The greenhouse effect, the main cause of climate change

Global industrial development, population growth and ever-increasing energy demand have created environmental problems, which are global. Carbon dioxide has a concentration of about 0.03% in our atmosphere. This concentration is continuously increasing due to the combustion of fossil fuels with the increase in the use of vehicles etc. If this situation continues without any corrective measures, the concentration of carbon dioxide could double in 2030.

What is the greenhouse effect?

The greenhouse effect is a natural process in which certain gases, known as greenhouse gases, trap heat that radiates from the earth’s surface. In fact, a greenhouse is a construction of transparent walls and roofs in cold countries to provide adequate heat to the soil and plants. Solar heat/energy enters the greenhouse but it is prevented from escaping, and this heat stays inside the greenhouse, keeping it warm. The greenhouse metaphor refers to the fact that greenhouse gases work much like the pane of glass that traps heat inside the greenhouse.

It is a natural phenomenon in certain atmospheric gases, such as water vapor and carbon dioxide, which regulates radiant energy and maintains the balance of the earth, thus making it habitable. The term “greenhouse effect” was first used in 1827 by Jam. Further away.

Importance of the greenhouse effect

If there were no greenhouse effect and the atmosphere became transparent to the outgoing emission of long-wavelength radiation from the Earth’s surface, the average equilibrium surface temperature of the Earth would be considerably low and probably below the freezing point of water. According to one estimate, in the absence of greenhouse gases, the average global temperature of the Earth will be 18°C, rather than its current temperature. These greenhouse gases act as a thermal blanket.

Causes of the greenhouse effect

Although there are a lot of greenhouse gases, carbon dioxide is a worse offender than all the others. This is mainly due to its pure qualities, which human activities generate through the burning of fossil fuels. Scientists recognize five important greenhouse gases, namely carbon dioxide, water vapour, chloro-fluoro carbon, methane and nitrous oxide. Besides these, ozone is also considered a greenhouse gas.

Impact of greenhouse effects

Climate change and global warming is the main impact of the greenhouse effect, some interrelated effects are as follows

Gradual increase in the temperature of the earth’s surface and the lower atmosphere. The temperature on earth could increase by about 1.5 to 4.5°C by 2050.

Photosynthesis, water use efficiency and plant yield would decrease. Photosynthesis by phytoplankton in the aquatic ecosystem would also be markedly reduced

Human health will also be affected. People will face food shortages due to shortage of agricultural crops.

A sudden change in climate leads to cyclones and other natural disasters that are already happening.

By most estimates, an average increase of 2°C in global temperature would warm Antarctica by 5°C.

This rise in temperature is sufficient for the melting and disintegration of the ice sheet. This will raise the sea level by 16 to 20 feet.

Greenhouse gas control efforts

Due to overwhelming scientific evidence and growing political interest, global warming is now recognized as an international problem. The Kyoto protocol was made for this purpose in 1997. More than 126 countries have ratified this protocol. This growing scientific consensus on global warming, coupled with the precautionary principle and fear of non-linear climate transitions, is leading to an increase in actions aimed at mitigating global warming. There are four categories of actions that can be taken to mitigate global warming.

Reduction of energy consumption

Switching from a carbon-based fossil fuse to alternative energy sources.

Carbon capture and storage

Geoengineering includes carbon sequestration.

Other global warming migration strategies include the development of new technologies, wind, nuclear, renewable energy, biodiesel, electric or hybrid automobiles, fuel cells and energy savings, taxes on carbon, etc Certain individual actions should also be encouraged against global warming.

Climate change and global warming

Virtually all scientists agree that if greenhouse gases increase and all other factors remain the same, the Earth will get warmer. Climate is the most important environmental variable on planet Earth. How climate forces interact is poorly understood and it is possible that some factors counteract warming just as other factors amplify it. According to a recent report, the climate is getting warmer and the effect of global warming is becoming increasingly noticeable in countries like the UK which are known to have a cold climate.

Climate change due to the burning of fossil fuels is one of the biggest problems facing humanity today. The burning of fossil fuels such as oil, coal, and gas results in the production of carbon dioxide and other gases that cause global warming.

The world is experiencing the biggest thaw since the last Ice Age. Much of Siberia is 3-5°C warmer than at the start of the 20th century. European alpine glaziers have lost half their volume since 1850. In Antarctica, a penguin population has crashed and the population of krill, a food source for many marine animals, has declined, apparently killed by warmer waters . Much of the tropics have become hotter and drier, especially in already arid regions. Another expected effect is the rise in sea level, due to the melting of the polar caps.

Climate change could lead to the extinction of many animals, including migratory birds. Global warming has already altered the migratory roots of some birds and can have a dramatic impact on wildlife with the rapid depletion of the tiny planktonic organisms that form the ocean’s food web. This is thought to have contributed to a recent drastic drop in the reproductive rates of some seabirds, as the fish they depend on were suddenly starved of food.
