At present, many types of climate crises have started arising in front of the life of all living beings on Earth, not only humans. The main reason for this is the continuous adverse changes in the Earth’s climate. Although there are frequent changes in the weather, climate change occurs only when these changes persist for the last few decades to centuries.
What Are The Causes of the Climate Change?
There has been a huge increase in the proportion of carbon dioxide in the atmosphere, due to which there have been many major changes in the Earth’s climate. In addition, over the centuries, many natural forces such as solar radiation, changes in the Earth’s orbit, and volcanic eruptions have been influencing the Earth’s climate conditions.
Apart from this, many human activities such as indiscriminate use of fossil fuels, continuous degradation of forests, excessive dependence on conventional sources of energy, etc. The recent change in climate conditions is also known as global warming.
What is the Evidence of Climate Change?
According to the Intergovernmental Panel on Climate Change (IPCC), the average temperature of the northern hemisphere in the latter half of the twentieth century was much higher than in the previous 500 years.
The iceberg is shrinking, and the rate of ice melting in Antarctica has tripled in the past decade. The past century has seen a rise of about 8 inches in global sea level.
The acidification of the oceans also confirms this. The amount of CO2 absorbed by the top layer of the oceans increases by about 2 billion tonnes per year.
The temperature of India has increased by about 2 °C since 1900.
What are The Effects of Climate Change?
Climate change is harming the Earth’s environment. These effects are being described here:
1. Impact on Forests
Many trees have become extinct due to their inability to cope with the ever-changing environment. Due to the mass extinction of trees and plants, biodiversity has decreased, which is bad for the environment.
2. Accelerated Sea Level Rise
By the year 2100, sea levels are projected to rise by 1 to 4 feet due to the increase in additional water from the melting of ice due to warming and the expansion of seawater.
3. Impact on Wildlife
Various wild animals, including tigers, African elephants, Asiatic rhinos, Adley penguins, and polar bears, have declined. Most of these species are on the verge of extinction as they cannot cope with the changing climate. Huh.
4. Nutritional Security:
Rising levels of atmospheric carbon dioxide decrease the concentration of proteins and essential minerals in most plant species, including wheat, soybeans, and rice. Due to extreme heat, wheat yield in the Indus-Gangetic plains can be reduced by 51 percent.
5. Effects on Water
Climate change has led to some dire conditions for water systems worldwide. Due to the changing weather conditions, the pattern of rainfall is changing worldwide, and due to this, the needs of flood or drought are being created in different parts of the Earth. Another important issue is the melting of glaciers due to increased temperature.
World Meteorological Organization (WMO) Secretary-General Petri Talaash says, “We are seeing the bitter truth of climate change with our naked eyes at present. He said these things given the weather events around the world between June-July 2021. Not only did extreme weather events occur in these two months, but their nature was also different. Decrease in soil moisture and increase the infestation of pests and diseases.
What Are The Ways to Avoid Climate Change?
Natural resources are not unlimited, and hence their consumption must be controlled and planned to ensure sustainable development. Nature-friendly alternatives like wind power, hydropower, solar power, geothermal, and biomass should be explored for power generation and adequately implemented in the system.
Apart from this, efforts should be made by conducting schemes like environmental impact assessment, afforestation program, green skill development program, promotion of organic agriculture, etc.
The negative effects on the climate due to the above-mentioned natural factors cannot be controlled. Still, those human activities which are the cause of air, land, and water pollution and which have negative effects on the climate must be banned. Can go, and each of us should do our part to control this global problem.
