El Niño is a periodic climatic phenomenon where waters of the eastern tropical Pacific warm, triggering a range of potential consequences for global weather.
Part of the wide range in estimates for when summer sea ice will disappear is due to uncertainty about how quickly the exposed darker sea will warm, triggering a cycle of more melting and warming.
Unprecedented and prolonged ocean warming triggered a global coral bleaching event that started in 2014 and may extend well into 20173.
Many small island states are predicted to be swamped by rising seas with global warming triggered by carbon levels as low as 400ppm.
This rate of loss is 50% higher than most scenarios outlined by polar scientists and suggests that global warming, triggered by rising greenhouse gas emissions, is beginning to have a major impact on the region.
And although researchers are still far from certain whether an anticipated increase in cloudiness will further heat up the planet or offset the warming a bit, a growing consensus among climate modelers is that clouds will increase, rather than hold back, the warming triggered by greenhouse gases.
Climate experts blame global warming, triggered by emissions from industries and cars, for much of the ongoing retreat of glaciers worldwide.
Without people fully understanding the complexities of the global climate, global warming triggers the right ideas.
The main reason appears to be a catalytic warming effect, triggered by global warming.
But, a sudden and brief warm period triggered American shad (Washington's favorite fish) in the nearby Schuylkill River to gather and spawn, immediately ending the famine.
