One of the oft-repeated mantras of the global warming crowd is that there is no longer any debate in the scientific community about the threat of global warming. That is just not true. While there are many scientists who firmly believe global warming is real and it is a threat, there are many other scientists who have serious reservations about that judgment. One who sticks out in the debate on global warming is Danish statistician Bjorn Lomborg. Five years ago, Lomborg who views himself as an environmentalist, ignited a firestorm of controversy with his book The Skeptical Environmentalist. In it, Lomborg pointed out, as he has continued to explain since, "that actually a lot of the things we are doing to the environment are making it better". On global warming, he told the online site TechCentralStation; "Global warming is an important issue and one which we should address. But there is no sense of proportion either in environmental terms, or indeed in terms of the other issues facing the world." According to Lomborg, millions die each year from lack of clean drinking water and proper sanitation and indoor air pollution kills millions more, but a warmer world poses no such threat. "One of the top climate change economists has modelled—and several papers that came out a couple of weeks ago essentially point out -that climate change will probably mean fewer deaths, not more deaths. It is estimated that climate change by about 2050 will mean about 800,000 fewer deaths. " Another critic of the standard model of global warming is MIT professor of meteorology Richard S. Lindzen. A giant in climate science, Lindzen has published literally hundreds of scientific papers. In an op-ed in the Wall Street Journal in 2001, writing about a National Academy of Sciences report on climate change in which he participated, Lindzen noted: "We are quite confident(1)that global mean temperature is about 0. 5 degrees Celsius higher than it was a century ago;(2)that atmospheric levels of carbon dioxide have risen over the past two centuries; and(3)that carbon dioxide is a greenhouse gas whose increase is likely to warm the earth(one of many, the most important being water vapor and clouds). But—and I cannot stress this enough we are not in a position to confidently attribute past climate change to carbon dioxide or to forecast what the climate will be in the future. That is to say, contrary to media impressions, agreement with the three basic statements tells us almost nothing relevant to policy discussions. " The top climate change economist mentioned in the third paragraph______.
