The president made the right decision. Carbon dioxide does warm the earth, but the earth has gone through several temperature cycles since the end of the last ice age without help from humans. The extent of future warming is still unclear. Whether increased cloud formation would counteract future warming is also unclear. If warming is mostly at night and in winter as some predict, there may be no case for action at all.
Action now is way premature.
Massachusetts has proposed to limit carbon dioxide from coal-fired power plants in the state. We hope the president's example helps persuade Gov. Paul Cellucci that there is no case at all for the state to do anything. Recipients should seek permission to reprint the article from the source listed above.
