I bet you, that those climate computer models do not reflect this self regulation capacity of our planet like so many other problems with this junk and propaganda models!
I also bet, these stabilizing feedback regulation exists at shorter time intervals than 100,000 years. They have yet to be found.
This article like many others goes to show how little we still know about the climate on earth! Thus, climate model forecasts of the development of the global climate up to 100 years into the future are preposterous if not charlatanry!
These research paper scientists could not resist to repeat that nonsense of "anthropogenic climate change". Scientists are all too human with all their faults and flaws!
"Now, a study ... 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. ...
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. ..."

Here is a very simplistic, naive, and misleading assumption by one of the authors of this study:
"“On the one hand, it’s good because we know that today’s global warming will eventually be canceled out through this stabilizing feedback,” says Constantin Arnscheidt, a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “But on the other hand, it will take hundreds of thousands of years to happen, so not fast enough to solve our present-day issues.” ..."
Or don't you love it when scientists try to explain new scientific discoveries in layperson terms (very slippery and probably erroneous!):
"...“To some extent, it’s like your car is speeding down the street, and when you put on the brakes, you slide for a long time before you stop,” Rothman says. “There’s a timescale over which frictional resistance, or a stabilizing feedback, kicks in, when the system returns to a steady state.” ..."
From the abstract:
"The question of how Earth’s climate is stabilized on geologic time scales is important for understanding Earth’s history, long-term consequences of anthropogenic climate change [???], and planetary habitability. Here, we quantify the typical amplitude of past global temperature fluctuations on time scales from hundreds to tens of millions of years and use it to assess the presence or absence of long-term stabilizing feedbacks in the climate system. On time scales between 4 and 400 ka, fluctuations fail to grow with time scale, suggesting that stabilizing mechanisms like the hypothesized “weathering feedback” have exerted dominant control in this regime. Fluctuations grow on longer time scales, potentially due to tectonically or biologically driven changes that make weathering act as a climate forcing and a feedback. These slower fluctuations show no evidence of being damped, implying that chance may still have played a nonnegligible role in maintaining the long-term habitability of Earth."
Fig. 3. Temperature fluctuations and feedback mechanisms.
(A) Root mean square temperature fluctuations ΔTrms as a function of time scale Δt (Materials and Methods) for five different paleotemperature time series and three nonoverlapping segments of the data from (36). Power-law scalings with fixed exponents H are shown as guides for interpretation. On time scales below about 4 ka and above about 400 ka, fluctuations behave similarly to the random walk (H ≃ 0.5; Eq. 1). In contrast, fluctuations do not grow with time scale in the intermediate regime, suggesting that stabilizing feedbacks were dominant here. The peak at ∼30 ka in the Plio-Pleistocene data (blue) and the strongly decreasing regime beyond it are likely signatures of glacial-interglacial variability. (B) Approximate time scales of relevant Earth system processes (see Materials and Methods for details). The symbols + and − indicate positive (destabilizing) and negative (stabilizing) feedbacks, respectively. The land ice sheet feedback is colored blue to emphasize that it is primarily relevant only after the onset of Northern Hemisphere glaciation ∼3 Ma ago.
