Recently, there has been an effort on the part of proponents of human caused global warming to convince people and the media to call climate skeptics climate deniers. This is not surprising since proponents of man made global warming can no longer make their case logically or scientifically. Last year, Dr. Walt Cunningham gave a lecture in Poland at a CFACT conference entitled Realists and the Global Warming War that discussed slander of dissenters and other topics. Dr. Cunningham was an astronaut on the Apollo 7 space mission and is a space science physicist. He is knowledgeable about climate science due to the similarities between climatology and his field.
