What are the realistic current estimates of future warming?
• Both James Hansen of NASA—the father of greenhouse theory—and Richard Lindzen of MIT—the most renowned climatologist in the world—agree that, even if nothing is done to restrict greenhouse gases, the world will only see a global temperature increase of about 1°C in the next 50-100 years. Hansen and his colleagues “predict additional warming in the next 50 years of 0.5 ± 0.2°C, a warming rate of 0.1 ± 0.04°C per decade.
