Some New Age drivel on there, all right! We've had a change in the Jet Stream (air), a natural phenomenon, and it appears from one slightly less deranged posting that the Gulf Stream (water) has been slowing down since 2000. The Jet Stream has brought us warmer air for the past few years, meaning milder winters. It's now in a slightly different pozzie - this was explained in some detail by the Beeb's weatherman a few nights ago, but I lost concentration - but it's still all normal.
As for the damage done by dumping millions of tons of crude into the Gulf - crude is a natural substance, formed by fossil deposits going back millions of years. It's mucky, but in its untreated state it's perfectly natural and healthy. However, pouring thousands of tons of the dispersant into the Gulf might not have been such a super idea. Who knows?
We (as in humans, not Irish or Brits!) have blasted off God knows how many atomic bombs in the Pacific Ocean, rendering islands uninhabitable, we let off two monsters during WWII, we forget that centuries of sailing has seen all kinds of filth and garbage chucked overboard, much of it untreated and harmful; we poison the skies with daily tons of particulate dumped fuels which have to eventually land somewhere over land or sea; we build out artificial spits and islands into the seas (for example, Bahrain has radically altered its tiny size over the past 30+ years by scooping soil from its inland areas to build up its tiny coastline, and Dubai has built its Palm islands, thus encouraging the overgrowth of unhealthy algae, and also changing the tidal cleansing of its own beaches)... we continue to dump untreated human sewage into the seas and we have created in the past few decades the Great Pacific Gyre, a miles-wide swirl of nylon nets, plastic, plastic, and more plastic. Nobody's going to clean it up, because nobody will own up to being part of the dumping process.
We've become relatively healthier earlier and instead of great plagues sweeping away millions of us, millions more of us inhabit the Earth than a few decades back. We have taken up forms of residence in stinking, unhealthy slums or expanded over green lands with concrete and tarmac, not for once thinking that unbridled human reproduction might have a tipping point into global famine.
I wouldn't worry too much about the latest oil mess - the Torrey Canyon was the first to show the damage that could be done, the Exxon Valdez, yes, and then the tankers blown up in the Gulf by the Iraqi army during the Gulf War, which wasn't much highlighted at the time - along with the hundreds of inland oil wells which they exploded spitefully, causing heavy hydrocarbons to be released into the air for over a year.
Along with the tons of ashy, sulphuric muck circulating in the air from the volcanoes which have blown their tops (and which will continue to blow them)... it's one mucky little planet!
