So the latest science is pretty much always running out ahead of the IPCC showing it to be underestimating the impacts.
This is a very strong claim, and it is incumbent on you to provide evidence - for example, has there been a notable increase in retractions of scientific work in the fields you mention?

(To be clear, I have no doubts that climate change is happening and it's really bad. But I do think it's important to be wary of confirmation bias in all things, and to occasionally think about whether information that challenges your current understanding of the world would reach you or not.)
Also, it may be that there aren't any significant examples where climate change is happening slower than expected. If so, that would be an interesting thing to know.
