Scientists in the United States have found that the global temperature has been increasing for the last 12,000 years, a fact that helps to clarify the climatic changes during the Holocene, according to a study published in the journal "Nature".

The authors explain that previous studies have developed reconstructions of historical temperature variations from geological materials, an approach that suggests that a maximum temperature peak was reached about 6,000 years ago, followed by a decline until the industrial period.
However, they point out, these reconstructions are in contrast to the investigations carried out from long-term climate models, which indicate that there was continuous warming throughout the period.
According to the expert, the warming that occurred during the "late Holocene was, in fact, caused by the increase in greenhouse gases", as "predicted by climate models." "This removes any doubt about the key role that carbon dioxide has on global warming," emphasizes Bova.
Evolution of Temperature
The evolution of temperatures during the last interglacial period and the Holocene has divided the experts, since the data provided by some studies suggest that the global annual average temperature during the current period has not reached the level of the so-called “Holocene thermal maximum", which was followed by a global cooling. However, climate models indicate with "very solid" evidence, that global temperature has been increasing over the last 12,000 years.
Experts recall that current temperatures are the highest in the last 12,000 years and similar to those recorded during the last interglacial period, about 125,000 years ago. "We have found," adds Rosenthal, "that post-industrial warming has accelerated the long and constant warming trend that has occurred over the last 10,000 years."
