Stephan:   One of the most extraordinary aspects of this election, and it gets almost no discussion, is the fact that uniquely in the developed world we have a major party -- the Republicans -- who deny the existence of climate change. As this report points out only Senator Rubio, of all the party's Presidential candidates, acknowledges climate change is real. And he has so many qualifiers it's hard to know what he means. This willful ignorance ought to disqualify all Republican candidates from office. The fact that it does not, and that something north of 40 per cent of Americans also believe climate change either does not exist, or is not the result of human activity, is why we are not going to be prepared as a country for what is coming. We should be upgrading infrastructure including incorporating climate change in our planning. We we build now is what we will have. Century old infrastructure, such as we have in most of the country, is simply going to break down. Look at the report I just ran about how many cities in Pennsylvania have more lead in their water than Flint, Michigan. The infrastructure is breaking down anyway, climate change will just accelerate the process.
