The mounting evidence around these emissions is particularly worrying because it could be a sign of a climate tipping point from which it would become difficult, if not impossible, to recover. “If we keep on doing this kind of stuff, where we are drying up lakes,” said Brothers, ”those could take over driving climate change.”
The Aral Sea paper also examined how much carbon dioxide has yet to be released from the lake, and pegged the number at about 605 million metric tons. While that makes the salt flat a ticking climate bomb, Marcé and his co-authors argue that this also means there’s an opportunity to reverse course. “We want to spotlight the fact that we have all this carbon that can be protected,” said Marce. “It’s offering a solution. Or a conversation at least.”
