A kind of domino effect — a convergence of rising temperatures and changing precipitation rates occurred across the planet during the last ice age, stretching from 120,000–11,700 years ago.
According to a study published 21'st of august 2020 in the journal Science, climate changes in several areas of the world affected each other.
"By analyzing stalactite measurements from caves in South America, Asia, Europe and ice core samples from Greenland, we are able to see that 34 of the last ice age's 37 abrupt climate changes occurred simultaneously in each of these regions. In Greenland, abrupt warming caused temperatures to rapidly increase by roughly 20 degrees on 37 occasions during the last ice age, while other regions were particularly impacted by sudden changes in precipitation patterns," explains Sune Olander Rasmussen, an associate professor at the University of Copenhagen’s Niels Bohr Institute.
"While we don't completely understand what caused these climatic changes, they are most likely the result of changes to the strength of the Gulf Stream," elaborates Rasmussen.
