Aug 6, 2018 ... Even if the Paris agreement is successfully implemented, the planet could still heat up by 5 degrees Celsius, scientists warn.

The lead authors say:

“Our study suggests that human-induced global warming of 2 degrees Celsius may trigger other Earth system processes, often called 'feedbacks,' that can drive further warming — even if we stop emitting greenhouse gases.” 

And:
“These tipping elements can potentially act like a row of dominos. Once one is pushed over, it pushes Earth toward another. It may be very difficult or impossible to stop the whole row of dominoes from tumbling over.”
