Big fuel users such as airlines, miners and rail transport firms may opt-in to Australia's carbon pricing scheme to help manage their carbon costs, the government said on Wednesday.

Scientists have yet to discover, or classify, about 90 percent of the plant and animal species on Earth, which is estimated to be home to just under 9 million species, a study says.

Atmospheric levels of methane, 20 times more powerful than carbon dioxide (CO2) at trapping heat, stayed steady for two decades to 2006 on wider fertilizer use to grow rice or a surge in natural ga

Climate scientists have turned to the United States and Australian navies to deploy robotic measuring devices in the Indian Ocean where pirates have made the area too dangerous for researchers.

About a quarter of the Indian Ocean is now off limits to climate scientists trying to complete a global network of deep ocean devices that gather data crucial to climate change studies and weather foreca

The world's forests can play an even greater role in fighting climate change than previously thought, scientists say in the most comprehensive study yet on how much carbon dioxide forests absorb from the air.

The study may also boost a U.N.-backed program that aims to create a global market in carbon credits from projects that protect tropical forests.

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.

Charlie Bragg gazes across his lush fields where fat lambs are grazing, his reservoirs filled with water, and issues a sigh of relief. Things are normal this year and that's a bit unusual of late.

His 7,000-acre farm near the Australian town of Cootamundra is testament to the plight facing farmers around the globe: increasingly wilder weather is making food production more unpredictable.

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.

Australia's rising liquefied natural gas (LNG) exports may make for bluer skies over Chinese power plants, but back home LNG producers will pump out more carbon emissions than the coal sector.

Natural gas is the cleanest of the fossil fuels when it is burned, so energy-hungry Asian nations are snapping up stakes in LNG projects as they look to guarantee fuel supplies to meet fast-growing energy
