United Nations Secretary General Ban Ki Moon has warned that without a comprehensive international agreement to reduce the greenhouse gas emissions that lead to global warming, humanity faces "oblivion." "The world's scientists have spoken with one voice: the situation is grim and urgent action is needed," Ban said. "The situation is so desperately serious that any delay could push us past the tipping point, beyond which the ecological, financial and human costs would increase dramatically.

Disease spread to wild bees from commercially bred bees used for pollination in agriculture greenhouses may be playing a role in the mysterious decline in North American bee populations, researchers said on Tuesday.

Converting livestock manure into a domestic renewable fuel source could generate enough electricity to meet up to three per cent of North America's entire consumption needs and lead to a significant reduction in greenhouse gas emissions (GHGs), according to new research.

A Canadian company says that it has developed a way for makers of precast concrete products to take all the carbon-dioxide emissions from their factories, as well as neighboring industrial facilities, and store them in the products that they produce by exposing those products to carbon-dioxide-rich flue gases during the curing process. Industry experts say that the technology is unproven but holds great potential if it works.

A tiny rectangle superimposed on the vast expanse of the Sahara captures the seductive appeal of the audacious plan to cut Europe's carbon emissions by harnessing the fierce power of the desert sun. Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity.

The row over US inaction on carbon emissions reached new heights yesterday after the White House allowed Congress to look at last year's government proposal to officially deem climate change a threat to public health - a plan that aides to George Bush refused to acknowledge or read. The climate plan was finished in December by the US Environmental Protection Agency (EPA) in response to a supreme court ruling that required the Bush administration to state whether carbon emissions should be regulated to protect public health.

Last week, Vice President Al Gore presented the American people with a challenge: meet 100% of our electricity needs through renewable energy within 10 years. Al would be the first to acknowledge this is not a minor task. And yet it is an urgent one, a challenge that will require a transformation in how we invest our time and money, and how we view ourselves.

Toxic waste still plagues American communities 27 years after the U.S. government set up a program to identify and clean up the country's worst sites. A one-year investigation by the Center for Public Integrity reveals the beleaguered state of the Environmental Protection Agency's Superfund effort, uncovers the companies and government agencies linked to the most sites and tracks progress of the clean up.

Britain is trying to water down tough new European legislation to boost the uptake of renewable energy, despite a pledge by Gordon Brown last month to launch a "green revolution" based on clean technology. Documents obtained by the Guardian show the UK wants to block attempts to give renewable electricity sources such as wind farms priority access to the national grid. The European official who drafted the legislation accused Britain of "obstructing" EU efforts on renewables and said UK officials wanted to protect traditional energy suppliers and their coal, gas and nuclear power stations.

Climate change will carry a price tag of billions of dollars for a number of U.S. states, says a new series of reports from the University of Maryland's Center for Integrative Environmental Research (CIER). The researchers conclude that the costs have already begun to accrue and are likely to endure. Combining existing data with new analysis, the eight studies project the long term economic impact of climate change on Colorado, Georgia, Kansas, Illinois, Michigan, Nevada, New Jersey and Ohio. Studies on additional states are in the works.

The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.

Europe's largest onshore windfarm, able to generate enough power for 320,000 homes, has been approved by the Scottish government.

And you thought the U.S. was getting big solar photovoltaic projects (like the one being built by SunPower for FPL, or SunEdison for Duke). But those will deliver just a little more than half of what a Godzilla-like solar PV project in Germany will soon provide. The managing director of solar builder Juwi Solar, Michael Martin, said Juwi has already built over half - or 26 MW - of what, at 40 MW, he claims will be the world's largest solar PV project, which could be completed as soon as the end of the year.

Despite an unstable regulatory environment-renewable energy tax incentives are stalled in the senate, BLM policy has been inconsistent- the United States will surpass Germany to be the largest market for solar power in the world by 2011, according to a report by JP Morgan, cited in Greentech Media. By 2011, the US will have an installed capacity of 1.6 gigawatts (with 920 MW in California alone), surpassing Germany's expected capacity of 1.35 gigawatts. The third largest market by this time will be South Korea with 957 megawatts of capacity.

A team of Chinese scientists has made a chemical breakthrough that efficiently turns the lignin in waste products such as sawdust into the chemical precursors of ethanol and biodiesel.
