Putting a green cap on garbage dumps
andfill sites produce the greenhouse gases, methane and carbon dioxide, as putrescible waste decays. Growing plants and trees on top of a landfill, a process known as 'Phytocapping', could reduce the production and release of these gases, according to Australian scientists writing in a forthcoming... view more (2008-11-24)

Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions.   view more (2008-11-20)

Where there's wildfire smoke, there's toxicity
The health threat to city dwellers posed by Southern California wildfires like those of November 2008 may have been underestimated by officials.   view more (2008-11-20)

Glowing Results-Pitt Researchers Use Fluorescence to Develop Fast, Simple Method for Detecting Mercury in Fish and Dental Fillings
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination.   view more (2008-11-19)

MIT: A quicker, easier way to make coal cleaner
Construction of new coal-fired power plants in the United States is in danger of coming to a standstill, partly due to the high cost of the requirement - whether existing or anticipated - to capture all emissions of carbon dioxide, an important greenhouse gas.   view more (2008-11-18)

Nanoparticles trigger cell death?
Nanoparticles that are one milliard of a metre in size are widely used, for example, in cosmetics and food packaging materials.   view more (2008-11-13)

World needs climate emergency backup plan, says expert
In submitted testimony to the British Parliament, climate scientist Ken Caldeira of the Carnegie Institution said that while steep cuts in carbon emissions are essential to stabilizing global climate, there also needs to be a backup plan.   view more (2008-11-10)

Revised theory suggests carbon dioxide levels already in danger zone
If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study published in Open Atmospheric Science Journal by a group of 10 scientists from the United States, the United Kingdom and France.    view more (2008-11-10)

Global warming predicted to hasten carbon release from peat bogs
Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change.   view more (2008-11-07)

Methane gas levels begin to increase again
The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers.   view more (2008-10-30)

Methylmercury warning
Recent studies hint that exposure to the toxic chemicals, such as methylmercury can cause harm at levels previously considered safe.   view more (2008-10-29)

Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego.   view more (2008-10-24)

Nitrous Oxide Emissions Respond Differently to No-Till Depending on the Soil Type
The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics.   view more (2008-10-23)

Greenhouse Gas Auction Revenues Can Help Cut Md. Electric Use Significantly, Says Study
Maryland officials can reduce electricity use in the state significantly by investing revenues from the Regional Greenhouse Gas Initiative (RGGI) cap-and-trade auctions in energy efficiency programs, says a new study from a University of Maryland-led research team. It adds that neighboring states... view more (2008-10-23)

VAMOS Ocean Cloud Atmosphere Land Study
The clouds being investigated in this study are known as marine stratocumulus clouds. They tend to form adjacent to continents where deep, cold, upwelling water reaches the sea-surface.   view more (2008-10-22)

Forest peoples' rights key to reducing emissions from deforestation
Unless based on respect for the rights of indigenous peoples and forest communities, efforts by rich countries to combat climate change by funding reductions in deforestation in developing countries will fail, and could even unleash a devastating wave of forest loss, cultural destruction and civil... view more (2008-10-16)

MIT finds young planets stay hotter longer
Hot, young planets may be easier to spot because they stay that way longer than astronomers have thought, according to new work by MIT planetary scientist Linda Elkins-Tanton.   view more (2008-10-16)

Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes.   view more (2008-10-10)

'Fingerprinting' method tracks mercury emissions from coal
University of Michigan researchers have developed a new tool that uses natural "fingerprints" in coal to track down sources of mercury polluting the environment.   view more (2008-10-09)

RAND study: Alternative fossil fuels have economic potential
Alternative sources of fossil fuels such as oil sands and coal-to-liquids have significant economic promise, but the environmental consequences must also be considered, according to a RAND Corporation study issued today.   view more (2008-10-08)

More research needed to make good on biofuel promise, experts say
While cellulosic biofuels derived from grasses, crop residues and inedible plant parts have real potential to be more efficient and environmentally friendly than grain-based biofuels like corn ethanol, more research and science-based policies are needed to reap these benefits, says an international... view more (2008-10-06)

Survey confirms parents' fears, confusion over autism
The first national survey of attitudes toward autism reveals that a small but significant percentage of people still believe the disease is caused by childhood vaccines. The survey of 1000 randomly selected adults was conducted for the Florida Institute of Technology.   view more (2008-10-03)

More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope.   view more (2008-10-02)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)
