Decline in fog threatens California's redwoods
February 15, 2010 05:21 PM - Jeremy Hance, MONGABAY.COM

A surprising new study finds that during the past century the frequency of fog along California's coast has declined by approximately three hours a day. Published in the Proceedings of the National Academy of Sciences the researchers are concerned that this decrease in fog threatens California's giant redwoods and the unique ecosystem they inhabit. "As fog decreases, the mature redwoods along the coast are not likely to die outright, but there may be less recruitment of new trees; they will look elsewhere for water, high humidity and cooler temperatures," explains coauthor Todd E. Dawson, professor of integrative biology and University of California, Berkeley professor of integrative biology with the Department of Environmental Science, Policy and Management (ESPM).

Forecast on Climate Change Legislation Cloudy
February 15, 2010 06:39 AM - Richard Matthews, Global Warming is Real

The President remains committed to advancing his stalled legislative agenda. Addressing the Democratic National Committee in Washington last Saturday, Obama insisted he is not going to let go of his aspirations for America. "I'm not going to walk away from the American people," he said. "I'm not going to walk away on any challenge." However, Senators from Red States, Coal States, and Rust Belt States are concerned about job losses and increased costs associated with a climate bill. Many lawmakers are also concerned about controlling the emissions of rapidly developing nations like India and China.

New error in UN Climate report
February 14, 2010 07:40 AM - Reuters

The U.N. panel of climate experts overstated how much of the Netherlands is below sea level, according to a preliminary report on Saturday, admitting yet another flaw after a row last month over Himalayan glacier melt. A background note by the Intergovernmental Panel on Climate Change (IPCC) said a 2007 report wrongly stated that 55 percent of the country was below sea level since the figure included areas above sea level, prone to flooding along rivers.

Evidence of Rapid Sea Rise Found in Coastal Cave in Mediterranean
February 13, 2010 10:22 AM - Yale Environment 360

An examination of mineral deposits in a coastal cave on the Spanish island of Mallorca shows evidence of rapid rises and declines in sea level as the planet warmed and cooled. Reporting in the journal Science, University of Iowa researchers said that studies of the mineral, calcite — deposited by sea water on the inside of a seaside cave, like rings on a bathtub — showed that roughly 81,000 years ago sea levels jumped by more than 6 feet a century during a warm period, and then dropped during a subsequent cooling cycle at a similar rate — 66 feet per 1,000 years.

How Far the Sun?

Mars is too cold. Venus too hot. Earth is just right in terms of temperature for us to live. How does this all affect climate change? The notion that scientists understand how changes in Earth's orbit affect climate well enough for estimating long term natural climate trends is challenged in a recent study.

Arctic Could be Ice-Free in future Summers
February 11, 2010 07:41 AM - Roger Greenway, ENN

Are warming conditions in the Arctic unprecedented in Earth’s history? It turns out that they are not. The Earth’s climate has gone through warming and cooling times in the past as can be seen in the fossil record that shows tropical species in regions now too cool to support them. These past variations were obviously not caused by the effects of man's activities. This does not mean that the current warming trend is not caused, or affected by anthropogenic air pollution. There is now increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future.

Climate change affecting Kenya's coffee output
February 11, 2010 07:02 AM - Helen Nyambura-Mwaura, Reuters

Climate change has affected Kenyan coffee production through unpredictable rainfall patterns and excessive droughts, making crop management and disease control a nightmare, a researcher said on Thursday. Intermittent rainfall in the 2007/08 crop year, for example, caused a terrible bout of the Coffee Berry Disease that cut Kenyan output 23 percent to 42,000 metric tons as farmers were caught out by rains and did not protect their crop in time. "We have seen climate change in intermittent rainfall patterns, extended drought and very high temperatures," said Joseph Kimemia, director of research at Kenya's Coffee Research Foundation (CRF).

SOLAR-TERRESTRIAL ATMOSPHERIC INTERACTIONS: A FRESH, SPARKY LOOK
February 10, 2010 08:25 PM - Themis Chronis, for ENN

We live in a strongly climate-oriented era, where each one of us is called to choose between sides; are we among the "believers" or the "infidels" of the "Global Warming?". Two decades ago, a part of the scientific community started engaging in intense discussions around the "unusual" temperature trends which, for the northern hemisphere, had been going undoubtedly uphill. The first serious counter arguments regarding the validity of these findings targeted the inherited errors that all observational tools possess. New observations and improved algorithms started to appear fairly quickly, a fact that partially appeased debates and concerns. Skeptics of the global warming theory try to find other kinds of evidence to second-guess the mainstream CO2 increase and steer away from anthropocentric related theories. And suddenly, along came a cloud...

How to Reduce the Fumes
February 10, 2010 07:50 AM - Editor, Sierra Club Green Home

A fresh coat of paint can change a room from dreary to divine. Stains, sealants, caulks, and adhesives help you build everything from a new bathroom to a bookcase. But all these useful products can also introduce unhealthy chemicals into your home and your body. Low-VOC paint The biggest culprit is VOCs, or "volatile organic compounds," a large class of chemicals that readily evaporate at room temperature. If you walk into a room and notice that new-paint smell, you’re breathing VOCs. Paints, stains, sealants, caulks, and adhesives release the highest levels of VOCs when wet. But even when they feel dry to the touch, they may keep releasing these gases for days, weeks, months, even years. Meanwhile your upholstery, carpets, and drapes act like sponges, absorbing VOCs and releasing them over time. While not everyone may be bothered by exposure to these gases, they can be a serious health risk for people with chemical sensitivities, asthma, or other respiratory conditions.

China serious about renewable energy
February 10, 2010 07:15 AM - Reuters

China plans to build a national renewable energy center to enhance the country's clean energy development, the China Daily reported, citing a government official. The center, still at a preliminary planning stage, would be responsible for policymaking, key projects, program management, market operations and international coordination, said Han Wenke, director general of the Energy Research Institute under the National Development and Reform Commission, the country's top economic planning agency, the newspaper reported on Wednesday.
