Safe long-term storage large amounts carbon dioxide in saline aquifers?

ScienceDaily: The carbon dioxide (CO2) at the Bravo Dome gas field in New Mexico is volcanic in origin, and its emplacement began more than a million years ago, not 10 thousand years ago, as previously estimated. Averaged across the reservoir, only 20% of the CO2 has dissolved into the field's saline brine over 1.2 million years, while the rest remains as a free gas trapped by the cap-rock, suggesting that safe long-term storage in geological sites is viable. This study documents the first field evidence for...

Canada: Study explores capture of clean carbon dioxide from landfill gases
2015-05-21 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Vancouver Sun: Local greenhouse grower Village Farms is hoping to extract clean carbon dioxide -- as well as heat and electricity -- from the landfill gases it burns. The Delta-based grower has been burning methane gas from Vancouvers landfill to generate heat and electricity for 12 years at the firms Ladner facility under an agreement with the City of Vancouver and BC Hydro, according to the firms development director Jonathan Bos. But because landfill gas is chemically inconsistent and contains contaminants,...

Carbon dioxide levels reach global milestone
2015-05-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
USA Today: Worldwide levels of carbon dioxide - the gas scientists say is most responsible for global warming - reached a significant milestone for the month of March, the National Oceanic and Atmospheric Administration said Wednesday. The global monthly average for carbon dioxide hit 400.83 parts per million in March, the first time the average surpassed 400 ppm for an entire month since such measurements began in the late 1950s, NOAA said. "It's both disturbing and daunting," said NOAA chief greenhouse...

Global carbon dioxide levels reach new monthly record
2015-05-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: In another ominous sign of human-caused climate change, US government scientists said Wednesday that global carbon dioxide concentrations have reached a new monthly record of 400 parts per million. Carbon dioxide is a potent greenhouse gas, and is a harmful by-product of burning fossil fuels such as oil and coal. "For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million...

Climate milestone reached as global carbon dioxide levels surpass 400ppm
2015-05-07 12:14:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Global carbon dioxide concentrations have surpassed 400 parts per million (ppm) for the first month since measurements began, the latest results from the National Oceanic and Atmospheric Administration (NOAA) show. Scientists have said the record is a significant climate milestone. According to the UN Intergovernmental Panel on Climate Change, the concentration of all greenhouse gases, including methane and other gasses that are not included in NOAAs measurement, must not exceed 450ppm this century...
