Canadian climate sleuths have detected for the first time a human hand in the increasing fury of intense storms battering the Northern Hemisphere.
According to researchers, greenhouse gases generated by human activity have intensified heavy-precipitation events since 1950 across much of North America, Europe and Asia, increasing flooding and devastation.
“Human influence is more pervasive than just a response in surface temperature,” says Francis Zwiers, of the University of Victoria, referring to the rise in global temperature due to greenhouse gases.
He says human influence is now evident in the planet’s “hydrological cycle, and the behavior of the hydrological cycle.”
