This legislation is needed for a multitude of reasons. The United Nations international climate science panel found through a study that the effects of global warming could become irreversible by the year 2030 without rapid action. The West Antarctic ice sheet could melt, raising sea levels another 4 inches. Without the ice sheet to reflect the sun's rays, oceans would absorb even more heat. That would melt more ice, worsening the heating cycle. Without rapid action, the problem will increase exponentially. Although initially it will be costly, ignoring climate change far exceeds the price tag of dealing with it.
