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. 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.
Global warming is a danger to a human's health. Its affect on climate can adversely affect humans. Plagues have been attributed to global warming. An increase in temperature can result in a longer life cycle for diseases or the agents spreading them. Living in a warm area makes egg production a quicker process. Global warming will lead to more precipitation, which enables infectious diseases to be more easily contracted and spread. Effects of global warming on human health might not be immediately detected.
The future of earth's climate is in the hands of human. With simple measures, we as people of this earth, cannot seal our fate in rising temperatures, but rather we must change our views completely. It is scary of how much we have abused and taken advantage of this earth. I am troubled that our generation will suffer because of our lack of concern, knowledge, and greed. We have to stop thinking of the natural world as something that we can exploit, and start thinking of it as something that is crucial to our very existence. We must take responsibilities for our earth.
