Ozone depletion far greater without Montreal Protocol, study shows
NIWA atmospheric scientist Dr Richard McKenzie co-authored the paper with British and Dutch scientists, which is published in Nature Communications this week. Dr McKenzie, whose contribution focused on the ultraviolet radiation calculations, said the paper showed that if allowed to continue unchecked, the ozone hole would have grown by 40 per cent by 2013, which would have contributed to further ...

A new research programme to achieve an improved understanding of the Earth system for the Baltic Sea region
A new international and interdisciplinary research programme, Baltic Earth, is launched. The aim of Baltic Earth is to achieve an improved understanding of the Earth system for the Baltic Sea region, focusing on physical and biogeochemical processes which interact in the atmosphere, in the sea including sea ice, and on land. Human interactions with the environment are recognized as an important ...

Global reductions in mercury emissions should lead to billions in economic benefits for U.S.
Original story at MIT News Mercury pollution is a global problem with local consequences: Emissions from coal-fired power plants and other sources travel around the world through the atmosphere, eventually settling in oceans and waterways, where the pollutant gradually accumulates in fish. Consumption of mercury-contaminated seafood leads to increased risk for cardiovascular disease and ...

Solar cycle not to blame for warming
European scientists have dug deep to dismiss once again the old argument that climate change might be a consequence of solar radiation rather than atmospheric chemistry. The world is warming, they confirm, because more greenhouse gases are getting into the atmosphere, and the changes in the solar cycle are not a significant factor. This is not the first such reassurance. Teams of researchers ...

Travelling slower reduces fuel consumption and nitrogen oxides emissions of ships
Ships that reduce their speed use less fuel, which lowers costs for shipping companies. The slow steaming practice also cuts nitrogen oxides (NOx) emissions. A study found that ships travelling on four European routes lowered their NOx emissions by 12% during the economic crisis of 2008/2009. Shipping continues to be a major way of transporting goods, however, and as the global economy recovers ...

Italian Cruise Ship to Carry Air Pollution Monitoring Station
BRUSSELS, Belgium, November 3, 2005 (ENS) - The European Commission and the Italian cruise line Costa Crociere have launched a new way of monitoring human generated pollution of the atmosphere that the Commission says is essential to improving understanding of climate change. The holiday guests cruising the Mediterranean will probably never see it, but an automatic air pollution monitoring ...

Latest technique in climate forecasts shows decrease in UK summer rainfall
Results from the latest multiple model ensemble techniques in climate change forecasting, published by Britain's Royal Society, indicate that average summer rainfall for northern Europe could decrease by between 5 and 20 per cent by the end of the century. The findings use Met Office Hadley Centre climate simulations in a multiple model ensemble. This method has been pioneered by climate ...

A new global map of ammonia emissions
For the first time, a global map of atmospheric ammonia emissions has been produced using satellite measurements. This opens up new ways to survey air quality and monitor the Earth's atmospheric chemistry from space. Modern agricultural practices, especially intensive farming methods and widespread fertiliser use, are mainly responsible for ammonia emissions, which have more than doubled since ...

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 ...

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 ...

Japan pays high price for ‘silo’ science
Lack of scientific co-operation with other countries has cost Japan “trillions of yen” in expensive solar power because the country did not learn from the experience of other countries before rushing to install it, analysts say. This is one example they give in a report in Nature journal of how much Japan’s economy has lost through the failure of its scientists to involve ...

New insight on the spread of contamination from Fukushima
A study on the transport of radioactive isotopes from Fukushima in the two months after the nuclear incident suggests that they were at official levels of contamination for 34,000 km2 of Japan, and that 2.8% of iodine radionuclides from the event were calculated to have reached the EU. The 2011 nuclear accident at Fukushima, Japan, caused the release of large amounts of radionuclides (unstable ...

Esri Supports Development of UCSB Ocean Use Application
The University of California, Santa Barbara (UCSB), has now officially launched SeaSketch, an ocean planning tool supported by Esri, the world leader in GIS. Conservationists, planners, and ocean resource managers will use the GIS application and Esri's ArcGIS Online to plan sustainable ocean use management. "Helping people make better decisions in the environmental space is extremely ...

Sooty Himalayan snow `warms climate, alters monsoons`
Black carbon landing on snow may be accelerating the melting of Himalayan glaciers more than atmospheric soot or even greenhouse gases such as carbon dioxide (CO2), according to a study. The effects of this carbon, a key component of soot, could change the timing and intensity of the monsoons; increase the chances of downstream floods and reduce farmers' access to irrigation when they most need ...

FL, GA, SC Beaches Face 80-95 Percent Chance of Erosion from Hurricane Matthew
Millions of Americans are currently within Hurricane Matthew’s projected path, and as the powerful storm continues its approach to the Eastern Seaboard residents from South Florida to North Carolina are making preparations for what Matthew may bring. If Matthew’s current track remains constant, one thing is certain - this category four hurricane will bring wide-spread coastal erosion, ...

Climate Services, Observing Systems and Research in Focus at WMO Executive Council
The World Meteorological Organization’s (WMO) Executive Council has agreed on measures to expand and improve research and observing networks to increase understanding of our rapidly changing climate and strengthen delivery of meteorological services vital to society and the global economy. At its annual session 15-23 May, the Executive Council also discussed enhanced disaster risk ...

Radioactive iodine in Arctic sea ice may have European origin
Ninety-eight per cent of radioactive iodine in Arctic sea ice may come from Europe, new research suggests. The study concludes that atmospheric transport of Iodine-129 from European nuclear fuel reprocessing plants is the most likely source. Iodine-129 (129I) is a long-lived (half-life of 15.7 million years) radioactive form of iodine that occurs naturally in very small amounts. It is highly ...

Climate models may be overestimating the cooling effect of wildfire aerosols
Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of the world’s carbon dioxide emissions, which drive up the average global surface temperature. On the ...
