Current carbon dioxide levels also prevailed 15 mn years agoOctober 9th, 2009 WASHINGTON - You would have to go back at least 15 million years to find carbon dioxide levels as high as they are today, say scientists. Then "global temperatures were five to 10 degrees Fahrenheit higher than they are today, sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland," said Aradhna Tripathi, who led the study.
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.
Current methods for monitoring CO2 emissions have limitationsAugust 1st, 2009 WASHINGTON - A new report has determined that the current methods for estimating greenhouse gas emissions have limitations that make it difficult to monitor CO2 (carbon dioxide) emissions and verify an international climate treaty. This is part of a new National Research Council letter report to the administrator of NASA, Charles F.
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.
Bowl-shaped molecule can capture CO2 from thin airJuly 16th, 2009 WASHINGTON - In a new study, a scientist has said that the accidental discovery of a bowl-shaped molecule that pulls carbon dioxide (CO2) out of the air suggests exciting new possibilities for dealing with global warming, including genetically engineering microbes to manufacture those CO2 "catchers". According to J.
NASA and NOAA'S GOES-O satellite launched successfullyJune 28th, 2009 WASHINGTON - The latest Geo-stationary Operational Environmental Satellite, GOES-O, soared into space Saturday after a successful launch from Space Launch Complex 37 at the Cape Canaveral Air Force Station in Florida. The GOES-O spacecraft lifted off at 6:51 p.m.
With space shuttle launch on hold, NASA unmanned moon rocket aims for Thursday liftoffJune 17th, 2009 NASA aims for unmanned moon rocket launch ThursdayWASHINGTON — NASA plans to launch an unmanned rocket to the moon Thursday, the first such mission in a decade. The space agency announced plans for the Cape Canaveral launch Wednesday after deciding to postpone a space shuttle mission because of a hydrogen gas leak.
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.
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.
Online poll for NASA's greatest hits beginsApril 15th, 2009 WASHINGTON - NASA is inviting the public to vote online for the most important contribution the space agency has made to exploring Earth and improving the way we live on our home planet. NASA is conducting the survey as part of its celebration of Earth Day, April 22.
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's carbon dioxide satellite fails at launchFebruary 25th, 2009 LOS ANGELES - A NASA satellite meant to help scientists get a clearer picture of how the Earth reacts to carbon dioxide failed to reach orbit after launching early Tuesday from an Air Force base in California, NASA said. The $278-million Orbiting Carbon Observatory was meant to take about 8 million measurements every 16 days for the next two years to give researchers a clearer picture of how the carbon cycle affects climate and how net emissions vary by region.
NASA mission to help unravel climate mysteriesJanuary 30th, 2009 WASHINGTON - NASA's first spacecraft dedicated to studying atmospheric carbon dioxide is in final preparation for a Feb 23 launch from Vandenberg Air Force Base in California. Carbon dioxide is the leading human-produced greenhouse gas driving changes in Earth's climate.
