A study by NASA’s James Hansen and two colleagues, published Monday in Proceedings of the National Academy of Sciences (PNAS), finds that during the past 30 years, extreme hot weather has become more frequent and affects a larger area of the world than was the case during the preceding 30 years. Specifically, the study, “Perception of climate change,” reports that:

  • Cool summers occurred one-third of the time during 1951-1980 but occurred only 10% of the time during 1981-2010.
  • Very hot weather affected 0.2% of the land area during 1951-1980 but affected 10% of the land area during 1981-2010.

Hansen is the world’s best known scientist in the climate alarm camp and a leading advocate of aggressive measures to curb fossil-energy use. He and his co-authors are up front about the policy agenda motivating their study. The “notorious variability of local weather and climate from day to day and year to year” is the “great barrier” to “public recognition” of man-made climate change and, thus, to public support for policies requiring “rapid reduction of fossil fuel emissions.” When heat waves or drought strike, the authors want the public to perceive global warming. On Saturday, the Washington Post published an op-ed by Hansen summarizing the study’s results.

Heat waves will become more frequent and severe as the world warms; some areas will become drier, others wetter. Those hypotheses are not controversial. (more…)

UN CLIMATE PANEL AND “EXTREME WEATHER

The Intergovernmental Panel on Climate Change admitted last week it had no evidence to support the various claims that the planet’s weather is becoming “more extreme.” The new IPCC report on weather extremes reads: “While there is evidence that increases in greenhouse gases have likely caused changes in some types of extremes, there is no simple answer to question of whether the climate, in general, has become more or less extreme.”

Incredibly, even this non-confirmation is false. The more correct answer is “less extreme.” Moreover, paleoclimate proxy records have already told us about the truly awful climate extremes of the past 10,000 years—most of them mega-droughts during “little ice ages.” For example, the 300-year drought that beset today’s Iraq in 2200 BC. The inhabitants all starved, and the land was left to a few nomadic shepherds until the warm phase of the 1,500-year Dansgaard-Oeschger cycle returned stable weather. Then the Tigris-Euphrates Valley produced a new irrigated agriculture and built the world’s first cities. This valley’s devastation/recovery pattern has happened at least seven different times, in the D-O’s 1,500-year rhythm.

Nor did the IPCC mention the 11th century AD mega-drought in the northern California mountains, with lake levels falling 70 feet below “normal.” At the same time, the Anasazi and dozens of other western Indian tribes were driven from their homes forever. In the Corn Belt, the mega-drought destroyed Cahokia, Illinois, the only city the AmerIndians ever built.

What about the four huge sea-floods that attacked Northern Europe over a period of about 40 years in the 12th century? Whole counties were buried under storm sands and are still buried there! Each of these massive storms drowned more than 100,000 people. The biggest drowned 300,000, from a population of perhaps 75 million. If it happened today, with the present population density,  that number might be expanded to 3 million deaths.

The ship’s logs of the British Navy reveal twice as many major land-falling Caribbean hurricanes during the latter part of the Little Ice Age (1700–1850) as during the last half of the 20th century—when the planet was supposedly warming at an “unprecedented” rate. (more…)

The Worst NYT Story on Climate Ever?

Regular readers will know that I think that the print media overall has done a pretty good job on covering the science of climate change, if not always getting the politics right. They will also know what I think about the “debate” over climate change and extreme events (above). But every once in a while I see a story that is so breathtakingly bad that it is worth commenting on. Today’s installment comes from Justin Gillis at the New York Times and was published on Christmas Eve. The article is so bad that it might just be the worst piece of reporting I’ve ever seen in the Times on climate change.

Where to begin? How about the start. (more…)

The Cost of Political Pseudo-Science Shown In Two Examples

Tuesday, June 7th, 2011

Surely it’s time for climate-change deniers to have their opinions forcibly tattooed on their bodies.

- Richard Glover (HT:National Times.Com)

Richard Glover and Dr. Donald Brown are two very different men, in different nations, who work towards a common goal. Each man believes that human pollution has driven a series of chemical and physical changes in the Earth’s atmosphere. Each man believes this will damage the world around us and must be fought. Neither man has any ability to objectively prove their belief. Neither man will let that lack of knowledge stand in the way of enforcing their views upon others. Both men indulge in unethical behavior that demonstrates yet another cost that pseudo-science imposes on modern society. (more…)
