Nenana Ice Classic – closing in on all time record latest ice-out
According to the ice breakup log, the latest the ice has ever gone out was May 20th, 1964 at 11:41 AM Alaska Standard Time. As of this writing there is about 28 hours to go to break that record. Geophysicist … Continue reading
Good news: World’s biggest ice sheets likely more stable than previously believed – upsets previous estimates of melting and sea level
Researchers show that high ancient shorelines do not necessarily reflect ice sheet collapse millions of years ago From the Canadian Institute for Advanced Research: For decades, scientists have used ancient shorelines to predict the stability of today’s largest ice sheets … Continue reading
Arctic methane emergency called off?
Here’s the issue, as described in Wikipedia: The Arctic region is one of the many natural sources of the greenhouse gas methane. Global warming accelerates its release, due to both release of methane from existing stores, and from methanogenesis in … Continue reading

New NSF paleo research claiming Arctic was warmer fails to take major ocean circulation changes 3 million years ago into account
I covered this story earlier today, and it was presented much differently in that press release. This press release takes a different tack. IMHO, it looks like a big “ooops” from the National Science Foundation. See what I found after … Continue reading
More ‘ice free Arctic’ claims – we’ve heard it all before
