Giant pipe and balloon to pump water into the sky in climate experiment
Field test by British academics marks first step towards recreating an artificial volcano that would inject particles into the stratosphere and cool the planet
It sounds barmy, audacious or sci-fi: a tethered balloon the size of Wembley stadium suspended 20km above Earth, linked to the ground by a giant garden hose pumping hundreds of tonnes of minute chemical particles a day into the thin stratospheric air to reflect sunlight and cool the planet.
Cosmic Radiation, Clouds, & Global Warming
Rumor is that James Hansen was so upset by CERN’s CLOUD experiment results that he and a gaggle of rabid environmentalists stormed the White House and demanded that cosmic rays be outlawed. Or something: it is always difficult to say what is on the collective mind of a mob.
Anyway, Hansen was shuttled off to the cooler and hasn’t been heard from since. And as of this morning, there is still no word from the White House on how cosmic rays could be blamed on George Bush. (William M. Briggs)
Nir Shaviv: The CLOUD is clearing

The CLOUD collaboration from CERN finally had their results published in Nature (TRF, full PDF), showing that ionization increases the nucleation rate of condensation nuclei. The results are very beautiful and they demonstrate, yet again, how cosmic rays (which govern the amount of atmospheric ionization) can in principle have an effect on climate. (TRF)
CLOUD And The Cosmic Ray Climate Change Blow Up

It is simply science at work – finally, after a decade and a half of circling the wagons, hypotheses that were dismissed as conspiratorial nonsense by zealots get a chance to live or die by the scientific method and not by aggressive posturing. (GWPF)
Extreme 2010 Russian fires and Pakistan floods linked meteorologically
GREENBELT, Md. — Two of the most destructive natural disasters of 2010 were closely linked by a single meteorological event, even though they occurred 1,500 miles (2,414 km) apart and were of completely different natures, a new NASA study suggests.
The research finds that the same large-scale meteorological event — an abnormal Rossby wave — sparked extreme heat and persistent wildfires in Russia as well as unusual downstream wind patterns that shifted rainfall in the Indian monsoon region and fueled heavy flooding in Pakistan. Although the heat wave started before the floods, both events attained maximum strength at approximately the same time, the researchers found by analyzing satellite data generated by NASA instruments capable of measuring the land surface temperature, precipitation intensity and wildfire activity.
William Lau and Kyu-Myong Kim, atmospheric scientists at NASA’s Goddard Space Flight Center in Greenbelt, Md., authored the study, which the Journal of Hydrometeorology published in August.
A Rossby Connection
The atmosphere, gaseous and transparent, may not seem like a fluid, but that’s precisely how the thin layer of air encasing the planet behaves. As Earth spins on its axis, huge rivers of air — scientists call them Rossby waves — meander around the globe in a westerly direction. Currents in the center of these waves form the jet streams, fast-moving columns of air that push weather systems from west to east. (EurekAlert)
Sweden’s Sea Ice Worries Lead To Icebreaker Recall
Wednesday, 31 August 2011 19:34 Autonomous Mind
One problem with ‘global warming’ that scientists and journalists seem to gloss over is that it doesn’t seem to be, well, global. Some areas have exhibited more warming than others.
The Arctic is one area that gets a lot of focus. Each summer the media makes a big deal of the extent of Arctic sea ice melt during the warmest months of the year, focusing on navigation passages and often proclaiming that before long the summer will see all the Arctic ice melt away. The BBC never misses an opportunity to relay the story, even if it is barely mentioned elsewhere, and rolled out the latest iteration of it last week.
However there seems to be a lack of coverage about the increasing extent of sea ice in the winter. With the non stop global warming narrative burned onto the subconscious of decision makers, it the therefore of little surprise that there has been barely any investment in new maritime icebreaking capability.

Coldest summer in 20 years or so
I’ve noticed that many Americans – members of the nation that dominates TRF visits – tend to extrapolate the events in the U.S. to the whole globe. And because the U.S. has seen a pretty warm weather, many people think that the Northern Hemisphere has experienced a warm summer.
Well, it’s not the case. (TRF)

There was something faintly amusing about the rash of media reporters roaming the empty wet and windy streets of New York and Long Island last weekend. While directors back at base repeatedly ran the same shot of the wooden shed being tossed by waves off Long Island, for the frontline reporters, it must have felt like somebody had, quite literally, stolen their broadcasting thunder.
But the fact that a severe weather event had threatened the very capital of capitalism was not an opportunity to be spurned. Whether the media over-hyped the approaching menace or not is for others to decide. But as the upcoming weather ‘event’ was downgraded to a tropical storm, for quite a few in the mass media, if it was not to be apocalypse now, it could at least be the harbinger of climate apocalypse…er…sometime soon (again).

Yes, There’s A Link Between Hurricane Irene And Global Warming
Let’s cut through the rhetoric and answer the global warming question of the week: Was there a link between global warming and Hurricane Irene? The answer is definitely yes. (Forbes)
Bedrock nitrogen may help forests buffer climate change, study finds
For the first time, researchers at the University of California, Davis, have demonstrated that forest trees have the ability to tap into nitrogen found in rocks, boosting the trees’ growth and their ability to pull more carbon dioxide from the atmosphere.
Given that carbon dioxide is the most important climate-change gas, the nitrogen in rocks could significantly affect how rapidly the earth will warm in the future, the researchers say. They report their findings in the Sept. 1 issue of the scientific journal Nature.
If trees can access more nitrogen than previously thought, that could lead to more storage of carbon on land and less carbon remaining in the atmosphere.
“We were really shocked; everything we’ve ever thought about the nitrogen cycle and all of the textbook theories have been turned on their heads by these data,” said Professor Benjamin Houlton, a biogeochemist and one of the study’s co-authors.
“Findings from this study suggest that our climate-change models should not only consider the importance of nitrogen from the atmosphere, but now we also have to start thinking about how rocks may affect climate change,” he said. (EurekAlert)
U.N. climate boss says Durban talks can deliver
A record rise in global greenhouse emissions and ever tighter economic constraints make it crucial for United Nations climate talks in South Africa in November to overcome years of deadlock and deliver a solution, the U.N.’s climate chief told Reuters.
