Global Warming

Global warming is one of the most challenging environmental problems in existence today. Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. It threatens the health of the earth’s inhabitants and the world’s economies every day. With global warming come longer and more intense heat waves and storms. Along with those climate changes, come more pests which in turn can carry devastating diseases. Forestry and farming are feeling the negative impact of global warming and we’re also seeing traces of a devastated ecosystem. To prevent further damage and begin repairing the damaging effects of global warming, policies must be implemented and diligently enforced. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while long wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability. There are many misconceptions about global warming. Some believe that pollution causes global warming, but the fact is global warming is the result of burning fossil fuels, coal, and oil that release carbon dioxide. Another misconception is nuclear power causes climate change. Nuclear power actually reduces emissions of carbon dioxide when used in place of coal. Some believe that global warming means that it will become warmer all over. The name is misleading because in some places, it will actually become colder. The majority of scientists believe global warming is a process underway and that it is human-induced.
