Researchers attribute decrease in atmospheric carbon monoxide levels to reductions in manmade emissions, consistent with trends reported by the EPA. The study found a significant decrease of around five parts per billion by volume in carbon monoxide concentration levels at Big Meadows in Shenandoah National Park, Virginia.
Researchers developed a novel afterburner technology that increases waste consumption in marine incinerators by a factor of 3.2 while reducing carbon monoxide emission by the same amount. The technology also eliminated visible smoke emission during operation.
CSIRO scientists have measured a minuscule decline in oxygen over the past 20 years, which has shed new light on the role of forests and oceans in absorbing carbon dioxide. The oxygen reduction, just 0.03%, is negligible for human breathing but highlights the importance of plant life in capturing half of the CO2 generated by fossil fuels.
Researchers at the University of Toronto found a strong correlation between high weekend ozone levels and one degree Celsius higher temperatures. This challenges the assumption that ozone has a minor impact on greenhouse warming compared to carbon dioxide.
A recent study found that Duke Forest plots experienced a 25% growth increase over two years under high carbon-dioxide conditions. This suggests that forests could serve as a significant carbon sink, potentially offsetting half of the world's expected carbon dioxide emissions from fossil fuel combustion.
New research suggests that increased Arctic temperatures due to global warming can lead to higher levels of carbon dioxide emissions, fueling global warming further. The study found that artificially elevating summer temperatures in arctic tundra resulted in significant losses of carbon dioxide from the soil.
A cost-effective method to eliminate methane emissions from coal mines has been developed by Natural Resources Canada. The system uses a secret catalyst to oxidize methane to water and CO2, generating heat and electricity in the process.
Researchers continuously monitored carbon dioxide flux at a 35-acre tree-kill area near Horseshoe Lake, discovering daily cycles that defy temperature explanation. The data suggests barometric pressure oscillations and Earth tides may influence the degassing rate, highlighting the complexity of volcanic gas emission.
A new study by the Swedish Environmental Protection Agency reveals that diesel cars emit significantly more nitrogen oxides, particulates, and carcinogenic substances than petrol-driven cars. This trend is counterproductive to achieving environmental goals for cleaner air and reduced acidification and eutrophication.
Scientists at Duke University and colleagues found that high CO2 levels can increase tree growth rates, but the effect is likely temporary. The experiment, which mimics future CO2 levels, shows a 12% increase in forest growth, but growth rates are expected to decline over time as the forest adjusts.
A recent USGS study found that a subalpine wetland in Colorado's Rocky Mountain National Park was a net source of carbon to the atmosphere during a two-year period, despite being a net carbon sink for thousands of years. The study suggests that climate change may be affecting the carbon balance of these wetlands.
A conference of 800 environmental scientists explores whether terrestrial ecosystems can slow down climate change by absorbing CO2. Recent technological developments, such as Free Air CO2 Enrichment technology, improve our ability to study carbon storage at the ecosystem level.
Researchers at Penn State found that northeastern Yellowstone mudpots emit significantly higher levels of carbon dioxide, up to 32,000 grams per square meter per day. This discovery contradicts previous assumptions that active geysers were the primary source of CO2 emissions.
A team of researchers found that the fairness of final economic outcomes does not significantly rely on the fairness of initial allocation methods. They suggest alternative fair and acceptable rules for sharing cost burdens while ensuring cost-effectiveness. Developing countries must prioritize equitable outcomes, mitigate costs, and p...
New RFF issues brief examines interactions between climate change policies and the tax system. Research suggests that reducing carbon emissions may produce economic benefits when revenues from pollution control are used to reduce other taxes, potentially offsetting added costs. However, policy approaches can significantly impact costs.
Research by University of Georgia forester Dr. Bob Teskey and colleagues found that managed timber stands can benefit from higher CO2 levels due to improved photosynthesis. The study's results suggest pine trees are better adapted to increased CO2, with positive responses from other species as well.
Researchers discover large areas of non-volcanic carbon dioxide vents in Italy, contributing significantly to atmospheric CO2 levels. The 200-mile area between Florence and Naples produces an enormous amount of carbon dioxide, but its measurement has never been attempted before.
A Duke University study suggests that plants may shunt excess atmospheric carbon dioxide into groundwater to remain stored away for thousands of years. This could help solve the mystery of missing CO2 in the atmosphere and potentially lower predicted impacts of global warming.
