Tom Nelson caught this :
Schneider is claiming that in the 1970s “we” knew that carbon dioxide would overheat the Earth, the following image is shown: look, it says “Climatic Change” there, and that portion of a graph appears to show rising temperatures!
However, there is a big, big, big problem with using this image: It’s from a famous Newsweek article called “The Cooling World”, from April 28, 1975 (PDF here). Note that when you are allowed to see the entire graph (below), it shows plunging temperatures since the 1940s. Note that when you see the entire article, it contains a climate change “solution” that involves “melting the arctic ice cap by covering it with black soot”.
