Natural, not anthropogenic (human caused) climate change has always happened and is happening.
Meterorologist Roy W. Spencer, (co-developer of the NASA satellite method for precise monitoring of global temperatures) warns of, “Global warming hysteria leading to bad science, pandering politicians and misguided policies that hurt the poor,” (Climate Confusion Encounter books, 2008.)
Tim Ball in Deliberate Corruption of Climate Science, writes, “Some call the human-caused global warming theme a hoax, but ... a hoax is a humorous deception ... There is nothing humorous about the corruption of climate science.’’ German Physicist and Meterologist Klaus-Eckart Plus confessed: ” I [previously] simply parroted what the IPCC told us. One day I started checking facts and data ... I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts.“
Lawrence Soloman, a committed environmentalist himself, in his book, ”The Deniers,” (Richard Vigilante Books, 2008) provides facts, not opinion. Read these facts as 32 world reknown climate scientists are presented, each show that Anthropogenic Global Climate Change might be happening, but in my particular discipline science does not back it up.
