Biodiesel won't drive down global warming
EU legislation to promote the uptake of biodiesel could increase rather than decrease greenhouse gas emissions. A study reported in C&I revealed that while petroleum diesel emits 85 percent of its greenhouse gases at the final stage, in the engine, two-thirds of emissions produced by rapeseed derived biodiesel occur during farming -- cropland emits nitrous oxide, which is 200-300 times as potent a greenhouse gas as CO2. (2007-04-23)

By itself, abundant shale gas unlikely to alter climate projections
A Duke policy analysis appearing in Environmental Science and Technology finds that if natural gas is abundant and less expensive, it will encourage greater consumption of gas and less of coal, renewables and nuclear power. The net effect on the climate will depend on whether the greenhouse gas emissions from producing and consuming natural gas -- including carbon dioxide and methane - are lower or higher than emissions avoided by reducing the use of other energy sources. (2014-05-14)

Global food system emissions threaten achievement of climate change targets
Even if greenhouse gas emissions from fossil fuel use in the global food system were immediately halted, the remaining greenhouse gasses otherwise produced from global food production would make meeting the Paris Agreement's target of limiting temperature increases to 1.5° Celsius (C) above preindustrial levels very difficult, a new study reports. (2020-11-05)

Nature: Up to one-third of US in compliance with Kyoto Accords
Even though the United States does not participate in the Kyoto protocol, one-quarter to one-third of the population lives in states, counties or cities that have adopted climate change policies similar to those of the global initiative. Together, these regions are equivalent to 16.9 percent of global GDP, a slightly larger share than Japan, the world's second largest economy. Although the numbers are promising, complying with environmental policies will be challenging for the regions. (2005-11-22)

New Marcellus development boom will triple greenhouse gas emissions from PA's natural gas
Natural gas production on Pennsylvania's vast black shale deposit known as the Marcellus Shale will nearly double by 2030 to meet growing demand, tripling Pennsylvania's greenhouse gas emissions from the natural gas sector relative to 2012 levels, according to a report published today by Delaware Riverkeeper Network. The increase in greenhouse gas emissions will remain steady through 2045 with continued shale gas development, projects the report, 'Lifecycle Greenhouse Gas Emissions Associated with Projected Future Marcellus Development.'

Researchers find increases in nitrous oxide emissions, outpacing global predictions
The term ''greenhouse gas'' is often used interchangeably with carbon dioxide, due to its prevalence in our atmosphere - more than 80 percent of all greenhouse gas emissions, estimates the Environmental Protection Agency. But another greenhouse gas, nitrous oxide (N2O), can have effects with far greater impact. And, according to a recent study, N2O emissions are increasing at a ''devastating'' rate, faster than predictions introduced by the Intergovernmental Panel on Climate Change. (2020-10-08)

Removal of dairy cows from the United States may reduce essential nutrient supply with little effect on greenhouse gas emissions
A suggested solution to increasing food production worldwide while reducing greenhouse gas emissions has been to eliminate or reduce animal production in favor of plant production. In an article appearing in the Journal of Dairy Science, scientists from Virginia Tech and the US Dairy Forage Research Center studied the effects of dairy product removal on greenhouse gas emissions and nutrient availability in US diets under various removal scenarios. (2020-10-15)

Decrease in greenhouse gas emissions linked to Soviet Union's collapse
As the authors posit, the collapse of the Soviet Union led to decreasing meat product consumption, abandonment of cultivated land, and restructuring of food sales chains; which, in turn, elicited a decrease in greenhouse gas emissions. (2019-09-05)

Worldwide increase in methane bubbles due to climate change
Due to climate change, including rising temperatures, more and more methane is bubbling up from lakes, ponds, rivers and wetlands throughout the world. The release of methane -- a potent greenhouse gas -- leads to a further increase in temperature, thus creating a positive feedback loop (also known as a 'vicious circle'). This is the conclusion of a team of biologists led by Radboud University in an article published in Nature Communications on Nov. 22. (2017-11-22)
