Antarctica Melting
A team of NASA and university scientists has found clear evidence that extensive areas of snow melted in west Antarctica in January 2005 in response to warm temperatures. This was the first widespread Antarctic melting ever detected with NASA's QuikScat satellite and the most significant melt observed using satellites during the past three decades. Combined, the affected regions encompassed an area as big as California.
"Antarctica has shown little to no warming in the recent past with the
exception of the Antarctic Peninsula, but now large regions are showing
the first signs of the impacts of warming as interpreted by this
satellite analysis," said Steffen. "Increases in snowmelt, such as this
in 2005, definitely could have an impact on larger-scale melting of
Antarctica's ice sheets if they were severe or sustained over time."
