1) Only recently have people been able to globally collaborate using internet, and satellites. This is only about 50 years young, so in reality, a lot of people are "connecting the dots" but then the question is what if we had these stuff for the past 2000 years? Would the same conclusions be drawn?
.
We do have this data from tree rings, the world only started heating up at such a dramatic rate, a rate never seen before in human times, over the last 20 years.
If we were to stop using our cars, slow down industrialisation and take all measures required to slow down the process then the global economy would collapse on an unimaginable scale which is why you have various corrupt politicians and large corporations trying to discredit climate change.
The fact you ask who the experts are just makes me wonder if you've actually looked into the issue at all. It's not some guy with a PHD, it thousands of groups, institutions, universities and governments from across the globe who have all come to the same conclusion. It's generally just China and the US, the world’s two major polluters that are throwing up doubt (and I mean doubt, not counter-evidence)
Here is the website for our government's weather service funded by the ministry of defence; they have lots of research and data on there
The arguement against climate change is weaker than that against evolution, and it's odd how it seems to be the same bunch of conservative republicans that are questioning new research
The money argument is mute. There is money to be made on both camps. You don't think Al Gore has gotten buckets of money for his lectures? So the "they are payed off by big companies" argument doesn't hold ground unless you can actually prove that someone has been payed off.
