That’s unfortunately a classic case study of how #ClimateChange activism as done by #Greenpeace#WWF works exactly against its goals:
Making far-fetching and exaggerated statements about what the climate change symptoms, easily ridiculing the careful, well-sourced and conditional predictions
Turning carefully worded IPCC probabilistic statements into simplistic certainties, further ridiculing actual scientific forecasts
Rushing mitigation goals which are described as “ambitious” but in reality are simply impossible to implement in the declared schedule, ridiculing the actual mitigation scenarios as proposed by IPCC and IEA
Cherry-picking from IPCC and IEA research, praising some solutions and discrediting others (e.g. nuclear), thus further ridiculing their mitigation scenarios and presenting them in the usual “even scientists can’t agree” sauce
In short, I can only encourage you to simply ignore any popular media reporting on climate change because it’s 99% guaranteed to repeat activist narratives, thus repeating the above problems.
Instead, if you go and read the actual IPCC and IEA “net zero” scenarios, which are not only clearly written but also use balanced language and are factually correct, you will see that the actual climate science has nothing to do with the activism and most of the (valid) questions you asked are already answered by them.
