Impact of global warming on weather patterns underestimated

September 22, 2005
The impact of global warming on European weather patterns has been underestimated, according to a new report published in Nature this week.

Dr Gillett, of the University of East Anglia's Climatic Research Unit, compared Northern Hemisphere air pressure changes at sea level over the past 50 years with predicted changes from nine state-of-the-art climate models.

The Northern Hemisphere Circulation study found that present climate change models - computer representations of the atmosphere, ocean and land surface-have underestimated the changes in air pressure, leading to an underestimate of the impact of global warming on weather patterns.

While observations reveal that air pressure has dropped 4 millibars over Iceland in the past 50 years and risen by up to 3 millibars in the sub tropics, climate model trends were less than 1 millibar.

Previous research has shown that over the past thirty years air pressure trends have contributed about 1°C to warming over the UK in winter and up to 3°C in Siberia, as well as 60% of the rainfall increase seen in Scotland. Over Southern England, the air pressure trends have likely made the winters milder and windier. Dr Gillett's findings indicate that these changes are not well-captured by climate models.

Dr Gillett, said: "Climate models are very good at simulating temperature changes, but this study shows that their simulations of pressure trends in the northern Hemisphere are not realistic. If we could understand and correct this bias, predictions of future regional climate change would be improved."

This Changes Everything: Capitalism vs. The Climate

This Changes Everything: Capitalism vs. The Climate
by Naomi Klein (Author)


The most important book yet from the author of the international bestseller The Shock Doctrine, a brilliant explanation of why the climate crisis challenges us to abandon the core “free market” ideology of our time, restructure the global economy, and remake our political systems.

In short, either we embrace radical change ourselves or radical changes will be visited upon our physical world. The status quo is no longer an option.

In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance...

The Great Global Warming Blunder: How Mother Nature Fooled the Worldâs Top Climate Scientists

The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists
by Roy W Spencer (Author)


The Great Global Warming Blunder unveils new evidence from major scientific findings that explode the conventional wisdom on climate change and reshape the global warming debate as we know it. Roy W. Spencer, a former senior NASA climatologist, reveals how climate researchers have mistaken cause and effect when analyzing cloud behavior and have been duped by Mother Nature into believing the Earth’s climate system is far more sensitive to human activities and carbon dioxide than it really is.

In fact, Spencer presents astonishing new evidence that recent warming is not the fault of humans, but the result of chaotic, internal natural cycles that have been causing periods of warming and cooling for millennia. More carbon dioxide in the atmosphere is not necessarily to be feared; The...

Climategate: A Veteran Meteorologist Exposes the Global Warming Scam
by Brian Sussman (Author)


Those now notorious intercepted emails documenting leading scientists conspiring to squelch global-warming skeptics and falsifying data proved exactly what Brian Sussman has been saying for years. Climategate is intended for anyone who has ever expressed skepticism about the clamorous environmentalist claims that the Earth is in peril because of mankind's appetite for carbon-based fuels. By tracing the origins of the current climate scare, Sussman guides the reader from the diabolical minds of Marx and Engles in the 1800s, to the global governance machinations of the United Nations today. Climategate is a call to action, warning Americans that their future is being undermined by a phony pseudo-science aimed at altering and dominating every aspect of life in the United States and the...

Climate Cover-Up: The Crusade to Deny Global Warming
by James Hoggan (Author), Richard Littlemore (Contributor)


Talk of global warming is nearly inescapable these days — but there are some who believe the concept of climate change is an elaborate hoax. Despite the input of the world’s leading climate scientists, the urgings of politicians, and the outcry of many grassroots activists, many Americans continue to ignore the warning signs of severe climate shifts. How did this happen? Climate Cover-up seeks to answer this question, describing the pollsters and public faces who have crafted careful language to refute the findings of environmental scientists. Exploring the PR techniques, phony "think tanks," and funding used to pervert scientific fact, this book serves as a wake-up call to those who still wish to deny the inconvenient truth.

Windfall: The Booming Business of Global Warming
by Mckenzie Funk (Author)


A fascinating investigation into how people around the globe are cashing in on a warming world

McKenzie Funk has spent the last six years reporting around the world on how we are preparing for a warmer planet. Funk shows us that the best way to understand the catastrophe of global warming is to see it through the eyes of those who see it most clearly—as a market opportunity.

Global warming’s physical impacts can be separated into three broad categories: melt, drought, and deluge. Funk travels to two dozen countries to profile entrepreneurial people who see in each of these forces a potential windfall.

The melt is a boon for newly arable, mineral-rich regions of the Arctic, such as Greenland—and for the surprising kings of the manmade snow trade, the Israelis....
