Hudson Air Crash Caused by Global Warming - NOT

Time Magazine ( I used to get Time every week and respected the articles found in it!) blamed the bird-strike that brought down an Airbus passenger aircraft in the Hudson River, New York, on "global warming".

Christopher Monckton on Right Side News put out a more realistic argument.

"The Time article said that "Wildlife mitigation" was the official term for avoiding bird strikes. A report published in June 1988 by the Federal Aviation Administration had found that since 1990 the number of bird strikes had quadrupled, from 1,759 in 1990 to a record 7,666 in 2007. According to Time, "Officials cite a number of possible causes for the increase", including "habitat destruction and climate change", which "have disrupted migratory patterns". Time adds, "Al Gore should be very proud of himself."
The truth: As the article also points out (though not in the headline), most commercial airlines are replacing three-engine and four-engine aircraft with twin-engine aircraft. The newer engines are quieter, so birds are less likely to detect and avoid them. Also, aircraft with fewer engines are less able to survive bird-strikes."

Lord Monckton lists the 7 worst fatalities due to bird strike. They occurred in Oct 60(Boston); Nov 62 (Maryland); Sept88 (Ethiopia); Apl90 (Off Panama); Sept95 (Alaska); Apl2000 (Congo); Jan07 (France).

"The geographical spread of the bird strikes shows that there is no basis whatever for the suggestion that "global warming" has aggravated the problem. Bird strikes have occurred in all parts of the globe, from the tropics to the Arctic, and they have involved birds of all kinds. Birds, like most species on earth, are necessarily tolerant of different climates. This tolerance of varying temperatures is essential to survival, since the temperature difference between a summer's day and a winter's night, in the same location, can be at least 100 times greater than the 0.74 °C (1.3 °F) difference between mean global surface temperature 100 years ago and today."

Another spurious article incorrectly attributing something unrelated to (anthropogenic) global warming?

"Al Gore, mentioned with approval in Time's article, complains in the entertaining fiction book that accompanies his inaccurate movie An Inconvenient Truth, that pied flycatchers can no longer hatch at the right time to feed their young on the customary species of caterpillar, which "hatch two weeks earlier after 20 years of ‘global warming'". He is careful not to point out that "global warming" has been happening not for 20 years but for 300. He is also careful not to point out that, even if the caterpillars were indeed becoming available a couple of weeks later in the year than previously, the birds would merely have to fly a few miles further north to find caterpillars that hatched at a more convenient moment.
