Global Warming

Global warming or climate change has become a worldwide concern. It is gradually developing into an unprecedented environmental crisis evident in melting glaciers, changing weather patterns, rising sea levels, floods, cyclones, and droughts. Global warming implies an increase in the average temperature of the Earth due to the entrapment of greenhouse gases in the earth’s atmosphere.

There is a need to raise awareness about global warming if we have to save the world from disaster.

Impact of greenhouse gases.

The rise in the levels of carbon dioxide (CO2) leads to a substantial increase in temperature. It is because CO2 remains concentrated in the atmosphere for even hundreds of years. Due to activities like fossil fuel combustion for electricity generation, transportation, and heating, human beings have contributed to increase in the CO2 concentration in the atmosphere.

Impact of global warming.

• The sea levels are constantly rising as freshwater marshlands, low-lying cities, and islands have been inundated with seawater.

• There have been changes in rainfall patterns, leading to droughts and fires in some areas, and flooding in other areas.

• Ice caps are constantly melting posing a threat to polar bears as their feeding season stands reduced.

• Glaciers are gradually melting.

• Animal populations are gradually vanishing as there has been a

• widespread loss of their habitat.

Conclusion.

As per the Kyoto protocol, developed countries are required to cut back their emissions. There is a need to reduce coal-fired electricity, increase energy efficiency through wind and solar power, and also high-efficiency natural gas generation.
