POLAR BEARS MAY BE LIKE THE CANARY IN THE COAL MINE.

THIS MAY PROVE TO BE THE GREATEST EMERGENCY SINCE THE ATTACK ON PEARL HARBOR!

See: Life Threatening Danger at http://www.aesopinstitute.org updated today.

Also, What to Do! on the same website.

Chris Landau, a geologist, believes the solution may be to drill 8 or more new, vertical wells, in a circle around the gusher, on the assumption that far more oil will be produced than can otherwise be controlled.

He states the oil might continue to be produced in huge quantities.

He believes several new wells can allow recovery of the oil, which may need to continue for a very, very, long time.

You may want to also read Moving Beyond Oil and Running on Water on that Aesop site.

With adequate support, a 24/7 development program could move breakthrough technologies into production.

This may prove to be an emergency equivalent to nuclear war!

These new technologies are much less complicated than weapons systems.

The science is hard to believe, as it disagrees with conventional wisdom. But, independent and National laboratories are increasingly involved. Once prototypes for schools are in production, it will become obvious that gasoline, oil, coal, natural gas and nuclear power will face low cost competition that can leave all of them behind.

Recognize this emergency! We have a difficult, but possible, job to do!

So, let's begin to really do it! An important step is to learn more about what to do!

Great comments on this issue, Stefan Zeiss! The Climategate scandals revealed just how corrupt the Climate Change "scientific community" had become and proved that with billions of dollars in research money and lucrative "green" businesses at stake, scientists at the highest level of the debate chose politics over science. They had an opportunity at that point to regain their credibility by returning to hard science and purging their ranks of unscrupulous left-wing puppets, but they blew it. They just pretended like the Climategate scandals never happened and returned to the same tired approach that got them into trouble in the first place: adopt the robotic mantra that "the science is settled" and that the "debate is over"; aggressively denounce scientists expressing a contrary viewpoint as "quacks" and destroy their credibility in the scientific community (this includes bullying the editors of scientific periodicals that might consider publishing a "denier's" findings); arrogantly and viciously ridicule non-scientist "deniers" as slack-jawed imbeciles who are simply too stupid and uneducated to understand the overwhelming scientific evidence that conclusively proves the existence of AGW.

So, they are still using the same tactics only now it's pathetic instead of menacing. No one is afraid of them anymore.

Fanned.

Projections of future climate change anticipate an additional warming of 2.0 to 11.5 F (1.1 to 6.4 C) over the 21st century, on top of the 1.4 oF already observed over the past 100 years...

There is also the potential that the Earth system could cross thresholds that result in abrupt changes or other "surprises." The potential consequences of such events could be irreversible and highly challenging, but their likelihood is not very well understood.

Despite these uncertainties and complexities, it is clear that Earth's future climate will be unlike the climate that ecosystems and human societies have become accustomed to during the last 10,000 years, leading to significant challenges across a broad range of human endeavors. It is likewise reasonable to expect that the magnitude of future climate change and the severity of its impacts will be larger if actions are not taken to limit its magnitude and adapt to its impacts.

Speaking of tipping points...

As Newsweek put it recently,

"Some of the IPCC’s most-quoted data and recommendations were taken straight out of unchecked activist brochures, newspaper articles, and corporate reports—including claims of plummeting crop yields in Africa and the rising costs of warming-related natural disasters, both of which have been refuted by academic studies."

From the Newsweek article, which is just a blog of a couple paragraphs.

"Very few scientists dispute a link between man-made CO2 and global warming."

http://www.newsweek.com/2010/05/28/uncertain-science.html

By the way, the costs of natural disasters are rising. There is also more development along coastal areas, which makes the comparison's difficult. Roger Piekle Jr. has made a whole career out of stating that exact same thing in different ways.

The Royal Society has appointed a panel to rewrite the 350-year-old institution’s official position on global warming. It will publish a new “guide to the science of climate change” this summer. The society has been accused by 43 of its Fellows of refusing to accept dissenting views on climate change and exaggerating the degree of certainty that man-made emissions are the main cause.

The society appears to have conceded that it needs to correct previous statements. It said: “Any public perception that science is somehow fully settled is wholly incorrect — there is always room for new observations, theories, measurements.” This contradicts a comment by the society’s previous president, Lord May, who was once quoted as saying: “The debate on climate change is over.”

"Record temperatures in northern India have claimed hundreds of lives in what is believed to be the hottest summer in the country since records began in the late 1800s."

"The death toll is expected to rise with experts forecasting temperatures approaching 50C (122F) in coming weeks. More than 100 people are reported to have died in the state of Gujarat where the mercury topped at 48.5C last week. At least 90 died in Maharashtra, 35 in Rajasthan and 34 in Bihar."

"Human-caused global warming is poised to wipe out polar bears. The normally staid U.S. Geological Survey -- studying whether the bear should be listed as a threatened species under the Endangered Species Act -- concluded grimly last Friday:"

"Projected changes in future sea ice conditions, if realized, will result in loss of approximately 2/3 of the world's current polar bear population by the mid 21st century. Because the observed trajectory of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative."

