Fighting global warming

California is keeping its reputation as a cutting-edge state in working to reduce global warming. The Air Resources Board yesterday approved a regulation to minimize the amount of carbon in fuels. The move will take time, of course, but calling for a 10 percent reduction in the carbon intensity of fuels by 2020 is a step in the right direction. Changing people's habits, and especially changing industry habits, will take time and patience, but every step forward brings us closer to the goal of preserving a livable environment for ourselves and our children. Now let's hope that other juriscidtions will follow California's lead and move ahead on this issue.
