WHAT’S THE BIG DEAL?
Heating Planet
Thinning Ice
Rising Sea Levels
Encroaching Tides
The average global temperature on Earth has increased by about 1.4° Fahrenheit since 1880.
In recent years, the amount of ice replaced in the winter has not been sufficient to offset summer ice losses.
Sea level rise is caused primarily by two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms.
Longer term, the crucial issue is probably not how much the oceans are going to rise, but how fast.
Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.150.20°C per decade.
Between 2004 and 2008, multi-year ice cover shrank 1.54 million square kilometers (595,000 square miles) -- nearly the size of Alaska’s land area.

Coastal flooding will grow more frequent and damaging. (http://nyti.ms/1Oxn6qh)
