British scientist calls for ‘major nuclear program’ to head off climate change

Published

on

A leading British academic has called for accelerated research into futuristic geo-engineering and a worldwide nuclear power station “binge” to avoid runaway global warming.

Peter Wadhams, professor of ocean physics at Cambridge University, said both potential solutions had inherent dangers but were now vital as time was running out.

“It is very, very depressing that politicians and the public are attuned to the threat of climate change even less than they were 20 years ago when Margaret Thatcher sounded the alarm. Co2 levels are rising at a faster than exponential rate, and yet politicians only want to take utterly trivial steps such as banning plastic bags and building a few windfarms,” he said.

“I am very suspicious of using technology to solve problems created by technology, given that we have messed up so much in the past but having done almost nothing for two decades we need to adopt more desperate measures such as considering geo-engineering techniques as well as conducting a major nuclear programme.”

Geo-engineering techniques such as whitening clouds by adding fine sprays of water vapour, or adding aerosols to the upper atmosphere have been ridiculed in some quarters but welcomed elsewhere. Wadhams proposes the use of thorium-fuelled reactors, being tested in India, which are said to be safer because they do not result in a proliferation of weapons-grade plutonium, experts say. Also, under certain circumstances, the waste from thorium reactors is less dangerous and remains radioactive for hundreds rather than thousands of years.

Wadhams, who is also head of the polar ocean physics group at Cambridge and has just returned from a field trip to Greenland, was reacting to evidence that Arctic sea ice cover had reached a record low this summer.

This latest rate of loss is 50% higher than most scenarios outlined by other polar scientists and coincide with alarming new reports about a “vast reservoir” of the potent greenhouse gas, methane, that could be released in Antarctica if the ice melts equally quickly there. Greenpeace said last night that it agreed with the academic’s concerns but not with his solutions.

“Professor Wadhams is right that we’re in a big hole and the recent record sea ice low in the Arctic is a clear warning that we need to act. But it would be cheaper, safer and easier to stop digging and drilling for more fossil fuels,” said Ben Ayliffe, the group’s senior polar campaigner.

“We already have the technologies, from ultra-efficient vehicles to state-of-the-art clean energy generation, to make the deep cuts in greenhouse gases that are needed to stave off the worst effects of climate change. Unfortunately, we’re still lacking the political and business will to implement them,” he added.

Wadhams, who has done pioneering work on polar ice thinning using British naval submarines from 1976 onwards, said these latest satellite findings confirmed his own dire predictions.

And they feed into the alarming scenarios that the Arctic Methane Emergency Group have been warning about.

“What we are now seeing is a fast collapse of the sea ice that means we could see a complete loss during the summer by 2015 – rather than the 20 to 30 years talked about by the UK Meteorological Office. This would speed up ocean warming and Greenland ice cap melt and increase global ocean levels considerably as well as warming the seabed and releasing more methane.”

Asked whether the latest evidence made a ban on drilling for carbon-releasing oil and gas necessary as Greenpeace has contended, Wadhams said “philosophically” such exploration made little sense. “We have been conducting a global experiment with the burning of fossil fuels and the results are already disastrous and this would accelerate them,” he argued saying that there were also practical worries because of the enormous difficulty of dealing with any spillage or a blowout under moving ice where oil would get trapped inside the ice in a kind of inaccessible “oil sandwich’.

But he said at least that companies such as Shell had shown some responsibility by carefully planning its expected exploration in the Chukotka Sea off Alaska and had shown a willingness to use ready-made containment domes that could cap off a well if anything went wrong. He was more fearful about drilling methods in the Russian Arctic where environmental concerns were lower down the agenda.

Hope Hicks denied under oath knowing about Trump’s hush-money payments to Stormy Daniels

Published

Former White House communications director Hope Hicks on Wednesday denied under oath knowing anything about the hush-money scheme set up by former Trump "fixer" Michael Cohen to pay off President Donald Trump's former mistresses.

"Hicks told lawmakers today that she did not have knowledge during 2016 campaign of hush-money payments made in run-up to election," reports CNN's Manu Raju. "Also she wouldn’t discuss what she learned about those payments during her time at White House because of immunity claims."

Trump’s 2020 campaign strategy is familiar: Troll the libs!

Published

on

Late on Tuesday, I got an email from an unusual source. A reporter for the conservative publication the Washington Examiner asked if I'd be interested in sharing thoughts on Joe Biden's history of joking "about 'locking up your daughters'" and on "Biden's view of women and gender relations." This was in light of my previous criticisms of Biden's apparent condescension towards girls and women, and his pockmarked history on gender relations in general.

Cory Booker rips Biden for praising racist senators: ‘You don’t joke about calling black men boys’

Published

Sen. Cory Booker (D-NJ) blasted Joe Biden for praising two segregationist senators he'd served with as a lawmaker.

The former vice president and current Democratic presidential frontrunner reminisced about his relationship with Mississippi Democrat James Eastland and Georgia Democrat Herman Talmadge, two notoriously racist senators during the Civil Rights era, reported The Hill.

“At least there was some civility, we got things done," Biden said, recalling that Eastland had never called him "boy." "We didn't agree on much of anything. We got things done, we got it finished."
