In short, panic
There’s a lot to glean from this graph, but here’s the takeaway: We’ve already crossed over into moderate risk on the first three RFCS. Pushing temperatures up 2 degrees Celsius over preindustrial levels — the target at which the world claims to want to stop warming — puts us at high risk on the first three and moderate risk on the last two. That is the best-case scenario.
Three degrees over preindustrial levels, where we are very likely headed this century, puts us at high risk across the board, very high for those uniquely threatened systems. Five degrees, which is entirely possible, puts basically every human and ecological system at high to very high risk.
We are already in danger, there’s more danger to come, and the best we can hope for is to slow and stop the process before the dangers are catastrophic. That’s the shape of things.
