Latest Greenhouse gases Stories

A new global-scale modeling study that takes into account nitrogen – a key nutrient for plants – estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen. Researchers at the University of Illinois at Urbana-Champaign and the University of Bristol Cabot Institute published their findings in the journal Global Change Biology. The findings will be a part of the upcoming Fifth Assessment Report from...

Scientists at Lawrence Livermore National Laboratory (LLNL)  and UC Berkeley and have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. Methane is a substantial driver of global climate change, contributing 30 percent of current net climate warming. Concern over methane is mounting, due to leaks associated with rapidly expanding unconventional oil and gas extraction, and the potential for large-scale release of...

ORMOND BEACH, Fla., April 17, 2013 /PRNewswire/ -- CO2Meter.com, a worldwide provider of atmospheric gas measurement equipment, has released independent testing of the SprintIR Carbon Dioxide Sensor by Gas Sensing Solutions Ltd (GSS) in the UK which confirms it is the fastest carbon dioxide sensor in the world. Using a 5% CO2 version of the SprintIR sensor, a vacuum pump and custom software, CO2Meter.com's engineers recorded 20 carbon dioxide level readings per second during normal...

University of California - Santa Barbara Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems. But a group led by a UC Santa Barbara professor has found a point of resilience in a microscopic shelled plant with a massive environmental impact, which suggests the future of ocean life may not be so bleak. As fossil fuel emissions increase, so does the amount of carbon dioxide oceans absorb and dissolve, lowering their pH levels. "As pH...

Brett Smith for redOrbit.com - Your Universe Online A new study suggests that Earth’s atmosphere is largely the product of carbon dioxide gas moving from the mantle to the surface through volcanic activity; if similar activity were to happen on Mars – the planet would be able to sustain liquid water. According to the study, which appeared in the early online edition of Proceedings of the National Academy of Sciences (PNAS), greenhouse gases such as methane and carbon dioxide slowly...

ORMOND BEACH, Fla., March 28, 2013 /PRNewswire/ -- CO2Meter.com, a worldwide provider of atmospheric gas measurement equipment, has developed a new, low-cost combination carbon dioxide and methane gas level meter for use in the biogas industry. It can measure up to 100% methane (CH4) and 50% carbon dioxide (CO2) levels in real time, or can be used as a data-logger to record gas levels over time. The meter is available in 2 versions: as a hand-held, battery-operated device, or in a...

Lee Rannals for redOrbit.com – Your Universe Online About 71-million-years ago, turtles disappeared from Alberta's Drumheller area, and scientists have been blaming dramatic climate change as the culprit. Now, a new theory published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology suggests the real reason was because of habitat changes. Researchers at the University of Calgary studying ancient soil in Red Deer River valley say it was the loss of the wetlands that led...

Lee Rannals for redOrbit.com – Your Universe Online Scientists writing in the journal Science say they have found the first direct evidence of life in the deeply buried oceanic crust. Researchers on board the Integrated Ocean Drilling Program's (IODP) research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. After examining rock samples from this depth, they were able to uncover...

After more than 10 years' work, scientists at the University of Granada have a developed a carbon gel that enables CO2 to be turned into hydrocarbons by electro-catalytic transformation. Researchers from the University of Granada (UGR) have developed a new material using doped carbon that allows low-cost energy to be produced and also reduces the amount of CO2 released into the atmosphere. The recently-patented material is a gel that enables the CO2 to be turned back into hydrocarbons via...

Enid Burns for redOrbit.com – Your Universe Online A group of scientists at Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia's national science agency, have created a "solar sponge" using a metal organic framework (MOF) that absorbs carbon dioxide, but releases it when exposed to sunlight. The journal Angewandte Chemie published a paper detailing MOF. The interaction is known as dynamic photo-switching. The capture-and-release method of dynamic...
