CO2 levels on Earth 15 mln yrs ago were as high as they are todayOctober 9th, 2009 WASHINGTON - In a new research, a scientist of Indian origin has determined that carbon dioxide (CO2) levels on Earth 15 million years ago were as high as they are today. The research was conducted by Aradhna Tripati, a UCLA (University of California, Los Angeles) assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences, and colleagues.
A splash of graphene can improve battery materialsSeptember 23rd, 2009 WASHINGTON - In a new research, scientists have determined that a splash of graphene can improve battery materials. Researchers would like to develop lithium-ion batteries using titanium dioxide, an inexpensive material.
Falling carbon dioxide formed the Antarctic ice-capSeptember 13th, 2009 LONDON - The link between declining carbon dioxide levels and the formation of Antarctic ice caps some 34 million years ago has been established in a major research study. A team of scientists from Cardiff, Bristol and Texas A&M universities worked in Stakishari, a small East African village, to extract microfossils in rock samples which show the level of carbon dioxide at the time of the formation of the ice-cap.
New process can remove sulfur components and CO2 from power plant emissionsAugust 19th, 2009 WASHINGTON - Scientists at the US Department of Energy's Pacific Northwest National Laboratory have developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. The process could directly replace current methods and allow power plants to capture double the amount of harmful gases in a way that uses no water, less energy and saves money.
Indian-American devises cleaner way to capture carbon dioxideJuly 23rd, 2009 WASHINGTON - An Indian-American physicist has devised a cleaner and more efficient way of capturing carbon dioxide from its polluting source, like coal-fired power plants. Lawrence Livermore National Lab (LLNL) researcher Amitesh Maiti has come up with a screening method that would use ionic liquids -- molten salt that becomes liquid under the boiling point of water (100 degrees Celsius) -- to separate carbon dioxide from its source.
Molecule that eats carbon dioxide may fight global warmingJuly 16th, 2009 WASHINGTON - The accidental discovery of a bowl-shaped molecule that pulls carbon dioxide out of the air paves the way for exciting new possibilities to deal with global warming. These possibilities include genetically engineering microbes to manufacture those carbon dioxide "catchers", said J.A.
New isotope cluster could lead to better understanding of carbon cycleJuly 15th, 2009 WASHINGTON - A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change. By analyzing samples of air taken from the stratosphere-the layer of Earth's atmosphere that sits between six and 30 miles above the surface-the team found a much higher concentration of 16O13C18O at high latitudes than expected.
Plants saved planet Earth from freezing over during last ice ageJuly 2nd, 2009 WASHINGTON - In a new research, scientists have suggested that plants may have played a crucial role in putting a limit on the last ice age. When glaciers advanced over much of the Earth's surface during the last ice age, the planet did not freeze over entirely.
Scientists find direct relationship between CO2 emissions and global warmingJune 11th, 2009 WASHINGTON - In a new study, a team of scientists has found a direct relationship between carbon dioxide (CO2) emissions and global warming. The study was done by Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment, along with colleagues from Victoria and the UK.
Increasing CO2 in oceans will make it harder for deep-sea animals to "breathe"April 18th, 2009 WASHINGTON - A new study has suggested that increasing carbon dioxide (CO2) and decreasing oxygen in the oceans will make it harder for deep-sea animals to "breathe". The study, by marine chemists at Monterey Bay Aquarium Research Institute (MBARI), US, suggests that low-oxygen "dead zones" in the ocean could expand significantly over the next century.
Scientists transform CO2 into clean-burning biofuelApril 17th, 2009 WASHINGTON - Scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN) have become the first to transform the greenhouse gas carbon dioxide (CO2) into methanol, which is a widely used industrial feedstock and clean-burning biofuel. The IBN researchers report that by using organocatalysts, they activated CO2 in a mild and non-toxic process to produce methanol, a widely used industrial feedstock and clean-burning biofuel.
CO2 in underground water may bring carbon capture and storage a step closerApril 2nd, 2009 WASHINGTON - A new research has shown that for millions of years carbon dioxide (CO2) has been stored safely and naturally in underground water in gas fields saturated with the greenhouse gas, a finding that brings carbon capture and storage a step closer. Some models predict that CO2 would react with rock minerals to form new carbonate minerals, while others suggest that the gas dissolves into the water.
Wind pattern change may intensify global warmingMarch 14th, 2009 WASHINGTON - Carbon dioxide released from the Antartic Ocean due to shifting wind patterns may drastically increase global warming, say scientists. Many scientists think that the end of the last ice age was triggered by a change in earth's orbit that caused the northern part of the planet to warm.
NASA to launch carbon dioxide tracking satellite TuesdayFebruary 24th, 2009 WASHINGTON - Scientists hope to get a clearer picture of how the Earth reacts to carbon dioxide with the launch Tuesday of a new spacecraft designed to collect data on the climate-changing gas. The Orbiting Carbon Observatory is set for launch early Tuesday from California and will take about eight million measurements every 16 days for the next two years.
Hybrid vehicles could slash carbon dioxide emissions by 2050February 13th, 2009 WASHINGTON - The quantum of carbon dioxide emissions from vehicles anticipated in the year 2050 could be cut down to 2000 levels if all cars on the roads were hybridised, a new study has shown. The study also found that doubling of population density in large US cities by 2050 would have a greater impact on carbon dioxide reductions than full hybridisation of the vehicle fleet.
