Nearly three-fourths of respondents agree that rising sea level resulting from climate change is a threat to the U.S., and 82% believe we should prepare for the effects.
Arctic breaks records for loss of snow and ice
A fast-changing Arctic broke records for loss of sea ice and spring snow cover this year, as well as summertime melt of the Greenland ice sheet, federal scientists reported Wednesday.
Is Shrinking Sea Ice Behind Chilly Spring?
Melting Arctic ice may be making winters colder and longer, scientists say.
Greenland ice sheet melted at unprecedented rate during July
The Greenland ice sheet melted at a faster rate this month than at any other time in recorded history, with virtually the entire ice sheet showing signs of thaw.
Hansen et al: “Extreme Heat Waves … in Texas and Oklahoma in 2011 and Moscow in 2010 Were ‘Caused’ by Global Warming”
“Climate dice,” describing the chance of unusually warm or cool seasons relative to climatology, have become progressively “loaded” in the past 30 years, coincident with rapid global warming.
Greenland and Antarctica melting faster than expected
The rate of melting by the ice sheets covering Greenland and Antarctica may throw existing projections for sea level rise out the window. Unfortunately for Maldivians and other idyllic, but altitude-challenged islands, the ice sheets are melting faster than anyone expected.
Global warming
The average global surface temperature of Earth has risen by .8 degrees Celsius since 1880, and is now increasing at a rate of about .1 degree Celsius per decade.
