BTW I don't think many people were actually predicting 6 degrees so this is a bit academic. 6 degree rise sounds more like the IPCC's discredit "business as usual" RCP8.5 scenario. Most models predict a linear-ish trend of about 0.25C per decade, as you'd expect given their underlying premise that warming is all driven by CO2 and CO2 increases more or less linearly:

the predictions weren't based on a "perfectly understood relationship", but yeah, they're assuming we didn't do anything, and we did stuff, in order to reduce that number, and succeeded
so what's off base?
I pull this part out because it's key to so many of the disputes and is why climatology is such an incredibly divisive field compared to others. People who call themselves scientists should not be making high confidence predictions to the public or politicians when they don't perfectly understand the underlying relationships. They also shouldn't be making unfalsifiable predictions that rely on vague claims. This is what destroys trust in science.
For the rest I can only repeat what was already said. In reality nothing has been done. Look at the CO2 line and then mark on the various international summits, treaties, etc. They aren't visible. Nothing changed.
that is an interesting opinion, but it doesn't seem to make a lot of sense, considering nobody perfectly understands the underlying relationships of any of our science, with quantum physics still a work in progress
perhaps that is why trust in science remains, despite any nihilistic claims to the contrary
> Look at the CO2 line and then mark on the various international summits, treaties, etc. They aren't visible. Nothing changed.
it would be farcical to suggest that an international summit would somehow immediately decrease CO2 levels, and to thus treat the absence of such a ridiculous and nongradual change as evidence that there was no change
is that indeed what you're suggesting?
