We know as much about the effects of geo-engineering as the impact of green house gasses and you are prepared to make wide ranging, expensive and potentially dangerous decisions in stopping projected problems that arises from that.
Dangerous decisions? Who am I to make any decisions about it at all? But
think about it, Wolfe - so you add sulphur dioxide to combat the greenhouse gases - when do you stop doing this? Ever? And what will the effects be? We don't know, except that we can wave goodbye to blue skies forever. We continue pouring sulphur and CO
2 into the atmosphere in perpetuity, and who knows? It might all even out. And it might not.
As to using Wiki as a source, I actually googled "current sea level rise" and got 3,400,000 results. I just picked the first one, and qualified that with "for a start". I don't actually see any problem with that. Anyone can google it and find that the sea level has, as far as we can tell, risen more than expected over the past decade or so. It might have nothing to do with the Ross Shelf and the melting of Arctic sea ice. On the other hand, it probably does.
Back to Sci-fi. George Turner wrote a book called
The Sea in Summer, set in Melbourne after the sea level has risen. This book sold nearly a million copies and won the 1988 Arthur C Clarke award, nevertheless it is out of print and only used editions are now available. I highly recommend it to sci-fi lovers and people who can't imagine what a sea level rise of a mere metre would mean to most of us Australians who tend to live on the coast (luckily I don't). But you can't get it from a library and to me this begs the question of why not? I'm not normally a conspiracy theorist, but the general unavailability of this award-winning book is mysterious.
Anyway, I'm not particularly interested in winning over climate change skeptics - time will do that (and less time than you may think). I just think it's sad that humanity's hubris is going to lead to a catastrophic world, and I feel very glad that I ensured my kids had martial arts training. Because when all our systems DO break down, the world will become an extremely dangerous place, in their lifetimes.
