For all we know, Al Bundy's socks may be the cure for the global climate crisis.

Will the war for global warming ever be won? That depends on the amount of information we can harvest, analyze and extrapolate from. In all likelihood, the only way we will know for certain if the Earth is heading for a global warming disaster is by waiting another few thousand years and looking at history books.

But, for those not comfortable with the wait and see approach, scientists continue to plunge into one of the crucial factors thought to govern global (I’m trying not to snicker) climate change, the global carbon sink system. Roughly composed of just about every living and even more dead things, these parts of local, regional and whole-Earth ecosystems are under high scrutiny as researchers try to understand how present day climate change will further affect future climate change. The popular idea seems to be that global warming is like a snowball rolling downhill – as it rolls it picks up more snow and eventually hits something and explodes. Exploding is bad for the Earth, honest.

From the University of Colorado at Boulder comes a study supporting the theory that extended growing seasons may not be the boon for the carbon sink that many have previously thought. At least not for subalpine conifers such as the lodgepole pine, subalpine fir and Englemann spruce. It turns out these trees depend much more upon snowmelt for their summer water fix than rainfall, and in years where spring comes early due to mild winters and low snowfall, the trees actually take in less carbon dioxide over the year than when spring arrives late with heavy snow still on the ground. Up to 60% of their internal water supply from stems and needles was identified to be from spring snowmelt rather than rainfall in the fall months. We can thank our friends the hydrogen and oxygen atoms for this precise identification work.

Since around 70% of the western USA’s carbon sink is found in these subalpine forest ranges, watching the snow caps shrink yearly would definitely affect their ability to operate to capacity, should this study be accurate. Facts don’t lie; snow good, carbon dioxide bad.

On a somewhat brighter note, according to researchers at the National Oceanographic Center, Southampton, another very large and poorly understood carbon sink may be completely underestimated in present carbon cycle models. Echinoderms, which comprise a vast portion of the ocean’s calcium carbonate dump, may sequester much more carbon yearly than previously thought.

Echinoderms suck in carbon from seawater to form their skeletal systems and include such happy marine animals as star fish, sea urchins and sea cucumbers. When these animals find the end of their lifecycle, they typically sink to the ocean floor with their captured carbon and become indefinitely buried in the sediments. Some of the calcium carbonate finds its way back up the “biological carbon pump,” but probably much less than is taken down to the depths.

This could mean that the ocean is once again showing itself to be far more excellent at helping regulate global carbon levels, or it could just mean scientists still don’t really understand what’s going on in there.

If these studies only prove one thing it is that we, as a global community, race, organism and observer still have very little understanding in the way all of our ecosystems work together to regulate the Earth’s climate. It’s far too early for any sane person to jump on the “we’re melting, melting” or “Minnesota never left the ice age, what’s your problem” camps. There simply aren’t enough data to concretely support any given theory with certainty and these kinds of discoveries are shining examples of why.

There are so many 'ocean this and ocean that' theories as to make me cry for sanity. All the ones who include the ocean have so many variances in what is supposed to happen, it almost feels like they are trying hard to account for anything so they can say 'eureka' when their model follows the oceans a bit.

Recently however Al Gores primary scientist backtracked when he said the Oceans were not heating as much as his models had indicated they should, showing a greater ability to diffuse heat somehow.

The real scientists of the oceans however have said... oh crap I forget the word... Submarines move between the layers in the ocean commonly... dangit I hate forgetting a word!!! Anyways these thermal barriers keep divergent tempatured waters away from each other, and each section can grow, or shrink, with local temperature conditions.

The layers therefore can be huge for a warm spot, when weather above increases, compacting the lower, more cooler, levels down, or it can be visa versa. The current situations also help dictate changes in how these thermal levels work, since the areas with a permanent current get cycled from warm to cold, or visa-versa.

But your chemical study could be a great avenue to go down. The scientists I follow have said a lot that carbon dioxide in the past increased as a result of heating, and not the other way around.

Is the word " thermocline "?
