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.
I kept one for a while because I had read a book that claimed doing so helped you recognize when you are dreaming. Knowing when you are dreaming lets you have lucid dreams and control the elements of your dream. I succeeded once. For just a very brief time before I lost it and woke up. But yeah, the dreams I thought were interesting were a whole lot less so when I reread them later.
