The planet has its own stabilizing mechanism that has the ability to keep global temperatures in the optimal and habitable range, thus helping to bring the climate back from the brink.
Scientists have become interested in this phenomenon and have suspected that it is silicate erosion that plays an important role in regulating the planet’s carbon cycle.
The term “silicate weathering” points to a geological process by which the gradual and constant erosion of silicate rocks results in chemical reactions that in turn extract carbon dioxide from the atmosphere and deposit it in ocean sediments. In this way, the process traps the gas in the rocks.
The silicon erosion mechanism may be responsible for providing a robust and geologically constant force to keep global temperatures and carbon dioxide at optimal levels.
However, scientists still lack direct evidence to support this theory.
Scientists from the Massachusetts Institute of Technology (MIT), USA, confirm the presence of stabilizing feedback, the mechanism of which is possibly the erosion of silicates. This has been explained in the study published in the journal Science Advances.
What does stabilizing feedback say?
Stabilizing feedback speaks to the ways in which the planet has remained habitable through massive climate changes in the history of the planet’s geology.
What do the authors of the study say?
Constantin Arnscheidit, the author of the study, said: “On the one hand, it is good because we know that the current global warming will eventually be nullified through this stabilizing feedback. But on the other hand, it will take hundreds of thousands of years to happen, so it won’t be fast enough to solve our current problems. “
The idea has not been extremely novel. Scientists already had indications of the existence of a climate-stabilizing effect on the planet’s carbon cycle. The evidence? Well, ancient rocks have always been useful. When chemical analyzes were performed on these ancient rocks, it was found that the flow, or flux, of carbon in and out of the planet’s surface environment has remained relatively stable and balanced, despite dramatic changes in global temperature.
