The climate is such a complicated business that I wouldn't be the least surprised if maybe ten years from now it will turn out that they had it all wrong -- that all the signs and the increase in carbon dioxide and other greenhouse gasses was real enough but that the planet has self-correcting mechanisms and thinks we should have an ice age so we will have one (I anthropomorphize mercilessly). What egg on faces that sort of thing would be.
Or it may happen that technology will save us. This natural gas technology seems headed that way, and I read a bit (which may have been hype but is the sort of thing one sees more and more often) that a CO2 neutral way of getting natural gas from industrial waste is spreading and could result in unending supplies with no net greenhouse gases at all.
Or we may go as we are going and have to expend billions moving populations and adjusting, but still work through it and do fine.
Or we may go extinct.
Whether or not one believes Global Warming is real or a conspiracy or whatever, one things for sure, the seas are changing due to all the emissions - and my view is, we really dont want to poision our waters and mess with ANY parts of the foodchain:
some snippets from the following article
"Climate change is affecting the Arctic Ocean in ways that may deal a severe blow to marine life and people. The world’s oceans are becoming more acid, says a new report from the Arctic Monitoring and Assessment Programme"
As a result, marine ecosystems in the Arctic are “very likely to experience significant changes due to ocean acidification,” states the AMAP report, being discussed at a conference in Bergen, Norway April 6 to April 8.
Over the past 200 years, the average acidity of the surface of the world’s oceans has increased by about 30 per cent, scientists involved in the report said.
Ocean acidification occurs because some of carbon dioxide spewed into the atmosphere from the burning of fossil fuels dissolves in the ocean. There, carbon dioxide reacts with water to produce an acid, called carbonic acid, which causes the oceans to become more acidic.
Scientists have already determined that the surface waters of Arctic Ocean are corrosively acidic during the ice-free season
The problem? This acid eats away at the shells of clam and other tiny marine life. Increased acidity is already affecting the size and weight of shells and skeletons of urchins, sea snails and other sea creatures.
As seawater becomes more corrosive, the impact will ripple through the food chain, making it hard for fish to find food or for whales to navigate by sound.
The AMAP report says that since the marine food chain in the Arctic is relatively simple, these marine ecosystems are vulnerable to changes when external factors affect key species.
So everything, from plankton to fish, is at risk of being affected by ocean acidification directly or indirectly, its authors say.
At the same time, Arctic marine organisms are also experiencing “other large, simultaneous changes,” including climate change, harvesting, habitat degradation and pollution.
“When marine ecosystems are affected, this will also have implications for humans,” scientists say.
So conspiracies aside, some things are measurable
