Re: [geo] Re: Sea Ice Stephen is right on three counts: water flows a great distance before freezing even at very cold ambient temperatures, northerners have long experience of both keeping water flowing and dealing with frozen pipes, and frozen pipes are readily thawed in the presence of

I¹m a bit baffled (and late in responding. The sea water temperatures are typically very near freezing. The idea might work in the fall but I don¹t see how it works the rest of the year (ocean temperatures too near freezing in the winter; air temperatures too high in spring and summer). Mike On

Arctic sea ice heading for new record low "In April, the centre published data showing that sea ice had almost recovered to the 20-year average. That ignited a flurry of interest on climate change skeptic blogs. But much of that ice was thin and new. The warmest April on record in the Arctic made

Time for a reality check. It has been the slowest July Arctic melt in the eight year JAXA record . Ice extent has declined at less than half the rate of 2007, and

The article you/Ken cited is about methane capture. It is not a research paper supporting the statement "we can expect permafrost to release large quantities of methane, from as early as 2011 onwards" I don't understand your use of the word arrogant. The danger of climate change may exceed the s

Hi All Did Glyn miss Boucher and Folberth, Atmospheric Environment 44 (2010) 3343–3345 which Ken circulated earlier this week? Is the track record of prediction accuracy of climate scientists high enough for us to bet the planet on them always being correct? The best ones that I know are n

You say "The Arctic warming is now accelerating, and we can expect permafrost to release large quantities of methane, from as early as 2011 onwards, which will lead inexorably to runaway greenhouse warming and abrupt climate change." However in a 2007 review of scientific papers [1] it concluded t

It's impossible to *prove* S = 1. In fact, coaxing the Earth out to a higher orbit might work, but that's not something we could conceivably do. Meanwhile an undiscovered 'practical solution' doesn't help us, and there are probably a lot of people scratching their heads looking for one. I'm not

Two comments on the letter proposal... 1. "Only a few scientists predicted this event for the coming decade, and they were ridiculed". This sour grapes statement does not strengthen a case for geoengineering. Then 'many more' scientists now agree with the more severe assessment -- that implie
