No one is (or at least no one should be) arguing the worlds temperature is not increasing. Even @KHHville the scientist you just cited, Richard Lindzen, as being eminently qualified openly admits that. despite being on the fringe and despite aligning with known think tanks and getting caught fudging the numbers.
So, to put it in perspective, to find someone who claims the planet has not been warming you have to go even further than the already fringe scientists and find people outside of science altogether or full blown activists who just don’t care about facts.
Fringe scientists like Linzden play with the variables, claim natural warming is larger than it is, hence anthropogenic is smaller than claimed and play up the uncertainty of predicting the future. They do not claim anthropogenic warming is not a thing at all, because they know full well such a claim is stupid.
Talking of stupid, Trump just did his yearly global warming troll tweet. I swear if global warming was the only topic which mattered, I’d be throwing him under the bus twice as fast as anyone else.
