PROFESSOR MARK JACOBSON, Stanford climate scientist. Mark Z. Jacobson is a leading, well-respected, widely published, David Letterman & Ted-X famous scientist, studying models related to wind power, solar, geothermal, hydroelectric power, wave power, black carbon, cloud and aerosol coagulation, breakup, condensation/evaporation, freezing, dissolution, chemical equilibrium, and lightning; air-sea exchange; ocean chemistry; greenhouse gas absorption; and surface processes. He has developed and applied three-dimensional atmosphere-biosphere-ocean computer models and solvers to simulate air pollution, weather, climate, and renewable energy. He has also developed roadmaps to transition countries, states, cities, and towns to 100% clean energy. He co-founded The Solutions Project, a non-profit that combines science, business, and culture to educate the public about science based 100% clean-energy. The group developed individual energy plans for each of the 50 United States, and by 2017, for 139 countries of the world. The individual state roadmaps were the primary scientific justifications for California and Hawaii laws to transition to 100% clean, renewable electricity by 2045, Vermont to transition to 75% by 2032, and New York to transition to 50% by 2030. The world and state roadmaps further served as the motivation for more than 85 cities and 150 international companies to commit to 100% clean, renewable energy.
