Don't count on forests to offset carbon emissions, study suggests

There are 8 comments on the Medincine Hat News story from Oct 26, 2010, titled Don't count on forests to offset carbon emissions, study suggests. In it, Medincine Hat News reports that:

The trees and forests long thought to be a key weapon in the fight against rising carbon emissions may not be effective in long-term efforts to combat global warming, researchers suggested Tuesday.< A new study from the University of Guelph in southern Ontario found rising carbon levels failed to stimulate faster growth in 80 per cent of the worldA ...

Apart from anything else, more forests add fuel to Nature's potential fire.

Trees have never been the answer and the rain forests have never been, "the lungs of the world."
Phytoplankton (algae) produces up to 90% of Earth's oxygen.
What's more, under normal circumstances, algae doesn't catch fire.

Phytoplankton do indeed produce lots of oxygen but they consume relatively little carbon--about a third of the global total plant uptake. Forests consume much more.

And, of course, 40% of phytoplankton have vanished over the past four decades.

Cleaning up CO2
Environmental Engineers Use Algae for Carbon Dioxide Cleanup
April 1, 2007

"Engineers have designed a simple, sustainable and natural carbon sequestration solution using algae. A team at Ohio University created a photo bioreactor that uses photosynthesis to grow algae, passing carbon dioxide over large membranes, placed vertically to save space. The carbon dioxide produced by the algae is harvested by dissolving into the surrounding water. The algae can be harvested and made into biodiesel fuel and feed for animals. A reactor with 1.25 million square meters of algae screens could be up and running by 2010."

OK, it's 2010, where are these algae screens?

Please explain?
If algae produces around 90% of Earth's O2, how much CO2 does it consume in the process?

It's hiding, because it heard that Exxon want to turn it into biofuel.
Norfie, the 'consensus' is that 40% has vanished over the last 60 SIXTY years, since 1950, apparently.
Some even blame GW for its disappearance.
It's time to get out and dig your algae pond and start growing some, that's sure to stop GW.
