The irony being that less than 50 years ago, the BBC were discussing whether a new ice age was on the way. I hope they will not be allowed to forget that, along with the long term succour they gave to sex abusers like Jimmy Savile and Rolf Harris, then sacking John Lydon (Johnny Rotten as his punk name went) for exposing Savile - meaning (shock horror), that the BBC do get it badly wrong, and most certainly can't be relied upon as a font of all knowledge and information.
With regard to climate change "deniers" or "denialists", whatever, I think the term is open to abuse, since an increase in global temperature is a hard fact. The point at discussion is precisely why, and here the narrative is entirely one way, with all other possibilities deliberately squeezed out of the conversation. Commentators with alternative theories being disallowed any platform. That's not just the BBC, it's virtually everywhere. Although GB News did have a fascinating hour long debate between two opposing sides on the matter, last Summer. That was so refreshing.
The vaccine issue is another matter entirely. I agree that at the start of the pandemic, a vaccine was essential, and that the benefits then outweighed the risks. Moreover, given the sheer mass scale of vaccinations, and the speed of development, inevitably there would be many people who were damaged and killed by it. Although the vast majority (probably > 99%), suffered no serious and/or long term side effects. But again, the term "anti vaxxer" is being badly abused and does not reflect reality, since those who are now questioning the efficacy of the vaccine, are not against ALL vaccines. Just the covid one. Personally I can't see the point in suppressing debate on the issue, especially now that covid has turned largely from tiger to pussycat. Just let people have their say. OFCOM/you tube don't need to exclude programmes discussing the vaccine.
As far as "net zero", I believe the UK are virtually the only place on Earth pursuing it with such messianic zeal and imposing absurdly tight arbitrary deadlines on its introduction.
If the advocates of climate change being 100% due to Co2 emissions, are so convinced of the scientific accuracy of their arguments, why are they seemingly so worried about other elements to the debate being allowed into the official narrative? I don't get it.
