We have just passed the 20 year anniversary of Al Gore's An Inconvenient Truth. When he was asked recently by ABC News Chief Meteorologist and Chief Climate Correspondent Ginger Zee whether the film and its predictions on global warming hold up, Gore responded, "Unfortunately, yes." He went on to say, "The scientists were dead right on all the important elements of it and it really is insane that we are continuing to use the sky as an open sewer and we're trapping so much heat every day it's equal to the amount that would be released by 800,000 Hiroshima-class atomic bombs exploding every day on the earth." Earlier this year the Yale School of the Environment published an article titled, Overshoot: The World is Hitting Point of No Return on Climate. They stated: "With warming set to pass the critical 1.5-degree limit, scientists are warning that the world is on course to trigger tipping points that would lead to cascading consequences from the melting of ice sheets to the death of the Amazon rainforest-that could not be reversed." Returning to Crosstalk to discuss the latest response by the U.N. General Assembly to such news was Alex Newman.
