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.

“For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.” Exodus 20:11

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.

Scientists have long suspected that silicate weathering plays a major role in regulating the Earth’s carbon cycle. The mechanism of silicate weathering could provide a geologically constant force in keeping carbon dioxide — and global temperatures — in check. But there’s never been direct evidence for the continual operation of such a feedback, until now.

The new findings are based on a study of paleoclimate data that record changes in average global temperatures over the last 66 million years. The MIT team applied a mathematical analysis to see whether the data revealed any patterns characteristic of stabilizing phenomena that reined in global temperatures on a  geologic timescale.

They found that indeed there appears to be a consistent pattern in which the Earth’s temperature swings are dampened over timescales of hundreds of thousands of years.

  1. I don’t understand how you can post articles with numbers like 100,000 years and 3.5. billion years of history. Doesn’t our bible tell us the earth is 6,000 years old with one more thousand years to go in the Millennial Kingdom? Are those numbers found in the bible? I can’t find them!

    • Thank you for responding. The article you bring up is from MIT and I wanted our readers to see secular Godless thinking from one of our most prestigious academic institutions. What I tried to do is use 2 Bible verses to completely discredit the entire article without writing an opinion post and maybe it didn’t work. I get what you are saying and will consider trying it a different way next time perhaps with an assessment either before or at the end of the article.
