BUT THE OLDER THEY ARE, THE LESS THEY MAY NOTICE

VARIABLE VARIABILITY 
A historic climate election in Germany

"... The younger you are the more climate change will impact your life.
Young people also more often vote for the first time and are change allegiances faster; so partially it may be a question of time. Furthermore, younger people were already politicised because the Conservatives were hurting the internet, #article13. 
And the denigrating way they were treated then and now on climate change was a good motivation to show up and vote. The biggest campaign helpers of the Greens were the Conservatives, especially my local MEP Alex Voss representing Bonn and leading the effort for internet upload filters."

The green election statistics depicted in  this image could become a source of cognitive dissonance:

In terms of lifetime Delta T,  people in the "18-24 jahre"  bracket have experienced about four times less global warming than those in the "70 und alter" cohort, yet they appear to be about three times more concerned.

It remains to be discovered how long this Green generation gap can  be sustained should AGW  continue its sullen refusal to take off as fast as applied behavioral science.
