Top 10 Must Read Topics for IAS Mains GS Paper 3 | Impact of carbon dioxide on the environment

Today we will discuss THE NEXT Topic. Below mentioned is the explanation of the said topic.

Carbon Dioxide

Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 60% higher than that of air (1.225 g/L) that is odorless at normally encountered concentrations. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth’s atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas.

What causes carbon dioxide build up in the atmosphere?
Carbon dioxide causes about 20 percent of Earth’s greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. The rest is caused by small particles (aerosols) and minor greenhouse gases like methane. Water vapor concentrations in the air are controlled by Earth’s temperature.

Impact Of Carbon dioxide on Environment

Carbon dioxide is essential to the survival of plants and animals. Too much, however, can cause all life on Earth to die. Not only do plants and animals need to ingest carbon dioxide, but they also rely on the gas to keep them warm, as it is an essential component to Earth’s atmosphere.

Plants

Plants remove carbon dioxide from the atmosphere in a process called carbon sequestration. The carbon dioxide is stored in biomass then released by the plant. In most cases, the amount released is less than the amount consumed by the plant. Farms, grasslands and forests are considered sources or sinks of carbon dioxide, depending on the practices on these lands.

Green House Gas

Carbon dioxide is a naturally occurring greenhouse gas. Others include water vapor, methane and nitrous oxide. These gases help keep the Earth warm by absorbing the sun’s energy and by redirecting energy back to the Earth’s surface. An increase in the amount of carbon dioxide creates an overabundance of greenhouse gases that trap additional heat. This trapped heat leads to melting ice caps and rising ocean levels, which cause flooding.

Greenhouse effect

Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.

Global warming

The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.
