POLAR BEARS THRIVING

"Global warming could cause polar bears to go extinct by the end of the century by eroding the sea ice that sustains them," is the dire warning contained in a new report from an international group of "researchers" called the Arctic Climate Impact Assessment. I'm not quite sure what the future holds for polar bears, but it doesn't appear that any alleged manmade global warming has anything to do with it.

The report, entitled "Impacts of a Warming Arctic," pretty much debunks itself on page 23 in the graph labeled, "Observed Arctic Temperature, 1900 to Present. The graph shows that Arctic temperatures fluctuate naturally in regular cycles that are roughly 40 years long. The Arctic seems currently to be undergoing a warming phase - similar to one experienced between 1920-1950 - which will likely be followed by a cooling phase - similar to the one experienced between 1950-1990.

The report's claim that increased manmade emissions of greenhouse gases are causing Arctic temperatures to rise is debunked by the same graph, which indicates that the near surface Arctic air temperature was higher around 1940 than now, despite all the greenhouse gas emissions since that time.

Also self-debunking is the report's statement, "Since the start of the industrial revolution, the atmospheric carbon dioxide concentration has increased by about 35 percent and the global average temperature has risen by about 0.6 degrees Centigrade." So despite all the greenhouse gases emitted by human activity over a period of 200 years - we're supposed to worry, and even panic, about a measly 0.6 degree Centrigrade rise in average global temperature during that time? Even if such a slight temperature change could credibly be estimated, it would seem to be well within the natural variation in average global temperature, which in the case of the Arctic, for example, is a range of about 3 degrees Centigrade. Remember, global climate isn't static - it's always either cooling or warming.

Even though manmade greenhouse gas emissions and warmer temperatures don't seem to be a problem in the Arctic according to their own data, the researchers nevertheless blamed them for causing supposed 15 percent declines in both the average weight of adult polar bears and number of cubs born between 1981 and 1998 in the Hudson Bay region.

The 1999 study in the science journal Arctic that first reported apparent problems among the Hudson Bay polar bear population suggested that their condition may be related to the earlier seasonal break-up of sea ice on western Hudson Bay -a phenomenon that seems to correlate with the 1950-1990 Arctic warm-up. But, as mention previously, the 1950-1990 Arctic warming period seems to be part of a natural cycle and not due to manmade emissions of greenhouse gases.

Moreover, the notion of a declining polar bear population doesn't square well available information. A Canadian Press Newswire story earlier this year reported that, in three Arctic villages, polar bears "are so abundant there's a public safety issue." The local polar bear population reportedly increased from about 2,100 in 1997 to as many as 2,600 in 2004. Inuit hunters wanted to be able to kill more bears because they are "fearsome predators." An aerial survey of Alaskan polar bears published in "Arctic" (December 2003) reported a greater polar bear density than previous survey estimates dating back to 1987.

DOTTY CALIFORNIA EMISSION REGULATIONS FOR CARS

"On September 24, California's Air Resources Board (CARB) adopted a plan to regulate greenhouse gas (GHG) emissions from new cars and trucks starting in 2009. To sell cars in California, automakers will have to reduce fleet average GHG emissions by 22 percent in 2012 and 30 percent in 2016. CARB's rulemaking is a raw deal for auto dealers in California and any other state that mimics California's plan. To justify its rule, CARB cites the U.N. Intergovernmental Panel on Climate Change's (IPCC) scary forecast of a 2.5øF to 10.4øF warming over the next 100 years. However, the IPCC forecast is junk science. The IPCC's warming estimates presuppose ridiculous economic growth rates in developing countries (i.e., most of the world). For example, even the IPCC's low-end (2.5øF) forecast assumes that underachievers like North Korea, Libya, and Argentina grow so rapidly their per capita incomes will surpass U.S. per capita income in 2100! CARB's rule has no credible scientific rationale.

Sierra Research, Inc., in a report written for the Alliance of Automobile Manufacturers, finds multiple problems in CARB's cost-effectiveness calculation. CARB inflated vehicle costs in the 2009 baseline (no regulation) case by assuming general adoption of expensive technologies such as 5- and 6-speed automatic transmissions. CARB knocked down by 30 percent its own contract researcher's cost estimates based on nothing more specific than staff's "experience" and the potential for "unforeseen innovations." CARB assumed that consumers benefit from fuel savings years after most cars are sold or scrapped. Whereas CARB projects a net lifetime consumer saving of $1,703, Sierra estimates a net loss of $3,357. The rule will reduce vehicle sales and put the brakes on the chief source of air quality improvement-replacement of older vehicles with newer, cleaner models. CARB's rule is bad for the environment!

If implemented, CARB's plan will hammer California auto dealers. The rule applies to automakers, not auto owners or operators. Unless CARB is prepared to build a wall around California, it cannot stop people from importing less regulated, more affordable cars from out of state.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
