Climate change rate over next century could be higher than previously anticipatedOctober 10th, 2009 WASHINGTON - In a new experiment, scientists have found that the rate of climate change over the next century could be higher than previously anticipated. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory (ORNL) and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences.
Obama's top energy adviser says no way Congress can pass climate change bill this yearOctober 2nd, 2009 Obama adviser says no climate change law this yearWASHINGTON — President Barack Obama's top energy adviser says there is no way Congress will be able to pass a bill on climate change this year. "That's not going to happen," the adviser, Carol Browner, said Friday.
Report: Climate change means more hungry children, greater investment in farming neededSeptember 30th, 2009 Report: Climate change means more hungry childrenJOHANNESBURG — Scientists fear climate change will mean 25 million more hungry children over the next four decades, with subsistence farmers in Africa and Asia particularly hard hit by global warming, according to a report issued Wednesday. The authoritative International Food Policy Research Institute said even without climate change, 113 million children under 5 years old will be malnourished in 2050 worldwide.
Pakistan to reverse clocks by one hour from Nov 1September 28th, 2009 ISLAMABAD - The Pakistan government has decided to reverse the clocks by one hour from Nov 1, the Online news agency reported Monday citing the interior ministry. The government had decided to advance the clocks by one hour for seven months from April 1 to Oct 31 every year to overcome the energy crisis, while the clocks would be reversed by one hour from Nov 1 to March 31, the report said.
Future of forests really bleak: StudySeptember 16th, 2009 WASHINGTON - The composition of some of our forests may be quite different 200 to 400 years hence, says a recent study. The study found that temperature and photosynthetic active radiation were the two most important variables in predicting what forest landscapes may look like in the future.
Soon, a portable optical atomic clockSeptember 4th, 2009 BERLIN - In a new research work, a team of scientists has shown how optical atomic clocks in the future might become more compact and even portable, maybe even travel to space. The research was done by scientists from the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany.
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.
Plants under stress emit more methane, worsen global warmingAugust 18th, 2009 TORONTO - Methane emission by plants in dry or drought prone areas could aggravate global warming more than previously suspected, says a new study. A University of Calgary (U-C) study warns that plants exposed to environmental factors -- rising temperature, drought and ultraviolet-B radiation -- show enhanced methane emissions.
Insects' bio-clocks could help more effective pest controlAugust 13th, 2009 WASHINGTON - Researchers have discovered that the circadian rhythms or biological "clocks" in some insects can make them far more susceptible to pesticides at certain times of the day than other. With further research, it may be possible to tap into this genetic characteristic, identify the times that a target insect is most vulnerable to a specific pesticide, and use that information to boost the effectiveness of a pesticide.
Fire and water to unlock 'internal clocks' of archaeological objectsMay 20th, 2009 WASHINGTON - A team of scientists has developed a new way of dating archaeological objects, by using fire and water to unlock their 'internal clocks'. The scientists, from the University of Manchester and the University of Edinburgh, call this technique as 'rehydroxylation dating', which can be used to date fired clay ceramics like bricks, tile and pottery.
Some plants may override the effects of climate change on wildfire occurrenceMay 2nd, 2009 WASHINGTON - A new study has shown that, in some cases, the types of plants growing in an area could override the effects of climate change on wildfire occurrence. The study was conducted by Lawrence Livermore National Laboratory scientist Tom Brown along with Philip Higuera of Montana State University and colleagues.
Plants could override climate change effects on wildfiresApril 22nd, 2009 WASHINGTON - A new study has suggested that in some cases, changes in the types of plants growing in an area could override the effects of climate change on wildfire frequency. Philip Higuera of Montana State University and his colleagues show that although changing temperatures and moisture levels set the stage for changes in wildfire frequency, they can often be trumped by changes in the distribution and abundance of plants.
New technique makes atomic fountains clocks more stableMarch 19th, 2009 WASHINGTON - With the aid of a new method developed by scientists in Germany, the output frequency of the atomic fountains clocks has become more stable. At present, Caesium fountain clocks are the most accurate clocks in the world, furnishing the second accurate to 15 places after the decimal point.
Agulhas Current in southern hemisphere may stabilise or destabilise Europe's climateMarch 12th, 2009 WASHINGTON - New data has emerged that provides evidence in support of the hypothesis that the Agulhas Current, in the southern hemisphere, may stabilise or destabilise climate in Europe. The data was presented by scientist Martinez-Mendez, in her PhD thesis titled "Surface and Deep Circulation off South Africa: Agulhas Leakage Influence on the Meridional Overturning Circulation During the Last 345 kyr".
Hybrid vehicles could slash carbon dioxide emissions by 2050February 13th, 2009 WASHINGTON - The quantum of carbon dioxide emissions from vehicles anticipated in the year 2050 could be cut down to 2000 levels if all cars on the roads were hybridised, a new study has shown. The study also found that doubling of population density in large US cities by 2050 would have a greater impact on carbon dioxide reductions than full hybridisation of the vehicle fleet.
