Time for action on global warming

To the editor:The era of predictions is over. The era of consequences is here. Already we are seeing global warming wreak measurable ecological havoc as those species and ecological communities that can do so move polewards or upward and growing numbers of species are threatened with extinction. Additionally, our agricultural and forestry systems are threatened with drought and inset pest outbreaks. Meanwhile, polar and mountain ice packs melt posing the threat of elevated ocean levels. Recognizing this, nations and corporations are stake claims under the ice anticipating profits as the ice further recedes.

The time has come to act. It is unreasonable to argue any longer that climate change is not happening -- we see the consequences. Since there is over 90 percent probability that human activity is contributing, it is unreasonable to do nothing. It is equally unreasonable to argue that controlling greenhouse gas emissions is too expensive. In the long run, our inaction will cost us far more. Climate change should be viewed in at least as non-partisan a way as the threat of terrorism.

The U.S. House and Senate recently passed significant -- though different -- energy legislation. The House version established a renewable energy standard that requires utilities to obtain 15 percent of their electricity from clean, renewable energy sources (e.g. wind and solar) while the Senate -- after 20 years of inaction -- finally raised fuel economy standards. Unfortunately, each failed to include the other requirement. However, if we care about future generations, we should demand final legislation that includes both requirements.
