we are now facing a certainty of at least 2 deg warming over the average temperature from the previous 120 years. (pre 1975)
with a probability we'll exceed 3 deg rise by 2100 or sooner.
the effects of the current rise to 1.5deg is looking very worrying. given that each point of a deg results in exponential changes in volatility and extremes we might be seeing 60deg max temperatures by 2100.
