Al Gore has leapt to center stage with well-founded concerns about global warming. He has been gratefully successful in publicizing the fact that there is a virtual library of irrefutable evidence that carbon dioxide levels are rapidly rising in our atmosphere, that this is being caused by human beings, and that the potential impacts are catastrophic.
What's not being said is that the solution to the problem---the necessary transition to Solartopia, a world based on renewable energy---is also the key to the future of our economic well-being, and would be whether global warming was a problem or not.
In short: even without the dire disaster of climate change, a transitioning to green power is the only hope our global economy has for future prosperity.
Indeed, moving to an industrial system that runs on wind, solar, bio-fuels and other renewable sources, along with increased efficiency, including a revival of mass transit, can and will do for the global economy in the next 25 years what the computer/internet revolution has done for the last.
