st week, investigators studying methane leakage levels in Manhattan reported alarming preliminary findings. The gas industry and Con Edison estimate 2.2% leakage in its distribution systems, and at leakage above 3.2%, according to the Environmental Defense Fund, natural gas ceases to have any climate advantage over other fossil fuels.
But the study found an average cumulative leakage of over 5% in natural gas production and delivery. At these levels, natural gas—93% of which is methane—has a far more potent greenhouse gas impact than burned coal or oil, the authors stated.




Ten years after the United States invaded and occupied Iraq, the country’s oil industry is poised to boom and make the troubled nation the No.2 oil exporter in the world. But the nation that’s moving to take advantage of Iraq’s riches isn’t the United States. It’s China.
Widely used pesticides have been found in new research to block a part of the brain that bees use for learning, rendering some of them unable to perform the essential task of associating scents with food. Bees exposed to two kinds of pesticide were slower to learn or completely forgot links between floral scents and nectar.
Scientists have linked the underground injection of oil-drilling wastewater to a magnitude-5.7 earthquake in 2011 that struck the US state of Oklahoma. Wastewater injection from drilling operations has been linked to seismic events in the past, but these have typically been much smaller quakes.
More than half of U.S. rivers, streams and other waterways are in too poor of a condition for aquatic life, the Environmental Protection Agency said. The EPA said most the nation's streams, rivers and other waters were in poor health.
An obscure federal regulator of electricity markets has emerged as a tough cop on the beat, taking on Wall Street banks and big energy firms alike for market manipulation. That aggressive approach stands out when it’s compared with that of the regulator in charge of looking for manipulation in the oil and gasoline markets.
