Purdue researchers are developing automotive and portable air-conditioning systems that use environmentally friendly carbon dioxide as a refrigerant. Carbon dioxide is promising for small and light-weight systems, such as automotive or portable air conditioners.
Researchers modeled US ecosystem carbon budget using state-of-the-art data and models, finding small uptake of carbon despite high emissions. The results suggest that ecosystems in the US store carbon, but not enough to balance fossil fuel use, making other regions important for climate change mitigation.
The Earth's oceans are predicted to evaporate within 1 billion years as the sun's temperature increases, leading to a waterless planet. The process is driven by the sun's increasing brightness, which will eventually cause water to evaporate into space.
A new study reveals El Niño dramatically reduced carbon dioxide normally released by the equatorial Pacific Ocean, while also causing extreme biological effects. The research uses data from buoys, ships, and space instruments to monitor ocean productivity and CO2 levels.
A recent study by University of Illinois researchers suggests that including methane in emission-reduction strategies can significantly lower overall costs. The study found that methane can offset carbon dioxide reductions and reduce U.S. abatement costs by more than 25 percent compared to strategies involving carbon dioxide alone.
A Penn State researcher suggests that increasing oxygen levels may have triggered the first of three past episodes when the Earth became a giant snowball, covered from pole to pole by ice and frozen oceans. The study proposes that low methane levels and high carbon dioxide levels were responsible for the glaciation process.
Depleted gas reservoirs can store enough carbon dioxide to limit emissions from fossil fuels for at least 20 years, according to USGS scientist Dr. Robert Burruss. However, capturing, compressing, transporting, and injecting such large amounts of CO2 requires an industry nearly twice the size of the current natural gas industry.
A four-decade study of a Southeastern forest found that while trees take up substantial amounts of atmospheric carbon dioxide, the accumulation in soils is relatively slow. The researchers used radioactive Carbon-14 as a tracer to estimate carbon sequestration and found that only a small percentage of carbon was retained in topsoil, wi...
Researchers found that Loblolly pine trees in North Carolina experienced a 12% growth rate increase when exposed to future carbon dioxide levels. However, the growth rate is likely unsustainable as trees adapt to higher CO2 concentrations and soil nutrient limitations.
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.
The ORNL pellet blaster uses frozen pellets to strip contaminants from surfaces, leaving no residue. This method is safer and more efficient than traditional paint stripping methods, making it suitable for various industries including defense, aerospace, and manufacturing.
A recent study found that high levels of nitrogen deposition in grasslands lead to the loss of plant species diversity and the disruption of ecosystem functioning. Native prairie species are particularly vulnerable to the negative effects of excessive nitrogen addition, which can cause their extinction and reduce carbon storage.
Scientists find that excessive nitrogen deposition in grasslands leads to loss of diversity, extinction of native species, and decreased carbon storage. The study, funded by the National Science Foundation, suggests that nitrogen pollution is a major threat to ecosystem functioning.
Scientists from Brookhaven National Laboratory find that iron supplements can boost phytoplankton productivity, which absorbs 40% of the world's carbon annually. However, adding iron may not have a significant impact on global climate change due to other limiting factors.
