With Senators Barbara Boxer (D-Calif.) and Frank Lautenberg (D-N.J.) citing Hurricane Sandy as a reason to have another go at climate legislation, to say nothing of the media spin depicting Sandy as punishment for our fuelish ways, it’s useful to look at some actual science.
In a study published in the journal Climatic Change, scientists Michael Chenoweth and Dmitry Divine analyze the history of tropical cyclone activity in the Lesser Antilles from 1638 to 2009. The Lesser Antilles are the string of islands lying along the eastern Caribbean Sea.
The Lesser Antilles intersect the “main development region” for Atlantic hurricane formation, making storm data there “our best source for historical variability of tropical cyclones in the tropical Atlantic in the past three centuries,” the researchers explain.
Using instrumental data on wind speeds going back to 1900 plus wind-force and wind-induced damage reports for earlier periods, Chenoweth and Divine estimate the Lesser Antilles Accumulated Cyclone Energy (LACE) for each year along the 61.5°W meridian from 18 to 25° N latitude.
Storms forming in this area include most that do or could make landfall in the U.S. In the researchers’ words: “About 60% of all tropical cyclones moving from waters off of Africa pass through 61.5°W south of 25.0°N, the remaining 40% either moving north of 25.0°N, dying out or re-curving to the east of 61.5°W.” Chenoweth and Divine note that LACE is “highly correlated” with Carribbean basin-wide Accumulated Cyclone Energy (ACE) since 1899.
So what did they find? In their words: “Our record of tropical cyclone activity reveals no trends in LACE in the best-sampled regions for the past 320 years. Likewise, even in the incompletely sampled region north of the Lesser Antilles there is no trend in either numbers or LACE.” [click to continue…]
A favorite doomsday scenario of the anti-carbon crusade hypothesizes that global warming, by melting frozen Arctic soils on land and the seafloor, will release billions of tons of carbon locked up for thousands of years in permafrost. Climate havoc ensues: The newly exposed carbon oxidizes and becomes carbon dioxide (CO2), further enhancing the greenhouse effect. Worse, some of the organic carbon decomposes into methane, which, molecule for molecule, packs 21 times the global warming punch of CO2 over a 100-year time span and more than 100 times the CO2-warming effect over a 20-year period.
The fear, in short, is that mankind is fast approaching a “tipping point” whereby outgassing CO2 and methane cause more warming, which melts more permafrost, which releases even more CO2 and methane, which pushes global temperatures up to catastrophic levels.
In a popular Youtube video, scientists flare outgassing methane from a frozen pond in Fairbanks, Alaska. A photo of the pond, with methane bubbling up through holes in the ice, appears in the marquee for this post. Are we approaching the End of Days?
New York Times science blogger Andrew Revkin ain’t buying it (“Methane Time Bomb in Arctic Seas – Apocalyplse Not,” 14 Dec. 2011), nor does his colleague, science reporter Justin Gillis (“Artic Methane: Is Catastrophe Imminent?” 20 Dec. 2011).

Al Gore’s film An Inconvenient Truth bombarded audiences with image after image of hurricanes, tornadoes, floods, forest fires, and drought, creating the impression of a world in climate chaos. Gore blamed the alleged upsurge in extreme weather on global warming, that is, mankind’s sins of emission. One of Gore’s mighty pieces of evidence was a dramatic increase in insurance payments for weather-related damages. As he writes in his best-selling book of the same title:
Over the last three decades, insurance companies have seen a 15-fold increase in the amount of money paid to victims of extreme weather. Hurricanes, floods, drought, tornadoes, wildfires and other natural disasters have caused these losses [An Inconvenient Truth, p. 101].
Gore presented a chart similar to this one:
Seeing is believing, right? The problem, of course, is not merely that correlation (warmer weather/bigger losses) does not prove causation. More importantly, the economic data depicted in the chart have not been adjusted (“normalized”) to offset increases in population, wealth, and the consumer price index.

A study published today in Proceedings of the Royal Society reports that an extinct species of giant ant (Titanomyrma lubei, from the Greek word “Titan”) lived in Wyoming during the Eocene Epoch, about 50 million years ago. As colorfully described by Physorg.Com, the ant “had a body just over five centimeters long — comparable to a hummingbird — a size only rivaled today by the monstrously large queens of an ant species in tropical Africa.”

If you’ve been following the global warming debate for any length of time, you know how boringly predictable the “consensus” narrative has become. Global warming is good for bad things — poison ivy, ticks, toxic algae blooms, malaria-carrying mosquitoes — but bad for good things — polar bears, ski resorts, Vermont’s maple sugar industry, and the weather patterns on which agriculture (hence human survival) allegedly depend.
And supposedly, one of the cures for global warming is to “repower” America with zero-carbon energy, especially electricity generated from wind turbines.
But that creates a bit of a conundrum for warmists. If global warming is going to play havoc with the weather, how do we know that the best locations for siting wind farms today will remain optimal (or even marginally productive) in the allegedly topsy turvy greenhouse planet of tomorrow?
Never fear! A new study funded by the National Science Foundation finds that global warming will not significantly change America’s wind patterns over the next 50 years. [click to continue…]
