Arguing climate change to an energy executive
(07/25/2006) Earlier this month I had the opportunity to make a pitch to "Mike," a top executive of a major energy company, about climate change and green energy. Mike said he didn't believe humans are influencing climate or that green energy is a key factor in the future business of his firm, "EnergyCo." I tried to persuade him otherwise, not by focusing on the science of climate change but on economics and market opportunities. It's not that science isn't important--I just didn't want to get caught up in an argument about core beliefs, which is akin to arguing over religion.

Invasive purple flower impacts Iceland's biodiversity
(07/24/2006) A common sight throughout much of Iceland is large fields of vibrant purple nootka, or Alaskan lupine. The flower looks at home in this landscape, but was actually introduced in 1945 to lowland areas as a means to add nitrogen to the soil and also to function as an anchor for organic matter. Lupine has since flourished here, spreading like a wildfire, in almost effortless competition with the other species already in residence. Critics of this initiative view the flower as an invasive species that is threatening low-growing mosses and other native plants.
Corn waste potentially useful for more than ethanol
(07/19/2006) After the corn harvest, whether for cattle feed or corn on the cob, farmers usually leave the stalks and stems in the field, but now, a team of Penn State researchers think corn stover can be used not only to manufacture ethanol, but to generate electricity directly.

China to spend $175 billion on the environment
(07/18/2006) China plans to spend about $175 billion protecting its environment over the next five years according to a report from BBC News. The money will be used to reduce pollution, improve water quality, and cut soil erosion. China has some of the world's most polluted cities and waterways. A December 2005 report from the Chinese government said some 300 million Chinese drink unsafe water tainted by chemicals and other contaminants, while a nationwide survey found that about 90% of China's cities have polluted ground water.
War of words over new climate change report, 'hockey stick' model
(07/16/2006) Paleoclimatologist Michael Mann criticized a report challenging the familiar 'hockey stick' temperature record of the past thousand years. The report, commissioned by Texas Representative Joe Barton, chairman of the House Energy Committee, and championed in an op-ed piece appearing in last Friday's issue of The Wall Street Journal said that there is no evidence that the 1990s were the warmest decade in a millennium or that 1998 was the warmest year in the last 1,000.
Formation of clouds linked to air pollution
(07/13/2006) NASA scientists have determined that the formation of clouds is affected by the lightness or darkness of air pollution particles. This also impacts Earth's climate. In a breakthrough study published today in the online edition of Science, scientists explain why aerosols -- tiny particles suspended in air pollution and smoke -- sometimes stop clouds from forming and in other cases increase cloud cover. Clouds not only deliver water around the globe, they also help regulate how much of the sun's warmth the planet holds. The capacity of air pollution to absorb energy from the sun is the key.

United States economy becomes more carbon efficient
(06/21/2006) The state of Nevada had the largest increase in carbon emissions between 1990 and 2001 according to mongabay.com's analysis of figures released by the Energy Information Administration. Carbon dioxide emissions climbed 47 percent during the period, while the state's economy grew by 85 percent and its population increased by 73 percent. The figures show that Nevada, like the rest of the United States, is becoming getting more out of its carbon dioxide emissions than it did in 1990. Overall the United States was about 20 percent more carbon dioxide efficient in 2001 than in 1990, with each metric ton of carbon dioxide generating from $1,614 to 1,724 worth of gross domestic product.
Venture Capitalists, China and Green Technology
(05/24/2006) A Bay Area venture capitalist with a storied past, has set his sights on "green technology" and ultimately China, after some compelling remarks from state representatives at a recent conference. Early this spring, Chinese officials named solar and clean coal technologies as two of their three pre-eminent priorities for investment and development in the near future. For a country with burgeoning energy needs surpassing what power is presently available, this is both realistic and positive news for environmentalists and economists alike. Hoping to capitalize, John Doerr and his associates are now funneling cash into the emergent green technology sector, which he, and an increasing number of other investors believe to be the next big thing.
