Abandoning all loyalty to the democratic processes this nation holds dear, President Obama has made the decision that getting energy tax legislation through Congress with the approval of the American people is just too much of a pain to bother with. Instead he will have the EPA declare as early as next week that CO2 is a dangerous global warming gas and will start regulating its emissions immediately.
The Southern Ocean may be 30 years closer to a tipping point for ocean acidification than previously believed, putting sea life at risk, according to research published in this week's Proceedings of the National Academy of Science.
Analyzing seasonal changes in pH and the concentration of carbonate in the Southern Ocean, scientists from the University of New South Wales (UNSW) and CSIRO found that seasonal swings will amplify the effects of carbon dioxide emissions on ocean acidity, speeding up ocean acidification by 30 years relative to previous estimates.
The acceleration of acidification — which reduces the availability of carbonate ions used by calcifying organisms to form calcium carbonate shells — could have significant impacts on marine life. In particular, pteropods, a type of plankton that makes up an important part of the Antarctic food chain, will be challenged by increasingly acidic conditions.
Phytoplankton need two things for photosynthesis and thus their survival: energy from the sun and nutrients from the water. Phytoplankton absorb both across their cell walls.
In the process of photosynthesis, phytoplankton release oxygen into the water. Half of the world's oxygen is produced via phytoplankton photosynthesis. The other half is produced via photosynthesis on land by trees, shrubs, grasses, and other plants.

If you believe in a free market system, then you should believe in cap and trade. Cap and trade has a track record of being a highly efficient method of solving pollution problems because it employs market mechanisms.
If it is done right, cap and trade will not create new costs, it will just shift existing costs away from the American tax payer and onto those who pollute the most. (In econmists' parlance, cap and trade will eliminate the externalities of carbon pollution.) As is, all of America is paying for its high carbon life style.
We spent billions of dollars fighting wars over oil and we will continue to spend billions more. We will spend billions of dollars rebuilding cities that have been devastated by hurricanes and floods egged on by global warming. Those that are most responsible for these costs should pay them via carbon taxes, rather than having all Americans foot the bill in the form of budget deficits or higher taxes.
