CSIRO: South East Australia becoming drier, global warming implicated

Submitted by takver on Sun, 24/10/2010 - 9:39pm

A new report into the changing climate of South East Australia and particularly the Murray Darling Basin indicates an increasing risk of below average rainfall and runoff into streams and generally drier conditions. The change in the climate has, at least in part, been attributed to an increase in atmospheric anthropogenic greenhouse gases associated with global warming.

Award for groundbreaking research in capturing carbon dioxide

Submitted by takver on Sun, 29/08/2010 - 12:33pm

A University of Sydney researcher has received an award for groundbreaking work into capturing carbon emissions - research important to mitigating climate change by reducing atmospheric carbon pollution. Dr Deanna D'Alessandro, a postdoctoral fellow based in the School of Chemistry at Sydney University, was awarded a L'Oréal Australia For Women in Science Fellowship for her research on ways to capture and release carbon dioxide, hydrogen and other gases using molecular sponges.

Scientists affirm Australia's climate already changing

Submitted by takver on Tue, 16/03/2010 - 3:43am

In a joint statement released on Monday by the CSIRO and Bureau of Meteorology the stark facts on global warming were outlined: that Australia's climate has already changed with more extremely hot days, fewer cold ones, wetter in the north and drier in the south-east and south-west. The statement outlined in five sections a snapshot of temperature, rainfall, oceans, atmosphere, and what this means for Australia in coming decades.

Climate tipping point: Global Atmospheric Methane on the rise

Submitted by takver on Fri, 08/01/2010 - 4:48pm

The concentration of methane in the atmosphere is rising, according to measurements made by the New Zealand National Institute of Water and Atmospheric Research (Niwa) at its Baring Head Station near Wellington.

Methane (CH4) is a greenhouse gas whose affect on climate is 21 times stronger than Carbon Dioxide (CO2) and is the second most important contributor to global warming behind carbon dioxide. It is produced naturally mainly by biological breakdown of organic substances in oxygen-deficient conditions, such as the digestive system of ruminant animals and the decay of plant material in swamps or landfills. It is also prevalent in fossil fuels such as coal, oil, and natural gas (which is mainly methane).
