Just a few examples of the societal issues the world will have to deal with in an overshoot scenario show that that path will be fraught with huge and unpredictable problems, as well as inequalities.
Not to mention the risk of triggering tipping points.
If it weren't for the fossil fuel lobby we would have come to the conclusion long ago that quitting the burning of stuff is the way to go, and the sooner the better.
"In simple English, “overshoot” means to go past or beyond a limit. But, in climate science, the term implies both a failure to meet a target – as well as subsequent action to correct that failure."
But at least one scientist "warned that the concept of returning temperatures back down to 1.5C after an overshoot is “not a political project yet”."
Because the path is littered with technical, social, and political mines.
"Overshoot pathways are those which exceed the 1.5C limit – before being brought back down again through techniques that remove carbon from the atmosphere.
The conference explored both the feasibility of overshoot pathways and the legal frameworks that could help deliver them.
Researchers also discussed the potential consequences of a potential rise – and then fall – of global temperatures on climate action, society and the Earth’s climate systems."
Overshoot
"Temperatures should stop rising once net zero is reached. But the world has been so slow to cut emissions that by then, the average global temperature is set to be higher than 1.5C. So returning to a 1.5C rise would require not just huge emission cuts but the removal of vast amounts of carbon. In other words, we would be leaving the world of net zero and entering an age of net negative emissions goals.
The technical challenges alone would be large."

The shine is coming off.
Fast enough?
