Peter T. Doran is a professor at Louisiana state university teaching in geology and geophysics. He is shown to show his interests in polar regions like global warming in the Antarctic which brought upon his strong belief that humans do cause climate change. He has published many studies to examine the contrast in beliefs and quotes a fellow study the created by another scientist, Naomi Oreskes. He also contributed to the paper “Consensus on consensus: a synthesis of consensus estimates on human-caused global warming” with other scientists like John Cook on the belief that 90-100% of climate change is caused by humans.
