Hidden Crater Under Greenland May Explain Sudden Climate Change

Those looking to bolster their argument that not all climate change is manmade may have received an early Christmas gift – researchers have found a massive hidden asteroid impact crate under Greenland whose age coincides with the beginning of a previously unexplained cooling period about 12.000 years ago. Does this change everything?

“The crater is exceptionally well-preserved, and that is surprising, because glacier ice is an incredibly efficient erosive agent that would have quickly removed traces of the impact. But that means the crater must be rather young from a geological perspective.”

In a press release announcing the study “A large impact crater beneath Hiawatha Glacier in northwest Greenland” published in the current edition of Science Advances, co-author Professor Kurt H. Kjær from the Center for GeoGenetics at the Natural History Museum of Denmark describes how researchers first found signs pointing to the existence of the crater under Greenland’s ice sheet in July 2015. It was not far from where a 20-ton iron meteorite had been discovered, but that wasn’t enough to connect the dots.

Is any part of Greenland not covered by glaciers?

A German research plane from the Alfred Wegener Institute flew over the Hiawatha Glacier and, using a new ice radar system, was able to better image the depression and added to the evidence, exciting NASA glaciologist Joseph MacGregor. (Pictures here.)

“A distinctly circular rim, central uplift, disturbed and undisturbed ice layering, and basal debris. It’s all there.”

Surface expeditions in 2016 and 2017 collected samples of sediment washed out from under the depression and found the missing link.

“Some of the quartz sand washed from the crater had planar deformation features indicative of a violent impact, and this is conclusive evidence that the depression beneath the Hiawatha Glacier is a meteorite crater.”

The crater measures more than 31 km (19.25 miles) in diameter, which puts the size of the iron meteorite at 1 km (.6 miles) wide and puts the impact in the top 25 of Earth impact craters, making it a good candidate for causing ecological disasters. Ice layers show it’s at least 12000 years old and rock erosion samples say it’s no more than 3 million years old.

It’s the more recent date that has scientists linking the event to the Younger Dryas period – a sudden unexplained cooling during a time of global warming after the last ice age. Occurring about 12,900 to 11,700 years ago, geological records in the Northern Hemisphere indicate a swift drop in temperatures of 2 to 6 degrees Celsius (3.6 to 10.8 degrees Fahrenheit), increases in glacier ice and cold waters in the Atlantic and general drier conditions. While the cooling was widespread, a few areas, southeastern North America for one, had a slight warming. The Younger Dryas coincided with a number of human cultures shifting from hunting and nomadic life to agriculture and settlements. In North America, the Clovis culture declined and a number of animal species went extinct.

All of these things could certainly have been caused by a meteor impact of catastrophic size. Is that the answer to the cause of the Younger Dryas that scientists have been searching for?

“The next step in the investigation will be to confidently date the impact. This will be a challenge, because it will probably require recovering material that melted during the impact from the bottom of the structure, but this is crucial if we are to understand how the Hiawatha impact affected life on Earth.”

Sounds like Kjær is making his plans for next summer. Pack a parka, professor!

A tourist fell into a fire trap: published a creepy video from California

The video, which was filmed in the Sierra National Forest, located in California, shows how one of the holidaymakers was in the heart of a fire trap.

This vacationer turned out to be just one person out of 207 who were also captured in the fire and were saved in the very last moments. The rescue service came to their aid, which took people to a safe place. 

In the video, which was made by a man on the estate of Jeremy Remington, you can clearly see how cars burn, and the flame is getting closer to tourists and its speed is noticeably increasing.

People were in a real trap. Fire surrounded them on all sides, and the roads that could be driven were destroyed. According to the information provided by the Emergency Situations Department, work to rescue tourists began on Saturday evening and continued until Sunday morning. 

More than 20 people had to be transported to hospitals. Two of the victims were in critical condition and required immediate medical attention. At the same time, two people who were vacationing in the National Forest refused the proposed evacuation.

The scale of the wildfire that started on Friday is not too large. But at the same time, the fire managed to destroy more than 71 square miles of forest. By the middle of Saturday, due to the increase in the rate of spread of fire, a 7 times larger area was destroyed. 

On Sunday morning, it was possible to stop the fire by no more than 5%, so the work continued actively and further.

Great solar minimum and the onset of the Little Ice Age

Niels-Axel Mörner is the former head of the Department of Paleogeophysics and Geodynamics at Stockholm University. He retired in 2005 and has since dedicated his days to refuting the global warming bullshit as well as warning of an impending Great Solar Minimum.

From 1997 to 2003, Moerner led the INTAS project on geomagnetism and climate. The project concluded that in the middle of the 21st century we should return to a new solar minimum with climatic conditions of the Little Ice Age.

In 2015, Moerner’s study “Approaching New Great Solar Minimum and Climatic Conditions of the Little Ice Age” was published. 

The conclusions are that by 2030–2040 the Sun will experience a new large solar minimum. 

During the previous large solar minima – the Sperer Minimum (1440-1460), the Maunder Minimum (1687-1703), and the Dalton Minimum (1809-1821) – climatic conditions worsened and the Little Ice Age began.

During the last three large solar minimums – the Sperer, Maunder and Dalton minimums – the global climate has experienced Little Ice Age conditions. Arctic waters penetrated south as far as Central Portugal and Europe experienced harsh climatic conditions. The ice cover of the Arctic has expanded significantly.

We now have data indicating that by 2030-2040. A New Great Solar Minimum will come, which, by analogy with past minimums, will lead to a significant deterioration of the climate with the expansion of ice in the Arctic and global cooling.

All this excludes the theory of global warming, instead of warming, we will face a new Little Ice Age .

California wildfires create giant “volcanic” clouds

California is now burning like hell and fires are creating huge pyrocumulus clouds as a result of intense heating of the air from the surface. 

The heat from the fires spreads so much that it creates its own pyrocumulus cloud systems, each up to 9 km high. These clouds make fire fighting very difficult. 

The intense heat causes convection, which causes the air mass to rise very high, causing apocalyptic clouds.

Common clouds form when the sun heats up the earth’s surface, causing water to evaporate and rise into the atmosphere, where it cools and condenses into a cloud.

This is a relatively slow process compared to the formation of a pyrocumulus cloud, when the intense heat of a huge forest fire burns moisture from vegetation. Then this moisture accumulates on the smoke particles and quickly condenses, rising up. 

Pyrocumulus clouds are more commonly seen over volcanic eruptions, which produce a lot of steam. If you’ve ever seen an ominous cloud creating dry lightning over a volcano, then this is a pyrocumulus cloud. They are black or dark brown due to volcanic ash, and those from wildfires are usually dark gray due to smoke and ash.

The rate at which pyrocumulus clouds form and change, combined with the heat from the fire, can lead to rapid and severe temperature fluctuations in the atmosphere, causing unpredictable and high winds.

They can exacerbate the intensity of forest fires and cause them to move or otherwise behave in unpredictable ways. And all this can endanger the lives of firefighters and people. 

However, if the fire is large enough, the cloud can continue to grow and turn into a cumulonimbus cloud, which can cause powerful thunderstorm activity, and lightning in turn can trigger another fire.
