Not exact matches

As the food decomposes it releases methane, a powerful greenhouse gas, subsequently contributing to climate change.

It produces less carbon dioxide emissions than coal for electricity or gasoline and diesel for fuel, but even a small amount of natural gas release — which is essentially methane — packs a greenhouse gas punch about 30 times more powerful than the same amount of carbon dioxide.

The Aliso Canyon natural gas well blowout, first reported on Oct. 23, 2015, released over 100,000 tons of the powerful greenhouse gas methane before the well was sealed on Feb. 11, according to the first study of the accident published today in the journal Science.

Most end up in landfills, where they decompose and release methane, a powerful heat - trapping greenhouse gas.

The release of this trapped methane is a potential major outcome of a rise in temperature; it is thought that this is a main factor in the global warming of 6 °C that happened during the end - Permian extinction as methane is much more powerful as a greenhouse gas than carbon dioxide (despite its atmospheric lifetime of around 12 years, it has a global warming potential of 72 over 20 years and 25 over 100 years).

Climate change is driven by human activity — chiefly the combustion of fossil fuels and changes in land use — and forests and other natural ecosystems play a powerful role in both soaking up the greenhouse gases released by human economic activity and at the same time sheltering many of the other 10 million or so species that share the planet.

As this organic matter thaws it decays, releasing carbon dioxide and methane, another powerful greenhouse gas, and insulating the planet still further.

Humans burning fossil fuels (coal, oil and natural gas) release carbon dioxide, a powerful greenhouse gas.

Released from the pressures of the ocean depths, methane hydrate expands to create huge volumes of methane gas, one of the most powerful of the greenhouse gases.

The storm would likely not have been as big and powerful as it was, nor would it have likely struck land where it did were it not for the extra greenhouse gasses released by humans over the last century and a half or so.

«The increased open water lowers the average albedo [reflectivity] of the planet, accelerating global warming; and we are also finding the open water causing seabed permafrost to melt, releasing large amounts of methane, a powerful greenhouse gas, to the atmosphere.»

We also underestimated the potential importance of strong feedbacks, such as the thawing of the permafrost to release methane, a powerful greenhouse gas, as well as tipping points beyond which some changes in the climate may become effectively irreversible.»

When permafrost melts it can also release methane, another powerful greenhouse gas.
