• Does eating less meat lead to decreased Greenhouse Gas emissions?

    Reduced meat consumption might not lower greenhouse gas emissions from a major beef producing region, research shows.

    The finding may seem incongruous, as intensive agriculture is responsible for such a large proportion of global emissions.

    According to research by University researchers, Scotland’s Rural College and Brazilian Agricultural Research Corporation, reducing beef production in the Brazilian Cerrado could increase global greenhouse gas emissions.

  • SpaceX launches Jason-3 satellite to monitor sea levels

    Jason-3, a U.S.-European oceanography satellite mission with NASA participation that will continue a nearly quarter-century record of tracking global sea level rise, lifted off from Vandenberg Air Force Base in California Sunday at 10:42 a.m. PST (1:42 p.m. EST) aboard a SpaceX Falcon 9 rocket.

    Jason-3 is an international mission led by the National Oceanic and Atmospheric Administration (NOAA) in partnership with NASA, the French space agency CNES, and the European Organisation for the Exploitation of Meteorological Satellites.

    "Jason-3 will take the pulse of our changing planet by gathering environmental intelligence from the world's oceans," said Stephen Volz, assistant administrator for NOAA's Satellite and Information Service.

  • How soil frost affects greenhouse gas emissions from Arctic soils

    Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil.

    Soil in the Arctic has for thousands of years gathered large quantities of decomposed organic matter due to the decomposition being slow at the low temperatures in the region. As temperatures in the Arctic are increasing, there is a growing concern that the organic matter stored in the ground will be decomposed and released as carbon dioxide. Such a process would contribute to the ongoing increase in this greenhouse gas in the atmosphere.

  • Warming climate may impact animals' ability to eat some toxic plants

    University of Utah lab experiments found that when temperatures get warmer, woodrats suffer a reduced ability to live on their normal diet of toxic creosote - suggesting that global warming may hurt plant-eating animals.

    "This study adds to our understanding of how climate change may affect mammals, in that their ability to consume dietary toxins is impaired by warmer temperatures," says biologist Denise Dearing, senior author of the research published online Jan. 13 in the British journal Proceedings of the Royal Society B.

  • How much methane IS leaking at Porter Ranch?

    A UC Davis scientist flying in a pollution-detecting airplane provided the first, and so far only, estimates of methane emissions spewing from the Aliso Canyon Natural Gas Storage Facility in Southern California since the leak began on Oct. 23, 2015.

    Those estimates were provided to the California Air Resources Board in November. Pilot and UC Davis project scientist Stephen Conley continues to measure emissions from the still uncontrolled leak, which has displaced thousands of residents in the affluent Porter Ranch neighborhood in northern Los Angeles. On Jan. 6, Gov. Jerry Brown declared a state of emergency in the community.

    To date, Conley estimates that the leak has emitted nearly 80,000 tons of methane, or about 1,000 tons per day.

  • Cloud cover found significant factor in Greenland Ice Sheet melt

    The Greenland Ice Sheet is the second largest ice sheet in the world and it's melting rapidly, likely driving almost a third of global sea level rise.

    A new study shows clouds are playing a larger role in that process than scientists previously believed.

    "Over the next 80 years, we could be dealing with another foot of sea level rise around the world," says Tristan L'Ecuyer, professor in the Department of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison and co-author of the study. "Parts of Miami and New York City are less than two feet above sea level; another foot of sea level rise and suddenly you have water in the city."

  • The Porter Ranch gas leak update

    Senators Kevin de León and Fran Pavley announced a package of new legislation that builds on Gov. Brown’s state of emergency declaration to ensure protections for Californians impacted by the natural gas leak in Porter Ranch. 

    The new legislation will require: 

    • a moratorium on new injections into the Aliso Canyon  storage facility until experts determine it is safe to resume and a study to see whether it makes sense to continue using the facility. (SB 875)
    • that response costs – such as greenhouse gas mitigation, relocation, and emergency response costs – will be funded by the Gas Company shareholders, not the ratepayers who are suffering from this disaster. (SB 876)
    • stronger laws regulating gas storage facilities, including increased inspections and health and safety measures. (SB 877)
    • setting state climate pollution reduction targets and holding polluters accountable for meeting those targets. (SB 878)

  • Recycling on the ropes, France has a plan to fix the industry

    Low raw material costs have dealt a heavy blow to the recycling industry. The French recycling federation (FEDEREC) believes the sector needs a complete overhaul to stay afloat in the coming years.

    FEDEREC published its view of the future of recycling in a white paper entitled "The recycling industry by 2030." In the preface to this 70-page document, a frank discussion of the problems facing the industry and how they might be solved, Corinne Lepage, a Republican politician, evoked a sector "devastated by an oil price that is so low that it is driving us back towards a linear economy, as it is cheaper today to buy primary raw materials than recycled raw materials".

  • Changing climate and reforestation

    For the past six years, researchers at the Universitat Politènica de València (Polytechnic Univeristy of Valencia, UPV) have been studying the performance of twelve Aleppo pine varieties native to different regions of Spain in reforestation campaigns across three national forest areas. Different varieties or genotypes have different levels of resistance to cold and drought, which influence how well they perform in a given geographical region, and researchers wanted to find out which varieties worked best and where.

    To do so, the different national varieties or genotypes were used to repopulate forest areas in La Hunde, Valencia (as the control region), in the drier Granja d'Escarp, Lleida, to the north and further inland in Tramacastiel, Teruel, where the climate is much cooler.

    "The varieties from Inland Levante and La Mancha performed the best overall, while those from further south seem to be perfect for reforestation efforts in regions already affected by climate change," observes Antonio del Campo, researcher at the UPV's Institute of Water and Environmental Engineering (IIAMA).

  • As gas prices fall, consumers going back to less fuel efficient vehicles

    There were high-fives this week from Detroit to Washington, D.C., as carmakers celebrated record auto sales.

    Americans bought 17.5 million cars and trucks in 2015. That's a huge turnaround from 2009, and the Obama administration cheered the rebound as vindication of the president's decision to rescue General Motors and Chrysler from bankruptcy.

    "Because of the policy decisions that were made by this administration to place a bet on those workers, America has won, and our economy has been better for it," White House spokesman Josh Earnest told reporters Wednesday.
