Curmudgeon,
There's non-so blind as them as does not want to see. I wonder what you would be saying about global warming as the sea gets up over the coast in about 50 years time and the temperatures are getting up to the high 50s C, making life untenable in most of the earth. I expect that it will be something like " It's all cyclical and anyway it is not really happening”. Denialist to the end. Posted by sarnian, Thursday, 7 October 2010 11:27:48 AM

Sarian - its the other way round. How many years of temperatures not doing much and sea levels failing to move much at all - as clearly shown by the measurements - will it take for the global warmers to admit that their alarmist warnings are, at the least, oversold?
Already the debate has cooled noticeably (pun intended) after the climategate emails and the various IPCC scandals. But I suspect a decade from now, when the public has forgotten about global warming, just as they've forgotten about Millenium bug and the long gone scares over AIDS in Australia - which featured experts "certain" that disaster was imminent - hard core activists (including scientists) will insist that really the measurements are wrong and the earth is warming.

Gee, I wonder if this satellite is as reliable as the satellite which found that Lake Michigan was boiling away?
http://wattsupwiththat.com/2010/10/04/an-over-the-top-view-of-satellite-sensor-failure/ Every device goes wrong occasionally: but if a biased observer is in charge of the results it is all too easy for them to interpret 'going wrong' as 'going right'. We need more than one set of data, and more than one data custodian, to justify extraordinary claims. Posted by Jon J, Thursday, 7 October 2010 2:24:44 PM

"as the sea gets up over the coast in about 50 years time "
I suppose you would classify this one as "not being able to see the coast for the sea" Fear mongering and exaggeration will only harm you cause, which is.....? Posted by Stezza, Thursday, 7 October 2010 4:07:47 PM

curmugeon,
You obviously do not read posts thoroughly; you do not even get the name right: It’s sarnian nor sarian. The point I am trying to make is that if you are not right, it will be too late to attempt to do anything about climate change. I of course disagree with you about *How many years of temperatures not doing much and sea levels failing to move much at all - as clearly shown by the measurements - will it take for the global warmers to admit that their alarmist warnings are, at the least, oversold?.* It does not take a sensitive satellite to show how little ice there is in the Arctic during summer and the fact that ships can now make passages through the Northwest Passage with no difficulty. All around there are obvious signs of warming for anyone with an open mind . At the rate the Greenland icecap is melting, it is quite possible that one day quite soon there will be catastrophic collapse as has happened to several huge ice shelves and a large chunk will slide into the sea, Then I wonder if you will say “gee maybe we should have erred on the side of safety?” Posted by sarnian, Thursday, 7 October 2010 4:09:54 PM

This shows that ther was a slight increase in average global temperatures (less than the land station record shows) between 1975 and around the turn of the century, and nothing much happening since. Sea surface temperatures are also well known, and don't show what John wants (if they do, why not refer to them directly). However, cyclic changes in the currents probably do account for some of the artic sea ice melting.
A graph of Changes in sea levels measured directly can be found at http://sealevel.colorado.edu/results.php sorry, again, no great changes.. its running 3 mm a year (0.3 metres over a century) as it has for decades now - actually somewhat less in the past couple of years.
If you take another look at the figures, John has quoted impressive numbers but I suspect they do not add up to much on a world scale.
