71. Many feedbacks are those we can't predict

Suddenly new microorganisms - a type of phytoplankton I believe off the top of my head, is multiplying like crazy in the arctic simply because the sea ice melts away to a certain degree in the summer. These phytoplankton respirate methane (exhale), love, of course, to sunbathe, and add to our problems climate-wise.

Another feedback, also mostly unanticipated, is that with the thawing/melting of the tundras and glaciers in Greenland, Canada, Russian Fed/Eurasia we're seeing more methane vents uncovered which were previously covered by surface ice. Again, a problem we didn't need with GHG.

Anther feedback - the CO2 levels in the atmosphere are sufficiently high enough so that the oceans are up-taking more than their share of it and it is dropping the pH of said oceans, thereby dangerously affecting the development of carbonaceous (calcium carbonate if memory serves) shells for various organisms as well as the formation and stability of the coral reefs.

Are these the type of feedbacks you're asking about? Feedbacks...feedbacks...negative or positive? Who knows?
