So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different. Historical comparisons.

Climate change is here, and nowhere is this more immediately apparent than in our ocean. It makes sense that our ocean would bear the most immediate impacts because it is on the front line of actually absorbing and storing the carbon that causes climate change to begin with.
