We've known for decades the world is warming, so it shouldn't come as a shock when some records get broken along the way. But what has set off alarm bells among the scientists who study our changing climate recently is just how fast it's happening, in ways that don't match up with any previous models. From ocean temperature to sea ice, forest fires to heat domes and the world's daily average temperature record being broken at least twice just this week, warning lights are flashing.

Is this truly the tipping point for our climate crisis? What does that even mean in this context? And as the bad news rolls in, is there another tipping point coming—a moment in which we collectively realize we can't survive without massive change?
