Earth can regulate its own temperature over millennia, new study finds Scientists have confirmed that a “stabilizing feedback” on 100,000-year timescales keeps global temperatures in check.

The Earth’s climate has undergone some big changes, from global volcanism to planet-cooling ice ages and dramatic shifts in solar radiation. And yet life, for the last 3.7 billion years, has kept on beating.

Now, a study by MIT researchers in Science Advances confirms that the planet harbors a “stabilizing feedback” mechanism that acts over hundreds of thousands of years to pull the climate back from the brink, keeping global temperatures within a steady, habitable range.

Just how does it accomplish this? A likely mechanism is “silicate weathering” — a geological process by which the slow and steady weathering of silicate rocks involves chemical reactions that ultimately draw carbon dioxide out of the atmosphere and into ocean sediments, trapping the gas in rocks...

“You have a planet whose climate was subjected to so many dramatic external changes. Why did life survive all this time? One argument is that we need some sort of stabilizing mechanism to keep temperatures suitable for life,” Arnscheidt says..

In other words, as the Earth’s temperatures fluctuate over longer stretches, these fluctuations may just happen to be small enough in the geologic sense, to be within a range that a stabilizing feedback, such as silicate weathering, could periodically keep the climate in check, and more to the point, within a habitable zone.

Excerpt. I do not know if their conclusion as to "how" is correct, but I do believe that like as the human body has been over-engineered - by the Omniscient omnipotent Engineer - so has the earth.

We should shudder (and would shiver) at globalist attempts to engineer the climate, and which is loath to report on the benefits of higher temps in relatively recent history, however cooked stats may have been in efforts to promote a crisis to justify the increased acquisition of power by globalists.

But considering the nearly million of tons of bombs dropped in the last century, plus 2,000 nuclear tests (though not all were above ground) then that alone is a test of the earth's resilience, though it takes time to deal with it all.

Meanwhile, God does send judgments, and the world will see what is predicted in the book of Revelation, and the priority for all should be to seek the Lord while He may be found, in repentance and faith in the risen Lord Jesus, who alone can save such, on His expense, by His sinless shed blood. Thanks be to God.

Look up “milankovitch cycles” on the interweb.

Gee, you would almost think there was designer. Who woulda thunk?

My favorite “were all gonna die” story involves The Population Bomb author/scaremonger Paul Ehrlich, and the legendary (at least in my mind) The Bet.

Per Wiki, economist Julian Simon was highly skeptical of Ehrlich’s claims in his book, so proposed a wager, telling Ehrlich to select any raw material he wanted and select "any date more than a year away," and Simon would bet that the commodity's price on that date would be lower than what it was at the time of the wager.

Ehrlich and his colleagues picked five metals that they thought would undergo big price increases: chromium, copper, nickel, tin, and tungsten. Then, on paper, they bought $200 worth of each, for a total bet of $1,000, using the prices on September 29, 1980, as an index. They designated September 29, 1990, 10 years hence, as the payoff date. If the inflation-adjusted prices of the various metals rose in the interim, Simon would pay Ehrlich the combined difference. If the prices fell, Ehrlich et al. would pay Simon.

Between 1980 and 1990, the world's population grew by more than 800 million, the largest increase in one decade in all of history. But by September 1990, the price of each of Ehrlich's selected metals had fallen. Chromium, which had sold for $3.90 a pound in 1980, was down to $3.70 in 1990. Tin, which was $8.72 a pound in 1980, was down to $3.88 a decade later.

As a result, in October 1990, Paul Ehrlich mailed Julian Simon a check for $576.07 to settle the wager in Simon's favor.

Here is that check…please note, that Ehrlich is such a POS that he had HIS WIFE sign the check!

Well humans obviously know better than nature so we will continue to try to “fix” things. Fidiocy!

Bkmrk

[TheDon]

Wait, scientists are still learning how the temperature of the earth is regulated?

I thought it was settled science!

[dadfly]

lol.

‘money for nothing and your chicks for free...’

[boycott]

MIT or AOC? I think I’ll go with MIT.

The “settled science” is the method for getting gullible fools to willingly part with their money and their freedom. That process they have down to a true science.

[rdl6989]

But the science was settled?????

[1FreeAmerican]

Absolutely!

is a drop in the bucket compared to volcanic eruptions, comet and asteroid strikes.

GOD said his creation was good. It is guaranteed to last until the end of time.

see thread The Book That Incited a Worldwide Fear of Overpopulation ‘The Population Bomb’ made dire predictions—and triggered a wave of repression around the world

And Over-engineering in nature: an evolutionary conundrum

[packagingguy]

Probably it’s form alkali earth elements present in many silicates forming carbonates upon weathering. Just a guess.

[joshua c]

doesnt matter

they will still declare a climate emergency

duuuuuuuuhhhhhhhhhhh

“....but I do believe that like as the human body has been over-engineered - by the Omniscient omnipotent Engineer - so has the earth.”

Some years ago I met Dennis Prager at a party the topic of the Earth being engineered came up. There seems to be design to the system. There have been enormous perturbing events like comet strikes of super volcano eruptions but the Earth has always rebounded. Other things that I mentioned in another thread is that carbonates are broken down when subducted into the mantle. If not there would be no carbon in the biosphere at all. The list goes on.

Natural systems are infinitely complex and the simple minds that propose the ridiculous schemes like carbon capture of injecting aerosols into the atmosphere have no concept of unintended side effects. They are one-factor thinkers where there is no cost to the imaginary benefits. This is how all liberals think on other matters as well.

I read a couple of years ago Alston Chase’s “Playing God in Yellowstone” and one of his observations was that environmentalists know nothing about the environment. That has been my observation as well.
