Climate Science, To The Edge Of Irrelevance

After days of extremely-silly reports trying to argue that a warming world means a colder world or part of it, as if a winter or two meant anything in the context of climate (usually defined as a 30-year average), a ray of hope for the serious parts of climate science has shone at DotEarth. After all, whenever a rabid warmist claims success after having fished around for any instance of weather extreme anywhere in the world, it’s hard to tell the ensuing climate looting from any claim about Nostradamus.

The whole brouhaha about the cold weather of December 2010 actually highlights three issues that are pushing climate science towards irrelevance:

  • If somebody like Judah Cohen publishes a NYT Op-Ed focused on explaining how to “reconcile” the “snow and record cold” with “a World Meteorological Organization report showing that 2010 will probably be among the three warmest years on record“, then what exactly are climate projections for?

As every newspaper reader outside of North Korea should know by now, a warmer world is expected to be a world perhaps with more snow, perhaps with less snow, perhaps with both; perhaps with more floods, perhaps with more droughts, perhaps with both; perhaps with more cold, perhaps with more heat, perhaps with both…That covers more or less every possibility, apart from “no change at all”, hence it is similar to expecting at the roulette table any number between 0 and 14 and between 16 and 36, having seen “15” come out several times in a row. There is no need of peer-review or statistical analysis to do that. There is not even any need to model the roulette wheel and its pockets. And as any trip to the Casino can show, there is no reward at all in betting upon such an extremely-wide-ranging set of “projections”.

  • In a new blog, Revkin mentions “Jay Fein, program director in N.S.F.’s climate dynamics program” as saying “weather impacts peoples’ lives and the global economy on a daily basis

Why then should anybody care about 30-year averages? What is the meaning of spending considerable resources to mitigate or even adapt to some hard-to-tell thing that might or might happen in 2050AD when the impact of atmospheric patterns is felt “on a daily basis“? Imagine asking anybody in 1900 to put aside money for good use in 1940…

  • And even if one willingly forgets the two objections above…as mentioned here already a few weeks ago, and independently reaffirmed at Real Science, the very concept of a “global anomaly” by which we can measure a “warming planet” might be meaningless, as an unevenly-warming world might see everybody having to face a life of cold

Imagine if a cold place where the average temperature is -20C warms by 4C, and a temperate place where the average temperature is 10C cools by 2C. Obviously the resulting “average anomaly” is +2C and people can run around screaming about “global warming”. Apparently logical…and yet: the result is that people will have a choice between living at -16C or leaving at 8C, i.e. between where it’s still as cold as ever, and where it’s not warm enough any longer.

In such a situation, as in trying to build an effective policy from an extremely-wide range of expected scenarios, and as in trying to convince the people of today to suffer for something that we don’t know and might or might not happen far in the future, politicians actively applying what contemporary climate science tells them will find themselves victims of unintended consequences at best, and of complete misleading at worst. The most likely outcome? Nobody in their right mind will ever listen to a climate scientist again…

    I guess the AGW enthusiasts could always blame the Northern Ireland problem on the thaw – obviously caused by global warming!

    As usual, the UK serves as a dire example. Captivated by the Met Office’s “unmistakeable signs of a warming world”, this country is gearing itself up to deal with sweltering summers in the year 2080, meanwhile fails to learn the lessons from a few months ago, orders less road salt than it did last year, and gets clobbered again by “weather, not climate”.

    Now there is an acute and dramatic water shortage in Northern Ireland, and the cause? Not a drought brought on by global warming but by ice thawing, pipes bursting and draining the reservoirs.

    The image that comes to mind is that of a person scanning the distant horizon for dangers, then tripping over a rake in his own back garden.
