Global climate models `need regional sensitivity`
Global climate change models are of limited use to agricultural policymakers in some regions of the developing world, according to a report by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). The report was launched at the Climate Models and Farm Crop Forecasting in South Asia and Africa meeting last month (21 February). It focused on Eastern and Western ...

Aerosols – their part in our rainfall
“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 atmosphere. Sources of human-generated aerosols include industry, motor vehicles and vegetation ...

Powerful replacement in works for climate-modeling computer
One of the most powerful computers in the world dedicated to climate change, weather and other earth science research will be replaced in 2017 by an even faster machine, officials announced Monday. The Yellowstone supercomputer in Wyoming currently ranks among the 60 fastest in the world. The new supercomputer, to be named Cheyenne, will be at least 2 1/2 times more powerful, the National Center ...

ESRL scientists study California’s water future in a changing climate
Water security is never far from the mind of any decision maker in the U.S. West— but it’s not a terrorist attack on a dam or canal that triggers the most anxiety, it’s climate change. This fall, California Gov. Arnold Schwarzenegger called his state’s water troubles a “holy water war” pitting “north versus south, California versus the feds, rural versus urban....” And well known challenges— the ...

Climate change could be harmful to your health
In an address to the GREENHOUSE 2009 conference in Perth, Australia, Dr Cope said the number of days Sydney experiences temperatures of 30°C or more is projected to increase significantly in the future. “This, in turn, will increase fire risk and associated levels of air pollution,” Dr Cope said. “At higher temperatures, polluting compounds from sources such as motor vehicles or bushfires react ...

Mexico City the Model Megacity for Pollution Study
As one of the world's biggest urban sprawls and home to some of the planet's worst pollution Mexico City makes the ideal subject for a science experiment on a grand scale. Mexico City A team from the USA's National Centre for Atmospheric Research (NCAR) will be leading one of the most complex research projects ever to look at atmospheric chemistry to track the changes in air pollution ...

EPA Awards More Than $4.3 Million in Partnership with NSF and NOAA for Climate and Air Quality Research
Today the U.S. Environmental Protection Agency (EPA) announced more than $4.3 million in grants to 13 institutions to study and improve our understanding of how certain organic compounds form in the atmosphere. Research performed by grantees will help the federal government improve its air quality management systems and climate change models with respect to organic aerosol formation and help EPA ...

Air pollution slows growth of coral reefs in the Caribbean
Periods of slow growth observed in coral reefs in the Caribbean are caused by aerosols in the air from pollution and volcanic activity, recent research suggests. Aerosols cause cooler sea surface temperatures and reduce the amount of sunlight reaching the coral, both of which slow coral growth. Coral reefs are among the world’s most important ecosystems, providing habitats for many marine ...

Defra 2021 Air Quality Model Intercomparison Exercise
CERC are undertaking a project commissioned by Defra in partnership with the Met Office, the UK Centre for Ecology and Hydrology (UKCEH), the Environmental Research Group at Imperial College London and Ricardo in relation to an intercomparison study between models that have the potential to be used for Defra's compliance reporting commitments. Models involved in the intercomparison exercise ...

Air pollution and climate policies not in conflict
Air pollution policy does not undermine the long-term goals of climate change policy, a new study concludes. Although reductions in the pollutant sulphur dioxide could have some warming effects on the Earth’s temperature, the impacts are only short term and will never outweigh climate policy’s cooling effects. Some researchers have raised concerns that air pollution policies may ...

Land use changes in the Mediterranean may be triggering large weather shifts
Land use changes over the last century in the Mediterranean area may be sparking shifts in weather patterns locally, across Europe, and around the globe, suggests a new study. The findings bring to light new complexities that can be integrated into climate models and predictions. The European Commission launched and partially funded1 several major field studies on weather and climate in the ...

Asian Brown Clouds Intensify Global Warming
SAN DIEGO, California, August 1, 2007 (ENS) - Brown clouds of pollution over South Asia have multiplied solar heating of the lower atmosphere by 50 percent, finds new research by scientists at Scripps Institution of Oceanography at the University of California-San Diego. The combined heating effect of greenhouse gases and the brown clouds is necessary and sufficient to account for the retreat of ...

High levels of air pollution to spread across UK
As high levels of air pollution are reported across the UK, NPL's role is to make sure that the measurements of pollutant concentrations are as reliable as possible, so that the right warnings can be given and the most appropriate actions taken. The National Physical Laboratory (NPL) manages much of the infrastructure in place to monitor air pollution around the UK, which helps to provide public ...

More warming will bring a more polluted future
The future is slightly obscured. The outlook is less than clear. For once, such phrases are not metaphorical. A world of global warming could mean a growing haze of solid and liquid aerosols – tiny specks of salt, fine dust, sulphates, black carbon and other particles in the atmosphere, according to new research. Robert Allen, an earth scientist at the University of California, Riverside ...

Air pollution monitoring model takes off in Australia
“The Air Pollution Model (TAPM) increases our ability to pinpoint pollutant behaviour in a wider range of atmospheric conditions,” says CSIRO’s Dr Peter Hurley. ”Over the coming years the new model will continue to fill a gap between simple air pollution dispersion models and the much more complex earth system models such as The Australian Community Climate and Earth-System Simulator (ACCESS).” ...
