While diplomats in Egypt were negotiating the #COP27 agreement last month to help poor nations cope with the crippling impact of a warmer planet, one of the biggest US climate disasters in recent years was unfolding in a rural corner of #Pennsylvania: 1/11 bloomberg.com/news/articles/…

A leak from a 1 5/8-inch vent on a natural gas storage well operated by @EquitransMid was discovered on Nov. 6 and lasted for 13 days, during which more than 1 billion cubic feet of the fossil fuel escaped. 2/11

Mountains of garbage near #SouthAsia megacities are contributing to some of the world’s strongest and most persistent #methane clouds observed by satellite, highlighting a major challenge in the global climate fight. A 🧵 on my latest for @climate

Methane leaks from ships using liquefied natural gas as fuel make most of the vessels dirtier than ones using diesel or heavy fuel oil, a new analysis shows.

One of the surprising takeaways revealed by satellites tracking the world's worst methane emissions is just how avoidable so many of them are.

A 🧵 about one of the world's most isolated climate disasters and what can be done about it: bloomberg.com/news/articles/… In western Turkmenistan, scientists have found 29 pieces of oil and gas equipment spewing so much methane that by one measure the climate impact is roughly on par with the annual emissions from all the cars in Alabama. The state has about 4.7 million light duty vehicles. 1/11

I've been using satellites to report on powerful, invisible greenhouse gases from some of the world's biggest polluters for @business and @climate and I have some thoughts🧵. Image courtesy of @Kayrros. 1/15 All greenhouse gases are bad because they trap heat in the atmosphere, but methane, which is the main component of natural gas, is especially nasty. If released without being burned, it has ~80 times the warming impact of CO2 in the short term.
