The problem for me is that on the fringes climate activists are a death cult. The world is going to end in...., the point of no return is....; and when the date passes it is pushed back.
The Greta thing is curious. She's the perfect stooge for climate extremists. You can't question her because she is a child (we've sent lads to war younger than her), and when she is 18 in a few months and an adult, it'll be because of Aspergers. It is very cynical.
I say this as someone who works in renewable energy, specifically storage. My income relies on it. I see the issue and I see solutions. But this has become a political movement and it is divisive.
There is a direct correlation between the start of the industrial revolution and rising temperatures. But also there are anomalies in historic CO2 levels where huge increases have seen temperatures fall. It is perfectly reasonable to ask these questions and to try to understand them without being labelled a 'denier', don't like that term, has certain connotations.
The truth is, we know so much, but there is much we don't know. In the meantime, it makes sense to reduce emmisions and take steps to minimise our impact on the environment. Of course, it is perfectly sensible and desirable and we should work towards net zero by 2050 as outlined in IPCC report.
But don't politicise the issue, and ease off on the dire prophesies that often don't stand up to scrutiny.
