Updating their official stance on the relationship between climate change and weather events, the American Meteorological Society (AMS), has now stated plainly that the warming world is a fact beyond reproach and that human activity—despite some natural variability—is the main force behind such changes.

"Warming of the climate system now is unequivocal," the group said in a statement on Monday. "Observations show increases in globally averaged air and ocean temperatures, as well as widespread melting of snow and ice and rising globally averaged sea level."

The dominant cause of the warming since the 1950s is human activities, they said, adding that their scientific finding is based on "a large and persuasive body of research."
