Man produces greenhouse gases and greenhouse gases cause global warming, most scientists agree, but how, exactly, do greenhouse gases cause global warming? While theories abound, as do elaborate computer models incorporating a multitude of gases and other climatic factors, none has been conclusive. And if greenhouse gases aren't responsible, what else could be? A clear, verifiable mechanism showing how a greenhouse gas or other physical entity can drive climate change has eluded science. Until now.For more than a decade, Henrik Svensmark of the Danish National Space Center has been pursuing an explanation for why Earth cools and warms. His findings...

Most scientists who are labelled as "deniers" for their views on global warming don't embrace this role. They cringe at the thought of disagreeing with colleagues who think that the science is settled, they do their best to avoid making waves, and they fear being marginalized as cranks who disagree with the scientific consensus. Dr. Richard Lindzen is an exception.Dr. Lindzen is one of the original deniers -- among the first to criticize the scientific bureaucracy, and scientists themselves, for claims about global warming that he views as unfounded and alarmist. While he does not welcome the role he's acquired,...

A great melt is on in Antarctica. Its northern peninsula -- a jut of land extending to about 1,200 kilometres from Chile -- has seen a drastic increase in temperature, a thinning of ice sheets and, most alarmingly, a collapse of ice shelves. The Larsen A ice shelf, 1,600 square kilometres in size, fell off in 1995. The Wilkins ice shelf, 1,100 square kilometres, fell off in 1998 and the Larsen B, 13,500 square kilometres, dropped off in 2002. Meanwhile, the northern Antarctic Peninsula's temperatures have soared by six degrees celsius in the last 50 years.Antarctica represents the greatest threat...

You're a respected scientist, one of the best in your field. So respected, in fact, that when the United Nations decided to study the relationship between hurricanes and global warming for the largest scientific endeavour in its history -- its International Panel on Climate Change -- it called upon you and your expertise.You are Christopher Landsea of the Atlantic Oceanographic & Meteorological Laboratory. You were a contributing author for the UN's second International Panel on Climate Change in 1995, writing the sections on observed changes in tropical cyclones around the world. Then the IPCC called on you as a contributing...

One month ago, the world heard that global warming could lead to a global catastrophe "on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century." This assessment, from Sir Nicholas Stern, former chief economist of the World Bank, made banner headlines and led prominent leaders such as British Prime Minister Tony Blair to urge immediate action to stem global warming.It also led some prominent environmentalists to denounce Sir Nicholas for what they deemed an outrageous study bereft of credibility. None of the environmentalists issued a stronger...

In the global warming debate, there are essentially two broad camps. One believes that the science is settled, that global warming is serious and man-made, and that urgent action must be taken to mitigate or prevent a future calamity. The other believes that the science is far from settled, that precious little is known about global warming or its likely effects, and that prudence dictates more research and caution before intervening massively in the economy.The "science is settled" camp, much the larger of the two, includes many eminent scientists with impressive credentials. But just who are the global warming skeptics...

"I am afraid there are people who want to stop the economic growth, the rise in the standard of living (though not their own) and the ability of man to use the expanding wealth, science and technology for solving the actual pressing problems of mankind, especially of the developing countries." "I am also afraid that the same people, imprisoned in the Malthusian tenets and in their own megalomaniacal ambitions, want to regulate and constrain demographic development, which is something only the totalitarian regimes have until now dared to experiment with."

The final day of the 2008 International Conference on Climate Change, hosted by The Heartland Institute and more than 50 cosponsors, began with a keynote presentation by the Hon. Vaclav Klaus, president of the Czech Republic, who received a thunderous standing ovation from an international audience of some 500 scientists, economists, and other experts on global warming. It ended with withering criticism of the mainstream media's biased and alarmist coverage of the global warming issue by ABC News correspondent John Stossel. President Klaus--who won reelection just two weeks ago--explained his strong opposition to claims that global warming is a "crisis"...

Summary for Policymakers of the Report of the Nongovernmental International Panel on Climate ChangeWritten By: Edited by S. Fred Singer, Ph.D.Published In: Summary for PolicymakersPublication Date: March 2, 2008Publisher: Nongovernmental International Panel on Climate Change / The Heartland Insstitute Abstract:  The public’s fear of anthropogenic global warming seems to be at a fever pitch. Polls show most people in most countries believe human greenhouse gas emissions are a major cause of climate change and that action must be taken to reduce them, although most people apparently are not willing to make the financial sacrifices required.While the report of the...

The first full day of the 2008 International Conference on Climate Change, hosted by The Heartland Institute and more than 50 cosponsors, was by all accounts an extraordinary success, from the packed breakfast and lunch plenary sessions to the rapt attention given to panelists during the 20 concurrent sessions addressing nearly every aspect of paleoclimatology, climatology, and the economics and politics of climate change. It became clear this was no ordinary conference on climate change from the opening presentations by Dr. Robert Balling, professor of climatology at Arizona State University, and Dr. Ross McKitrick, associate professor of economics at the...

