A roughly linear global temperature increase of about 0.5°C per 100 years seems to have occurred from about 1800, or even much earlier, to the present. This value may be compared with what the International Panel on Climate Change (IPCC) scientists consider to be the manmade greenhouse effect of 0.6°C per 100 years. This long-lasting linear warming trend is likely to be a natural change.
An Inconvenient Truth, Al Gore's documentary on the threat posed by global warming, took home two Oscars at the recently held 79th annual Academy Awards. The Academy awarded the filmmakers with the Oscar for best documentary and gave another to singer and songwriter Melissa Etheridge for the song "I Need to Wake Up" that was used in the film.
On March 2-4, more than 100 scientists, many of considerable renown, attended a conference in New York, sponsored by the Heartland Institute, called the 2008 International Conference on Climate Change. Also in attendance were over 300 other delegates, including Vaclav Klaus, president of the Czech Republic.
The past couple of years have seen many prominent scientists, including former leading global-warming alarmists, converting to the climate “skeptic” or “realist” camp. However, most Americans are unaware of these defections, since the major media censor these stories, while continuing to hype unfounded predictions of impending climate catastrophe.
The high price of oil has caused those responsible for energy generation to think increasingly about coal as a fuel source, mainly because our nation’s coal reserves are much more abundant than our supplies of petroleum. However, fears of the byproducts of burning coal, most notably the emission of carbon dioxide into the atmosphere, have many people worried.
James Hansen, an atmospheric scientist and the director of NASA’s Goddard Institute for Space Studies, has long been the most prominent scientific advocate of the catastrophic global-warming theory. However, on June 23, Dr. Hansen took an unprecedented step to turn up the volume on his message: speaking before the House Select Committee for Energy Independence and Climate Change, he called for the chief executives of large fossil-fuel companies to be put on trial for “high crimes against humanity and nature,” accusing them of actively spreading doubt about global warming in the same way that tobacco companies allegedly tried to hide the connection between smoking and cancer.
Secretary of the Interior Dirk Kempthorne announced at a May 14 press conference that he is accepting the recommendation of U.S. Fish and Wildlife Service Director Dale Hall to list the polar bear as a threatened species under the Endangered Species Act.
