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...

Thick smog clouds that loom over Asia threaten the livelihood of crops and contain particles that actually reflect the sun's rays away from the earth, the United Nations reported on Thursday. "One of the impacts of this atmospheric brown cloud has been to mask the true nature of global warming on our planet," United Nations Environment Program (UNEP) head Achim Steiner said at the launch in Beijing of a new report on the phenomenon. Caused by the burning of fossil fuels, wood and plants,...

Human activities are making both Antarctica and the Arctic less icy because of global warming, scientists said on Thursday. An international team published their findings in the recent Nature Geoscience journal. "We're able for the first time to directly attribute warming in both the Arctic and the Antarctic to human influences," said Nathan Gillett of England's University of East Anglia of a study he led with colleagues in the United States, Britain and Japan. The research team measured...

Some 2,000 scientists contributed to the Nobel Peace Prize-winning IPCC report on global warming. Next week, the local contingent will be honored. On the wall of Professor Kirk Smith's office in the School of Public Health hangs an embossed certificate honoring his contributions to the United Nations' Nobel Peace Prize-winning climate-change organization. Because of his groundbreaking work on the deleterious health effects of air pollution caused by indoor cooking and heating fuels around the...
