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.
