Your linked figure confirms that 2018 was cooler than things are today.

The chapter 11 temperature over view is concerning for the consequences:

  The frequency and intensity of hot extremes will continue to increase and those of cold extremes will continue to decrease, at global and continental scales and in nearly all inhabited regions with increasing global warming levels.

  This will be the case even if global warming is stabilized at 1.5°C.

  Relative to present-day conditions, changes in the intensity of extremes would be at least double at 2°C, and quadruple at 3°C of global warming, compared to changes at 1.5°C of global warming. 
...

  The frequency of hot temperature extreme events will very likely increase nonlinearly with increasing global warming, with larger percentage increases for rarer events. 
It's the harder to precisely predict potential tipping point changes that should really concern and motivate global changes to emissions.
