In the near term, oil is galloping ahead and leading our economy. We have to corral the "horse" and gradually reduce our dependence on oil and coal, in their present forms. Green-energy investment is inherently high-tech, and we could lead in the next-generation energy technologies, as we did and do now with oil and gas. All it takes is leadership!

The most effective solution is to vote! Vote the climate-change-deniers out of office. Then, for John Q. Public, it's all about energy conservation: use less, because most of what we're consuming is from fossilized carbon!

I'm working with wind, solar, and biofuels companies as well as with organizations like ACORE [American Council On Renewable Energy], Growth Energy, and AREDAY to raise public awareness and seek practical technological solutions to reduce our reliance on fossilized carbon. My book Don't Wait for the Next War will be out in October, where I will offer my prescription for America's growth, responsible development, and security.

Climate change will impact most heavily on the disadvantaged. If we don't address these impacts, as well as growing income inequalities, we are marching blindly toward major breakdowns in security, governance, and public welfare.

Climate change is, over the longer term, our greatest national security challenge. We have to do all we can to slow it down and to prepare for and ameliorate its impact.
