The term “Global Warming” refers to the gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. The release of green house gases in the atmosphere causes the temperature to increase. There is a vivid rise in the level of carbon dioxide and other gases released by burning of fuels, agriculture and other activities. Greenhouse gases trap heat and keep it close to the Earth’s surface making it livable for humans and animals. However, the over emission of these gases and fossil fuels deteriorate the ozone layer protecting the surface of Earth.
SIGNS OF CLIMATE CHANGE
• ARCTIC SEA ICE – Arctic sea ice is declining at an alarming rate – 11.5% per decade. Arctic ice reaches its minimum every September.
• CARBON DIOXIDE (CO2) – It is a prevalent heat-trapping (greenhouse) gas released due to human activities like burning of fossils, pollutants from the factories and small scale industries. Scientists claim carbon dioxide level in the atmosphere is the highest now.
• GLOBAL TEMPERATURE – The year 2016 was recorded the warmest for the top 10 warmest year since 1880.
• SEA LEVEL – The rise in the sea level is a major cause of concern today. It is due to the melting of glaciers , and the expansion of sea water as it warms up.
With the onset of the industrial revolution in the 1700’s ,humans began emitting more fossil fuels (coal, oil and natural gas) to run cars, trucks and factories add up to climate change.
Warming has observable effects on the environment. Glaciers are shrinking, ice on rivers and lakes drying up. It also poses a great threat to the flora and fauna. The plant and animal life is affected too. They have shifted grounds and trees are flowering sooner.
Heat waves caused by global warming pose a greater risk of heat-related illness and death in human beings.
It puts coral reefs in danger as the ocean warms resulting in incidents of bleaching.
As humanity strives to achieve better living standards for all, there’s an hunger for development. As a result of which, development possesses a threat to mankind.
We can help prevent global warming in numerous ways. Efficient use of energy, afforestation, Car pool, adopting a clean approach for the environment are the different ways to help prevent global warming. Every individual should be aware of the importance of protecting the environment. With effective co -operation from citizens and government officials only, we may be able to slow down the effects of global warming.
