NASA/Goddard Space Flight Center NASA’s new 3-dimensional portrait of methane concentrations shows the world’s second largest contributor to greenhouse warming, the diversity of sources on the ground, and the behavior of the gas as it moves through the atmosphere. Combining multiple data sets from emissions inventories, including fossil fuel, agricultural, biomass burning and biofuels, and…
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…

University of Southampton A study led by the University of Southampton has mapped several sites in Europe containing gas hydrate – a relatively clean fuel which could help bridge the gap between fossil fuels and renewables. Vast amounts of natural gas are stored in an ice-like form beneath the seabed, under the deep seafloor, close…
Guest essay by By Walter Starck Science is, above all, a search for understanding based on a primacy of reason and evidence, with all findings subject to revision in accord with further evidence or more comprehensive explanation. The highest achievement in science is to discover a new or better understanding that can extend or replace…
By Barry Brill The IPCC’s AR5 estimated the global warming caused by a tonne of livestock methane would be 28 times that of a tonne of carbon dioxide. New research destroys that estimate. The war on meat has been gathering pace amongst our Western elites. The Economist makes a detailed case for “plant-based food” in…
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…
From MIT Technology Review Sustainable Energy Seaweed could make cows burp less methane and cut their carbon hoofprint A diet supplemented with red algae could lessen the huge amounts of greenhouse gases emitted by cows and sheep, if we can just figure out how to grow enough. by James Temple November 23, 2018 In…
The methane! It burns. Seems as if this should be accounted for in GCMs~ctm From Yahoo News UK Rob Waugh Contributor November 20, 2018 It’s a construction project unlike any on our planet: it’s the size of Great Britain, and has been going on for 3,820 years, since the Pyramids were first built. But…
