Here’s a quote from an article on PlanetSave.com.
Climate Change from Mount Tambora
After the 1815 eruption, the world temperatue dropped a lot, as the volcanic ash rose all the way up to the stratosphere (140,000 feet or 43 kilometers, in total) and spread — “ a stratospheric sulfate aerosol veil remained for years, dimming the sunlight everywhere.” The global temperature the next summer was 0.5 degrees Celsius lower than average (if you believe climate scientists, of course — and why wouldn’t you). For anyone who doesn’t follow climate science discussions, a change in the climate of 0.5 degress Celsius is significant.
A change of 0.5 degrees Celsius or almost 1 degree Fahrenheit is an average over the entire planet. That may not seem like a lot, but as an average over the entire globe it is significant. In 1816, it was powerful enough to create “The Year Without a Summer.” Mount Pinatubo, in the Phillipines had a similar effect in 1991.
As a comparison, models show that if countries acted on the Kyoto Protocol spending trillions of dollars over the rest of the century as the UN sponsored IPCC (Intergovernmental Panel on Climate Change) recommends we would lower the temperature of the planet by less than 1 degree Fahrenheit. We can spend a lot of money changing the climate very little over 100 years. A volcanic eruption of the nature of Tembora or Pinatubo could essentially have that effect in a long weekend.

Wired Magazine posted a great article about the future of the lightbulb and how it relates to the US Energy Independence and Security Act that is supposed to take effect in 2012.
There’s an excellent reason LEDs have taken on the aura of inevitability: LEDs are semiconductors, and like all solid-state technology, they are getting better and cheaper on a predictable curve. In 1999, a researcher named Roland Haitz, then heading up semiconductor R&D at Hewlett-Packard, coauthored a paper that became the lighting industry’s manifesto. By charting the historical prices of LEDs and projecting forward, Haitz estimated that the amount of light they produced would increase by a factor of 20 per decade, while the cost would correspondingly drop by a factor of 10.

The Obama administration is abandoning its plan to immediately tighten air quality rules nationwide to cut reduce emissions of smog-causing chemicals after an intense lobbying campaign by industry, which said the new rule would cost billions of dollars and hundreds of thousands of jobs, officials said Friday.
The Environmental Protection Agency, following the recommendation of its scientific advisers, had proposed lowering the so-called ozone standard from that set by the Bush administration to a new stricter standard that would have thrown hundreds of American counties out of compliance with the Clean Air Act. It would have required a major effort by state and local officials, as well as new emissions controls by industries and agriculture across the country.
The more lenient Bush administration standard from 2006 will remain in place until a scheduled reconsideration of acceptable pollution limits in 2013, officials indicated Friday.
Bjorn Lomborg recently wrote an op-ed about the current attempt by Republicans in the US Congress to roll back America’s effort to ban incandescent bulbs, here from the Slate magazine: A Dim Bulb of an Idea.
COPENHAGEN Amid a growing wave of concern about climate change, many countries including Brazil, Australia, the United States, and the members of the European Union passed laws in the 2000 s outlawing or severely restricting access to incandescent light bulbs. The intention was understandable: if everyone in the world exchanged most light bulbs for energy-efficient compact fluorescent light bulbs (CFLs), we could save 3.5% of all electricity, or 1% of our CO2 emissions.

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.
