I remember science bloggers complaining that the recent IPCC report didn’t predict enough doom and gloom to get political results.

They may well be right, but they weren’t saying that they had reason to believe the IPCC had understated the influence carbon dioxide, methane, or some other gas has on the climate, or that predicted emissions where wrong, etc. They were complaining that the report didn’t have enough scare mongering. That’s not science, and it could easily lead to a big overcorrection in a few years.

Not really once you realize how much of the fearmongering is completely baseless.

There is literally no scientifically demonstrated consequence of climate change that we don't know how to deal with today let alone in 10-40-100 years from now.
