The news does like to sensationalize
whacky claims (e.g., those of Dr. Ehrlich). But, most didn't believe them at the time, and even the ones that sounded real were debunked within a few years. I can see where some would want to lump the IPCC into that category, but the IPCC isn't an individual or small group (it represents the majority of scientists) and instead of being debunked the models have been spot on (see graph below) for three decades. Last year I was a skeptic, but if you really
look into it, you learn it's real and needs immediate attention.
When you see news claims about places being underwater, that's generally poor understanding sensationalized by the news (e.g., sea level rise is happening, but the current
rate is one-eighth of an inch per year; so it'll take a while before gondolas are in the streets of Miami). The IPCC reports include "margins" for their accuracy, and some of the predictions have very high accuracy, and some are rather low. The problem with sensationalizing a low probability as "fact" is that often causes skepticism, but I'd say blame the news media.
...I accept we are at or near saturation for CO2 effect. More will have almost no effect....
More still does more harm. For those wanting a more detailed explanation see

The IPCC's models are spot-on ;·)
True! They've always fallen within the margin of accuracy (upper/lower lines) and they're being improved all the time (more
here). It's eerie how accurate they've been, here's the 2013 graph, the red dots are from me putting in the measured temperatures (click the image for the post)
...[global warming] You can't stop it, you cant change it.
Pfft. Ever heard of
nuclear winter? There are dozens of plan "B"s from exploding WIll's backyard into the stratosphere with nukes to making aerosols from the oceans that can have immediate and drastic cooling actions. The problem with Plan Bs are they represent
huge unknowns and as bad a global warming is we can survive it (they often don't solve all the problems either (e.g., ocean acidification)). That is they scare the bejesus out of us because global cooling is a lot harder problem to fix and the last time it happened
we almost died off. The sensible thing to do is what we are doing (eg., eliminate what we've done to cause it (e.g., net-zero on three biggest, which in order are N
2O, CH
4, and CO
2, (CFCs were even worse, but we banned those years ago to restore the ozone )).
