The snowstorm in DC has nothing to do with my views, nor does the current weather in Vancouver (close to seasonal averages). <br /><br />I am more impressed by the implications of CO2 following rather than preceding temperature changes in the ice core data, grossly faulty approaches to computer modeling used by climate modelers, studies showing that solar effects on climate cannot be ignored, recent work undercutting the idea that CO2 creates positive feedback effects on other greenhouse gasses (necessary if CO2 is to cause harmful warming), and the now abundant documentation that the claims of recent warming have been based on faulty, even fraudulent data, to name but a few reservations I have about global warming theory. <br /><br />However, it is interesting to see how some believers in global warming (but not M. Tobias) have tried to force fit an unusual winter storm in DC into being a result of "global warming" despite snow in DC at this time of year requiring lower than average temperatures.Unknownhttps://www.blogger.com/profile/16869416166119261695noreply@blogger.comtag:blogger.com,1999:blog-8524070301101240472.post-9736835993915133122010-02-14T18:39:31.812-08:002010-02-14T18:39:31.812-08:00Its gonna snow in DC tomorrow and its gonna be abo...Its gonna snow in DC tomorrow and its gonna be above freezing.

It was a direct quote from climate "...Michael,<br /><br />It was a direct quote from climate "scientist" Viner that snowfall would become a rare and exciting event, not a journalist. Viner is further directly quoted as saying "Children just aren't going to know what snow is." Viner's imprecision as to when "a few" years is his, but the remark was made ten years ago. Bastardi's on-target prediction of this winter's weather was made last October and was specific to this winter. Again, Bastardi is no believer in global warming and he has an outstanding record of correct predictions. <br /><br />You think Viner's ridiculous remarks are unusual for believers in global warming?

" On this point I will only say that ...Glenn,<br /><br />" On this point I will only say that when angry feeling escapes from behind the intellect, where it may be useful as an urging force, and places itself athwart the intellect, it is liable to produce all manner of delusions. Thus my censors, for the most part, have levelled their remarks against positions which were never assumed, and against claims which were never made. "<br /><br />- John Tyndall, 1881<br /><br />Nobody has ever claimed that every year would be warmer than the last, and certainly not everywhere. <br /><br />It happens that so far, this year is on track to being the warmest ever, so even on that score you have a problem.<br /><br />The only source you quote as an example of excess is a newspaper article which neglects to define "few" years. What journalists say is (in some ways quite unfortunately) outside the control of scientists. <br /><br />If the exaggerations and handwaving of that Independent article are put up against the same features of recent articles about the CRU emails, though, that article smells like a rose.<br /><br />But basically your whole contribution is a strawman.Michael Tobishttps://www.blogger.com/profile/08229460438349093944noreply@blogger.comtag:blogger.com,1999:blog-8524070301101240472.post-42583248784608708622010-02-13T20:41:47.799-08:002010-02-13T20:41:47.799-08:00The snowfall this winter does have implications fo...The snowfall this winter does have implications for the credibility of global warming theory. For many years those who believe in global warming have been asserting that each year would, on average, be warmer than the last. This has led to many spectacularly wrong seasonal forecasts to be issued by believers in global warming, such as the U.K.'s Met Office. See:<br /><br />http://wattsupwiththat.com/2008/12/12/dr-roger-piekle-sr-on-uks-met-office-press-releases-on-climate/<br /><br />Other believers in global warming have been telling us for several years that we would see unmistakable signs of warming in our everyday lives. Note this forecast from 2000 from Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia, that within a few years winter snowfall will become "a very rare and exciting event".<br /><br />http://www.independent.co.uk/environment/snowfalls-are-now-just-a-thing-of-the-past-724017.html<br /><br />Meanwhile AccuWeather's Joe Bastardi, a strong dis-believer of anthropogenic global warming, was right on target in predicting a cold and snowy winter in the East back in October. See:<br /><br />http://www.skisoutheast.com/articles_2747_Accuweathers-20092010-Winter-Forecast-Predicts-a-COLD-and-SNOWY-Winter-for-the-Southeast-and-Mid-Atlantic.html?archived=false&type=all&subtype=firsttrax<br /><br />Whose long-term climate forecasts do you want to believe - those who can get short-term predictions right or those who can't even predict out a few months at a time? <br /><br />I am fully aware that there are many complexities in evaluating a theory such as global warming. I do not believe in it because I see it as scientifically flawed in many ways, irregardless of a given snowsorm in DC or anywhere else.<br /><br />However, since proponents of the theory have for years been using all sorts of events as "evidence" of global warming (alleged increase in hurricanes, pine beetle infestations, the crash of Air France Flight 447, etc.) I am amused to see them now claim that a massive snowstorm in DC in February (where temperatures average above freezing this time of year) fully fits with global warming theory. If both more snow and the cold temperatures needed to produce snow and less snow and warmer temperatures all go along with global warming then the theory is one that cannot be falsified and is hence non-scientific.Unknownhttps://www.blogger.com/profile/16869416166119261695noreply@blogger.comtag:blogger.com,1999:blog-8524070301101240472.post-80255714862685866462010-02-13T17:49:05.028-08:002010-02-13T17:49:05.028-08:00I was going to comment on the pink noise view of n...I was going to comment on the <b>pink noise</b> view of <i>natural variability</i>, but it seems more urgent to show off BPL's decadal average anomalies from the GISTEMP global temperature product:<br />1880s -0.25<br />1890s -0.26<br />1900s -0.27<br />1910s -0.28<br />1920s -0.16<br />1930s -0.03<br />1940s +0.04<br />1950s -0.02<br />1960s -0.01<br />1970s +0.00<br />1980s +0.18<br />1990s +0.32<br />2000s +0.51<br />Do note that the last 30 years were noticably warmer than the prior 30 and that the decade-upon-decade trend remains starkly upwards.David B.

