textual evidence for persuasive techniques  

scientific data:

“As presently constituted, earth's atmosphere contains only 370 parts per million (ppm) of the colorless and odorless gas we call carbon dioxide.”

appeal to logic:

“If, then, the climate models cannot correctly predict what should be relatively easy for them to correctly predict (the effect of global warming on extreme weather events), why should we believe what they say about something infinitely more complex (the effect of a rise in the air's CO2 content on mean global air temperature)?”  

scientific data:  

chart showing increase in human life span because of technological progress

emotional appeal:

speaker's reference to his grandson
