Nowadays, the world is facing many problems due to the global warming. These problems are directly linked to human beings. Climate change occurs due to the global warming. Global warming is the long-term increase in Earth’s average temperature, primarily due to human activities. This phenomenon is a major aspect of climate change, which encompasses broader changes in temperature, precipitation patterns, and other climatic factors.

Greenhouse gases(CO2, CH4, N2O) and human activities such as burning fossil fuels, deforestation, industrial processes, and agriculture are the causes of global gases. Greenhouse gases trap the heat within the atmosphere of the Earth which increases the atmosphere of Earth. This additional trapped heat results in an increase in the overall temperature of the Earth’s atmosphere and surface. Human activities particularly the burning of fossil fuels, deforestation, and industrial emissions play a significant role in increasing the temperature of the Earth. Global warming is disturbing the normal functioning of human life. Global warming is the main cause of climate change.

History:

The historical backdrop of Climate change follows its foundations back to early logical perceptions, with key achievements including Joseph Fourier’s 1824 proposition of the nursery impact and Svante Arrhenius’ 1896 hypothesis connecting CO2 emissions to an Earth-wide temperature boost. The Modern Unrest catalyzed a critical expansion in ozone-depleting substance discharges because of the broad utilization of non-renewable energy sources.

By the mid-twentieth 100 years, mounting proof of climbing worldwide temperatures arose, with milestone concentrates, for example, Charles David Falling’s CO2 estimations and the 1979 Charney Report featuring the expected seriousness of environmental change. These authentic improvements laid the preparation for our ongoing comprehension of environmental change and its suggestions.

Causes:

Greenhouse Gas Emissions:

Human fulfill their energy requirement by burning fossil fuels (coal, oil, and natural gas). These fuels release large amounts of carbon dioxide (CO2), methane (CH4), and other greenhouse gases into the atmosphere. These gases trap the heat within the atmosphere of Earth. Consequently increases the temperature of Earth.

Deforestation:

Deforestation is one of the main causes of Climate Change. Plants absorb carbon dioxide and normalize its amount within the atmosphere. Deforestation reduces the number of trees that absorb the CO2 from the atmosphere. As a result, the quantity of CO2 in the atmosphere increases and heat also increases.

Industrial Processes:

Industries are increasing day by day to meet the requirements of human beings. Many industrial activities produce greenhouse gases and other pollutants. Industries such as cement production, steel manufacturing, and chemical processing release greenhouse gases in large amounts, which are very harmful to human beings.

Agriculture:

Agricultural practices, including domesticated animals cultivating, produce methane and nitrous oxide, intense ozone-depleting substances. The use of fertilizer and pesticides is also the source of emission of these gases.

Effects of Climate Change:

Temperature Change: Increased global temperatures can lead to more continual and severe heatwaves. It can also disrupt the rainfall system, consequently, the rain will become unpredictable. These things can lead to drought, flood, and other problems.

Melting Ice and Rising Sea Levels: As we explain above climate change raises the temperature. Due to the rise in temperature, glaciers and polar ice caps melt, which increases the sea level. When sea level rises, it increases hazards such as tsunamis and storms, which can be very dangerous for human beings.

Ocean Acidification: Increased CO2 levels lead to higher concentrations of carbonic acid in oceans, which lowers seawater pH and makes the availability of carbonate ions difficult for the marine organisms that build shells and skeletons, like corals and mollusks. Overall it affects the growth and survival capacity of these organisms.

Impact on Ecosystems and Biodiversity: Climate change leads to both Species Extinction and Shifts in Habitat, which can disrupt food chains and ecosystems. Species that cannot adapt to these environments and cannot migrate become extinct.

Many species are forced to move to a new place where there is a better environment for them, which can disrupt food chains and ecological balance.

Changes in Precipitation and Water Supply: As we mentioned above, climate change makes rain less predictable, Thus, some areas receive less rain and some receive heavy rain, which can cause problems such as drought and floods. Drought can be the cause of less rain, affecting water availability for drinking, agriculture, and industry and intense storms can lead to flooding, which damages infrastructure, homes, and agricultural land.

Agricultural Impact: Crops for optimal growth require a particular environment at a particular temperature. When Climate change disturbs the temperature which is sufficient for the growth of crops, it reduces food production and leads to food insecurity.

Human Health: Human beings require a balanced temperature for their survival. Due to climate change, the temperature is increasing. As a result, many diseases are occurring. Warmer temperatures create more favorable conditions for disease-carrying insects. These insects can cause diseases like malaria and dengue fever. Which can be very dangerous for human health.

What should we do?

To overcome Climate Change, we have to start an awareness campaign and make people aware of its drawbacks. Moreover, we have to shift from fossil fuels to renewable energy sources, such as solar and wind, that will reduce the emission of greenhouse gases. Vehicles also produce harmful gases, thus we have to support sustainable transportation options like electric vehicles and public transit, which can be very beneficial for the Earth and human health. Changes at required both at individual and systemic levels, in this way we can mitigate climate change and work towards a more sustainable future.
