Gas is not a transition fuel to a safe climate. That ship has sailed

Gas is not a transition fuel to a safe climate. That ship has sailed, https://www.theage.com.au/environment/climate-change/gas-is-not-a-transition-fuel-to-a-safe-climate-that-ship-has-sailed-20200826-p55pec.html, Penny Sackett, 27 Aug 20

Australia’s chief scientist from 2008 to 2011   If gas-fired electricity emissions can be lower than that from coal-fired plants, should Australia expand its fossil gas industry as a means of combating climate change? The answer is a clear no if we want to avoid the worst climate change outcomes.

Science has repeatedly demonstrated that the most important action to limit global warming to well below 2 degrees is to begin to reduce all fossil fuel consumption – coal, yes, but oil and gas too – in this decade.

The primary difficulty is the large mismatch between what is required to meet that stated climate goal of the Paris Agreement and what nations have actually pledged to do. Worse still, the current policies of many countries, Australia included, would increase their national production of fossil fuels, increasing emissions above their own weak pledges.

This so-called “production gap” is the subject of a recent multi-institutional, multi-national report led by the Swedish Environment Institute. Its analysis shows that governments are planning to produce about 50 per cent more fossil fuels by 2030 than would be consistent with a 2-degree pathway and 120 per cent more than would be consistent with a 1.5-degree pathway. This means that plans for fossil fuel development or extension that are already on the table must be shelved to hold warming to the Paris target range.

Consistent with other research, the report demonstrates that to have a 66 per cent chance of holding warming to well below 2 degrees, coal, oil and gas production must all decline significantly in the next decade. That is why increasing gas development to displace coal is no longer a viable approach to maintaining a reasonably safe climate.

Over the past 30 years, coal-to-gas “fuel-switching” has played a role in reducing emissions in the United States and Britain. However, the latest information from the US Energy Information Administration shows that the US energy grid has decreased its emissions from a shift to non-fossil fuel sources by almost as much as a shift to gas. Despite the shale boom, non-carbon energy sources have now overtaken any other single source of fossil fuel in supplying energy to the US grid.

In Britain, renewables played a large role in reducing emissions in the electricity grid. Between 2006 and 2016, the renewables share of electricity production rose from 2 per cent to 25 per cent, even excluding large hydro. While the 1990’s “dash for gas” was responsible for the largest cumulative amount of avoided greenhouse emissions in Britain since 1990, the situation is different now. In 2017, the transition to renewable energy was the largest driver in its electricity sector’s emission reductions. In second place was lower electricity demand (think what we could do with energy efficiency in Australia), while coal-to-gas switching came in third.

The world we live in has already changed dramatically with global average temperatures now 1.1 degrees above pre-industrial levels. Cyclones and storm surges are more intense. Droughts are more damaging. Fire seasons are longer and bushfires more fierce. Billions of animals died in last year’s Australian bushfires alone. Entire species are becoming extinct at rates far above normal. The point of no return may have already passed for Arctic sea ice – in 15 years, globes in schoolrooms may show white ice at only one pole.

At 2 degrees of warming, heatwaves would be even more severe and more deadly to humans, animals and agriculture. Sydney and Melbourne would need to brace for 50-degree days. The fire weather that produced Australia’s Black Summer would become at least four times more likely, the amount of water available to feed dams and rivers in NSW would be reduced by 30 per cent from what was typical mid last century, and coral reefs around the world would almost certainly be eliminated.

We have all the tools to avoid that future of 2 degrees of warming. What has been lacking is coherent, science-based action that does not add yet more fuel to the climate fire. Today, when the enormous human, economic and ecological costs of even 1.1 degrees of warming are so clear, when prices of renewable energy have plummeted, and several non-fossil energy storage options are available, gas is not a transition fuel to a safe climate. That ship has sailed.

Planned and rapid coal-to-renewables switching is now the responsible path. Gas will have a role in the near term, certainly, but the science is clear. The role of gas needs to be a significantly declining one, not a growing one, if we are to avoid the worst of climate change so that Australia’s future is safe, sustainable and competitively modern.

Disarray in New South Wales Right-wing parties, over One Nation’s Bill to overturn ban on uranium mining

Environmental groups have been critical of the government’s consideration of Mr Latham’s bill, with the Nature Conservation Council warning uranium mining would threaten water supply.

Berejiklian government to pursue its own uranium push, By Alexandra Smith, August 24, 2020

https://www.smh.com.au/politics/nsw/berejiklian-government-to-pursue-its-own-uranium-push-20200824-p55ova.html

The Berejiklian government will pursue its own push to allow uranium mining in NSW, after cabinet ministers backed away from supporting One Nation’s nuclear power bill in the upper house.

