Green House Gas | Half-life in Years | Global Warming Potential (GWP 100) |
Carbon Dioxide | 1000 | 1 |
Methane | 10 | 28 |
Nitrous Oxide | 110 | 265 |
One of the most destructive yet undermentioned GHGs is nitrous oxide (N2O). This gas is 300 times more potent than carbon dioxide at warming the planet and can be found in manure and fertilizers used to grow feed crops for animals. N2O can linger in the atmosphere for over a century , and animal agriculture accounts for around 65 percent of global anthropogenic (human-induced) N2O emissions.
and emissions from traditional sources in the UK have been going down
Factory Farming is not the only place where methane is released
Sunitha Pangala, a British post-doc researcher, spent two months travelling the Amazon’s waterways
“We found a consistent story that the trees all emit a lot of methane,” she says. “In the seasonally flooded part of the Amazon, the trees become a massive chimney for pumping out methane.” Emissions from individual trees were more than 200 times higher than any previously measured anywhere.
This was not trivial. Every hectare of flooded forests was emitting several kilograms of methane each day. The on-the-ground findings doubled previous estimates of Amazon methane emissions to around 40 million tons a year. The trees were emitting as much methane as all the tundra ecosystems of the Arctic, whose permafrost contains huge amounts of the gas — a store that is expected to be released in ever-greater quantities as the region warms and its soils thaw.
