This is an especially pertinent finding given the flooding in the U.K., but, pertinence aside, it is yet more cause for concern, and for what ought to be global mobilization:
Human-induced climate change has affected global rainfall patterns over the 20th Century, a study suggests.
Researchers said changes to the climate had led to an increase in annual average rainfall in the mid-latitudes of the Northern Hemisphere.
But while Canada, Russia and northern Europe had become wetter, India and parts of Africa had become drier, the team of scientists added.
The specifics:
The team estimated that human activity, such as burning fossil fuels, was likely to have led to a 62mm increase in the annual precipitation trend over the past century over land areas located 40-70 degrees north, which includes Canada, northern Europe and Russia.
They also suggested the increase of greenhouse gases and sulphate aerosols in the atmosphere had contributed a 82mm increase in the southern tropics and subtropics (0-30 degrees south), and a 98mm decrease in precipitation in the northern tropics (0-30 degrees north).
The term for this sort of human activity is anthropogenic forcing. We're very good at it. Which means we're very bad for our planet.