The bill, introduced by Mark Latham, would lift the 33-year ban on uranium mining and nuclear power, but on Monday night cabinet agreed that it would consider its own bill.

In March, Deputy Premier John Barilaro stunned colleagues when he said his party would support Mr Latham’s bill, despite not taking the issue to the Nationals’ party room.

Mr Barilaro, a long-time supporter of nuclear power, said the government should “lift the ban on nuclear energy” and confirmed his party would support it.

But the move angered several senior ministers, with one saying: “I did not get into Parliament to support a One Nation bill”, while another said: “Crossbenchers don’t set the government’s agenda”.

A shift in policy around uranium mining in NSW has still not been considered by the Coalition joint party rooms, which will not meet this week because only the upper house is sitting.

Mr Barilaro has now been tasked with commissioning more research around uranium mining and will report back to cabinet before any policy decisions are made.

A senior minister said Transport Minister Andrew Constance told cabinet that he could not support the One Nation bill because it could significantly impact electorates, including Bega.

Another minister told cabinet that there needed to be strategic and economic merit and community consultation around uranium mining.

Asked about the bill before it was presented to cabinet on Monday, NSW Energy Minister Matt Kean said uranium was not a viable resource.

“Right now the uranium price is about $30 per pound, that is well below the price needed to extract this from the ground. I think this is more about headlines than actually going to see anything result from digging it out of the ground,” Mr Kean said.

A senior minister, who spoke on the condition of anonymity because the issue was before cabinet, said “uranium mining will never happen so it’s just about letting Barra [Barilaro] have a win.”

“Sometimes the fights with Barra are just not worth it,” the minister said.

Mr Latham could bring the bill on for a vote this week, after the Legislative Council was recalled for another week of sitting days. The bill has been sitting on the business paper for more than a year.

The upper house is also expected to focus this week on troubled public insurer icare.

Environmental groups have been critical of the government’s consideration of Mr Latham’s bill, with the Nature Conservation Council warning uranium mining would threaten water supply.

The council’s chief executive Chris Gambian said the “sweetheart deal with One Nation yet again places multinationals ahead of the people of regional and rural NSW”.

A parliamentary inquiry report recommended the government support the nuclear power bill.

Ice melting at a surprisingly fast rate underneath Shirase Glacier Tongue in East Antarctica

East Antarctic melting hotspot identified

Summary:
Ice is melting at a surprisingly fast rate underneath Shirase Glacier Tongue in East Antarctica due to the continuing influx of warm seawater into the Lützow-Holm Bay.

Hokkaido University scientists have identified an atypical hotspot of sub-glacier melting in East Antarctica. Their findings, published in the journal Nature Communications, could further understandings and predictions of sea level rise caused by mass loss of ice sheets from the southernmost continent.

The 58th Japanese Antarctic Research Expedition had a very rare opportunity to conduct ship-based observations near the tip of East Antarctic Shirase Glacier when large areas of heavy sea ice broke up, giving them access to the frozen Lützow-Holm Bay into which the glacier protrudes.

“Our data suggests that the ice directly beneath the Shirase Glacier Tongue is melting at a rate of 7-16 meters per year,” says Assistant Professor Daisuke Hirano of Hokkaido University’s Institute of Low Temperature Science. “This is equal to or perhaps even surpasses the melting rate underneath the Totten Ice Shelf, which was thought to be experiencing the highest melting rate in East Antarctica, at a rate of 10-11 meters per year.”

The Antarctic ice sheet, most of which is in East Antarctica, is Earth’s largest freshwater reservoir. If it all melts, it could lead to a 60-meter rise in global sea levels. Current predictions estimate global sea levels will rise one meter by 2100 and more than 15 meters by 2500. Thus, it is very important for scientists to have a clear understanding of how Antarctic continental ice is melting, and to more accurately predict sea level fluctuations.

Most studies of ocean-ice interaction have been conducted on the ice shelves in West Antarctica. Ice shelves in East Antarctica have received much less attention, because it has been thought that the water cavities underneath most of them are cold, protecting them from melting.

During the research expedition, Daisuke Hirano and collaborators collected data on water temperature, salinity and oxygen levels from 31 points in the area between January and February 2017. They combined this information with data on the area’s currents and wind, ice radar measurements, and computer modelling to understand ocean circulation underneath the Shirase Glacier Tongue at the glacier’s inland base.

