A trend that was nipped in the bud by human action. This is the main conclusion of a study that has just been released by the specialized journal Nature Geoscience , carried out by an international team of scientists.
The report is based on data from 57 reconstructions of ocean temperatures in the past. And what was the reason for this refrigerant phenomenon? Well, climate models suggest that only a succession of volcanic eruptions could produce it. Neither the changes in solar activity, nor the Earth's orbit, nor the crops, nor the greenhouse gases of those times explain it.
Although the water in the oceans has a greater capacity to conserve heat than the landmass, if many eruptions occur in a short period of time, then the change in temperatures ends up also affecting the liquid part of our planet .
"Today, the Earth heats up 20 times faster than it cooled during the 1,800 years before the 19th century, " explained geologist Michael Evans, one of the study's authors. "This research highlights the profound changes that the climate is undergoing today."
