Bjørn Lomborg: A Danish political scientist and author of The Skeptical Environmentalist. He accepts that global warming is happening but argues that the economic costs of drastic, short-term emission cuts outweigh the benefits, advocating instead for adaptation and investment in other global crises.
John Clauser: A 2022 Nobel Laureate in Physics who has sparked intense debate by strongly criticizing the scientific consensus, arguing that climate models are insufficient and natural processes play a much larger role.
Richard Lindzen: An emeritus professor of meteorology at MIT and a widely published atmospheric physicist. He acknowledges that co2 is a greenhouse gas but argues that the climate's sensitivity to it is lower than official models predict, and questions the severity of the crisis.
John Christy: An atmospheric scientist at the University of Alabama in Huntsville known for his work on satellite temperature measurements. He contends that climate models exaggerate the rate of tropospheric warming.Roy Spencer: A former NASA climatologist and principal research scientist. He is a prominent critic of mainstream climate models, particularly focusing on cloud feedback mechanisms, arguing that natural shifts play a far greater role in temperature changes.
Ivar Giaever: A Nobel Prize-winning physicist who has frequently challenged the "consensus" label, expressing public skepticism about the alarming rhetoric surrounding climate data.William Happer: An emeritus professor of physics at Princeton University. He argues that co2 increases are beneficial to the planet rather than harmful, and that the warming effects of increased greenhouse gases are heavily exaggerated.
Judith Curry: A climatologist and former chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. She emphasizes the inherent uncertainties in climate models and argues that the role of natural climate cycles is often downplayed.
Ian Plimer: An Australian geologist and professor emeritus. He has authored several books arguing that current climate changes are entirely normal and are driven by cyclical, natural phenomena (such as solar activity and plate tectonics) rather than human industrial activity.
Steven Koonin: A physicist and former Under Secretary for Science in the US Department of Energy. In his book Unsettled, he accepts that the globe is warming due to human activity but argues that the mainstream media and political figures overstate the severity, certainty, and immediate dangers.
