End dependence on Chinese mining

BY AARON RINGEL: Import dependence has long posed a strategic vulnerability for the U.S.—particularly when it comes to the “rare earth” metals that make many advanced technologies possible.

The post End dependence on Chinese mining appeared first on CFACT.

Simulations explain Greenland’s slower summer warming, say researchers

‘Temperatures and rates of ice sheet melting both peaked in 2012’ – interesting quote from the report. The researchers assume that natural factors are merely impeding the inevitable warming they expect from carbon dioxide emission increases, but assumptions can be risky.

A puzzling, decade-long slowdown in summer warming across Greenland has been explained by researchers at Hokkaido University in Japan, says Phys.org.

Their observational analysis and computer simulations revealed that changes in sea surface temperature in the tropical Pacific Ocean, thousands of miles to the south, trigger cooler summer temperatures across Greenland.

The results, published in the journal Communications Earth & Environment, will help improve future predictions of Greenland ice sheet and Arctic sea ice melting in coming decades.

“The Greenland ice sheet is melting in the long run due to global warming associated with greenhouse gas emissions, but the pace of that melting has slowed in the last decade,” says Hokkaido University environmental Earth scientist, Shinji Matsumura. “That slowing was a mystery until our research showed it is connected to changes to the El Niño climate pattern in the Pacific.”

El Niño is a natural, cyclic phenomenon that raises the water temperature in the central and east-central equatorial Pacific Ocean.

Scientists know that such large-scale changes alter atmospheric conditions elsewhere due to their association with powerful waves of air pressure called teleconnections.

But climate experts struggled to see how the Pacific El Niño could cool Greenland in the summer, because easterly summer winds in the tropics usually prevent such teleconnections from forming.

In the new study, the team accounted for recent changes in the Pacific El Niño event, which pushed the warmer sea temperatures further north than usual. This took them beyond the influence of the easterly wind and allowed atmospheric teleconnections that stretch up to Greenland to form.

In turn, these teleconnections disrupt the atmospheric conditions and thus the weather around Greenland in the summertime. Specifically, they drive more intense cyclones, which move colder air over the land.

This is enough, the new study shows, to explain the lower-than-expected temperatures and ice melting in the region. Temperatures and rates of ice sheet melting both peaked in 2012.

Dead End Street: There’s No High-Tech Fix For Wind & Solar’s Hopeless Intermittency

Europe’s obsession with intermittent wind and solar has left it exposed to an ambitious Russian who controls the oil and gas on which Europe critically depends.

As Vlad’s Ukrainian adventure bogs down among shattered tanks and morale, his threat to chop oil and gas supplies to Europe increases, revealing just how dependent Europe has become an electricity generated with fossil fuels. The rot had already set in, following Europe’s months long wind drought in the last half of 2021.

The Germans have backflipped on their plans to shutter their coal-fired and nuclear power plants; the French are building 14 new nuclear plants and refurbishing their existing 56 plants; and the Brits are determined to unlock their oil and gas reserves with renewed urgency.

All of which is occurring against the backdrop of what was said to be the “inevitable transition” to an all wind and sun powered future.

In short, the great Green Reset has been exposed as a fraud, and those still peddling it as utterly delusional.

Gregory Wrightstone tackles the subject from an American perspective below.

Green delusion no path to energy independence

When President Biden says that the U.S. will become energy independent by way of programs like the Green New Deal, perhaps the first question to ask is, “Does that make sense?” For any thinking person cognizant of even the basic energy facts, the answer should come back, “No.”

The bulk of U.S. energy consumption in 2020, according to the U.S. Energy Information Administration (EIA), broke down as follows: 79 percent from petroleum, natural gas and coal and nine percent from nuclear-generated electricity. Solar and wind — the darlings of Green New Dealers — provided less than five percent.

So, are so-called green sources going to replace hydrocarbons anytime soon? Common sense suggests not. But if that isn’t good enough, there are plenty of data supporting a negative answer.

One man steeped in facts and figures is Mark Mills of the Manhattan Institute. He puts it this way:

“Scientists have yet to discover, and entrepreneurs have yet to invent, anything as remarkable as hydrocarbons in terms of the combination of low-cost, high-energy density, stability, safety, and portability. In practical terms, this means that spending $1 million on utility-scale wind turbines, or solar panels will each, over 30 years of operation, produce about 50 million kilowatt-hours (kWh)—while an equivalent $1 million spent on a shale rig produces enough natural gas over 30 years to generate over 300 million kWh.”

Mr. Mills says there is a fundamental misunderstanding about technological development that contributes to fanciful notions — like the president’s — that solar, wind and batteries can become dominant sources with a mere declaration from the White House or lobbying Congress.

“This ‘new energy economy’ rests on the belief—a centerpiece of the Green New Deal and other similar proposals both here and in Europe—that the technologies of wind and solar power and battery storage are undergoing the kind of disruption experienced in computing and communications, dramatically lowering costs and increasing efficiency,” he says.

“But this core analogy glosses over profound differences, grounded in physics, between systems that produce energy and those that produce information. In the world of people, cars, planes, and factories, increases in consumption, speed, or carrying capacity cause hardware to expand, not shrink. The energy needed to move a ton of people, heat a ton of steel or silicon, or grow a ton of food is determined by properties of nature whose boundaries are set by laws of gravity, inertia, friction, mass, and thermodynamics—not clever software.”

In other words, there is a major difference between the possibilities for technological progress in the things that use energy — smart phones and computers, for example — and in the ways to make energy.

“(S)ometimes, the old or established technology is the optimal solution and nearly immune to disruption,” says Mr. Mills. “We still use stone, bricks, and concrete, all of which date to antiquity. We do so because they’re optimal, not ‘old.’ So are the wheel, water pipes, electric wires … the list is long. Hydrocarbons are, so far, optimal ways to power most of what society needs and wants.”

This is partly why 70 percent of likely U.S. voters recently told Rasmussen that they favor the government’s encouraging increased oil and gas production to reduce dependence on foreign sources. Most people want reliable, affordable energy, and hydrocarbons give it to them.

In addition to fossil fuels being exceptional sources of energy, some of the alternatives are turning out to be more of a public nuisance than an environmental benefit.

“Of the many whoppers that renewable-energy promoters use while advocating for huge increases in the use of wind and solar, the most absurd claim is that building massive amounts of new renewable energy capacity won’t require very much land,” says Robert Bryce in a Forbes article.

Concerns that include land use, noise and aesthetics have led to more than 300 U.S. wind projects being rejected or restricted since 2015 and 13 large solar projects being turned down in 2021 alone, according to Mr. Bryce’s count.

The backlash, he says, “is raging from the fishing docks in Montauk and Rhode Island, to … Vermont (where, by the way, you can’t build wind turbines), out west to Shasta County and Oahu, as well as in Canada, Germany, France, Australia and other countries around the world.”

In Britain, a political movement against Prime Minister Boris Johnson’s Net Zero policy to “decarbonise” the economy by 2050 is being launched by Nigel Farage, the former Brexit Party leader.

“If we are not careful, the only zero will be the amount in people’s bank accounts as we send our jobs and money overseas,” says Mr. Farage.

So, whether it’s laws of physics or forces of economics and politics, there is plenty to keep the green energy dream just that — a fevered vision of a climate cult.
