Climate Tipping Point Discovered

“Scientists say” all warming over the past 120 years was caused by CO2 emissions from humans and volcanoes.

This corresponds with the sudden and rapid increase in temperatures in 1880, after a millenium of steady cooling.

This tells us that the climate tipping point is 280 PPM CO2, and that the only way stop the world from burning up is to go back to a preindustrial lifestyle, and to put a plug in the volcanoes.

It is quite likely that the excessive use of rickshaws in 1880 caused the climate to heat up and warm out of control.

We have to get atmospheric CO2 back down to 279 PPM, to keep the world from burning up. And we need President Elizabeth Warren to communicate to the volcanoes that they must stop their evil activities.

St Greta To Skip School Altogether Next Year

Climate activist Greta Thunberg will skip school for a whole year starting this summer.

The 16-year-old Swede plans to concentrate on her fight against climate change after finishing her ninth grade, German press agency dpa has learned. In September, she intends to attend the United Nations Climate Change Summit in New York, and in December, she will attend the UN Climate Change Conference in Santiago de Chile.

She is not worried about her academic career, Thunberg said. She’ll just go to high school one year later. Normally, young Swedes move to a secondary school in August. Compulsory schooling is only required in the first nine years. Thunberg is considered the initiator of the “Fridays for Future” movement.

Since Thunberg does not fly as a principle of for climate protection reasons, her family is considering alternatives for getting overseas. The is therefore to cross the Atlantic by ship.

The Swedish newspaper “Dagens Nyheter” was the first to report about Thunberg’s plans. It quoted the activist as saying that it was very hard for her making the decision to skip school, but it was clear that something had to happen right now in the fight against climate change . “By 2020, if we want to have any chance of staying below 1.5 or 2 degrees of warming, we’ll have to turn the emission curve steeply down.”

Sun’s Mysterious 11-Year Cycle Appears to Be Driven by Alignment of The Planets

New study corroborates the influence of planetary tidal forces on solar activity

Every 11 years, the Sun cycles through from riotous flare and sunspot activity to a quieter period, before ramping up again. It’s almost as regular as clockwork, and for years astronomers have been wondering what causes it. Now, they’ve proposed a new solution.

Even though the Solar System’s planets are much smaller than the Sun, the gravity of some of them is able to influence our star’s magnetic field. This, the researchers assert, is what controls the solar cycle.

Venus, Earth, and Jupiter assert a small gravitational tug on the Sun as they orbit it. The result is comparable to the way the Moon’s gravity influences Earth’s tides, producing a regularly timed ebb and flow.

The team has traced back 1,000 years of solar cycles, between the years 1000 and 2009 CE, comparing that data against the movements of the planets in that time. They found an impressively strong link between the two.

“There is an astonishingly high level of concordance: what we see is complete parallelism with the planets over the course of 90 cycles,” said physicist Frank Stefani of the Helmholtz-Zentrum Dresden-Rossendorf in Germany.

“Everything points to a clocked process.”

What the team found is that the tidal forces are strongest when Earth, Venus, and Jupiter align, and that this alignment occurs every 11.07 years – falling at the same time as the solar minimum.

The effect is a weak one, unable to affect the Sun’s interior. This, potentially, could be why no one has previously connected the dots between the solar cycle and the periodicity of the planetary alignment.

But the team has found that despite being weak, the tidal forces can still affect the Sun’s magnetic field; in particular, they can influence oscillations in something called the Tayler instability. Such instabilities appear in toroidal (or doughnut-shaped) magnetic fields, where pressure is applied perpendicular to the field’s direction.

This causes the field to become compressed, like a spinal column, creating instabilities a bit like slipped discs. These ‘slipped discs’ in the magnetic field are the Tayler instabilities, and they create perturbations in the solar flux and magnetic field.

Even a small amount of energy – such as, say, from a tidal event – can reverse the oscillations of these perturbations. And if those tidal events were occurring, for example, every 11 years or so, they could trigger a cyclic reversal in the polarity of the magnetic field, resulting in regular fluctuations in activity that corresponds to the cycle.

“When we discovered the current-driven Tayler instability undergoing helicity oscillations in our computer simulations,” Stefani said, “I asked myself: What would happen if the plasma was impacted on by a small, tidal-like perturbation?

“The result was phenomenal. The oscillation was really excited and became synchronised with the timing of the external perturbation.”

Defeated Climate Campaigners Lick Their Lost Election Wounds

Did environmental groups fail to read public sentiment? And did they, in fact, help Australia’s Coalition Govt to victory?

Like many Australians, green groups were surprised by the federal election result.

The Climate Council, Greenpeace, the Australian Conservation Foundation and the Wilderness Society all invested significant resources in the weeks leading up to the May 18 poll.

Underlying much of their campaigning was the belief that the majority of voters wanted stronger climate action.

But the results did not seem to bear that out.

Did environmental groups fail to read public sentiment? And did they, in fact, help the Coalition to victory?

‘Lecturing people in the community’

Former Greens leader Bob Brown led the now-infamous Stop Adani Convoy from Hobart, through Melbourne and Sydney, right into Central Queensland.

It was the epitome of what some describe as trying to “drive change from out of town”.

One of Australia’s leading social researchers, Rebecca Huntley, said the Stop Adani Convoy strategy was bound to fail.

“People from outside the area coming in — that just pisses people off,” said Dr Huntley, who heads up Vox Populi Research.

Paul Williams is a senior lecturer in politics at Griffith University in Queensland and is one of the country’s foremost experts on elections in that state.

He said the Stop Adani Convoy probably cost Labor at least “tens of thousands of votes” in Queensland, if not “hundreds of thousands”.

“That doesn’t mean the Queenslanders are in love with Adani — they’re not,” said Dr Williams.

“Adani became totemic — it was a totem for development and for blue-collar job creation.”

Here’s what we know — and still don’t know — about Adani’s Carmichael coal mine project in central Queensland.

The chief of Farmers for Climate Action grew up farming in Western Australia and now spends her time campaigning and organising all around the country, including in rural Queensland.

But she agreed the convoy was counterproductive.

“I think the polls would reflect how successful that strategy was,” she said. “It’s very hard to drive change from out of town.”

Many in the Coalition have also credited the Stop Adani Convoy for helping them win seats in Queensland.

Dr Brown remained confident the strategy was the right one.

Ms Morgan-Schmidt said the strength of any social movement “comes from within and from being part of that community”.

“We need to really talk and connect with people where they are,” she said.

Kelly O’Shanassy, chief of the Australian Conservation Foundation, agreed one lesson from the election was that environmental groups needed to do more local organising.

“I think that change — when you’re talking about change in a specific community — needs to be done within that community,” said Ms O’Shanassy.

The Climate Council’s Amanda McKenzie said the Stop Adani Convoy was a mistake, and her movement needed to convince people that their community could benefit from the change they were calling for.

“We are advocating for substantive changes across the economy in all sectors. So you need to do a lot of work in bringing people along,” she said.

Green movement criticising Labor policy

Throughout the campaign, Labor walked an uncomfortable line on Adani. It tried not to openly support its proposed coal mine but also insisted it would not stand in its way.

But on many other issues, the environmental movement did not entirely embrace Labor’s plans either.

Less than two weeks from polling day, Labor announced a radical plan to establish a new Environmental Protection Authority and rewrite federal environment laws.
