Last sentence in the Abstract:

"We estimate a collapse of the AMOC to occur around mid-century under the current scenario of future emissions."

Further in the paper

"The mean of the bootstrapped estimates of the tipping time is 〈tc〉 = 2050, and the 95% confidence interval is 2025–2095."

Whoof. Those are some spooky error bars.

Especially since almost every "long term" problem seems to be happening in the much shorter term than was originally predicted. Not great!

Climate change was sometimes dismissed (or reduced) by saying that’s it an issue for our grandchildren. With those error bars (NOW to +40 years), the immediate nature of the problem and the required response should hit home. Given recent heatwaves, I think nature is starting to hit us with the clue stick. I hope the important people are listening.
