Volcanoes Now Blamed for Lack of Global Warming

Editor's Note:  Previously, mainstream media began the slow, tacit admission that global warming hasn't manifested in the way it was so definitively predicted 10 years ago.   This admission was presented last month through a recent study suggesting that √áhina's sulfur emissions were to blame for the lack of global warming.  Floods resulting from late melting mountain snow-packs  offer unique challenges this summer to the country's eroding infrastructure.   Little preparation for anticipated heavy winters will be the norm as the propaganda for disastrous anthropomorphic global warming will only increase in the near future.

If you have a group of environmentalists in your area that refer to global warming as one of the reasons for cool concepts like localization, cleaning up the eco-sphere or reducing automobile exhaust, introduce some of the contradictory information involving climate change and see how they react to you.  Pay close attention to the way they try to  dismiss you or shape the argument away from what you present in support of recent conventional climate research.   See if they actually answer your questions or address the specific points you present.  Turning over this rock may involve an ugly discovery underneath.

Study: volcanoes curbing warming

Volcanic particles high in the atmosphere might have had a cooling effect over the past decade, perhaps easing global warming, a study by the National Oceanic and Atmospheric Administration shows.
The finding could have important implications for projections of future warming as well, the study's authors say.

The scientists examined satellite measurements of sulfuric acid droplets called aerosols in the upper atmosphere, most of which come from volcanic eruptions.

The particles can reflect sunlight back into space, the researchers said, perhaps reducing the warming effects climate scientists say are driven mainly by release of heat-trapping carbon dioxide into the atmosphere by humans.

The study, led by Susan Solomon, an atmospheric scientist who recently retired from NOAA, showed that such particles have been gradually increasing over the past decade.

That was enough to cool the Earth's atmosphere by 0.1 watts per meter squared between 2000 and 2010.

But while it might have blunted the effects of global warming, it would not be enough to overcome the trend; carbon dioxide emissions warmed the planet during the same period by 0.3 watts per meter squared.

A separate NOAA study showed that the 2000s were the warmest decade on record.

"It's almost certain that, without volcanic aerosols in the stratosphere, Earth would be warmer," said Charlie Zender, an Earth System Science professor and atmospheric physicist at UC Irvine. "It did mask some of the warming due to anthropogenic greenhouse gases."

Zender says the idea of mimicking the effects of volcanoes by injecting aerosols into the stratosphere in order to cool the planet should be studied more extensively.

The study on volcanic particles was published this month in the journal, Science.
