I need help.
I have read the linked article 5 times and I'm still not sure what to conclude. I would like any reader to write in and comment as to what this article means and what it portends for the future. I'm not being facetious. If someone really understands this and its implications, then I would honestly like to know.
They don't come right out and say it (except once) but I think it is saying that global warming could lead to cooling. According to my read, I get five or so concrete conclusions:
1) "Changes would be felt ... around the globe"
2) "..researchers fear increased melting of the Greenland ice sheet risks disrupting the conveyor. If it stops, temperatures in northern Europe would plunge.
3) "his findings add to concerns about a 'strangling' of the Southern Ocean by greenhouse gases and global warming"
4) "Acidification of the ocean is affecting the ability of plankton -- microscopic marine plants, animals and bacteria -- to absorb carbon dioxide, reducing the ocean's ability to sink greenhouse gases to the bottom of the sea."
5) "Rintoul said that global warming was also changing wind patterns in the Antarctic region..." and "this was contributing to drought in Australia..."
So, I think the primary things to worry about are "change", decreasing temperatures, ocean "strangling", acidification leading to more gases, and drought in Australia
