The Globe «s Jeffrey Simpson offers Canadian politicians plaudits for the following good deeds: Ed Stelmach's decision to fund research into carbon capture and storage; Dalton McGuinty's decision to protect the boreal forest (because «untouched forests are wonderful carbon sinks») and to sign on to the Western Climate Initiative; Stephen Harper for agreeing to pour money into Ontario infrastructure; and the premiers for finally agreeing «that within one sovereign country, there ought to be as few obstacles to the movement of people and capital as possible.»

The approach ranked as the study's least viable strategy, in part because less than a quarter of the algae could be expected to eventually sink to the bottom of the ocean, which would be the only way that carbon would be sequestered for a long period of time.

As a result, roughly 50 percent of the captured carbon sinks through the so - called twilight zone there — perhaps because it is heavier and therefore descends faster — compared with just 20 percent in the balmier waters off Hawaii, which support smaller life - forms, researchers report this week in Science.

Because the algae take in three times the CO2 to produce a single ton of ethylene, the process acts as a carbon sink.

And because mangrove forests are carbon sinks, «mangroves also emit carbon dioxide to the atmosphere, and naturally, the balance is positive — unless they are heavily degraded, such as from aquaculture, and then they will become carbon emitters.»

That's unexpected because carbon dioxide is increasing so fast in the atmosphere that you would expect the sink to increase as well,» says Le Quéré.

Because a large flux of CO2 is constantly being assimilated into the world as forests via photosynthesis, cutting off its return pathway to the atmosphere forms an effective carbon sink....

The Amazon forest acts as a carbon sink, because trees suck the greenhouse gas CO2 out of the atmosphere as they grow, during photosynthesis, converting this to plant matter including bark, wood and roots.

Because these lands play such a vital role as carbon sinks, it's no surprise that their destruction is partly responsible for the emissions from land use changes that add up to nearly 18 percent of the total global warming effect.

Restoring degraded forests has come to be recognized as perhaps just as critical to climate efforts as stopping deforestation, because of how reforestation efforts can enhance forests» role as a carbon sink.
