Mesa, Ariz., is 1,000th city to sign Conference of Mayors' climate change agreementOctober 2nd, 2009 Mesa, Ariz., is 1,000th signer for climate changeSEATTLE — Mesa, Ariz., is the 1,000th city to sign the U.S. Conference of Mayors' climate change agreement.
Climate change will lead to less ultraviolet radiation over northern high latitudesSeptember 16th, 2009 TORONTO - A new study by University of Toronto (U of T) physicists has shown that climate change will lead to less ultraviolet radiation over northern high latitudes. They discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada.
Ozone layer changes may increase UV radiation in tropicsSeptember 16th, 2009 TORONTO - Ozone layer alterations, prompted by climate change, will enhance ultraviolet (UV) radiation in the tropics and Antarctica, according to a discovery by physicists. Climate change is an established fact, but scientists are only just beginning to understand its regional manifestations, said Michaela Hegglin, a physics researcher at the University of Toronto (U-T) and lead study author.
Birds tend to move in response to unfavorable climateSeptember 15th, 2009 WASHINGTON - A new study by biologists at the University of California, Berkeley, has determined that if the climate is not quite right, birds will move rather than stick around and sweat it out. The findings reveal that 48 out of 53 bird species studied in California's Sierra Nevada mountains have adjusted to climate change over the last century by moving to sites with the temperature and precipitation conditions they favored.
Global warming may cause Earth's axis to tilt in coming centuryAugust 21st, 2009 LONDON - A new study has suggested that gloabal warming may heat up oceans to the extent that it could cause Earth's axis to tilt in the coming century. According to a report in New Scientist, the warming effect was previously thought to be negligible, but researchers now say the shift will be large enough that it should be taken into account when interpreting how the Earth wobbles.
Stressed crops emit more methane emissions than previously thoughtAugust 18th, 2009 WASHINGTON - Scientists at the University of Calgary (U of C) in Canada have found that methane emission by stressed crops could be a bigger problem in global warming than previously thought. According to a U of C study, when crops are exposed to environmental factors that are part of climate change - increased temperature, drought and ultraviolet-B radiation - some plants show enhanced methane emissions.
Treelines not universally responding to climate warming as expectedAugust 13th, 2009 WASHINGTON - In a new research, scientists have found that treelines are not universally responding to climate warming by advancing as expected. Treelines are the elevation or latitudinal limits where trees are capable of growth or survival and are considered to be early indicators of climate warming because they are constrained primarily by cold temperatures.
Global warming may make sea level rise between 7- 82 cm by century endJuly 28th, 2009 WASHINGTON - New predictions indicate 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. Placing limits on the amount of sea level rise over the next century is one of the most pressing challenges for climate scientists.
Obama, Brown speak by phone, discuss climate change and economic recoveryJune 27th, 2009 Obama, Brown speak on climate change, economyWASHINGTON — President Barack Obama on Friday spoke with British Prime Minister Gordon Brown to discuss climate change and the global economic recovery. Obama spoke with his counterpart by telephone as part of their ongoing consultations.
US to suffer serious effects from climate changeJune 16th, 2009 WASHINGTON - The US is already being struck by the effects of climate change and the threats will only grow if the world does not speed up its efforts to reduce pollutants blamed for rising temperatures, the US government warned Tuesday. In a much-anticipated report that was compiled over years by US agencies and independent scientists, the government painted a broad picture of the threats that the United States faces from climate change.
Now, effects of changing climate on sheep can be mathematically predictedMay 31st, 2009 WASHINGTON - In a new research, it has been proven that the effects of a changing climate on a population of bighorn sheep can be mathematically predicted. Researchers from Germany, the US, and Mexico studied a population of bighorn sheep introduced to Tiburon island, Mexico, in 1975.
Sea-level rise may pose greatest threat to Northeast US and Canada this centuryMay 28th, 2009 WASHINGTON - A new research has suggested that the melting of the Greenland Ice Sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax and other cities in the northeastern United States and Canada. The researchers suggest that moderate to high rates of ice melt from Greenland may shift ocean circulation by about 2100, causing sea levels off the northeast coast of North America to rise by about 30 to 51 centimeters (12 to 20 inches) more than other coastal areas.
Gingrich says Democratic climate proposal punishes American people with high costs, lost jobsApril 24th, 2009 Gingrich says climate bill will punish AmericansWASHINGTON — Former House Speaker Newt Gingrich says a Democratic proposal to limit global warming pollution will "punish the American people" with higher energy costs and lost jobs. Gingrich appeared before a House subcommittee writing a broad energy and climate bill aimed at cutting greenhouse gases by 80 percent by mid-century.

India, US to maintain dialogue on climate changeMarch 26th, 2009 WASHINGTON - India and the US have agreed to continue their high level dialogue on climate change in the run up to the Copenhagen conference to evolve a new global regime on the issue. The agreement came as Prime Minister's Manmohan Singh's Special Envoy on climate change, Shyam Saran, Wednesday concluded the first high-level interaction with Obama administration on climate change and related matters.
