“How can you deny that man made global warming is real when 97 percent of climate scientists agree that it is true?”
The 97% figure from the survey comes from a whittling down of the accepted number of responses from 3,146 to 79. The 79 scientist are those that said they have recently published 50% of their papers in the area of climate change. Of these, 76 of 79 answered “risen” to questions one (96.2%). How this number is not 100% is very strange. As to question two 75 of 77 answered “yes” (97.4%). As I have shown above this response does not necessarily mean that the respondent was attributing the significant human activity to the use of fossil fuels. Additionally a “yes” response does not quantify the degree of significance that human activity has on climate change. This can range significantly from person to person.
