QUES: Von Neumann's team performed the world's first numerical weather forecasts on the ENIAC computer; von Neumann published the paper Numerical Integration of the Barotropic Vorticity Equation in 1950. Von Neumann's interest in weather systems and meteorological prediction led him to propose manipulating the environment by spreading colorants on the polar ice caps to enhance absorption of solar radiation (by reducing the albedo). thereby inducing global warming. Noting that the Earth was only 6 °F (3.3 °C) colder during the last glacial period, he noted that the burning of coal and oil "a general warming of the Earth by about one degree Fahrenheit."
