About 40% of methane emissions come from natural sources. But scientists are concerned that global heating is leading to more methane production in wetlands, another potential feedback loop. The rest comes from fossil fuel exploitation; livestock such as cattle; rotting waste in landfills; and rice paddies. Human-caused nitrous oxide emissions include those from overuse of fertiliser by farmers and some industrial processes.
Add on to this all the new methane seeps they’re discovering on the antarctic sea floor. Personally I think this will turn out to be a major tipping point. There is believed to be a lot of methane down there and methane, while short lived in the atmosphere, is a far more portent greenhouse gas than carbon dioxide.
Seem to get it? Um… I would think if she was getting it you would know.
