en CR Global Warming 22 Global Warming: a gradual increase in the overall temperature of the earth's atmosphere. Climate Change: _____increases the amount of smog in the air and causes plants to produce more pollen. Carbon Dioxide: Humans are producing far more __________ than plants and oceans can absorb. Greenhouse Effect: Energy from the sun drives the earth’s weather and climate, and heats the earth’s surface. Human Activity: Main cause of the Global Warming. Warming:There is overwhelming scientific evidence that our planet is _____ due to an increased greenhouse effect caused by humans. Atmosphere: The _______ today contains more greenhouse gas molecules. Adaptation :Adjustment or preparation of natural or human systems to a new or changing environment which moderates harm or exploits beneficial opportunities. Afforestation :Planting of new forests on lands that historically have not contained forests. Megacities: Cities with populations over 10 million. Inundation:The submergence of land by water, particularly in a coastal setting. Heat Waves: A prolonged period of excessive heat, often combined with excessive humidity. Energy Efficiency :Using less energy to provide the same service. Reforestation: Planting of forests on lands that have previously contained forests but that have been converted to some other use. Displacement:__________ of fresh or ground water by the advance of salt water due to its greater density, usually in coastal and Earnestine areas. Snowpack: A seasonal accumulation of slow-melting snow. Al Gore: Famous environment activist. Radiation: Energy transfer in the form of electromagnetic waves or particles that release energy when absorbed by an object. Oxidize: To chemically transform a substance by combining it with oxygen. Geosphere: The soils, sediments, and rock layers of the Earth's crust, both continental and beneath the ocean floors. Evaporation: The process by which water changes from a liquid to a gas or vapor. Emissions:The release of a substance into the atmosphere. Eccentricity:The extent to which the Earth's orbit around the Sun departs from a perfect circle. Effects: A process that acts to amplify or reduce direct warming or cooling _______. Sequestration: Carbon ________ is the process by which trees and plants absorb carbon dioxide, release the oxygen, and store the carbon.
