A climate extravaganza got underway in Glasgow, Scotland, on Sunday. President Biden showed up. So have other world leaders and a small city's worth of diplomats, business executives and activists. It's billed as a potential turning point in the struggle to avert the worst effects of climate change, and it has a curious name: COP26.
Is it worth the hype? What might it accomplish? Here's what you need to know.
Q. What's a COP?
These climate meetings began in 1992, when countries signed a treaty promising to stabilize greenhouse gas concentrations in the atmosphere and prevent dangerous changes to the climate. Almost every year since then, the parties to this agreement have met to talk about what still needs to be done. It's called a Conference of Parties, or COP. This is the 26th such meeting. So, COP26.
