Reducing Cows´ Methane Emissions

That’s why we’re working to change our cows’ diet and help fight climate change.

New Study: Climate Impact Of Grazing Cattle Overestimated

From The Global Warming Policy Foundation Date: 05/06/20 Dr David Whitehouse, GWPF Science Editor The climate impact of grass-fed cattle may have been exaggerated as scientists find emissions of a powerful greenhouse gas from certain types of pasture are lower than previously thought. Researchers from Rothamsted Research found urine from animals reared on pasture where…

Methane emitted by humans vastly underestimated, researchers find

University of Rochester Methane is a powerful greenhouse gas and large contributor to global warming. Methane emissions to the atmosphere have increased by approximately 150 percent over the past three centuries, but it has been difficult for researchers to determine exactly where these emissions originate; heat-trapping gases like methane can be emitted naturally, as well…

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…
