While he acknowledged that scientists are unable to predict its consequences, Mayor Bloomberg yesterday compared the scourge of global warming to the threat of terrorism and the proliferation of weapons of mass destruction. Although it is a "long-term" fight, he said, reducing gas emissions may save the life of "everybody" on the planet, the same way that fighting terrorism and its proliferation saves lives in shorter terms.Addressing a U.N. climate change conference, the mayor also announced a new plan to reduce the use of tropical hardwoods by New York City and told delegates that the city plans to host a meeting in June of leaders from 20 major world cities to discuss ways for the largest municipalities to reduce global warming. Other participants in the conference called for a "war" against climate change, in which the United Nations would serve as a front-line combatant.
Mr. Bloomberg renewed his call, made first late last year, for taxing countries such as America that emit large amounts of carbons, which are believed to cause changes in the planet's climate. "So long as there's no penalty or cost involved in producing greenhouse gases, there will be no incentive" to meet targets set by international institutions, the mayor told the General Assembly. "For that reason, I believe the U.S. should enact a tax on carbon emissions.
