Climate change skeptics, including the communications director for the Republican minority in the Senate Environment and Public Works committee, have seized upon the unusually cold winter in North America as evidence that global warming is not really happening. There is no doubt that this year’s La Niña has led to cooler winter weather over North America than we have seen for the past decade (see figure from NYT: 1980-2008 trend), but even this cooler weather is above the 1960-1990 monthly winter average.

Published March 27, 2008 Climate change news , Science_Readings Leave a CommentThe World Glacier Monitoring Service in Zurich, Switzerland reports accelerating glacier melt based on 30 glaciers in 9 mountainous regions. The biggest worry is loss of glaciers in regions that rely on them for summer drinking water and hydroelectric power, such as those on the western slope of the S. American Andes. The full technical report is here. A quote from the final remarks section, regarding melt rate since 1980: “The melt rate and loss in glacier thickness continues to be extraordinary. This development further confirms the accelerating trend in worldwide glacier disappearance, which has become more and more obvious during the past two decades. “
One-fourth of the world’s species may vanish by the end of the century. There’s an effort afoot to preserve the diversity of the world’s crops by collecting seeds. Those seeds will go into the Svalbard Global Seed Vault now being built in Norway, above the Arctic Circle.
