Should we Seed the Oceans, to Reverse Runaway CO2 Rates?

We live on a wonderfully complex planet.

Global Plankton Blooms

The World contains the systems and feedback cycles to bring things back into balance — given enough time. (like millenniums)

The great plankton blooms of the Oceans is one such cycle, that can potentially capture more carbon than all the forests of the world; while at the same time providing the basis of the food chain, in the world’s greatest food basket.  Plankton, not eaten, are destined to become sediment rock, at the bottom of the sea (taking all that harmful CO2 with them).

Problem is, plankton blooms, have been fading, by as much as 30% due to rising Ocean temperatures. IPCC estimates that “80% of the heat that is being trapped by greenhouse gases is absorbed by the ocean.”

Humans have the know-how to “kick start” those Plankton Blooms back to their previous splendor —

Question is:  Do we dare to use the Earth as a giant Test Tube?

Climate “Clearly Out of Balance” (American Geophysical Union)

Cross-posted from THE ENVIRONMENTALIST

The American Geophysical Union (AGU) has updated its policy on climate change with the pronouncement that changes to the Earth’s climate system are “not natural.”

The Earth’s climate is now clearly out of balance and is warming. Many components of the climate system-including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons-are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century.
