Global Warming is directly linked to the concept of Greenhouse Gases. Energy from the sun drives the earth’s weather and climate, and heats the earth’s surface. In turn, the earth radiates energy back into space. Atmospheric greenhouse gases such as water vapor and carbon dioxide trap some of the outgoing energy and retain heat somewhat like the glass panels of a greenhouse. Without this natural ‘Greenhouse Effect’, temperatures on earth would be much lower than they are now and life as known today would not be possible.However, problems arise when the atmospheric concentration of greenhouse gases increases above the basic level.

Higher concentrations of greenhouse gases present in our atmosphere improves the heat-trapping ability of our earth. This results in a general increase in average temperatures of the earth, which modifies the weather balances and ecosystems for a long time, commonly known as Global warming.

Cause of Global warming essay : So what is causing this Global Warming? Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reasons for Global Warming as it increases the concentration of carbon dioxide the most important greenhouse gas of the atmosphere. There are certain natural sources of carbon dioxide too such as plant respiration and the decomposition of organic matter but these releases have generally been in balance during the centuries as carbon dioxide released were absorbed by terrestrial vegetation and the oceans.

What has changed in the last few hundred years is the additional release of carbon dioxide by human activities.Fossil fuels burnt to run cars and trucks, heat homes and offices and power factories are play a significant role in increasing the presence of these gases, thereby worsening the atmospheric balance and causing Global Warming. Increased agriculture, deforestation, landfills, industrial production and mining also contribute a significant share of this catastrophe.

Effect of Global warming essay  : Much to our dismay , Global Warming has reached alarming proportions and many effects of global warming have already started making their presence felt.  Extreme heat waves in summer , winter without snow, climate change , floods in one corner of a country while another undergoes terrible droughts, are some of the effects of Global Warming.

Beyond the climate, its consequences are much more complex.  The Arctic perennial polar ice cap is shrinking at the alarming rate of 9% per decade. Similarly, the recently reported retreat of the Himalayan glaciers, some of which feed major river systems, could have a catastrophic impact. Melting glaciers and ice caps will lead to rising sea levels, in turn leading to .coastal flooding all around the globe. Warmer sea surface temperatures will fuel more intense hurricanes. Many regions could also face troublesome new pests and many more mosquito borne diseases. Disruption of habitats such as coral reefs and alpine meadows could drive many species to extinction.

Global Warming Essay

Solution of Global warming essay :  In all this gloom and doom, the glimmer of good news rests solely in human hands. Technologies exist today to make cars that run cleaner and consume less fuel, electricity in be generated from renewable sources like solar, hydro power and even bio waste. Furthermore energy efficiency is now a new buzzword. Valuable research is being done to make fuel efficient cars and automobiles. LED bulbs which consume less power are being increasingly used in households and commercial establishments.

Conserving energy should be a part of the daily routine of an individual. The colossal threat of global warming can only be arrested by emission controls and energy efficiency. Governments across the globe have now woken up to this problem, which can spell doom mankind. International seminars are being held to reduce the carbon imprint, by making developed and developing nations agree to reduce pollution, emanating from the factories. However, the best answer to the danger of global warming is green activism, less profligate style habits and sustainable development.

 

Conclusion Of Global warming essay : Estimating the intensity of Global Warming in the future is difficult because it depends on demographic, economic, technological and industrial developments. However, in the absence of emission control policies, the future is undoubtedly very dark. The need of the hour is to realize the dangers that Global warming poses on humanity as well as all the living beings and working towards slowing down the effect of global warming by reducing greenhouse gas emissions. An integrated effort of all the humans is required for the same.
