The findings, from two separate research groups... say the process of carbon sequestration is already underway. Even so, the new carbon sink is unlikely to make a significant dent in the huge amounts of CO2 pumped into the atmosphere by industrial activities...
Phytoplankton produce chlorophyll to obtain energy from the sun and assimilate CO2, and so increased phytoplankton productivity would remove more carbon from the atmosphere...
From one year to the next, the phytoplankton grew more in areas where the ice had disappeared: less ice meant more open water for longer, allowing the plankton to soak up more energy from the Sun. In some areas, production was boosted more than three-fold...
If the Arctic became completely ice-free and phytoplankton productivity levels were maintained, Arrigo and his colleagues calculated that the new carbon sink could in theory absorb an extra 160 million tonnes of carbon each year...
What is clear is that the impacts of the melting Arctic ice are complex and will continue to unfold as temperatures rise. Less ice cover may mean more phytoplankton, but it also means a darker sea surface, which will reflect less solar energy back out into space...
fish that live in open water would be favoured over the predators that rely on ice - ringed seals and polar bears for example - that dominate today.

Well, this is interesting. It’s another piece of evidence to show that we don’t know exactly all of the processes underway. We should be willing to say that we don’t fully understand all of this. And Al Gore should also be willing to say that HE doesn’t know everything there is to know about this whole global warming process.
Does that mean we can fire up the BBQ again?
all I get (so far) is “No Such Thread”. :’)
Compound speculation is NOT SCIENCE!!!!!
If, If, If, If, THEN WERE ALL GONNA DIE!!!!
Ditto! You always have good stuff, so was wondering if I have a computer problem, or ISP problem, or the link is down?
Never forget that global warming is not a science, it is not a political position. Global warming is a religion....people who believe in its existence can never be convinced otherwise.
The “huge amounts” of carbon dioxide pumped into the air from industrial activity of ALL kinds, pale in comparison to the amount that comes naturally from decomposing plant matter and exhaled from the warming sea water beneath the tropic sun. Carbon dioxide is readily reabsorbed into water everywhere, where it provides a very important link in the growth of aquatic plant life, from sea grass to plankton, to floating seaweed. Carbon dioxide is CONSTANTLY being sequestered by the activity of photosynthesis, releasing oxygen into the atmosphere, at a pretty constant level. It took billions of years for oxygen to reach the levels (roughly 20%) it now stands at, and in fact, when carbon dioxide was even MORE plentiful than it now is, was perhaps even higher at one time.
Simply put, we the people, NEED oxygen. And without plentiful carbon dioxide, it would never be formed. Know this and know it for a certainty: Carbon dioxide is plant food. Without it, plants wither and die. It is our OBLIGATION to increase carbon dioxide to the degree we are able, to aid our plant life on this planet to grow and extend to its maximum limit.
There is no climate “cure”, because there is no climate “disease”. We rely on carbon-based fuel, and the excess carbon dioxide merely goes into accelerated and extended plant growth. So long as we encourage plant growth at every juncture, by cultivation and land management, the content of carbon dioxide shall never rise above about 0.05% concentration in the atmosphere.
Plants require carbon dioxide to conduct photosynthesis, and greenhouses may enrich their atmospheres with additional CO2 to boost plant growth, since its low present-day atmosphere concentration is just above the “suffocation” level for green plants. A photosynthesis-related drop in carbon dioxide concentration in a greenhouse compartment can kill green plants.
To global warming fanatics, global warming is real and capitalism is the problem. Never mind that the global temperature has only risen a year in the last 100 years. Never mind the fact that temperature records only go back so far. Never let the facts get in the way of a global warming argument
It almost sounds like it was designed that way.
We’re talking about the “Puppies Die” story, right? :’)
...and just for kicks, melt some ice on the grille.
Frankly my dear, I don.t give a damn.
If's, maybe's, could's, possibly's. They need to rename this piece of enviro-alarmist trash to The New Junk Scientist. Find data that shows the possibility of a short term trend, then extend that trend to infinity, then shout how we're all gonna die. Envirowacko "science" at its very best.
This is an example of "pier" reviewed science publishing. All it's good for is dropping off a short pier. Oh, wait! That would cause more water pollution. Nevermind.
