If you don't want to read them, then in summary, describing the 2017 report (itself a followup to a similar 2014 report) Ars mentions:
> If you’re wondering what could have changed since the last report in 2014, the new Assessment highlights a list of areas in which our understanding has improved. That includes the evaluation of the human contribution to individual extreme weather events, higher-resolution climate models producing better simulations of things like hurricanes, and studies of ice loss in Greenland and Antarctica that have bumped the worst-case sea level rise estimates upward.[2]
In other words, the conclusions are the same as they've always been, except we underestimated how bad things are going to be. There is no reputable scientific position to take that says climate change isn't happening or that it isn't human caused. Even Chevron accepts that conclusion at this point.[3]
If you're claming that you know more than both >90% of the scientific community and the actual oil industry, then you are alone in that belief.

In case I am wrong and you truly believe this stuff, I took the time to at least disprove the source that looked most trustworthy to me in another conspiracy theory comment of yours: https://news.ycombinator.com/item?id=21084305
Entry 3508 talks about 35 degrees Celsius in May of 1892, which for Germany is freakin' hot.
Another entry calls 31 degrees Celsius in June 1818 exceptionally hot, which I would not consider exceptional at all.
