Causes, Effects and Solutions of the Global Warming Crisis

Global warming or the greenhouse effect refers to the increase in the average warming temperature of the earth’s atmosphere and oceans in recent decades. The term “global warming” is a specific case of the more general term “climate change” (which can also refer to cooling). Global warming generally implies a human influence. Some organizations use the term “anthropogenic climate change” for human-induced changes.Too many greenhouse gases in the earth’s atmosphere will increase the greenhouse effect. The most dangerous aspects of the continuing dramatic climatic change is the effects of feedback loops (amplified change). Examples of the feedback loops are Ice/snow, as the earth warms, the levels of ice and snow decrease. This decrease leads to higher temperatures on the surface, leading to more warming. As the earth warms, the amount of water vapor in the atmosphere goes up which is the most powerful greenhouse gas in existence.The year 2005 was the warmest year in over a century, according to NASA scientists studying temperature data from around the world. The Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report projects that the Earth's average surface temperature will increase between 2.5° and 10.4°F (1.4°-5.8°C) between 1990 and 2100 if no major efforts are undertaken to reduce the emissions of greenhouse gases (the "business-as-usual" scenario). This is significantly higher than what the Panel predicted in 1995 (1.8°-6.3°F, or 1.0°-3.5°C), mostly because scientists expect a reduced cooling effect from tiny particles (aerosols) in the atmosphere.
