New, convincing evidence indicates global warming is caused by cosmic rays and the sun — not humans

The science is now all-but-settled on global warming, convincing new evidence demonstrates, but Al Gore, the IPCC and other global warming doomsayers won’t be celebrating. The new findings point to cosmic rays and the sun — not human activities — as the dominant controller of climate on Earth.

The research, published with little fanfare this week in the prestigious journal Nature, comes from über-prestigious CERN, the European Organization for Nuclear Research, one of the world’s largest centres for scientific research involving 60 countries and 8,000 scientists at more than 600 universities and national laboratories. CERN is the organization that invented the Read more…

This image was created with data acquired by the Atmospheric Infrared Sounder, AIRS, during July 2008. The image shows large scale patterns of carbon dioxide concentrations that are transported around the Earth by the general circulation of the atmosphere

 

In contrast to the increased growth in plants that scientists have often seen in studies with elevated CO2, the first synthesis paper on the comprehensive CLIMAITE project shows that the combination of summer drought and potential plant growth-promoting factors such as higher temperatures and increased CO2 together limit the effect of CO2 increased plant growth significantly.

“When you’ve previously seen a significantly higher plant growth at elevated CO2 concentrations, it is typically because it has been controlled studies, where only the was changed. We fundamentally had the theory that you have to look at the combination of the different variables, since the plants in the future will be exposed to multiple changes simultaneously, “explains Klaus Steenberg Larsen, who is a researcher in the Biosystems Division at Risø DTU and lead author on the scientific paper.

An international team of researchers has confirmed the presence of a deep-reaching ocean circulation system off Iceland that could have “important ramifications” for ocean circulation’s impact on climate in the Northern Hemisphere.

The current, called the North Icelandic Jet (NIJ), contributes to a key component of the Atlantic Meridional Overturning Circulation (AMOC), also known as the “great ocean conveyor belt,” which is critically important for regulating Earth’s climate.

Climate specialists have been concerned that the conveyor belt is Read more…

New NASA Data Blow Gaping Hole In Global Warming Alarmism

NASA satellite data from the years 2000 through 2011 show the Earth’s atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.

Study co-author Dr. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville and U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite, reports that real-world data from NASA’s Terra satellite contradict Read more…

U.S. West Coast Erosion Spiked In Winter 2009-10, Previewing Likely Future As Climate Changes

Knowing that the U.S. West Coast was battered during the winter before last by a climatic pattern expected more often in the future, scientists have now pieced together a San Diego-to-Seattle assessment of the damage wrought by that winter’s extreme waves and higher-than-usual water levels. Getting a better understanding of how the 2009–10 conditions tore away and reshaped shorelines will help coastal experts better predict future changes that may be in store for the Pacific coast, the researchers say.

Loss of top animal predators has massive ecological effects

“Trophic Downgrading of Planet Earth,” a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth’s terrestrial, freshwater, and marine ecosystems.

The paper claims that the loss of apex consumers from ecosystems “may be humankind’s most pervasive influence on nature.” The research was funded primarily by the Institute for Ocean Conservation Science at Stony Brook University with support from The Pew Charitable Trusts.

The paper is co-authored by the Institute’s executive director, Dr. Ellen K. Pikitch, and the lead author is Dr. James A. Estes, professor of ecology and evolution at the University of California at Santa Cruz.

The review, conducted by an international team of 24 scientists, illuminates the Read more…

Powers That Be preparing for lockdown as Earth Changes increase? UN security council to consider ‘climate change peacekeeping force’

Special meeting to discuss ‘green helmets’ force to intervene in conflicts caused by rising seas levels and shrinking resources

A special meeting of the United Nations security council is due to consider whether to expand its mission to keep the peace in an era of climate change.

Small island states, which could disappear beneath rising seas, are pushing the security council to intervene to combat the threat to their existence.

There has been talk, meanwhile, of a new environmental peacekeeping force – green helmets – which could step into conflicts caused by shrinking resources.

The UN secretary general, Ban Ki-Moon, is expected to address the meeting on Wednesday.

But Germany, which called the meeting, has warned it is premature to expect the council to take the plunge into green peacemaking or even adopt climate change as one of its key areas of concern.

“It is too early to seriously think about council action on climate change. This is clearly not Read more…

CERN ‘gags’ physicists about role of cosmic rays in climate change

July 20, 2011 – DENMARK – The chief of the world’s leading physics lab at CERN in Geneva has prohibited scientists from drawing conclusions from a major experiment. The CLOUD (“Cosmics Leaving Outdoor Droplets”) experiment examines the role that energetic particles from deep space play in cloud formation. CLOUD uses CERN’s proton synchrotron to examine nucleation. CERN Director General Rolf-Dieter Heuer told Welt Online that the scientists should refrain from drawing conclusions from the latest experiment. “I have asked the colleagues to present the results clearly, but not to Read more…

Farm Animal Disease to Increase With Climate Change, Scientists Say

sciencedaily

Researchers looked at changes in the behaviour of bluetongue — a viral disease of cattle and sheep — from the 1960s to the present day, as well as what could happen to the transmission of the virus 40 years into the future. They found, for the first time, that an outbreak of a disease could be explained by changes to the climate.

In Europe, more than 80,000 outbreaks of bluetongue were reported to the World Animal Health Organisation between 1998 and 2010, and millions of animals died as a result of the disease. Bluetongue was previously restricted to Africa and Asia, but its emergence in Europe is thought to be linked to increased temperatures, which allows the insects that carry the virus to spread to new regions and transmit the virus more effectively.

Researchers produced a mathematical model that explains how Read more…