The 2008 International Conference on Climate Change, hosted by The Heartland Institute and more than 50 cosponsors, got off to a fast and successful start with a capacity crowd at the opening dinner, featuring opening remarks by Heartland President Joseph Bast, comedian Tim Slagle, and climatologist Patrick Michaels.Registration for the event exceeded 550, well beyond the 300-400 we hoped for. The room for the opening dinner was packed with guests from at least 11 countries, including Australia, Canada England, France, New Zealand, Poland, Puerto Rico, Russia, and Sweden. Hon. Vaclav Klaus, president of the Czech Republic, was a distinguished guest....

On May 18, NewsBusters introduced you to Kristen Byrnes, the fabulous fifteen-year-old from Maine who had torn apart many of the myths purported by the Global Warmingist-in-Chief, soon-to-be-Dr. Al Gore, in his schlockumentary “An Inconvenient Truth.”Now, the Precocious Ponderer from Portland is taking on the scientist that Gore relied on for much of his misinformation, James Hansen of NASA.In her recent report entitled “Houston, We Have a Problem,” Byrnes identified a serious concern with this so-called scientist that many anthropogenic global warming skeptics have been addressing for years (emphasis added throughout): James Hansen seems to have a busy life for someone...

Senior House Republicans are complaining about Democrats' plans to divert "scarce" intelligence funds to study global warming. The House next week will consider the Democrat-crafted Intelligence Authorization bill, which includes a provision directing an assessment of the effects that climate change has on national security. "Our job is to steal secrets," said Rep. Peter Hoekstra of Michigan, the ranking Republican on the Permanent Select Committee on Intelligence. "There are all kinds of people analyzing global warming, the Democrats even have a special committee on this," he told The Washington Times. "There's no value added by the intelligence community here; they...

What’s that about a consensus concerning anthropogenic global warming? Well, regardless of the assertions by such experts as Al Gore and Ellen Goodman, more and more professionals actually involved in the climate industry are speaking out against this man-made myth. The most recent announcement by skeptics came during a panel discussion Tuesday evening in Mayfield Heights, Ohio. Laufman, who has free-lanced for WOIO Channel 19 and taught meteorology courses at several local colleges, including Case Western Reserve University, also referenced history. "There was also a significant spike in world temperatures during the 1400s -- and that was well before the...

Some experts have questioned the alarmists theory on global warming leading to shrinkage of Himalayan glaciers. VK Raina, a leading glaciologist and former ADG of GSI is one among them. He feels that the research on Indian glaciers is negligible. Nothing but the remote sensing data forms the basis of these alarmists observations and not on the spot research. Raina told the Hindustan Times that out of 9,575 glaciers in India, till date, research has been conducted only on about 50. Nearly 200 years data has shown that nothing abnormal has occurred in any of these glaciers. It is simple....

In new ads, ski company says global warming could dry up snow during the next century... The Aspen Skiing Co. hopes potential customers are ready for a snow job. On Wednesday, the company unveiled a new advertising campaign for the 2006-07 season that centers around the message that snow — and skiing — will disappear around 2100 if humans don’t take drastic action to slow global warming. Three full-page ads, which show a melting snowflake imposed over Highland Bowl, will run in SKI and Outside magazines in the next few months. One ad portrays a “certificate of death” for snow....

Sept. 21, 2006 — The average temperature of the water near the top of the Earth's oceans has cooled significantly since 2003. The new research suggests that global warming trends are not always steady in their effects on ocean temperatures. [SNIP]Lyman said the recent cooling is not unprecedented. "While global ocean temperatures have generally increased over the past 50 years, there have also been substantial decadal decreases," he said. "Other studies have shown that a similar rapid cooling took place from 1980 to 1983. But overall, the long-term trend is warming."[SNIP]Lyman said the cause of the recent cooling is not...

Where are the Hurricanes? I blame global warming...http://www.deanesmay.com/posts/1155133659.shtml Scott Kirwin Aug 9, 2006 Nearly a year ago the country was being slammed by hurricanes. As Americans suffered some claimed that the ferocity of Katrina and Rita was due to global warming. A search of Dean's World shows that this site is one of the few that argued against that idea over the course of 2005. So here we are, a year later. Where are the hurricanes? Where is the fury of Mother Nature? Where are her righteous swirls of rain and wind that shall smite the evil non-Kyoto Protocol signing...

... I sat in a roomful of journalists 10 years ago while Stanford climatologist Stephen Schneider lectured us on a big problem in our profession: soliciting opposing points of view. In the debate over climate change, Schneider said, there simply was no legitimate opposing view to the scientific consensus that man - made carbon emissions drive global warming. To suggest or report otherwise, he said, was irresponsible. Indeed. I attended a week's worth of lectures on global warming at the Chautauqua Institution last month. Al Gore delivered the kickoff lecture, and, 10 years later, he reiterated Schneider's directive. There is...

An expert with the U.S. National Oceanic and Atmospheric Administration (NOAA) is questioning the connection between climate change and the appearance of more intense hurricanes in recent years. Historical data on hurricanes is too crude to determine long-term trends in intensity, says Christopher Landsea, a science and operations officer with NOAA's National Hurricane Center in Miami, Florida. Extreme hurricanes like Katrina were likely as common around the world 30 years ago as they are today, Landsea says. But since satellite imagery was poorer, storm intensities were underreported. Landsea is the lead author of a commentary in today's issue of the...
