While we’ve had a number of unusual and anecdotal cold snaps in late summer in the northern latitudes, there are also warm events too. It will be interesting to see how this event is reported by newspapers and other media in the Bay Area. Perhaps we’ll get a firsthand report from Mosher.

RE: Caleb (20:13:45) :
SF City is a location in SF proper.
“San Francisco” (aka SFO) is San Francisco Int’l Airport, which is not in SF at all, it is in a suburban community – San Bruno.
Interestingly, under “normal” summer circumstances, SFO tends to run slightly cooler than SF City, due to its location downwind from the major fog / seabreeze gap between San Bruno Mountain and the Santa Cruz Mountains.

Why the sarcasm? This is a real worry and if this part of the globalwarming scenario is playing out then yes, we should all be worried. The arctic ice extent is now at its 2nd lowest point and is now on course to beat last years record ice melt http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm.
If this causes, as it seems it may be starting to do, rapid relaeases of atmospheric methane, then we could potentially be facing a mass extinction event. In case you think I’m being sensationalistic bear in mind that large relases of methane are the most probable cause of the Permian extinction event 250,000,000 years ago which wiped out approx. 90% of land and marine life. Just google ‘Permian extinction methane’ to get a feel of the subject.
@ur momisugly mary
the melt this and last year is unrelated to temperature, but has everything to do wind a change in wind direction, very strong northern winds push the ice south, thats why there`s also more ice around the island jan mayen.
Wetter models didnt predict it, well because they are wrong!
besides a eath without polar ice isnt unique at all, in its 4.5 billion years life time it has been iceless over 99 % of the time
So the methane doom exticion you are talking about is just complete nonsense, (there was no ice 250 million years ago) not even on antactica
We are in a iceage now thats has been getting colder and colder over the past 3 million years..

Please stop using untruths to try and justify your view, they are deliberately misleading and, to be honest, made up junk.
Why do you always use absolutes? The melt is known to be a combination of factors INCLUDING temperature, to say it is unrelated is frankly obsurd.
Your statement about the earth being without ice 99% of the time is also a lie, there have been ice caps for about 15% of the time, and ice on high altitudes for considerably more time.
Another lie when you say there was no ice 250 million years ago, this marks the end point of one of the major ice ages in earth history, the Karoo ice age (350-250 MYA). Immediately after this was a particularly rapid globalwarming event. There also may not have been ice on Antarctica as it was connected to Pangea at this time on the southern tip. The main reason why Antarctica is so cold now is because it is isolated at the south pole surrounded by the circumpolar currents.
I don’t know how you can say that it’s been getting colder and colder over the last 3 million years. We are either at the end of these cycles or at in interglacial period but the temperature during these cycles has been pretty similar at the top and bottom ends of the range.
Given the fact you have just made up virtually all that you said how can you present to the world your assertion that the methane doom extinction,as you put it, is complete nonsense?
