You hear a lot in the media about supposed "exaggerations" of the IPCC. Did you hear much about their understatements?
Yeah, neither did we.

IPCC would never have published an implausibly high 3 meter upper limit like this, but it did not hesitate with the implausibly low 59 cm. That is because within the IPCC culture, being “alarmist” is bad and being “conservative” (i.e. underestimating the potential severity of things) is good.
