Model Essay for students on global warming.
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.
In the case of global warming, the question is: What is causing the increase in CO 2 concentrations? The answer turns out to be incontrovertible. The isotopic composition of carbon in atmospheric CO 2 provides a unique “fingerprint” that tells scientists that the lion’s share of the additional CO 2 accumulating in the atmosphere is from the burning of fossil fuels. Argument 2: No one.
Global warming - Global warming - Environmental consequences of global warming: Global warming and climate change have the potential to alter biological systems. More specifically, changes to near-surface air temperatures will likely influence ecosystem functioning and thus the biodiversity of plants, animals, and other forms of life. The current geographic ranges of plant and animal species.
Historical weather patterns are becoming less useful for predicting the future conditions because global warming is changing ocean and atmospheric conditions. In 30 to 50 years’ time, the Earth’s weather generating system will be entirely different, he predicted. Stephen Leahy, Global Warming May Spawn More Super-Storms, Inter Press Service, September 20, 2004 Extreme weather events on the.
Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as it radiates back into space. As the greenhouse gases build up in the atmosphere the Earth gets hotter. This process is leading to a rapid.
The hazard of global warming is continuously causing major damage to the Earth's environment. Most people are still unaware of global warming and do not consider it to be a big problem in years to.
Global warming Global warming is a well-recognised concept since the mid 1900s. The current issue in question revolves around the extent climate change will affect mankind, the timescale and the severity of such changes. Various visible physical changes are evident over the last decade. Not only does the disasters strike more frequently and with more force, all three major global surface.
