We need to start NOW. The Earth is finite and will increasingly become unable to support our worlds population. This is a much bigger deal than petty politics and jockeying for our positions in the world order. The economic impact will only become greater the longer we wait. It is time to muster available resources, American ingenuity and world alliances. Ignoring this problem now only makes the economic and humanitarian costs increasingly greater and more horrific. We need an internationally concerted effort to mitigate, diminish and/or hopefully reverse the increasingly dangerous consequences of climate change. Putting our heads in the sand and hoping it just goes away does not work. Will it be tough? YES. Will it be expensive? YES. Will it require radical shifting of government priorities and institutions? YES. Can we wait any longer to get started.? NO WE CANNOT. I love my grandchildren and do not want to see them suffer the consequences of our countries inability to act.
