evidence: - Climate 2°C is not known to be a "point of no return", as Jonathan Franzen claims [...] UPDATE (25 August 2020): This section of the New Yorker article was edited at an unknown date, and now reads: "Some scientists and policymakers fear that we’re in danger of passing this point of no return if the global mean temperature rises by more than two degrees Celsius (maybe more, but also maybe less)." [...] There is certainly no consensus among scientists that 2.0°C (3.6°F) global warming above pre-industrial levels represents a "point of no return" for climate change.
