Greenhouse gases (CO_2 methane, NO_2) will be reduced and result in atmospheric cooling The current CO_2 in the atmosphere will remain for some time and then become reduced, allowing for atmospheric cooling Global temperatures will continue to rise, by approximately 2 degree C Atmospheric temperatures will cool rapidly, resulting in rapid recovery from global warming Answers B and C Building a seawall to protect a city against sea level rise would be classed as Adaptation Mitigation Both mitigation and adaptation Geoengineering strategies such as reforestation (in order to remove CO2 from the atmosphere through increased photosynthesis) would be considered Adaptation Mitigation Both mitigation and adaptation Reducing emission of greenhouse gases is an example of Adaptation Mitigation Both mitigation and adaptation Moving to a different location that has more manageable climate conditions would be classed as Adaptation Mitigation Both mitigation and adaptation Oil and gas form from: accumulation of inorganic material, such as clay particles in shale oxidation of organic material at the surface heating of rocks to metamorphic temperatures (at least 400 degree C) heating and breakdown of long hydrocarbon chains into smaller molecules What is the starting material for coal? limestone with abundant shells sandstone formed in certain environments plants black shale all of these Which of the following is an advantage of wind power? it can be used nearly everywhere because all areas are windy enough wind power is renewable and can be used in remote locations variable winds allow variable amounts of power generation wind turbines are attractive in scenic places, like off Cape Cod it already provides a large percentage of the world's power requirements
