White House] officials who approved this speech, shame on you. Perhaps the most un-American speech ever delivered by an American president and on the July 4th weekend no less," he explained.

WATCH: MSNBC reporter cuts off Arizona Trump fan as he goes on rant about Antifa and killing Black babies

Published

on

On Saturday, MSNBC reporter Vaughn Hillyard interviewed "Ted," a pro-Trump protester in Prescott, Arizona — and was promptly forced to cut him off as the conversation went off the rails.

"What leads you here today?" asked Hillyard. "And does the lack of masks, including on your part—"

"Well, we're here to support President Trump and the Republican ticket," said Ted. "This is our protest against all the other protests that have been going on in the country trying to take our nation down."

"Are you concerned about the pandemic?" said Hillyard.

"No, we support our police department in Prescott, and we do not support Antifa, which is a communist organization just like BLM," said Ted. "If you listen to the founders of BLM, they're communists. If they cared about Black lives really, they would think about the million abortions of Black babies, and they would think about the thousands of young Black men that are killed in the inner city, but they don't. It's an anti-police organization and Antifa is just as bad. If you notice—"
