Researchers find 24 species believed new to science in Suriname rainforest

...rldwide contributes 20 percent of the total carbon emissions into the atmosphere, more than all the world’s cars and trucks, making conservation of the Amazon rainforest a crucial strategy for minimizing climate change. The burgeoning global carbon market creates new economic value for carbon stored in standin...

Dirty snow may warm Arctic as much as greenhouse gases

More recycling on the farm could reduce environmental problems

...ty of biological resources, curtail greenhouse gas emissions and groundwater contamination, and reduce farming's reliance on oil imports and water. A switch to regenerative agriculture would involve a variety of changes, including reduced use of inorganic fertilizers and more on-farm energy generation from wi...

Confirmed -- deforestation plays critical climate change role

... tropics accounts for nearly 20 per cent of carbon emissions due to human activities," Dr Canadell says. "This will release an estimated 87 to 130 billion tonnes of carbon by 2100, which is greater than the amount of carbon that would be released by 13 years of global fossil fuel combustion. So maintaining for...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

..."They’re added to global effects of greenhouse gas emissions that affect climate change. The take-home message is that we can accelerate the recovery rate of coral reefs by adapting human behavior and reducing local pressure on reefs; this research provides encouragement and incentive for local management. ...

Biodiesel study targets cleaner air, cleaner engines

...l efficiency. Environment Canada monitored exhaust emissions from tractors at the trial sites, including levels of carbon dioxide, nitrogen oxides and particulate matter. Although commercially available, biodiesel has never been tested on agricultural machinery in Canada and has not yet been widely used by...

A third technology, single molecule fluorescence coincidence, was used in an unusual way-to prove t...

New biofuels process promises to meet all US transportation needs

... Sequestering would involve pumping carbon dioxide emissions into saltwater aquifers and hollow underground pockets that used to contain oil, natural gas and coal deposits. But the procedure poses several potential pitfalls. "Clearly, massive quantities of carbon dioxide would be sequestered during a centur...

Ethanol vehicles pose a significant risk to human health, study finds

...added. ''These vehicles produce virtually no toxic emissions or greenhouse gases and cause very little disruption to the land-unlike ethanol made from corn or switchgrass, which will require millions of acres of farmland to mass-produce. It would seem prudent, therefore, to address climate, health and energy w...

...call for increased biofuel production is to reduce emissions of greenhouse gases, not because we are running out of fossil fuels, he added. ''There are reserves of coal for 200 years at least, and coal can be liquefied into fuel, but it produces an awful lot of CO2,'' he explained. Biofuels, on the other ha...
