The accelerating dash for natural gas risks a bitter backlash as the environmental cost of exploiting new shale deposits and of transporting it in liquid form spoil its credentials as the greenest fossil fuel.

Gas was long regarded as a "bridging fuel" for use in relatively easily-to-build, gas-fired power plants, until enough renewable or low-emission nuclear power could be achieved.

Wetlands, forests and farmlands soak up large amounts of carbon dioxide but rising amounts of the gas in the atmosphere mean these carbon "sinks" could become less effective at fighting climate change.

Scientists say land ecosystems are an essential brake on the pace of climate change because plants soak up large amounts of carbon dioxide (CO2) as they grow.

Australia is considering awarding carbon credits for killing feral camels as a way to tackle climate change.
The suggestion is included in Canberra

An irreversible climate tipping point could occur within the next 20 years as a result of the release of huge quantities of organic carbon locked away as frozen plant matter in the vast permafrost region of the Arctic,scientists have found.
Billions of tons of frozen leaves and roots that have lain undisturbed for thousands of years in the permanently frozen ground of the northern hemisphere are

Australia's huge cattle herd in the north might be burping less planet-warming methane emissions than thought, a study released on Friday shows, suggesting the cows are more climate friendly.

Cattle, sheep and other ruminant livestock produce large amounts of methane, which is about 20 times more powerful at trapping heat than carbon dioxide.
