Short Essay On Global Warming And Its Effects.
Global Warming: The Main Cause And Effects Of Global Warming. Global warming is the gradual rise in temperature of the air and water near the earth 's surface. The average temperature of the earth has risen about 1 degree Celsius over the past 100 years. Even though many people believe they know why this is happening, the exact cause is unknown.
Global warming is a multi-faceted phenomenon that will have severe consequences if current trends continue. Melting glaciers, rising sea levels, warmer sea surface temperatures and habitat disruption are all consequences associated with global warming. Modern technologies has begun to curb the effects of global warming.
Estimating the effects of feedback processes, the pace of the warming, and regional climate change requires the use of mathematical models of the atmosphere, ocean, land, and ice (the cryosphere) built upon established laws of physics and the latest understanding of the physical, chemical and biological processes affecting climate, and run on powerful computers.
Global warming has brought about possibly irreversible alterations to Earth's geological, biological and ecological systems. These changes have led to the emergence of large-scale environmental hazards to human health, such as extreme weather, ozone depletion, increased danger of wildland fires, loss of biodiversity, stresses to food-producing systems and the global spread of infectious diseases.
The adverse effects of global warming have prompted the worldwide leaders and scientists to come up with ways of curbing global warming. Some of these methods range from moving away from utilizing fossil fuel and switching to using alternative sources of energy such as solar, wind and nuclear to modification of our human behaviors to limit our carbon footprint.
Projected changes in temperature and precipitation under global warming are likely to lead to other effects that threaten human health and safety. For example, changing precipitation patterns and prolonged heat can create drought, which can cause forest and peat fires, putting residents and firefighters in danger.
Global warming is the ongoing rise of the average temperature of the Earth's climate system and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. It is a major aspect of climate change which, in addition to rising global surface temperatures, also includes its effects, such as changes in precipitation.
