Document Summary
Goals for fixing the problem: minimize temperature increase but some warming is locked in. Temperatures will increase by 0. 5 degrees because the ocean takes time to warm. How to prevent higher co2 : flattening out co2 emissions still leads to large increases in co2 concentrations. 350 ppm: james hansen, nasa scientist and activist has won many awards. 350. org is a worldwide action group started by bill mckibben. Ways to prevent warming: take out co2 out of the atmosphere, geoengineering solutions and how to emit less co2. Alternative energy sources: renewable energy : generated from natural sources such as solar, wind , tidal, geothermal and hydroelectric. Nuclear energy as well but it is not renewable. U. s. energy sources: since 2011: oil is 35%, natural gas 28%, coal 18%, renewables 8% Facts about co2: co2 per unit energy emitted: 67% more co2 than natural gas, 30% more co2 than oil, therefore coal is a dirty fuel.
