Question

article on global warming in 80-90words

Answer 1

Global warming or climate change has today become a major threat to the mankind. The Earth’s temperature is on the rise and there are various reasons for it such as greenhouse gases emanating from carbon dioxide (CO2) emissions, burning of fossil fuels or deforestation.

Impact of Greenhouse Gases

The rise in the levels of carbon dioxide (CO2) leads to 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 the CO2 concentration in the atmosphere.

Global Warming: A Gradual Phenomenon

Recent years have been unusually warm, causing worldwide concern. But the fact is that the increase in carbon dioxide actually began in 1800, due to the deforestation of a large chunk of North-eastern American, besides forested parts of the world. The things became worse with emissions in the wake of the industrial revolution, leading to increase in carbon dioxide level by 1900.

Cause of Concern

According to the Intergovernmental Panel on Climate Change (IPCC), global temperature is likely to rise by about 1-3.5 Celsius by the year 2100. It has also suggested that the climate might warm by as much as 10 degrees Fahrenheit over the next 100 years.

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 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.

Answer 2

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 entrapment of greenhouse gases in the earth’s atmosphere.

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