Question

article on global warming in 100 words

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 in 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.

Answer 2

                                    Global Warming

By Riya

Global warming is a long-term increase in the normal heat of the Earth's atmosphere regularity, a feature of climate variation revealed by heat measurements and by many outcomes of the warming. The results of global warming are the environmental and material changes generated (directly or discursively) by human emissions of greenhouse gases. It has severely harmed our environment. The modern technology we are using these days emits very harmful gases and the chemical drained by the factories has created a lot of problems to the life of the earth. The earth has observed extensive fluctuations in the temperature due to global warming. The emission of greenhouses gases has become so active that they have caused the melting of the glaciers and changes in the shift of climatic cycle. Therefore we have to save our earth by stopping more emission of these harmful gases.
