Chilling Secrets: Rocks Beneath Antarctic Ice Sheet Reveal Surprising Past
Scitech Daily ^ | June 1, 2023 | British Antarctic Survey

Posted on 06/03/2023 8:51:57 AM PDT by SunkenCiv

The study used rock samples to show that ice near Thwaites Glacier was at least 35 meters thinner in the last 5000 years and took a minimum of 3000 years to reach its current size... The team discovered that the rocks they collected were not always covered by ice. Their measurements showed that, during the past 5000 years, ice near Thwaites Glacier was at least 35 meters thinner than it is now. Furthermore, their models demonstrated that its growth since then – making the ice sheet the size it is today – took at least 3000 years. This discovery reveals that ice sheet retreat in the Thwaites Glacier region can be reversed. The challenge for scientists now is to understand the conditions required to make that possible.

we need some greenhouse gases - it’s been 12,000 years since the last Ice Age and we’d like to keep it that way

The earths plates are always on a slow move every landscape changes over the years some deserts were tropical.

In 2000 million years California will be near Alaska thank God.

Roman times were warmer, so was the time around 1000 AD when the vikings had vineyards on Newfoundland.

They always forget the sun.
Our star warms all 9 of the planets yet to the “scientists’ they leave out the power the sun has over everything here on earth.

” Furthermore, their models demonstrated that its growth since then – making the ice sheet the size it is today – took at least 3000 years.”

“Models” are not reality and are only as good as the garbage input into them. That means the output is garbage equal to the input garbage. The data is all assumptions impossible to measure accurately because there was no one there measuring directly. It’s all based on some proxy data they ASSUME might be associated with what they want it to be useful to build a model.

While this model does blow the globull warmist panickers out of the solid water, it is just so much nose picking and belly button lint examining as their own model building.

Using the logic of the authors (global warming causes glaciers to melt), then the earth was warmer 5000 years ago than it is now. Isn’t it odd that the word ‘warmer’ isn’t even mentioned in the article?

This is great news! The earth was warmer then, and mankind survived!

Glaciers grow when more snow falls than melts.

Either heavier snowfalls or colder temperatures will do the job.

It requires only heavier snowfalls as the colder temperature is always there… colder temperatures in the more souther points of the northern hemisphere is also required to extend the range of ice.

But ask yourselves, how does the precipitation in the form of snow and ice, sleet, hail, GET into the atmosphere in larger amounts in the first place to create heavier snow and ice falls? The answer is greater heat in the tropics to evaporate water from the oceans to put that water vapor into the upper stratosphere where it migrates both north and south to convert to heavier ice crystals and precipitates and falls.

In other words, increases in greenhouse gases are MORE likely to cause a new ice age than melt the ice caps.

Silly Climate Change denier, use something more obvious as a cause than denying the truth handed down by Saint Al Gore. It’s obvious to any right thinking person that this anomaly that Space Aliens were mining ice from this area for their Marstinis after using up all the ice on Mars. This was of course before they all got arrested for DUIs in the UFOs… SHEESH! Be Logical will ya!

This simple, but logical and scientific explanation, covers the thinner ice completely without having to change all the settled science and having to send back all those lovely and very lucrative climate change grants.

“The challenge for scientists now is to understand the conditions required to make that possible”The absence of advanced human civilization burning fossile fuels and feeding off of farting cows.

Go back to insects ruling the natural world and the glaciers will take care of themselves.

Other items found under miles of ice:

Areas that are now Chicago, New York, most of Canada were under miles of ice. The cold and ice will return, and all we can do is adapt.

Decades ago, Antarctic ice cores showed that CO2 rose thousands of years after the climate warmed, meaning that the CO2 resulted from it, rather than the other way around — probably due to increased biological activity.

The search for Earth’s hidden mountains
https://www.bbc.com/future/article/20230605-the-hidden-mountains-lurking-deep-within-our-planet

Zaria Gorvett
5th June 2023
The deep Earth contains vast mountain ranges with peaks up to four times the height of Everest. But no one knows why.

“One idea is that the mountains are parts of the lower mantle that have been superheated due to their proximity with Earth’s incandescent core. While the mantle can reach 3,700C (6,692F), this is relatively mild – the core can achieve atom-bending highs of 5,500C (9,932F) – not far off the temperature at the surface of the Sun. The hottest parts of the core-mantle boundary, it is suggested, may become partially molten – and this is what geologists see as ULVZs.

“Alternatively, the deep-Earth mountains could be made from a subtly different material to the surrounding mantle. Incredibly, it’s thought that they could be the remains of ancient oceanic crust which disappeared into its depths, eventually sinking down over hundreds of millions of years to settle just above the core.

“In the past, geologists have looked to a second puzzle for clues. The deep-Earth mountains tend to be found near other mystery structures: enormous blobs, or large low-shear velocity provinces (LLSVPs). There are just two: an amorphous lump called “Tuzo” beneath Africa, and another known as “Jason” beneath the Pacific. They are thought to be truly primeval, possibly billions of years old. Again, no one knows what they are, or how they got there. But their close proximity to the mountains has led to the belief that they’re somehow linked.”
