Arctic Ocean changes driven by sub-Arctic seas
New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.
Ice melting Arctic cyclones more common than previously thought
Remember the Arctic cyclone that chopped up the Arctic sea ice in 2012, resulting in a new record low summer extent for the satellite era? It turns out they are rather common. From the AGU Fall Meeting and the Ohio State University Data analysis reveals hundreds of storms — mostly smaller ones — that had…
A Theory Ready for Extinction
Don’t worry too much over those warmist predictions that millions of species will soon be lost to climate change. Judging by their methods it is the doomsayers who are the real dodos Guest essay by Dr. David Stockwell Will climate change really cause species extinctions? It’s not a simple question to synthesise the connections between…
Negative feedback? Storing CO2 in the Arctic
From the Massachusetts Institute of Technology: While the Arctic Ocean is largely a carbon sink, researchers find parts are also a source of atmospheric carbon dioxide For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent…
NASA says Arctic sea ice 'Unlikely To Break Records' in 2013
A video animation follows. Note also that Dr. Walt Meier is now with NASA Goddard, after leaving NSIDC at the end of July. This is his first report from NASA. – Anthony Arctic Sea Ice Update: Unlikely To Break Records, But Continuing Downward Trend The melting of sea ice in the Arctic is well on…
Remarkable correlation of Arctic sea ice to solar cycle length
This is interesting, especially since Solar Cycle 23 was quite long. The Hockey Schtick writes: A paper published by the Danish Meteorological Institute finds a remarkable correlation of Arctic sea ice observations over the past 500 years to “the solar cycle length, which is a measure of solar activity. A close correlation (R=0.67) of high significance (0.5…
Avaaz! Save the world from a slushy death, just £2
People send me stuff. This is an email solicitation claiming that if you send Avaaz £2 a week (About $3.07 USD at current exchange rate) they’ll somehow be able to help NSIDC’s Julienne Stroeve get started putting back that Arctic ice, much like as a previous subscriber, you may have given money to help dolphins from…
Modeling sea level rise is an 'uneven' proposition
From the British Antarctic Survey New projections of ‘uneven’ global sea-level rise Reporting in the journal Geophysical Research Letters researchers have looked ahead to the year 2100 to show how ice loss will continue to add to rising sea levels Sophisticated computer modelling has shown how sea-level rise over the coming century could affect some…
Ice loss model verification via satellite observations
European satellite confirms UW numbers: Arctic Ocean is on thin ice By Hannah Hickey (via university of Washington press release) The September 2012 record low in Arctic sea-ice extent was big news, but a missing piece of the puzzle was lurking below the ocean’s surface. What volume of ice floats on Arctic waters? And how…
Dust in the wind: Melt ponds in the Arctic hasten overall melting
I’ve often wondered if carbon soot plays a role in this. See our recent WUWT story about how black carbon’s role has been underestimated, and note that Arctic melting is listed as one of the effects. See also the tag I’ve added to the story at the bottom about what melt ponds start out as:…