That all seems quite equivocal to me.
The ...Bob,<br /><br />That all seems quite equivocal to me. <br /><br />The Chagnon article just tries to extract trends from a noisy record, and does not include the ENSO correlation. And the Masters article seems to jump from northward retreat of storms (which would take them away from the mid-Atlantic) with possibly more severity (and more lake effect snow in the midwest, which makes perfect sense to me) to supporting the idea that the likelihood or intensity of these storms is anthropogenically enhanced. <br /><br />The Chagnon observations do not support a trend in the east or the northeast (figure 7) and figure 6 shows lake snows increasing and a perhaps noise-driven increase in the west, but if anything a decrease in synoptic scale blizzards in the east.<br /><br />So I don't understand the appeal to Chagnon.<br /><br />And the Masters note seems strange to me. He also talks about northward retreat, and more lake effect snows, and then somehow waves the noreasters into the picture. Again, I don't get it. <br /><br />Anyway, as Nielsen-Gammon said, maybe. The suggested trend toward more noreasters isn't excluded. But it seems like a stretch to me. I don't see it in the data you point to and I don't see it in the theory of retreating jet streams. It's not a solid consensus view at present and in my opinion shouldn't be played as one.<br /><br />To the extent that a dynamical explanation beyond bad luck is needed, ENSO provides it. So what is the point in walking into this?<br /><br />It's interesting, by the way, to see the impressive positive anomaly of blizzards in the east and northeast during the "global cooling scare" which is smaller or absent in the other regions.<br /><br />I think bringing Katrina etc. into climate debate was possibly justifiable as a "load the dice" argument, (I find the Srivers and Huber argument in favor of increased tropical activity in hot earths quite compelling) but the blizzards are not, not until someone comes up with a strong argument of how the dice are loaded.<br /><br />In short, I stipulate that midlatitude storms will be wetter but I would think that the rain/snow line will move north; the balance of these forces is not obvious. This would not provide a compelling argument for the likelihood of the current snow across the middle south and mid-Atlantic. On the other hand, El Nino moves the snow line south, and would.Michael Tobishttps://www.blogger.com/profile/08229460438349093944noreply@blogger.comtag:blogger.com,1999:blog-8524070301101240472.post-46960183525404439222010-02-13T05:29:30.584-08:002010-02-13T05:29:30.584-08:00Yes, with some qualifiers about regions, they are....Yes, with some qualifiers about regions, they are.
