Most Australians believe climate change is happening now and is caused by human activity, according to preliminary results from a new national survey. Preliminary results from the survey by the UNSW City Futures Research Centre for the Australian Climate Change Adaptation Research Network for Settlements and Infrastructure (ACCARNSI) have indicated that a large majority "“ 78 per cent "“ of Australians believe climate change is happening now while a further 14 per cent expect it...

Climate experts say geo-engineers are exploring radical new ways to combat Earth's climate crisis, including fertilizing the seas with iron, scattering particles in the stratosphere to reflect sunlight or building a sunshade in space, AFP reported. However, many of these ideas are contested as risky for the environment and laden with unknowns about cost, practicality and legality. But mainstream scientists who once dismissed these projects are now starting to consider their possibilities....

Fossil coral data and temperature records derived from ice-core measurements have been used to place better constraints on future sea level rise, and to test sea level projections.The results are published today in Nature Geoscience and predict that the amount of sea level rise by the end of this century will be between 7- 82 cm "“ depending on the amount of warming that occurs "“ a figure similar to that projected by the IPCC report of 2007.Placing limits on the amount of sea...

Suffering among the world's poorest people due to climate change is intensifying the need to find ways of adapting to warmer temperatures and potentially more droughts, floods and sea level rise, a University of Arizona professor wrote in a new report by the organization Oxfam International."Because the effects of climate change have unequal impacts, there is a clear need for strategies and funds for adaptation," Diana Liverman wrote in the foreword to Oxfam's July 6 report, "Suffering the...

A U.S. researcher says global warming is expected to cause the sea level along the northeastern U.S. coast to rise nearly twice as fast as global sea levels. And that, said Jianjun Yin, a climate modeler at the Center for Ocean-Atmospheric Prediction Studies at Florida State University, puts New York City at greater risk for damage from hurricanes and winter storm surges. Yin said he has determined there is a better than 90 percent chance the sea level rise along the heavily populated...

 A new study by scientists updating some of the findings of the Intergovernmental Panel on Climate Change (IPCC) 2001 Third Assessment Report finds that even a lower level of increase in average global temperatures due to greenhouse gas emissions could cause significant problems in five key areas of global concern.The study, published in the Proceedings of the National Academy of Sciences, is titled "Assessing Dangerous Climate Change Through an Update of the IPCC 'Reasons for...

According to a top climate scientist, warnings about global warming have not been severe enough. Just over a year ago, the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) issued a report warning of expanding deserts, intense storms, rising sea levels, and an extinction of up to 30 percent of animals and plants due to global warming. A recent study suggests that the report underestimated the severity of climate change over the next century, says a senior member of the IPCC. "We...

The Worldwatch Institute released a new report on Tuesday that advises sweeping changes must be made to limit global emissions by 2050. In its report, titled "State of the World 2009: Into A Warming World," authors say that even a small increase of up to 3.6 degrees F in global temperatures could result in dangerous threats to natural systems. In order to avoid these threats, the report says that world carbon emissions will have to drop to near zero by 2050 and "go negative" after that....

Future increases in wind strength along the California coast may have far-reaching effects, including more intense upwelling of cold water along the coast early in the season and increased fire danger in Southern California, according to researchers at the Climate Change and Impacts Laboratory at the University of California, Santa Cruz. Earth scientist Mark Snyder presented the findings in a poster titled "Future Changes in Surface Winds in the Western U.S. due to Climate Change" at the Fall...
