A widely held opinion is that dangerous climate change or interference has not been defined and cannot be defined by science.

This is actually of course not the case.

Danger is defined and quantified by the IPCC endorsed simple precautionary formula of
    ​RISK = PROBABILITY​ X Magnitude (of consequence or effect)

Some say that only society as a whole can define climate danger. That is not so either, but the resources below could help you do so.  ​​
