Transcontinental wildfire emissions monitored from space
05-08-2007 · European Space Agency (ESA)Using data from the SCIAMACHY instrument aboard ESA's environmental satellite Envisat, scientists have determined that the carbon monoxide hovering over Australia during the wildfire season largely originated from South American wildfires some 13 000 kilometres away.

- Coral reefs unlikely to survive in acid oceans
12-14-2007 · EurekAlert!
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean's chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution's Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98 percent of present-day reef habitats will be bathed in water too acidic for reef growth.

- First-ever study to link increased mortality specifically to carbon dioxide emissions
01-03-2008 · EurekAlert!
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

- Local range estimation in wild animals
02-13-2007 · EurekAlert!
A new class of computational methods have been developed to construct distributions of where such monitored organisms are most likely to be found in space and time using this data, and are much more accurate than previous methods when dealing with large sets of data.

- Arizona State scientists keep an eye on Martian dust storm
07-11-2007 · EurekAlert!
Scientists at Arizona State University's Mars Space Flight Center are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a large dust storm on the Red Planet. The dust storm, which erupted during the last week of June 2007, is affecting operations for all five spacecraft operating at Mars: two NASA rovers on the ground plus three orbiters, two of which belong to NASA and one to the European Space Agency.

- Groundbreaking Canada-US study proves link between emissions and mercury pollution in fish
09-17-2007 · EurekAlert!
A Canada-US study to appear in the Proceedings of the National Academy of Sciences proves mercury emissions will end up in fish in as little as three years. It concluded if mercury emissions from industry were cut now, the amount showing up in fish would begin to go down within a decade. Co-author Vincent St. Louis of the University of Alberta says this adds important science to the political debate over emission reductions.

- Space Weather Gear Readied For The Final Frontier
09-29-2006 · ScienceDaily
Atmospheric outflows, auroral emissions and plasma winds? While those aren't terms we hear on the average weather forecast, they cause cosmic storms that rage just outside the Earth's atmosphere and often wreak havoc with telecommunications networks, power grids and other technology essential to Canadian society. Researchers are hoping to gain a better understanding of this "space weather" with a suite of scientific instruments being developed under the leadership of the University of Calgary's Institute for Space Research.

- Toxic releases down from North American industry leaders, increasing from other facilities
10-18-2007 · EurekAlert!
The latest Taking Stock report from the Commission for Environmental Cooperation reveals a continued decline in releases of toxic chemicals to the environment -- 15 percent for the US and Canada from 1998 to 2004 -- driven by a group of industrial facilities that are the largest generators of emissions.The report also, however, reveals a substantial increase in chemical releases and transfers by a much larger group of industrial facilities that report lower emission volumes.

- Mechanoluminescence event yields novel emissions, reactions
05-08-2007 · EurekAlert!
Researchers at the University of Illinois report that a new study of mechanoluminescence revealed extensive atomic and molecular spectral emission not previously seen in a mechanoluminescence event. The findings, which appear online this month in the Journal of the American Chemical Society, also include the first report of gas phase chemical reactions resulting from a mechanoluminescence event.

- Space sensors shed new light on air quality
10-22-2007 · European Space Agency (ESA)
Air pollution is becoming one of the biggest dangers for the future of the planet, causing premature deaths of humans and damaging flora and fauna. With their vantage point from space, satellites are the only way to carry out effective global measurements of air-polluting emissions and their transboundary movement.

- WHRC releases 4 key reports
12-03-2007 · EurekAlert!
As UNFCCC negotiations move towards powerful new mechanisms for compensating tropical countries for their reductions of greenhouse gas emissions from deforestation and forest degradation, important questions remain: How much will REDD cost? Will it benefit forest people? Can forests in chronically cloud-covered countries be accurately monitored? These topics are addressed in four new studies released today by the Woods Hole Research Center in anticipation of the 13th Conference of the Parties of the UNFCCC.
