Individually, these authors disagree that science associating humankind's hustle and bustle is not settled science. Lindzen and Hayward questioned the chant of the world's top scientists all agreed on climate change. (Hayward 2010). In fact, two separate reputable, peer-reviewed research ventures determined that the accord on the global climate change is bigger than the IPCC primarily stated. "Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are very likely due to human activities." (n.d. 2015). "In a follow-up study directed by the Skeptical Science team of over 12,000 peer-reviewed abstracts on the subjects of 'global warming' and 'global climate change' published between 1991 and 2011. It found that of the papers taking a position on the cause of global warming, over 97% agreed that humans are causing it" (n.d., 2015). .
Notes that atmospheric temperatures are not expected to decrease for many centuries. There was an in-depth review of the scientific literature concluded that observed climate change is progressing more rapidly than previously reported by the Intergovernmental Panel on Climate Change. As a result, the Pew Center finds that the IPCC projections from its fourth assessment report in 2007 should be considered conservative in light of more observations and improved modeling techniques. (Hackett, 2014). Hackett and Cook challenge both prominent author's denial of the consensus, the settled science supporting anthropogenic global climate change. The evidence presented in the previous paragraph questions the criticism of the IPCC by Linden and Hayward. Many scientists and critics are always arguing and challenging the IPCC claim of global warming. Why is this happening? Lindzen and Hayward point of view must be considered in the environment of where their remarks distributed, their respective expert credentials on global climate change, and the conduit of the logical method.
