If Australians Want Reliable & Affordable Electricity: It’s Coal-Fired Power or Nothing

The debate surrounding Australia’s energy crisis is occupied by two camps: deluded zealots and pragmatic realists. STT sits with the latter: we couldn’t care less whether electricity was generated using doggie doo, provided it’s available and affordable, to all-comers. Australia, as the world’s third largest exporter of uranium, ought to be throwing its money and … Continue reading "If Australians Want Reliable & Affordable Electricity: It’s Coal-Fired Power or Nothing"

The coldest place on Earth is nearing the ultimate limits of our planet

Antarctica

A spot of light reading during the current UK heatwave…how does minus 98 degrees Celsius at Earth’s surface sound? This study of Antarctic data finds that ‘the air needs to be extremely dry to get temperatures this far below zero. Any water vapour in the air tends to heat it up, albeit slightly.’

So cold it would be painful to breathe says ScienceAlert.

Just how cold can it get on Earth? Colder than we thought, apparently. A new study of satellite data reports that valleys in Antarctica’s ice sheets can reach close to minus 100 degrees Celsius (or minus 148 degrees Fahrenheit).

Very chilly then, and significantly below the previous record of minus 93 degrees Celsius (minus 135 degrees Fahrenheit) observed in the same area.

Scientists reached the new figure by looking again at remote satellite readings of temperatures on the East Antarctic Plateau, which covers the South Pole, and recalibrating these readings with updated data taken from weather stations on the ground.

The new low point is officially minus 98 degrees Celsius (minus 144 degrees Fahrenheit), a temperature that “appears to be about as low as it is possible to reach” according to the international team of researchers who worked on the new study.

“I’ve never been in conditions that cold, and I hope I never am,” one of the team, Ted Scambos from the University of Colorado-Boulder, told Doyle Rice at USA Today.

“I am told that every breath is painful, and you have to be extremely careful not to freeze part of your throat or lungs when inhaling.”

Such freezing temperatures occur in tiny pockets on the ice, the satellite readings show, up to 3 metres (or 9.8 feet) deep.

Note that this isn’t the same as the lowest temperature ever recorded using instruments at ground level. That honour goes to researchers at Russia’s Vostok Station, also on the East Antarctic Plateau, who gauged the temperature as minus 89 degrees Celsius (minus 128 degrees Fahrenheit) in July 1983.

These new temperatures are readings taken remotely from satellites in space, and scientists like to keep the two separate – here we’re talking about specifically the temperature of Earth’s surface, not the air just above ground, as a weather station would log.

Protesters Aren’t Stopping US Pipeline Network Growth

“With the exception of the New England region, pipeline opponents have failed to halt the growth of US pipeline systems. Oil and gas pipeline networks continue to expand with improving safety, while delivering increasing amounts of petroleum, petroleum products, and natural gas to US residents and businesses.”

Opposition to oil and gas pipelines produces sensational headlines. Protests of the Keystone XL, Dakota Access, and numerous smaller projects are well-covered by the media, creating the impression of an industry halted by public outcry. But the US pipeline network is steadily expanding and safety is improving.

Construction efforts for oil and gas pipelines have long faced opposition from local residents who don’t want a pipeline near their community. But over the last decade, opposition expanded from local to national, involving protesters concerned with supposed impact on the climate and the global environment. Pipelines are no longer opposed for only NIMBY (Not in My Backyard) reasons, but increasingly for NOPE (Not on Planet Earth) reasons.

Keystone XL pipeline opposition is a well-known example. The Keystone XL was originally proposed in 2008 to carry petroleum from the Canadian oil sands, Montana, and North Dakota to US Gulf Coast refineries. Environmental groups, citizens, and politicians attacked the project, warning that the pipeline would harm water supplies and increase global warming.

Global warming environmental activist Bill McKibben was arrested in front of the White House in a Keystone XL protest. Senator Barbara Boxer warned that the pipeline would cause cancer in more Americans.

In November 2015, President Obama rejected the project, stating, “America is now a global leader when it comes to taking serious action to fight climate change. And frankly, approving this project would have undercut that global leadership.” In January 2017, President Trump reversed the Obama rejection and signed a memorandum to advance the Keystone XL, which should begin construction later this year.

The Dakota Access Pipeline, a project to carry crude oil from North Dakota to southern Illinois, was announced in June 2014. The pipeline was opposed by Native Americans and other local groups, but also by national and international groups including Amazon Watch, Black Lives Matter, and Greenpeace. St. Louis, Minneapolis, and 17 other cities passed ordinances opposing the pipeline. Celebrity Leonardo di Caprio, Senator Bernie Sanders, and even United Nations officials called for a halt to the pipeline.

In the spring and summer of 2016, a camp of over 3,000 protesters developed in the path of pipeline construction in Cannon Ball, North Dakota, and received international media coverage. But between September 2016 and January 2017, the camp was cleared by police with about 200 protesters arrested. The pipeline began operation in May 2017 and now transports over 500,000 barrels of oil per day.

With rising protests backed by sympathetic media coverage, one might conclude that the US pipeline network is in decline, but this is not the case. Pipeline networks are expanding and increasingly used to safely transport oil, oil products, natural gas, and volatile liquids such as ethane, butane, and propane.

Driven by increased oil production from the fracking revolution, US crude oil pipeline mileage increased from 49,000 in 2004 to over 75,000 in 2016, according to the Pipeline and Hazardous Materials Safety Administration (PHMSA). But many locations need still more pipeline capacity. Petroleum output is rising so fast in America’s largest oil field, the Permian Basin shale field in West Texas, that pipelines can’t handle it all.

The pipeline network for distributing natural gas to homes and businesses is also growing steadily. Data from the PHMSA shows that gas distribution main and service pipeline mileage grew 80 percent from 1984 to 2016. Gas pipeline mileage continues to steadily expand, despite “electrification” efforts aimed at reducing the use of natural gas and propane in California and New York.

Pipelines are the safest method to transport crude oil, oil products, and natural gas. A 2012 study by the Manhattan Institute used PHMSA data to show that hazardous material incidents for pipeline transportation of oil and gas were roughly one-twentieth of the incidents for rail transportation and hundreds of times less frequent than incidents for truck transportation per billion ton miles.

PHMSA data also shows that the number of serious incidents and fatalities experienced by US pipelines is down roughly 50 percent since 2000, despite the expansion of oil and gas pipeline networks. US residents have about double the chance of dying from a lightning strike than a pipeline accident.

New England is the only region where opposition has prevented most pipeline construction during recent years. Earlier this month, New York Governor Mario Cuomo rejected the proposed Constitution Pipeline, which planned to bring fracked gas from Pennsylvania to the New England pipeline network.

In February, when supplies of gas were tight, Massachusetts imported liquefied natural gas from Russia, needed to heat homes and generate electricity. Massachusetts Attorney General Laura Healey admitted that she would rather import gas from Russia than build a new gas pipeline to her state. Meanwhile, New England residents pay the highest electricity costs in the continental United States, and these prices are rising.

With the exception of the New England region, pipeline opponents have failed to halt the growth of US pipeline systems. Oil and gas pipeline networks continue to expand with improving safety, while delivering increasing amounts of petroleum, petroleum products, and natural gas to US residents and businesses.

PEOPLE WANT CHEAPER HEATING ABOVE CUTTING CO2 EMISSIONS

This article looks at government "virtue signalling" at great cost to people’s energy bills. People are much more interested in keeping costs down than in some theoretical idea of keeping the planet from a little warming in the coming centuries long after their lives are over.
