Blockade Australia shut down Sydney with climate change protests. Now they’re fighting arrests in court

In a white-walled room inside a community center in Sydney’s inner west, about 20 people are sitting in a circle.

One of them, a young man in a beanie, starts reading from a pamphlet:

“Corporate and institutional power is driving the climate crisis and blocking climate action.”

He’s a member of Blockade Australia, the protest group which shut down parts of Sydney in late June.

Today — June 26 — is the day before that happened.

“The very system we’re in is one of domination, so to resist that we have to be able to organize in a different way — organizing non-hierarchically and co-existing non-hierarchically.”

Sitting on a floor of rough gray carpet tiles, the small audience is nodding in agreement as the young man in a beanie continues.

“Blockade Australia is a coordinated response that aims to develop a culture of effective resistance through strategic direct action.”

All Blacks v Springboks: Duane Vermeulen back as South Africa change five for second All Blacks test

Duane Vermeulen is back at No. 8 for his first test this year as South Africa made five changes to its starting lineup today for its second Rugby Championship game against New Zealand.

Two of those changes were forced, with Jaden Hendrikse at scrumhalf in place of Faf de Klerk, who was ruled out with concussion. Jesse Kriel is called in on the right wing to replace Kurt-Lee Arendse, who was sent off and also sustained a concussion in the Springboks’ 26-10 win over the All Blacks in Mbombela on Sunday.

Arendse was suspended for four weeks for the dangerous midair tackle on Beauden Barrett that led to his red card and his injury.

South Africa coach Jacques Nienaber also made two tactical switches in the front row for the game at Ellis Park in Johannesburg on Saturday by bringing in Ox Nché for Trevor Nyakane at loosehead prop and restoring Bongi Mbonambi as starting hooker in place of Malcolm Marx. Tighthead prop Frans Malherbe is set for his 50th test.

Herschel Jantjies was called up to the reserves as scrumhalf cover and Jasper Wiese dropped to the bench to make way for the return of the 36-year-old Vermeulen, who has recently undergone knee surgery.

“Duane has a massive presence on the field and there is no bigger game for him to make his comeback from injury than facing the All Blacks,” said Nienaber.

The Springboks are seeking back-to-back wins over the All Blacks for the first time since 2009 and another defeat for New Zealand is expected to see coach Ian Foster lose his job. The All Blacks have lost five of their last six tests to slip to an all-time low of No. 5 on the world rankings.

Foster is expected to name his team for Ellis Park on Thursday and has injury doubts over Beauden Barrett at flyhalf and his brother Jordie at fullback.

New Study Offers a Surprising Timeline For Earth’s Sixth Mass Extinction

A climate scientist at Tohoku University in Japan has run the numbers and does not think today’s mass extinction event will equal that of the previous five. At least not for many more centuries to come.

On more than one occasion over the past 540 million years, Earth has lost most of its species in a relatively short geologic time span.

These are known as mass extinction events, and they often follow closely on the heels of climate change, whether it be from extreme warming or extreme cooling, triggered by asteroids or volcanic activity.

When Kunio Kaiho tried to quantify the stability of Earth’s average surface temperature and the planet’s biodiversity, he found a largely linear effect. The greater the temperature change, the greater the extent of extinction.

For global cooling events, the greatest mass extinctions occurred when temperatures fell by about 7°C. But for global warming events, Kaiho found the greatest mass extinctions occurred at roughly 9°C warming.

That’s much higher than previous estimates, which suggest a temperature of 5.2°C would result in a major marine mass extinction, on par with the previous ‘big five’.

To put that in perspective, by the end of the century, modern global warming is on track to increase surface temperatures by as much as 4.4°C.

“The 9°C global warming will not appear in the Anthropocene at least till 2500 under the worst scenario,” Kaiho predicts.

Kaiho is not denying that many extinctions on land and in the sea are already occurring because of climate change; he just does not expect the same proportion of losses as before.

Still, it’s not just the degree of climate change that puts species at risk. The speed at which it occurs is vitally important.

The largest mass extinction event on Earth killed off 95 percent of known species at the time and occurred over 60,000 years about 250 million years ago. But today’s warming is occurring on a much shorter timescale thanks to human emissions of fossil fuels.

Perhaps more species will die off in Earth’s sixth extinction event not because the magnitude of warming is so great, but because the changes happened so quickly that many species could not adapt.

“Prediction of the future anthropogenic extinction magnitude using only surface temperature is difficult because the causes of the anthropogenic extinction differ from causes of mass extinctions in geological time,” Kaihu admits.

Whichever way scientists slice up the data, it’s clear that many species are doomed unless we can halt climate change.

The exact percentage of losses and the timing of those losses remains up for debate.

The study was published in biogeosciences.
