Research Shows Ocean Iron Ferilization Costly and Ineffective

Written by , on December 14, 2012

Daniel Harrison, a postgraduate research engineer at the University of Sydney, has published results of research demonstrating that fertilisation of the ocean with iron does not store carbon long enough to be an attractive contributor to climate management. Ocean iron fertilisation is a process that attempts to encourage phytoplankton growth in regions with unused nutrients […]  Read more »

Simulating Climate Change in Woodlands

Written by , on May 15, 2012

Scientists at the University of Western Sydney have embarked on a large-scale study of how the natural environment would cope with the atmospheric conditions which are expected if if no significant action is taken to reduce carbon emissions. The centrepiece of the study is six fibreglass and steel ring structures 28 metres high and 25 […]  Read more »

More Accurate Measures of Melting Icecaps

Written by , on February 15, 2012

U.S. scientists using satellite data have established a more accurate figure of the amount of annual sea level rise from melting glaciers and ice caps. There are more than 160,000 glaciers and ice caps worldwide but annual changes in mass have been directly measured for only 120 of them and, in most cases, only within […]  Read more »

Just in case you’re still not sure that the climate is behaving a little strangely, in 2011: Greenhouse gases rose to record levels; Temperatures were the 11th highest ever recorded; The Arctic Sea ice melt almost equalled the 2007 record; The world had its 300th consecutive month of above average temperatures; North America experienced massive […]  Read more »

New Climate Model Claimed To Be More Accurate

Written by , on December 1, 2011

A study published in Science journal, claims to have narrowed the range by which the world’s temperature can be expected to rise with a doubling of carbon dioxide concentrations from pre-industrial levels. Earlier studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2007 report, have precicted a rise of between 2.0°C and 4.5°C, with a […]  Read more »

New Research Estimates Larger Sea Level Rise

Written by , on May 9, 2011

In 2007, the IPCC projected a maximum sea level rise of 59 centimetres by 2100. The IPCC acknowledged that this was likely to be an under-estimate because understanding of the processes happening on ice sheets was inadequate to enable reliable estimates to be made. A team of researchers led by Eric Rignot from Nasa’s Jet […]  Read more »

Greenland Ice Sheet Not Slipping into the Sea

Written by , on January 27, 2011

Until now, it had been thought that melting ice could form a slippy layer at the bottonm of the Greenland ice sheet causing it to slide rapidly into the sea. Now, a study by Professor Andrew Shepherd of the University of Leeds, has shown that this is not happening. Professor Shepherd’s team used satellite imagery […]  Read more »

Global Temperatures Continue to Rise

Written by , on January 13, 2011

NASA’s Goddard Institute for Space Studies, the UK Met Office Hadley Centre and the US National Oceanic and Atmospheric Administration’s National Climatic Data Center have all reported that 2010 was the warmest year (equally with 2005) since global records were begun in 1880. This is NASA‘s updated graph of global temperatures from 1880 to 2010.  Read more »
