Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought, according to leading atmospheric scientist, CSIRO's Dr Leon Rotstayn. "We have identified that the extensive pollution haze emanating from Asia may be re-shaping rainfall patterns in northern Australia but we wonder what impact natural and human-generated aerosols are having across the rest of the country," Dr Rotstayn said. Aerosols are fine particles suspended in the...

According to researchers, Europe's temperatures have risen over the past 30 years due to fewer misty, hazy, and foggy days. The finding could help researchers predict future climate changes. Five to ten percent of the region's warmer temperatures can be attributed to clearer skies and less air pollution says Geert Jan van Oldenborgh, a scientist from the Royal Netherlands Meteorological Institute. "The temperatures in Europe have been going up twice as fast as climate models had predicted in...

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....

British climate scientists said on Tuesday that the coming year is likely to be one of the top-five warmest on record. Despite the continued cooling of huge areas of the Pacific Ocean "” a phenomenon known as La Nina"”the average global temperature for 2009 is expected to be more than 0.4 degrees Celsius above the long-term average. According to researchers at the Met Office, that would make it the warmest year since 2005, as there is also a growing probability of record...

Increased levels of climate change in parts of the northern hemisphere are expected to continue to rise, effectively reducing the likelihood of a "white Christmas," meteorology experts reported on Monday. Even though heavy snow this year will guarantee a white Christmas in many parts of Asia, Europe and North America, a 1.3-degree Fahrenheit rise in world temperatures since 1900 and projected bigger rises by 2100 suggest an inexorable trend. "The probability of snow on the ground at...

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...

Rising Seas, Severe Drought, Could Come in Decades, Says U.S. Report The United States could suffer the effects of abrupt climate changes within decades "” sooner than some previously thought - says a new government report. It contends that seas could rise rapidly if melting of polar ice continues to outrun recent projections, and that an ongoing drought in the U.S. west could be the start of permanent drying for the region. Commissioned by the U.S. Climate Change Science Program, the...

While 2008 will be recorded as one of the coolest years in the past decade, the World Meteorological Organization (WMO) said it is also the 10th warmest since records began in 1850. The global mean temperature for 2008 was 14.3 degrees Celsius (57.7 degrees Fahrenheit), reported climate scientists at the UK's Met Office Hadley Center and Climate Research Unit at the University of East Anglia, who compiled data for the WMO, said. The 10 warmest years on record have all occurred since...

Government researchers said on Thursday that climate changes caused by greenhouse gases are warming the United States. "The continent as a whole is warming, mostly as a result of the energy sources we are using," William J. Brennan, acting administrator of the National Oceanic and Atmospheric Administration, said at a briefing on the nation's climate since 1951. However, there is a "warming hole" where no change occurred in the center of the country, roughly between the Rocky Mountains and...

The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature. New data allow for more accurate predictions of future climate and improved understanding of today's warming. Past warm periods provide real data on climate change and are natural laboratories for...
