Climate oscillation

Changes come about in different ways. Gradually, over the long term. Or suddenly, with "events, dear boy, events," whose proportions we sometimes define as "historic." Or changes happen through the regular back and forth of real life, or by oscillations, sometimes in multi-decade cycles. Changes occur visibly or imperceptibly, sometimes going in opposite directions.

Scientists at the University of Michigan and the University of Arizona have come to this conclusion, quoted by NOVA TV. 

Global warming will accelerate in the future, scientists at the University of Michigan and the University of Arizona say, Science Daily reported.

AFP - Manmade global warming and a natural surge in Earth's surface temperature will join forces to make the next five years exceptionally hot, according to a study published Tuesday.

A new study suggests that an eruption of a large volcano in the tropics could cause El Nino to emerge, UPI said.

Last year's global weather was the warmest since modern record keeping began in 1880, a U.S. government report said Aug. 10.

The 27th annual State of the Climate report, prepared by more than 450 scientists from nearly 60 countries under the National Oceanic and Atmospheric  Administration's watch, said 2016 marked the third straight year of record warmth.

Scientists have known for a while that the Arctic is melting. The signs are everywhere—from the famed Alaskan Iditarod course being moved multiple times due to lack of snow, to the emergence of starving polar bears with nowhere to hunt.

But while scientists are certain that the Arctic is melting at an alarming rate, they aren’t really sure why.
