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.
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.
According to former Vice President Al Gore, “the science is settled” on climate change. “The planet has a fever,” Gore said during testimony before Congress in 2007, and its cause, he averred, is too many cars, power plants, factories, and other human-related sources putting too many emissions into the atmosphere.
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.
Hardly a stump speech goes by without a political candidate calling for “more renewable sources of energy such as wind or solar” to either stop our dependence on foreign oil or to slow the CO2 emissions that mean certain doom for our planet. The politicians are doing what most politicians do: spewing rhetoric that they know voters want to hear; proposing programs they know little or nothing about.
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.
