Arctic Surface Waters Warm Without Insulating Ice Cap
Record-breaking amounts of ice-free water have deprived the Arctic of
more of its natural "sunscreen" than ever in recent summers. The effect
is so pronounced that sea surface temperatures rose to 5 C above average
in one place this year, a high never before observed, says the
oceanographer who has compiled the first-ever look at average sea surface
temperatures for the region.
NASA Satellites Help Lift Cloud Of Uncertainty On Climate Change
New findings from NASA's CloudSat and other spacecraft in NASA's
"A-Train" constellation of five Earth observing satellites offer
important insights into this year's record reduction of Arctic sea ice,
global rainfall patterns and the effects of pollution on clouds. The
investigations are giving scientists a greater understanding of factors
influencing Earth's present climate and an important foundation for
better understanding long-term climate change.
