Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

The corresponding climate impacts, however, have been only indirectly evaluated and thus remain largely unquantified. Robert Allen/UCR) Both types of energy—longwave (from Earth) and shortwave (from sun)—escape from the atmosphere more than they are absorbed into it. This in turn reduces the amount of water that evaporates.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years.

HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

The methanol is mixed with water, then evaporated by applying heat and fed into the preheated reactor, where the mix of methanol and water is converted into hydrogen and CO 2. The hydrogen molecules escape through the extremely fine pores of the membrane, while the larger carbon dioxide gas molecules are retained. © Fraunhofer.

New study confirms extensive gas leaks in the North Sea; recommends stricter guidelines for handling of abandoned wells

Green Car Congress

Researchers from the GEOMAR Helmholtz Center for Ocean Research Kiel have found that considerable quantities of the greenhouse gas methane escape uncontrolled into the water from abandoned oil and gas wells in the North Sea. On the basis of investigations directly on the seafloor it was possible to determine the amount of escaping gas.

Rivian CEO teases R1T’s flood wading abilities in new video

Teslarati

Recently, Rivian CEO RJ Scaringe shared a video of the all-electric R1T pickup taking a dip into deep waters, seemingly testing the truck’s ability to travel through floods. According to Rivian, the R1T’s wading depth is 3ft+, though the video suggests that the test involved shallower waters. Our engineers going for a quick dip!

MIT Researchers Elucidate Model for Escape of Underground Methane in Frozen Regions; Current Rate of Escape May be Much Faster Than Earlier Believed

Green Car Congress

gas hydrate accumulations in ocean sediments and permafrost—escapes. Their findings, published online 29 August in the AGU Journal of Geophysical Research , also suggest that methane trapped under the ocean may already be escaping through vents in the sea floor at a much faster rate than previously believed.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
