From NASA June 23, 2019 This week, NASA’s Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission — about 21 parts per billion units by volume (ppbv). One ppbv means that if you take a volume of air on Mars, one billionth of the volume of air…
The discovery of genes responsible for asexual reproduction in a tropical grass may reduce negative impacts of cattle farming. The grass captures carbon, reduces gas emissions from soils, restores degraded land, and improves cattle health and productivity International Center for Tropical Agriculture (CIAT) Cattle are a mainstay for many smallholders but their farms are often…
Lots and lots of implications for climate models and GHG budgets. From New Phytologist Kristofer R. Covey J. Patrick Megonigal First published: 06 December 2018 https://doi.org/10.1111/nph.15624 Summary Forest ecosystem methane (CH4) research has focused on soils, but trees are also important sources and sinks in forest CH4 budgets. Living and dead trees transport and emit…
From EurekAlert! Public Release: 3-Jan-2019 Melting ice sheets release tons of methane into the atmosphere, study finds University of Bristol Melting ice sheet release tons of methane into the atmosphere, study finds The Greenland Ice Sheet emits tons of methane according to a new study, showing that subglacial biological activity impacts the atmosphere far more…
Guest essay by Eric Worrall The United States Court of Appeals for the District of Columbia Circuit has rejected a motion to delay implementation of Obama era methane emission laws which limit allowed emissions from oil and gas drilling. Court rejects Trump’s delay of EPA drilling pollution rule BY TIMOTHY CAMA – 07/03/17 01:40 PM…
Guest post by Reed Coray The following example illustrates the issues I have with reasoning often used to argue that increasing the amount of CO2 in the Earth’s atmosphere will increase both the Earth’s surface temperature and the Earth’s atmosphere temperature. Immediately following is a direct quote from URL http://www.school-for-champions.com/science/heat_transfer_earth.htm “The present situation is that…
I’m taking a blog holiday this weekend. Right now I’m watching the History channel 2 (H2) while some off the rails eco-scientist explains to us why we are all going to die because of “what might happen if a gigantic methane-gas explosion occurred in the Pacific.” Methane Explosion (2007) watch the video:
From the USDA, via Eurekalert. The goal was quantifying the moo. Next step, regulation. Hello $10/gallon milk. In the first detailed study on emissions from large-scale dairies, ARS researchers found that a commercial dairy with 10,000 milk cows generated an average of 3,575 pounds of ammonia, 33,092 pounds of methane, and 409 pounds of nitrous…
Via Eurekalert: Measuring methane Researchers develop technique to measure methane gas from cattle MADISON, WI, MARCH 1, 2011 – Methane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related…
