Researchers warn that individual countries looking to go it alone with 'cheap' solutions to regional climate change could inflict negative impacts on the rest of world. Large-scale 'geoengineering' interventions to alter the climate, such as increasing cloud cover to deflect solar radiation, may not work on a global scale, a new study has warned.

Global carbon dioxide (CO2) emissions in 2009 fell 1.3 percent to 31.3 billion tonnes in the first year-on-year decline in this decade, German renewable energy institute IWR said on Friday. The Muenster-based institute, which advises German ministries, cited the global economic crisis and rising investments in renewable energies for the fall in emissions. Global investment in renewable installations for power, heat and fuels last year rose to 125 billion euros ($161 billion) from 120 billion in 2008, IWR said. But IWR director Norbert Allnoch said given the force of the crisis, the reductions in CO2 output could have been greater, had stronger output in Asian and Middle Eastern countries not overcompensated the savings obtained from declines in Europe, Russia, Japan and the U.S.

Among the islands in the Eastern Caribbean, St. Lucia’s economy is performing comparatively well. The island, which is less than half the size of Los Angeles proper and is home to about 170,000, is diversifying its agricultural sector, has decent infrastructure, and has attracted investment in its manufacturing and banking sectors. Now this tiny nation northwest of Barbados is making a move on the renewable energy front. St. Lucia’s government has signed an agreement with US-based Qualibou Energy for the development of a geothermal plant. If all goes as planned, the plant will generate 12 megawatts of electricity by 2012, and another 108 MW of capacity will be in operation by 2015.

Following the Greenhouse Gas Tailoring Rule, the US EPA issued a proposed two new rules to address the permitting issues which the tailoring rule created. The GHG Tailoring Rule, specifies that beginning in 2011, facilities that increase GHG emissions substantially will require an air permit. The EPA proposed two rules to ensure that businesses planning to build new, large facilities or make major expansions to existing ones will be able to obtain Clean Air Act permits that address their greenhouse gas (GHG) emissions. The Tailoring Rule covers large industrial facilities like power plants and oil refineries that are responsible for 70 percent of the GHGs from stationary sources. The new EPA proposals are a critical component for implementing the Tailoring Rule and would ensure that GHG emissions from these large facilities are minimized. The Clean Air Act requires states to develop EPA-approved implementation plans that include requirements for issuing air permits. When federal permitting requirements change, as they did after EPA finalized the GHG Tailoring Rule, states likely need to modify these plans.

A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected assembly of solar cells, also known as photovoltaic cells. The solar panel is used as a component in a larger photovoltaic system to offer electricity for commercial and residential applications. There are many methods available to try to increase their output. There is now a new entrant to the realm of solar panel accessories that is said to increase panel performance while decreasing costs. Joining solar trackers and microinverters is a new polymer film called FUSION by Genie Lens Technologies.

The US Environmental Protection Agency (EPA) has successfully completed the cleanup of a superfund site in Long Hill Township and Harding Township, Morris County, NJ. The site, at the edge of a National Wildlife Refuge, had formerly served as an asbestos dump. It has now been removed from the National Priorities List of hazardous waste sites.

On a recent walk along New York City's Union Square Park, I came across a beautiful sight: walking in 95-degree humid heat, I saw fountains and fountains of cold, clean, and free drinking water. New Yorkers profess that their tap water is "the purest and tastiest" in the world. This summer, the New York Department of the Environment is rolling out an environmental education campaign on city streets to inform residents of just that—and to discourage people from buying bottled water.

Some of Russia's smog-causing peatland fires are likely to burn for months, part of a global problem of drained marshes that emit climate-warming greenhouse gases, experts said on Wednesday. Novel carbon markets could offer a long-term fix for peat bogs, from Indonesia to South Africa, if negotiators of a U.N. climate treaty can agree ways to pay to safeguard marshes that are often drained to make way for farms, roads or homes. "Peat fires continue underground and...they will not be extinguished in Russia before winter rains and snow set in," said Hans Joosten, professor of peatland studies and paleoecology at the University of Greifswald in Germany.

Cement plants emit mercury from the kilns used in the cement manufacturing process. Cement kilns operate at high temperatures, and are, in fact used to destroy many types of toxic substances. The rule, proposed on August 9, 2010 also applies to total hydrocarbons (THC), and particulate matter (PM) from new and existing kilns located at major and area sources, and for hydrochloric acid (HCl) from new and existing kilns located at major sources. The standards for new kilns apply to facilities that commence construction, modification, or reconstruction after May 6, 2009 The U.S. Environmental Protection Agency (EPA) issued final rules to cut emissions of mercury, particle pollution and other harmful pollutants from Portland cement manufacturing, the third-largest source of mercury air emissions in the United States. EPA calculates that the rules will yield $7 to $19 in public health benefits for every dollar in costs.

The Gulf of Mexico has been a problem for fishing and other marine life even since the BP oil spill earlier this year. Things are looking up finally. The National Oceanic and Atmospheric Administration (NOAA) has just reopened 5,144 square miles of Gulf waters to commercial and recreational finfish fishing. Since July 3, NOAA data have shown no oil in the newly reopened area, and United States Coast Guard observers flying over the area in the last 30 days have also not observed any visible oil. Even more importantly, fish caught in the area and tested by NOAA experts have shown no signs of contamination.

Ice can exist on the equator, so long as it's at a high elevation. The Indonesian mountain ridge, which rises to 16,000 feet on the island of New Guinea, supports the presence of such an ice field. According to a study by researchers from Ohio State University, that tropical ice field can disappear within a few years. Their studies also offer clues of the El Nino weather phenomenon that dominates climate variability in the tropics.

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...

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 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.

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.

Environmentalists are dismayed at plans by the Tanzanian government to build a major commercial highway through Serengeti National Park The Tanzanian President has vowed to go ahead with controversial plans to construct a major road through the Serengeti, despite fierce opposition from environmentalists and the tourism industry. The 480-kilometre road will link the Lake Victoria area with eastern Tanzania and, according to the Tanzanian government, bring essential economic development to the region - linking remote communities to the major road network, allowing transport of people and goods and connecting farmers with markets.
