Major impacts of global temperature rise.

global warming –

Due to the increasing process of industrialization, the amount of carbon-dioxide has increased in the atmosphere, which has given rise to the green house effect. The increase in the amount of carbon dioxide found on the earth prevents the thermal energy emitted by the rays reflected from the earth’s surface from leaving the atmosphere.

Major impacts of global temperature rise.

In this way, the concentration of thermal energy in the atmosphere leads to an increase in the average temperature of the earth, which is called global warming.

Major effects of global warming

Increase in Temperature

The concentration of Co2 is currently 340ppm and is expected to reach 640ppm by 2030. If this happens, then the average temperature of the earth will increase by 1.5 to 4.5 °C, due to which many terrible consequences can be faced by mankind.

Due to the rise in temperature, the glaciers of the Himalayas are turning into ice lakes. These lakes are getting wider every day. According to the international science journal ‘New Scientist’, all the glaciers of the Himalayas will be destroyed by 2025, during which severe flood situation can also arise.

Which will have an impact on the people living in the hilly areas around the valley. The melting of polar and high-mountain ice due to warming can drown many sea-side cities.

Melting of Polar Ice

About 7 million cubic meters of water is present in the form of frozen ice at the poles. If all this ice melts, then the sea level will rise to 7-8 m. It will rise to a high level, which will submerge many islands as a whole, but according to current estimates, 5 m above sea level. There is only the possibility of rising up.

Increase in Sea Level –

With an increase of 1.5-5.5 °C in the mean temperature of the earth, the sea level is likely to rise by 25-165 cm. The sea level rises due to two reasons, first the thermal expansion of sea water and secondly the melting of polar ice. There is a danger of being completely submerged.

Change in Weather –

An increase of 3 °C in the average temperature of the earth will increase the average temperature by 10 °C at higher latitudes. In the coming time, due to the greenhouse effect, the winter season will become short and humid and the summer season will become long and dry, due to the rise in temperature, evaporation will increase and rainfall will start increasing by 7 to 11%.

Effects on Species –

Every plant and animal lives in a particular temperature range. Due to global warming, the temperature will increase. In this case, many species may migrate to the poles and many species, which cannot migrate quickly, may also die. Many trees and plants may become extinct.

Food Production –

Global warming reduces the yield of crops due to increased incidence of pests and diseases of plants, overgrowth of grass and plant respiration.

It is estimated that rice production in Southeast Asia will decrease by 5% per 1°C of warming. Although the increase in CO2 concentration in the atmosphere helps in increasing the yield of crops, yet the total grain production of the world will decrease with increase in global temperature. Changes in the climate structure are also reflected in the form of famines.

According to a study by the US Environmental Protection Agency, by 2060 the world’s production of rice, wheat and other food grains will decrease by 1.2 to 7.6 percent. The rise in temperature will also accelerate the world water crisis.

Question and Answer (FAQ)

What is global warming.

Due to the increasing process of industrialization, the amount of carbon-dioxide has increased in the atmosphere, which has given rise to the green house effect. The increase in the amount of carbon dioxide found on the earth prevents the thermal energy emitted by the rays reflected from the earth’s surface from leaving the atmosphere.

What is the reason for the rise in temperature on earth?

In the emission of greenhouse gases such as carbon dioxide, methane, nitrous oxide, sulfur dioxide etc. rise earth average of Temperature In growth a chief of cause Is. Changes in land use are also responsible for this, as it increases the surface albedo. growth happened.
