In an article about Earth approaching the climate tipping point I found a link to another story about the CO2 content in the Southern Ocean that surrounds the Antarctic. So far the Southern Ocean has done most of the work of keeping so much of the carbon dioxide we release out of our atmosphere, but there is only so much it can take in as a carbon sink. It efficiency is lessening to the point where it will not hold much more, thus more of the carbon dioxide we release is staying the atmosphere.
Does this make you think more about your energy use?
I have been conscious of my energy use for years, but this really does make me think that we really need to be more committed to lessening our carbon dioxide release.
