I appreciate the diversity of opinion re: climate change in El Reg, it keeps my climate-change believing green heart in check and reminds it to stay grounded.
That said, this piece lacks almost all journalistic credibility -- this type of piece adds nothing to the debate while sowing doubt with readers who don't bother to connect the dots. The discussion in serious scientific communities has never centered around sea-level rise as a cause of concern, but in temperature itself.
Ed take note:
Posts like these make me want to give up on my nearly 15 year history of reading el reg daily.
The second X axis included in the aforementioned chart (in the middle of the el reg article) shows 8-11C of mean temperature increase over the same period. Yes, it will take a few hundred years for giant ice reserves to melt after it's stuck in the oven, in the mean-time our planet will become a wasteland reminiscent of Mad Max's dystopia.
For context, a similar temperature rise occurred in the early triassic which turned the planet into a global desert and rendered much of the livable land masses and oceans lifeless.
