JENSEN BEACH, Fla. – Al Gore’s film about purported global warming, “An Inconvenient Truth,” is not only favored to win an Oscar this weekend for best documentary feature, it is also prompting at least one couple in this South Florida town to change its retirement plans.

David and Lani Havens had dreamed of spending their golden years sailing their boat, painting and relaxing. But ever since seeing the movie alleging severe climate change, the pair has dropped anchor to become environmental activists.

“We’re selling our boat. This is too important,” David Havens, 71, told the Stuart News. “We found there’s too much to do.”

The Havenses purchased seven copies of Gore’s film, and created packets to promote discussions and letter-writing campaigns to stop what they believe is a warming trend for the planet.

“With the (Bush) administration pushing it doesn’t exist, people are very confused,” David Havens, an ordained minister, said. “It’s an ethical issue, and the churches should be a leader. It’s how we take care of the Earth and whether humans can live on it.”

As WND reported last September, a leading U.S. climate researcher claimed there’s a decade at most left to address global warming before environmental disaster takes place, but the federal government issued a report showing the year 1936 had a hotter summer than 2006.

“The average June-August 2006 temperature for the contiguous United States (based on preliminary data) was 2.4 degrees F (1.3 degrees C) above the 20th century average of 72.1 degrees F (22.3 degrees C),” said the NOAA report. “This was the second warmest summer on record, slightly cooler than the record of 74.7 degrees F set in 1936 during the Dust Bowl era. This summer’s average was 74.5 degrees F. Eight of the past ten summers have been warmer than the U.S. average for the same period.”

U.S. states experienced 2nd-hottest summer on record in 2006, with NOAA ranking them according to where they stand in the 112 years of record-keeping. 112 is the warmest and 1 is the coldest

Despite recent claims regarding climate change, the idea the Earth is heating up is hardly a universal belief.

As WND previously reported, a NASA-funded study noted some climate forecasts might be exaggerating estimations of global warming.

The space agency said climate models possibly were overestimating the amount of water vapor entering the atmosphere as the Earth warms.

The theory many scientists work with says the Earth heats up in response to human emissions of greenhouse gases such as carbon dioxide, causing more water to evaporate from the ocean into the atmosphere.

WND also reported that Dr. Fred Singer, professor emeritus of environmental sciences at the University of Virginia, maintains there has been little or no warming since about 1940.

“Any warming from the growth of greenhouse gases is likely to be minor, difficult to detect above the natural fluctuations of the climate, and therefore inconsequential,” Singer wrote in a climate-change essay. “In addition, the impacts of warming and of higher CO2 levels are likely to be beneficial for human activities and especially for agriculture.”

In July 2004, the London Telegraph reported on a study by Swiss and German scientists suggesting increased radiation from the sun – not human activity – was to blame for climate changes.

“The sun is in a changed state,” said Dr. Sami Solanki of the Max Planck Institute for Solar System Research in Gottingen, Germany. “It is brighter than it was a few hundred years ago and this brightening started relatively recently – in the last 100 to 150 years.”

The research adds credence to the beliefs of British professor David Bellamy, president of the London-based Conservation Foundation.

“Global warming – at least the modern nightmare version – is a myth,” Bellamy told the Telegraph. “I am sure of it and so are a growing number of scientists. But what is really worrying is that the world’s politicians and policy-makers are not.

“Instead, they have an unshakeable faith in what has, unfortunately, become one of the central credos of the environmental movement: humans burn fossil fuels, which release increased levels of carbon dioxide – the principal so-called greenhouse gas – into the atmosphere, causing the atmosphere to heat up. They say this is global warming, I say this is poppycock.”

Another study teaming scientists at the Planck Institute with others in the U.S. and Switzerland claimed the energy from the sun has varied only slightly in the past 1,000 years, suggesting human factors were to blame for any increase in temperatures on Earth.

“Overall, we can find no evidence for solar luminosity variations of sufficient amplitude to drive significant climate variations on centennial, millennial or even million-year timescales,” the report said.

“Our results imply that over the past century climate change due to human influences must far outweigh the effects of changes in the sun’s brightness,” said Tom Wigley of the U.S. National Center for Atmospheric Research.

In December 2003, NASA reported global warming on Mars, even though the red planet is not subject to pollutants of human habitation.

“One explanation could be that Mars is just coming out of an ice age,” William Feldman of the Los Alamos National Laboratory told

In July 2004, WND reported on a controversial study released by the Congressional Black Caucus Foundation suggesting white people were most to blame for global warming.

The study alleged responsibility for the problem does not lie primarily with blacks, stating, “African-American households emit 20 percent less carbon dioxide than white households. Historically, this difference was even higher.”
