this could mean the landmark paris climate agreement – which seeks to limit global warming to 2 degrees celsius (3.6 degrees fahrenheit) above pre-industrial levels – may not be enough to ward off catastrophe.

paris agreement:160
a 2018 published study points at a threshold at which temperatures could rise to 4 or 5 degrees compared to the pre-industrial levels, through self-reinforcing feedbacks in the climate system, suggesting this threshold is below the 2-degree temperature target, agreed upon by the paris climate deal.
