Reviving the Voyage for Madmen

Last week, we saw The Mercy, a movie about Donald Crowhurst, the amateur sailor who lost his mind and his life in the first Golden Globe single-handed non-stop race around the world in 1968/69. The story of the nine men who took part was first told in an excellent book by Peter Nichols titled A Voyage for Madmen.

Arctic air, ice and temps: a sea change?

Yesterday I wrote about sea levels rising faster than predicted. Today, I'm going to summarize the latest in climate change anomalies. Scientists have recorded a warm air intrusion through the central Arctic this winter. In the area north of 80 degrees latitude, average temperatures were 36 degrees above normal. Whereas there were only four such intrusions between 1980 and 2010, there have been four occurrences in the past five years.

Sea level rise is accelerating

A new study by NASA's Sea Level Change team published February 12 in the journal Proceedings of the National Academy of Sciences has shown that sea levels are rising at accelerating rates rather than a steady increase as previously thought. That means that by 2100, the levels will be twice as high as previously predicted, causing serious problems for many coastal cities. If the rate of ice melt continues at this pace, sea levels will rise 26 inches (65 centimeters) by 2100. That's a lot more than shown in the graphic above.
