The Smithsonian Tropical Research Institute will expand its research capability with a new Global Earth Observatory system, increasing the quality of scientific data across 20 large-scale research plots in 17 countries. The grant will enable the Center for Tropical Forest Science to compare climate change and forest carbon data.
Scientists at Harvard University discover deep-sea sediments can permanently store man-made carbon dioxide, with US seafloor holding vast reserves. The method involves injecting CO2 into sediment layers, creating a stable and secure storage system.
Research papers explore the effects of glacier shrinkage on alpine uplift, challenge previous theories on the mantle transition zone, and use stratospheric oxygen/nitrogen ratios to constrain carbon uptake budgets by the biosphere and ocean. Mineral dust aerosol emission is also enhanced by electric forces.
Dutch citizens rated various energy technologies with CO2 storage as having consequences between 6.0 and 6.5, indicating acceptance. Informed opinions were more stable than uninformed ones, which were deemed 'pseudo opinions' that don't reflect public acceptance.
Researchers have developed a remote-sensing technology that uses the spectral quality of light reflected from plant leaves to detect gas leaks. This technology can also be used to monitor environmental effects and ensure public acceptability and safety in carbon capture and storage schemes.
A new study by Northeastern University researcher Kevin G. Harrison found that soil carbon levels increased by an average of 14% under elevated CO2 levels. This discovery has the potential to improve global warming forecast models, which have been hindered by slower-than-expected increases in atmospheric carbon dioxide.
A four-year study by the Petroleum Technology Research Centre has concluded that large-scale CO2 storage is safe and can significantly reduce greenhouse gas emissions. The study found that most of the injected CO2 will remain in the reservoir, with minimal risk to overlying water zones or the atmosphere.
The IEA GHG Weyburn project, a $40 million research initiative, involved 24 organizations in Canada, Europe, and the US, producing over 470 deliverables. The project's findings demonstrate the feasibility of large-scale CO2 capture and storage.
A new report finds that nitrogen availability is a critical factor in ecosystem carbon storage, with current limitations hindering the natural systems' ability to mitigate climate change. The study suggests that we need to incorporate these limits into our models and reduce our reliance on natural ecosystems to combat carbon emissions.
A Duke University study found that carbon dioxide-enriched air accelerates pine tree reproduction, resulting in earlier maturation and higher seed production. This trend may have significant implications for forest regeneration and the Southeast's economy, where loblollies are a crucial forest product.
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.
