The sooner we switch away from carbon-based fuel and start relying on renewable energy sources available in the United States, the sooner we will grow our economy by creating the millions of new jobs that will come from retrofitting homes and businesses, building smart grids, renewable energy systems and planting trees and all the rest. We need to create a lot of jobs that can't be outsourced.

The rule of reason is the true sovereign in the American system.

We're still putting 110 million tons of man-made global pollution into the air every single day as if the sky is an open sewer. More than 90% of the extra heat energy is going into the oceans, and that's why superstorm Sandy was so much more destructive, that's why the ice is melting more rapidly, that's why the water cycle is being disrupted and we get a lot more water vapor coming from the oceans into the sky, and that's why we get these enormous downpours and big floods. They happen all the time. Every night on the TV news is like a nature hike through the Book of Revelation.

The more deeply I search for the roots of the global environmental crisis, the more I am convinced that it is an outer manifestation of an inner crisis that is, for lack of a better word, spiritual... what other word describes the collection of values and assumptions that determine our basic understanding of how we fit into the universe?

[T]he scientific enterprise will never be completely free of mistakes. What is important is that the overwhelming consensus on global warming remains unchanged.
