Ben Cubby This year is likely to be seen by future historians as the 'beginning of the clean-energy era', according to the chief of Australia's climate commission.
Peter Hannam Australia's big four banks are leading lenders to the massive expansion in coal and gas shipments through the Great Barrier Reef, contradicting their own pledges to curb carbon emissions and preserve...
The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study.
Ben Cubby Carbon dioxide concentrations in the Earth's atmosphere are on the cusp of reaching 400 parts per million for the first time in 3 million years.
Tom Arup Warming over the 20th century produced the hottest global average temperatures in 1400 years, a major scientific research project has found.
Catherine Armitage Since the 1940s ''disposable'' has been used to describe something meant to be discarded after use.
Climate change could get worse quickly if huge amounts of extra heat absorbed by the oceans are released back into the air, scientists say.
Air pollution is an underestimated scourge that kills far more people than AIDS and malaria and a shift to cleaner energy could easily halve the toll by 2030, U.N. officials said on Tuesday.
Peter Hannam As much as $3 billion in wind farm investments may be diverted elsewhere as the state government dithers over guidelines and reporting procedures, developers and suppliers say.
Gerard Wynn Recent extreme heat waves reinforce concerns that the slow pace of action against climate change is inadequate, raising interest in new fixes called geoengineering, but this warrants caution.
Tom Arup Landscape soaked up third of national carbon dioxide emissions over past two decades.
Global warming may have caused extreme events such as a 2011 drought in the United States and a 2003 heatwave in Europe by slowing vast, wave-like weather flows in the northern hemisphere, scientists...
US Energy Secretary Steven Chu, the Nobel Prize winner who shepherded an effort to help spur a clean energy US economy, will step down after a tenure rocked by the failures of some costly government...
The Amazon rainforest is less vulnerable to die off because of global warming than widely believed because the greenhouse gas carbon dioxide also acts as an airborne fertiliser, a study showed on...
Gerard Wynn Climate change will not be a top issue in the United States under President Barack Obama, despite the soaring rhetoric in his Inaugural Address last month.
Ben Cubby WHILE Sydneysiders are saving more water, cutting energy use and recycling more rubbish than they were a decade ago, their environmental footprints could actually be bigger.
A thaw of sea ice floating on the Arctic Ocean last year sent extra plant food to exotic creatures on the deep sea floor in a shift that might leave polar bears hungry at the surface, scientists say..
Black carbon, the soot produced by burning fossil fuels and biomass, is a more potent atmospheric pollutant than previously thought, according to a four-year international study.
Tom Arup THE forecast expansion of Australian coal mining and exports would be the world's second largest contributor of new carbon dioxide emissions from fossil fuels if fully realised, research by...
The energy big cities burn - mostly coal and oil to power buildings, cars and other devices - produces excess heat that can get into atmospheric currents and influence temperatures thousands of miles...
