Tesla is fast

It's even older than that - it dates from the construction of the first railways in England. It wasn't any kind of science-based opinion, even then.

But people with more sense than you - which would be a bout 95% of the population - have enough sense to winnow through the opinions, and sort out the ones that are likely to be impartial and reliable. Your own capacity to collect and process information is extremely limited - as evidence by the truly moronic opinions you post here. You need a minder, but are much to much of an offensive creep to get the help you clearly need.

Except that they didn't. It was claimed by a few when the first railroads were set up around 1830. The trains rapidly got fast enough to prove that it was total nonsense, as had been obvious to better informed anyway.

But you are one of the most ill-informed people posting stuff here. You'd be wise to find a more reliable source of information, but you are clearly ill-equipped to do that.

The IPCC is a bunch of climate experts, selected for their expertise on climate. That means that thye have published useful scientific papers on the subject, designed to create a coherent - which is to say - self-consistent body of knowledge on that subject. They are not asked for their opinion on the correct reaction to Russia's invasion of the Ukraine and would be relucant to give one because they haven't specialised in that particular area.

Who cares who you would trust? You clearly can't be bothered to think for yourself, and latch onto the first idea that lodges in your head.

Clearly not. The IPCC is a group of experts on climate science. They exist to advise the politicians (and publish their advice so that everybody can read it).
