DALLAS, May 16, 2013 /PRNewswire/ -- The report "Refrigerant Market - Hydro Chlorofluorocarbons (HCFC), Hydro fluorocarbon (HFC), Hydrocarbon (HC), Inorganic (Ammonia, Carbon dioxide) - Trends & Forecasts to 2018"", defines and segments the global refrigerant market with analysis and forecasting of the global volume and revenue. Refrigerant consumption will grow from an estimated $10.5 billion (equivalent to 1,207 thousand MT) in 2012 to $15.7 billion by 2018, with a CAGR of 6.9%...

Picarro Analyzer Took Historic Measurement on Mauna Loa SANTA CLARA, Calif., May 16, 2013 /PRNewswire/ -- Researchers from SCRIPPS studying atmospheric levels at the Mauna Loa Observatory last week recorded the milestone 400 parts per million (ppm) CO(2) concentration using instrumentation from Picarro Inc. The Mauna Loa observatory is a premier atmospheric research facility, and ideal for monitoring climate change due to the undisturbed air and minimal outside influences atop the...

WASHINGTON, May 2, 2013 /PRNewswire-USNewswire/ -- Environmental Investigation Agency -- Japan has announced new legislation to phase-down the "super" greenhouse gases hydrofluorocarbons (HFCs), joining the European Union and Australia in regulating and phasing down HFCs domestically. The revision of the European F-Gas Regulation to implement a systemic phase-down of HFCs is in full-swing in the EU and Australia implemented a carbon tax on HFCs last year. The United States is the...

Lawrence Berkeley National Laboratory Like the Roman god Janus, methane presents Earth’s atmosphere with two situational faces. As the main component of natural gas, methane when burned as a fuel produces less carbon dioxide than the burning of oil or coal, which makes it a plus for global climate change. However, pure methane released into the atmosphere via leaks from unconventional oil and gas extraction, coal mining or from the melting of Arctic ice is an even more potent greenhouse...

LONDON, April 24, 2013 /PRNewswire-USNewswire/ -- Once again living up to its status as the 'world's most effective environmental treaty,' the Montreal Protocol has struck a deal with China to phase-out hydrofluorocarbon (HCFC) production and so prevent eight billion tonnes of carbon dioxide equivalent emissions. With funding of up to US$385m from the Montreal Protocol's Multilateral Fund, China will eliminate its production of HCFCs, ozone-depleting substances that are also potent...

More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations. David...

Brett Smith for redOrbit.com - Your Universe Online A new technique has allowed a team of British and American scientists to connect temperatures to a massive shift in atmospheric carbon dioxide that occurred around 34 million years ago, according to a new study in the Proceedings of the National Academy of Sciences. Scientists have described this transformation in global climate as a shift from a warm, high-carbon dioxide "greenhouse" condition to a temperate, low-carbon dioxide state...

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...
