Free and Low-Cost Solar Energy

and has no comments yet.
If solar electricity or solar water heating isn't your cards right now, there are plenty of other ways to take advantage of the sun’s energy–for little or no money. One of the simplest is hanging your wet duds on a clothesline. It only takes just a couple more minutes of your time...

Russia’s fires cause “brown cloud,” may hit Arctic

and has no comments yet.
Smoke from forest fires smothering Moscow adds to health problems of "brown clouds" from Asia to the Amazon and Russian soot may stoke global warming by hastening a thaw of Arctic ice, environmental experts say. "Health effects of such clouds are huge," said Veerabhadran Ramanathan, chair of a U.N. Environment Programme (UNEP) study of "brown clouds" blamed for dimming sunlight in cities such as Beijing or New Delhi and hitting crop growth in Asia. The clouds -- a haze of pollution from cars or coal-fired power plants, forest fires and wood and other materials burned for cooking and heating -- are near-permanent and blamed for causing chronic respiratory and heart diseases.

Biochar

and has no comments yet.
Biochar is charcoal type created by the pyrolysis of biomass, and differs from ordinary charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage. As much as 12 percent of the world’s human caused greenhouse gas emissions could be sustainably offset by producing biochar. That’s more than what could be offset if the same plants and materials were burned to generate energy, concludes a recent study published in the journal Nature Communications. Biochar could sequester carbon in the soil for hundreds to thousands of years.

Deep, Open Ocean Is Vastly Under-Explored, Study Finds

and has no comments yet.
ScienceDaily (Aug. 3, 2010) — New research from the University of Sheffield has discovered that the deep open ocean, by far the largest habitat for life on Earth, is currently the most under-explored area of the sea, and the one we know least about. The research, published in the journal PLoS ONE, has mapped the distribution of marine species records and found that most of our knowledge of marine biodiversity comes from the shallow waters or the ocean floor, rather than the deep pelagic ocean- the water column deeper than the sunlit surface waters but above the sea bed.

7 Hours Sleep Just Right

and has no comments yet.
People who sleep more or fewer than seven hours a day, including naps, are increasing their risk for cardiovascular disease, the leading cause of death in the United States, a study published Sunday shows. Sleeping fewer than five hours a day, including naps, more than doubles the risk of being diagnosed with angina, coronary heart disease, heart attack or stroke, the study conducted by researchers at West Virginia University's (WVU) faculty of medicine and published in the journal Sleep says.

WRI Climate Data Now Available In Google Public Data Explorer

and has no comments yet.

WRI is working with Google to make our data related to climate change more approachable and interactive than ever.

Google's Public Data Explorer is a new tool that makes large data sets easier to understand and explore. Users can reimagine data sets from a growing list of providers (like the U.S. Census, Eurostat, the World Bank, and, now, WRI's Climate Analysis Indicators Tool - CAIT) as interactive charts and maps that illustrate data relationships and trends over time. These new data visualizations can be embedded in other websites and easily shared via email or social networks.

Rising temperatures threaten rice yield growth

and has no comments yet.
Rising temperatures could slow the growth of rice production unless farmers adapt by changing management practices and switch to more heat-tolerant varieties, scientists say. Rice is among the world's most important crops and a staple for people in Asia and Africa, with Asia producing and consuming more than 90 percent of the world's output. A drop in production could lead to higher prices, fears over food security and more hunger in a world with a rising human population. A team of researchers led by Jarrod Welch of the University of California, San Diego, found that rice yields drop as night time temperatures rise over time, although the exact reasons why are not perfectly understood.

Plastic Bag Problems in India

and has no comments yet.
Plastic shopping bags, carrier bags or plastic grocery bags are a common type of carryall used in several countries. Most often these bags are intended for one single use to carry items from a store to a home. Before then paper bags were most commonly used. The real change in grocery bags did not start until 1982, when the two of America’s largest grocery companies Safeway and Kroger started replacing paper bags with plastic bags. These bags are useful and inexpensive but can cause numerous other problems. In India a new concern has arisen.

Accusations of Flawed Climate Science are Rejected by the EPA

and has no comments yet.
Since the Obama Administration came to power in Washington, the EPA has taken upon itself the mission of addressing global climate change. They have been very proactive in getting information out confirming that climate change exists and that it is caused, at least in part, by human activities. Ten petitions were sent to the agency to challenge the EPA's position on climate change. Upon review, the EPA has decided to fully reject the claims made in the petitions, determining that they are without merit.

OPINION: Sanitation Too Often Overlooked in Developing Nations

and has no comments yet.
For most of us, finding a bathroom or toilet isn't hard. Chances are it's not more than a short walk away - you may even be there now. For 2.5 billion people around the world, however, it isn't that easy. Their bathroom is likely shared, has no running water and is a walk from their house. And you thought port-a-potties were bad. The lack of access to sanitation is a huge challenge to the 1 billion people living in urban slums in Africa, Asia and Latin America. The dangers of inadequate sanitation infrastructure are well known - contaminated drinking water and disease transmission become difficult to avoid.
