Question

what is the global warming ​

Answer 1

Global Warming:

• Global Warming is the phenomenon of rise in earth's temperature due to the absorption of radiation coming from sun by  greenhouse gases present in earth's atmosphere.

• Greenhouse gases such as carbon dioxide(CO₂), methane(CH₄), water vapour(H₂O), nitrous oxide(N₂O), etc. are major contributors to global warming.

• From 1970 to 2011, CO₂ emissions increased by 78%.
• The decade from 2010 to 2019 was the warmest decade on record worldwide.
• U.S., China and India are the largest emitters of human-induced greenhouse gases.

Innovative Step taken to reduce CO₂

New Zealand recently passed a law to reduce its emissions in a bid to become mostly carbon neutral by 2050.

Answer 2

Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

Global warming is the phenomenon of gradual increase in temperature near the Earth’s surface. This phenomenon has been observed over the past one or two centuries. This change has disturbed the climatic pattern of the earth. However, the concept of global warming is quite controversial. But, the scientists have provided relevant data in support of the fact that the temperature of the Earth is rising constantly.

There are several causes of global warming which have a negative effect on human, plant and animal lives. These causes may be natural or might be the outcome of human activities. In order to curb the issues, it is very important to understand the negatives of global warming.

Effects of Global Warming

Following are the major effects of global warming:

Rise in Temperature

Global warming has led to an incredible increase in earth’s temperature. Since 1880, the earth’s temperature has increased by 1.4 degrees. This has resulted in an increase in melting of glaciers which have led to an increase in the sea levels. This could have devastating effects on coastal regions.

Threat to the Ecosystem

Global warming has affected the coral reefs that can lead to a loss of plant and animal lives. Increase in global temperatures has made the fragility of coral reefs even worse.

Climate Change

Global warming has led to a change in climatic conditions. There are droughts at some places and floods at some. This climatic imbalance is the result of global warming.

Spread of Diseases

Global warming leads to a change in the patterns of heat and humidity. This has led to the movement of mosquitoes that carry and spread diseases.

Decrease in the Human Population

Due to an increase in floods, tsunamis and other natural calamities, the population of humans tend to decrease. Also, the spread of diseases leads to a decrease in the human population.

Loss of Natural Habitat

A global shift in the climate leads to the loss of habitats of several plants and animals. In this case, the animals need to migrate from their natural and many of them even get extinct. This is yet another major impact of global warming on biodiversity.