The scientists’ data suggests the melting is occurring as a result of deep, warm water flowing inwards towards the base of the Shirase Glacier Tongue. The warm water moves along a deep underwater ocean trough and then flows upwards along the tongue’s base, warming and melting the ice. The warm waters carrying the melted ice then flow outwards, mixing with the glacial meltwater.

The team found this melting occurs year-round, but is affected by easterly, alongshore winds that vary seasonally. When the winds diminish in the summer, the influx of the deep warm water increases, speeding up the melting rate.

“We plan to incorporate this and future data into our computer models, which will help us develop more accurate predictions of sea level fluctuations and climate change,” says Daisuke Hirano.

Traditional Owners block road to Adani coal mine in central Queensland

‘We want them out’: Traditional Owners block road to Adani coal mine in central Queensland,  SBS, 24 Aug 20, An Adani spokesperson said construction on the mine was continuing despite the blockade.

Protesters, including Traditional Owners of Wangan and Jagalingou country, have blocked the main road to the controversial Adani Carmichael coal mine in central Queensland.

More than 20 people had established a camp across the road from the site and negotiators from Mackay and the Whitsundays were at the scene, a Queensland Police spokesperson said on Monday afternoon. No arrests had been made.

The blockade follows a decade-long campaign against the construction of the mine, located more than 400 kilometres inland from Mackay, which is set to be one of Australia’s largest coal mines when completed.

Wangan and Jagalingou man Adrian Burragubba said the blockade aimed to re-establish control of the land and force the mining giant to abandon the project.

“We’re taking back control of our land, that’s what we’re doing here. We’re doing it because we’ve been ignored, as the original Wangan and Jagalingou people, we’ve been ignored through this whole process,” he said.

“We demand an end to the destruction of our unceded territory. We demand Adani Australia abandon their Carmichael mine project immediately. We want them out, we want them to pack up and leave our tribal lands.”

Mr Burragubba was bankrupted in 2018 after repeated failed court actions to stop the Galilee Basin project………

Adani downsized the project in 2018 from a 60 million-tonne-a-year mine, costing $16.5 billion, to a 10-to-15 million tonnes a year mine, costing about $2 billion.

Construction of the site commenced in 2019 following final approvals from the federal and state governments. HTTPS://WWW.SBS.COM.AU/NEWS/WE-WANT-THEM-OUT-TRADITIONAL-OWNERS-BLOCK-ROAD-TO-ADANI-COAL-MINE-IN-CENTRAL-QUEENSLAND

Gas is not transition energy we were promised, new research suggests

Gas is not transition energy we were promised, new research suggests, SMH, By Nick O’Malley, August 24, 2020 — The good news about natural gas is that when it is burnt it creates between 40 and 50 per cent less carbon dioxide than coal would to create the same amount of energy.This is why it has been embraced by some climate activists and governments as a useful energy source to replace coal and oil while renewable energy technologies catch up with global energy demand.

But the good news ends there, and there is a lot more to the story.

Before it is burnt natural gas is mostly made up of methane, and methane is estimated to be about 28 times more potent a greenhouse gas than carbon dioxide over a 100-year period.

Over a 20-year period – about the time scientists believe we have to try to prevent the worst impacts of global warming – it is up to 80 times more potent at warming the planet than carbon dioxide.

The United States’ Environmental Protection Agency estimates that for every cubic metre of methane extracted by the US oil and gas industry, 1.4 per cent escapes into the atmosphere as so-called fugitive emissions.

But more recent research suggests this estimate is drastically low, and that, in fact, the industry in the US is leaking 13 million metric tonnes of methane a year, or 2.3 per cent.

It is not yet clear how much fugitive methane is released by the Australian gas industry, but new technologies now allow scientists to accurately measure it and the data is expected to be published in the coming months.

The US Environmental Defence Fund estimated that, in America, if just 3 per cent of methane escapes, gas is no cleaner an energy source than coal……. https://www.smh.com.au/environment/climate-change/gas-is-not-transition-energy-we-were-promised-new-research-suggests-20200824-p55ovg.html

Frank Barnaby, nuclear weapons scientist and global hero

he gave evidence in Japan against the used of mixed uranium and plutonium oxide fuel, known as MOX, in a reactor at Fukushima. “Frank’s testimony was so impressive and read by the governor of the region that it stopped the loading of MOX fuel for more than 10 years,” said Shaun Burnie of Greenpeace International. In 2011, the reactor was overwhelmed by a devastating tsunami, but because of this intervention Japan was spared the release of many hundreds of tons of fission products – “in other words the evacuation of 50 million plus and the end of central Japan as a functioning society.
