Natural gas, well-known for being a clean source of energy:
Leaks Can Make Natural Gas as Bad for the Climate as Coal, a Study Says
Study: Methane leaks from U.S. oil-and-gas region worse than estimates
I'm sure someone will try to tell me why increasing natural gas production is a good thing or that this is tankie propaganda in support of coal.
I mean, anyone who was convinced otherwise was delusional. We've always known that methane has a substantially higher short-term impact on GHG emissions than carbon dioxide. We've also known for years now that natural gas is notorious for leaking obscene amounts of methane (even compared to coal mining per unit energy). That hasn't stopped us from tapping and consuming more gas: in fact, total US fossil fuel electricity production has increased by 40% over the plateau in the 1970s-2000s.
In the short-term, we are incredibly, incredibly fucked. Eventually, methane decays and whatnot, but that might be too little, too late.
