Cold this winter? Take another look at the Arctic Paradox

As another huge storm turns south towards the Midwest, some say that the cold winter can be explained by the Arctic Paradox, which links a natural phenomenon (the Arctic Oscillation) to a man-made phenomenon (diminishing ice in the Arctic), which combines to let polar winds escape southward. First question: Is ice in the Arctic really diminishing?  ThisContinue reading “Cold this winter? Take another look at the Arctic Paradox”

Global warming unpredictability: two stories

Global warming is not for the simple-minded, two stories from the same day last week remind us. As the invaluable Andrew Revkin notes on Dot Earth on 6/15, this past May was the warmest on record. On the same day, from a polar science conference in Oslo, researcher James Overland of NOAA presents evidence toContinue reading “Global warming unpredictability: two stories”

Battle of the Headlines: “World’s Ocean Temps Warmest Ever Recorded” vs. “Arctic Sea Ice Is Again on the Rise”

The first headline for USA Today, atop veteran science writer Seth Borenstein's story for the AP, was inspired by world-wide records from the National Climactic Data Center. As the story said: WASHINGTON — The world's oceans this summer are the warmest on record. The National Climatic Data Center, the government agency that keeps weather records,Continue reading “Battle of the Headlines: “World’s Ocean Temps Warmest Ever Recorded” vs. “Arctic Sea Ice Is Again on the Rise””

Denier “Science”: How to Miss the Forest for the Trees

At the ever-entertaining Watts Up With That, well-known global warming skeptic Roger Pielke Sr. links to the following graph: In a challenge to a NASA/GRL study released last week that shows a sharp decline in Arctic sea ice coverage, Pielke Sr. writes: Since 2008, the anomalies have actually decreased. No, I'm not kidding! That's hisContinue reading “Denier “Science”: How to Miss the Forest for the Trees”

Arctic Ice Trends Sharply Downward: Few Notice or Care

It's frankly shocking to me how many people I encounter who still cling to the idea that the globe is not warming, despite vast scientific libraries of evidence to the contrary. Here's the latest example, from data compiled by NASA and ICESAT: For more, see NASA's story New NASA Satellite Survey Reveals Dramatic Arctic SeaContinue reading “Arctic Ice Trends Sharply Downward: Few Notice or Care”