"That's right -- this grim prediction is optimistic, a best-case scenario."

* BP, the largest oil company in the UK and one of the largest in the world, has this opinion:

"There is an increasing consensus that climate change is linked to the consumption of carbon based fuels and that action is required now to avoid further increases in carbon emissions as the global demand for energy increases."

* Shell Oil (yes, as in oil, the fossil fuel) says:

Shell shares the widespread concern that the emission of greenhouse gases from human activities is leading to changes in the global climate.

* Eighteen CEOs of Canada's largest corporations had this to say in an open letter to the Prime Minister of Canada:

"Our organizations accept that a strong response is required to the strengthening evidence in the scientific assessments of the Intergovernmental Panel on Climate Change (IPCC). We accept the IPCC consensus that climate change raises the risk of severe consequences for human health and security and the environment. We note that Canada is particularly vulnerable to the impacts of climate change."

"Scientists on the committee have argued that although Canada's polar bear population has improved over the last 50 years, the future of the species could be threatened by climate change and receding sea ice."

"Certainly, we recognize that the Arctic may experience substantial impacts from climate change," Shewchuk said. "But listing polar bears now, based on predicted but unknown future impacts, is not reasonable."

Are polar bears endangered?

"Experts in polar bear science believe they are. They predict that as the Arctic continues to warm due to climate change, two-thirds of the world's polar bears could disappear by 2030."

"In 2005, PBSG classified polar bears as vulnerable on the IUCN World Conservation Union's Red List of Threatened Species" noting that extinction could occur due to sea ice changes."

"In May 2008, U.S. Department of the Interior listed the polar bear as a Threatened Species under the Endangered Species Act. Russia lists the polar bear as "a species of concern."

"At the 2009 meeting of the IUCN Polar Bear Specialist Group (PBSG), the world's leading polar bear scientists reported that of the 19 subpopulations of polar bears, eight were declining, three were stable, and one was increasing. They lacked sufficient data to say what is happening to the remaining seven."

Richard2: "From Newsweek magazine..."

Meanwhile, back in the world of actual science...

The U.S. National Academy of Sciences, 2010:

--------------------------------------------
There is a strong, credible body of evidence, based on multiple lines of research, documenting that Earth is warming. Strong evidence also indicates that recent warming is largely caused by human activities, especially the release of greenhouse gases through the burning of fossil fuels. Global warming is closely associated with other climate changes and impacts, including rising sea levels, increases in intense rainfall events, decreases in snow cover and sea ice, more frequent and intense heat waves, increases in wildfires, longer growing seasons, and ocean acidification. Individually and collectively, these changes pose risks for a wide range of human and environmental systems. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations...

As said by the US Global Change Resource Program...

1. Global warming is unequivocal and primarily human-induced.
Global temperature has increased over the past 50 years. This observed increase is due primarily to human-induced emissions of heat-trapping gases. (p. 13)

2. Climate changes are underway in the United States and are projected to grow.
Climate-related changes are already observed in the United States and its coastal waters. These include increases in heavy downpours, rising temperature and sea level, rapidly retreating glaciers, thawing permafrost, lengthening growing seasons, lengthening ice-free seasons in the ocean and on lakes and rivers, earlier snowmelt, and alterations in river flows. These changes are projected to grow. (p. 27)

3. Widespread climate-related impacts are occurring now and are expected to increase.
Climate changes are already affecting water, energy, transportation, agriculture, ecosystems, and health. These impacts are different from region to region and will grow under projected climate change. (p. 41-106, 107-152)

From Newsweek magazine: The lead paragraph of a longer article:

"UNCERTAIN SCIENCE

Bickering and defensive, climate researchers have lost the public’s trust.
Blame economic worries, another freezing winter, or the cascade of scandals emerging from the world’s leading climate-research body, the Intergovernmental Panel on Climate Change (IPCC). But concern over global warming has cooled down dramatically. In über-green Germany, only 42 percent of citizens worry about global warming now, down from 62 percent in 2006. In Britain, just 26 percent believe climate change is man-made, down from 41 percent as recently as November 2009. And Americans rank global warming dead last in a list of 21 problems that concern them, according to a January Pew poll."

We told you guys that a freezing winter is a weather phenomena and does not alter climate science, which is not altered by opinion polls either.

According to NASA, "2009 was tied for the second warmest year in the modern record, a new NASA analysis of global surface temperature shows. The analysis, conducted by the Goddard Institute for Space Studies (GISS) in New York City, also shows that in the Southern Hemisphere, 2009 was the warmest year since modern records began in 1880."

People not versed in the science of global warming are less concerned about it because they're more concerned about being able to feed themselves and their families.

Meanwhile, the Pentagon and the CIA are more concerned about how MMGW is going to adversely affect global economic and political stability.
