University of Calgary climate change scientist David Keith and his team are working to efficiently capture the greenhouse gas carbon dioxide directly from the air, using near-commercial technology.

Leading world scientists convene in Brazil July 21-25 amid growing concern that evaporation and ongoing destruction of world wetlands, which hold a volume of carbon similar to that in the atmosphere today, could cause them to exhale billows of greenhouse gases.

The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR). The findings raise concerns about the thawing of permafrost, or permanently frozen soil, and the potential consequences for sensitive ecosystems, human infrastructure, and the release of additional greenhouse gases.

Scientists at Newcastle University have pioneered breakthrough technology in the fight to cut greenhouse gases.

Australia's first large underground carbon storage facility has opened in the southern state of Victoria. The geo-sequestration plant will capture carbon dioxide from a power station and store it two kilometers beneath the surface. Researchers think the pilot program will help Australia make deep cuts to its greenhouse gas emissions.

Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously, says Professor David Richardson from the University of East Anglia in Norwich, UK, speaking today (Monday 31 March 2008) at the Society for General Microbiology’s 162nd meeting being held this week at the Edinburgh International Conference Centre.

European Union leaders have backed ambitious goals to fight climate change but stressed that they must be affordable at a time of economic downturn.

EU leaders met in Brussels on Thursday and Friday to define a joint solution on how to cut greenhouse gases whilst protecting individual countries’ industries.

The growth in China's carbon dioxide (CO2) emissions is far outpacing previous estimates, making the goal of stabilizing atmospheric greenhouse gases much more difficult, according to a new analysis by economists at the University of California, Berkeley, and UC San Diego.

Scientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and vice-versa.

Swedish agriculture authorities are warning that Swedish farmers ploughing up fields which were earlier bogs or sea beds are releasing large amounts of greenhouse gases into the environment - without even knowing it.

If carbon dioxide emissions from the burning of fossil fuels continue on a "business-as-usual" trajectory, humans will have added about 5 trillion metric tons of carbon to the atmosphere by the year 2400. A similarly massive release of carbon accompanied an extreme period of global warming 55 million years ago known as the Paleocene-Eocene Thermal Maximum (PETM).
