Curiosity Detects Unusually High Methane Levels

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…

Genetic breakthrough on tropical grass could help develop climate-friendly cattle farms

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…

Methane production and emissions in trees and forests

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…

Some thoughts on radiative transfer and GHG's

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…

Open thread weekend

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:

Quantifying the moo

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…

Methane, the other worrisome GHG – coming to a dairy farm near you

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…
