What is Global Warming?

Increase in average temperature on Earth’s climate & oceans due to natural greenhouse effect caused by the greenhouse gases is said to be the global warming phenomenon.

From the day human started using fossil fuels, CO2 (Carbon dioxide) in the atmosphere started building up. Being a green house gas, CO2 can trap the warmness from dispersing to the sky. This speciality of CO2 now results in global warming.

Impact of Global Warming

Global warming can affect both plant and animal species. The major impact of the global warming will be decrease in polar ice caps, which results in rise of ocean water level, which in effect brings low lying cities under the sea.

The increase amount of fresh water can also affect the flow of Thermohaline circulation, the ocean current powering our climate. Hence any change to this current can adversely affect the world’s climate. Hurricanes of large magnitudes, floods, droughts and other extreme weather anomalies are the predicted results of global warming.

Global warming also results in ice-albedo feedback. When ice melts, these areas will either become land or ocean. Both land and ocean are less reflective and can absorb large
amount of heat. This in turn warms the climate and results in more melting of ice. Thus global warming can increase the effect of global warming.
