West Lafayette -
The furor over fracking took a further twist this week as levels of the greenhouse gas methane were found above drilling wells, in some cases, 1,000 times greater than previous Environmental Protection Agency estimates.

Kangaroos and cows share a similar diet – mostly grasses and other vegetation. Yet, kangaroos give off a relatively low-methane gas whereas cows and other livestock are a major source of the greenhouse gas.

A new study is examining the possibilities of adapting cattle husbandry and the selection processes for cow breeding, to lower the greenhouse gas emissions produced when cows beak wind.

Scientists have looked at how bacteria work together to anaerobically digest biomass to produce methane gas, which is important in bioenergy and could be linked to the new generation of biofuels.

Yoko Ono and her son, Sean Lennon, started a petition against fracking in New York. They were then invited to visit communities in Pennsylvania to see the actual impacts and effects of fracking, up close and personal.

Thawing of permafrost is expected to cause significant additional global warming, not yet accounted for in climate predictions, warn scientists attached to the United Nations Environment Programme (UNEP) in a report released this week..

NASA’s Curiosity rover sampled the air on Mars this week. At a teleconference on November 2, NASA announced Curiosity had not found any evidence of methane, which is often a sign of life, in the Martian atmosphere.

New research suggests that large volumes of greenhouse gases, like methane, are locked beneath the ice-covered regions of the Antarctic.

Dangerous levels of methane have appeared in water supplies in Leroy Township, Pennsylvania. The appearance of the gas appears to be the result of fracking activities, leading to a fine being levelled on the well operator Chesapeake Energy.

A study conducted by the journal Current Biology suggests that dinosaur flatulence may have been a source of global warming.

Warming permafrost softens coastlines, making it more vulnerable to wave action and promoting erosion along
the Arctic coast of Alaska. A large block of ice-rich permafrost has detached from the mainland and will quickly disintegrate
