Most Arctic sea ice ‘gone in decade’

Published

on

LONDON — The Arctic ice cap will disappear completely in summer months within 20 to 30 years, a polar research team said as they presented findings from an expedition led by adventurer Pen Hadow.

It is likely to be largely ice-free during the warmer months within a decade, the experts added.

Veteran polar explorer Hadow and two other Britons went out on the Arctic ice cap for 73 days during the northern spring, taking more than 6,000 measurements and observations of the sea ice.

The raw data they collected from March to May has been analysed, producing some stark predictions about the state of the ice cap.

“The summer ice cover will completely vanish in 20 to 30 years but in less than that it will have considerably retreated,” said Professor Peter Wadhams, head of the polar ocean physics group at Britain’s prestigious Cambridge University.

“In about 10 years, the Arctic ice will be considered as open sea.”

Starting off from northern Canada, Hadow, Martin Hartley and Ann Daniels skied over the ice cap to measure the thickness of the remaining ice, assessing its density and the depth of overlying snow, as well as taking weather and sea temperature readings.

Across their 450-kilometre (290 mile) route, the average thickness of the ice floes was 1.8 metres (six feet), while it was 4.8 metres when incorporating the compressed ridges of ice.

“An average thickness of 1.8 metres is typical of first year ice, which is more vulnerable in the summer. And the multi-year ice is shrinking back more rapidly,” said Wadhams.

“It’s a concrete example of global change in action.

“With a larger part of the region now in first year ice, it is clearly more vulnerable. The area is now more likely to become open water each summer, bringing forward the potential date when the summer sea ice will be completely gone.”

Doctor Martin Sommerkorn, senior climate change adviser for the World Wide Fund for Nature’s international Arctic programme, said the survey painted a sombre picture of the ice meltdown, which was happening “faster than we thought”.

“Remove the Arctic ice cap and we are left with a very different and much warmer world,” he said.

Loss of sea ice cover will “set in motion powerful climate feedbacks which will have an impact far beyond the Arctic itself,” he added.

“This could lead to flooding affecting one quarter of the world’s population, substantial increases in greenhouse gas emission from massive carbon pools and extreme global weather changes.”

“Today’s findings provide yet another urgent call for action to world leaders ahead of the United Nations climate summit in Copenhagen in December to rapidly and effectively curb global greenhouse gas emissions.”

Trump felt free to ask for Ukraine election interference after Mueller let him off the hook: CNN guest

Published

on

On CNN's "New Day Weekend," author and commentator Garrett Graff noted that President Donald Trump's attempt to push Ukraine to investigate former Vice President Joe Biden came right after former special counsel Robert Mueller's investigation of Russian interference in 2016 ended — and suggested the two were related.

"You know, Garrett, there may be some people thinking 'Gosh, we just got out of the whole scenario with the Mueller report. Now we have this again,'" said anchor Christi Paul. "Do you get a sense that there are people looking at this saying 'I think I have confidence in the 2020 election?'"

Alexander von Humboldt was the first person to understand climate change — more than 200 years ago

Published

on

Alexander von Humboldt was born on September 14, 1769. In his day, he was a globetrotting, convention-defying hero— one of the first recorded individuals to raise environmental concerns. To make him hip for a new generation, all it takes is a rediscovery of Humboldt by the young climate strikers across the globe. Their numbers are growing, their task is huge, and they are now urging adults to join them. Why let parents fiddle when the house burns? On May 22, grown-ups at the Columbia Journalism Review, The Nation, and The Guardian listened and launched Covering Climate Now, a project to encourage more coverage of climate change in the media. Bill Moyers, the keynote speaker, pointed out that from 2017 to 2018, major network coverage of climate issues fell 45 percent to a total of a mere 142 minutes. And on May 23, with her knack of being spot-on, 16-year-old climate activist and rising star Greta Thunberg promptly wrote of taking on the climate change challenge: “It’s humanity’s job.”

Cory Booker planning to suspend his campaign if his fundraising does not improve: report

Published

on

On Saturday, NBC News reported that Sen. Cory Booker (D-NJ) has released a campaign memo indicating he will exit the Democratic presidential primary if he is unable to raise millions of dollars within days.

"Without a fundraising surge to close out this quarter, we do not see a legitimate long-term path forward," wrote campaign manager Addisu Demissie in the memo to staff ersand supporters. "The next 10 days will determine whether Cory Booker can stay in this race."

The memo added that it is likely that only four candidates presently have enough money to stay in the race for the long haul. These candidates are likely former Vice President Joe Biden, Sens. Elizabeth Warren (D-MA) and Bernie Sanders (I-VT), and South Bend Mayor Pete Buttigieg, who report the largest fundraising hauls.
