A record-smashing hurricane season in the central North Pacific. Water rationing in Puerto Rico. The biggest one-year jump in atmospheric carbon dioxide concentrations. These and more of 2015's extreme events had one thing in common: El Niño.
With El Niño in the rearview mirror, the central tropical Pacific continued to cool in June 2016.
A deep pool of cool water that had been lurking beneath the surface of the eastern tropical Pacific in April began to emerge at the surface in May 2016.
After a severe coral bleaching event struck the Great Barrier Reef, what does a future of climate change mean for the reef?
One reason the Fort McMurray area was at high risk for an early-season forest fire was that April snow cover was well below average in much of western North America.
Beneath the surface of the tropical Pacific, a deep pool of cool water has been sliding slowly eastward. This massive, slow-motion wave is a favorable sign that La Niña might develop.
A massive wildfire in northern Alberta has grown out of control, causing the evacuation of Fort McMurray, a city of 80,000 people. What climate conditions fostered this unusual early-season fire?
Unusually warm water along Australia's Great Barrier Reef has led to record-breaking coral bleaching.
Compared to March, parts of the tropical Pacific showed signs of cooling off in April 2016.
Drought has gripped many islands across the Pacific thanks to El Niño and a lack of rainfall.
