NASA expects global cooling with solar minimum, CO2 only tiny part of extremely long cycles, Low sunspot activity, Another “Little Ice Age” coming?

“We see a cooling trend,”  “High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold.”…Martin Mlynczak, NASA’s Langley Research Center.

“Two periods of unusually low sunspot activity are known to have occurred within the Little Ice Age period: the Spörer Minimum (1450–1540) and the Maunder Minimum (1645–1715). Both solar minimums coincided with the coldest years of the Little Ice Age.”…Encyclopedia Britannica

“Amidst Global Warming Hysteria, NASA Expects Global Cooling
Those promoting CO2 as the reason for global warming are hucksters and those taken in by hucksters.

“We see a cooling trend,” said Martin Mlynczak of NASA’s Langley Research Center. “High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold.”

The new data is coming from NASA’s Sounding of the Atmosphere using Broadband Emission Radiometry or SABER instrument, which is onboard the space agency’s Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite. SABER monitors infrared radiation from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a vital role in the energy output of our thermosphere, the very top level of our atmosphere.

“The thermosphere always cools off during Solar Minimum. It’s one of the most important ways the solar cycle affects our planet,” said Mlynczak, who is the associate principal investigator for SABER.

The new NASA findings are in line with studies released by UC-San Diego and Northumbria University in Great Britain last year, both of which predict a Grand Solar Minimum in coming decades due to low sunspot activity. Both studies predicted sun activity similar to the Maunder Minimum of the mid-17th to early 18th centuries, which coincided to a time known as the Little Ice Age, during which temperatures were much lower than those of today.

If all of this seems as if NASA is contradicting itself, you’re right — sort of. After all, NASA also reported last week that Arctic sea ice was at its sixth lowest level since measuring began. Isn’t that a sure sign of global warming?

All any of this “proves” is that we have, at best, a cursory understanding of Earth’s incredibly complex climate system. So when mainstream media and carbon-credit salesman Al Gore breathlessly warn you that we must do something about climate change, it’s all right to step back, take a deep breath, and realize that we don’t have the knowledge, skill or resources to have much effect on the Earth’s climate.

Incredibly Complex Systems

See the problem? Alarmists take one variable, CO2 that is only a tiny part of extremely long cycles and make projections far into to the future based off it.

When I was in grade school, the alarmists were worried about global cooling. Amusingly, I recall discussing in science class the need to put soot on the arctic ice to melt it to stop the advance of glaciers.

​The latest Intergovernmental Panel on Climate Change (IPCC) Report said we have only 12 years left to save the planet. It triggered the usual frantic and ridiculous reactions.

NBC News offered this gem: “A last-ditch global warming fix? A man-made ‘volcanic’ eruption” to cool the planet.” Its article proclaimed, “Scientists and some environmentalists believe nations might have to mimic volcanic gases as a last-ditch effort to protect Earth from extreme warming.”

Geo-engineering: Ignoring the Consequences

Watts Up With That discusses Geo-Engineering: Ignoring the Consequences.

From 1940 to almost 1980, the average global temperature went down. Political concerns and the alleged scientific consensus focused on global cooling. Alarmists said it could be the end of agriculture and civilization. Journalist Lowell Ponte wrote in his 1976 book, The Cooling.

The problem then was – and still is now – that people are educated in the false philosophy of uniformitarianism: the misguided belief that conditions always were and always will be as they are now, and any natural changes will occur over long periods of time.

Consequently, most people did not understand that the cooling was part of the natural cycle of climate variability, or that changes are often huge and sudden. Just 18,000 years ago we were at the peak of an Ice Age. Then, most of the ice melted and sea levels rose 150 meters (490 feet), because it was warmer for almost all of the last 10,000 years than it is today.

During the cooling “danger,” geo-engineering proposals included:

* building a dam across the Bering Straits to block cold Arctic water, to warm the North Pacific and the middle latitudes of the Northern Hemisphere;

* dumping black soot on the Arctic ice cap to promote melting;

* adding carbon dioxide (CO2) to the atmosphere to raise global temperatures.

Taking carbon dioxide out of the atmosphere,” as advocated by the IPCC in its October 8 news conference, is also foolish. Historic records show that, at about 410 parts per million (ppm), the level of CO2 supposedly in the atmosphere now, we are near the lowest in the last 280 million years. As plants evolved over that time, the average level was 1200 ppm. That is why commercial greenhouses boost CO2 to that level to increase plant growth and yields by a factor of four.

The IPCC has been wrong in every prediction it’s made since 1990. It would be a grave error to use its latest forecasts as the excuse to engage in geo-engineering experiments with the only planet we have.
