What is global warming?

The phrase “global warming” describes the gradual rise in the planet’s average surface temperature brought on by the atmospheric accumulation of greenhouse gases. The combustion of fossil fuels like coal, oil, and natural gas, which releases significant amounts of carbon dioxide (CO2) and other greenhouse gases into the atmosphere, is the main human activity that contributes to global warming.¬†

Here are some important details regarding global warming:

Greenhouse Effect:

The greenhouse effect is a natural mechanism that aids in controlling the temperature of the Earth. The atmosphere contains gases like carbon dioxide, methane, and water vapor that capture solar heat and keep it from escaping back into space. The existence of life on Earth depends on the natural greenhouse effect. However, because of human activity, the concentration of greenhouse gases has increased, intensifying the greenhouse effect and causing global warming.

Climate Change:

Climate change, which is the long-term alteration of temperature patterns, precipitation, wind patterns, and other features of the Earth’s climate system, is a result of global warming. Weather patterns, ecosystems, and sea levels are all affected by climate change, which may have a profound influence on human society and the environment.

Greenhouse Gas Emissions:

The rise in greenhouse gas emissions, mostly from the burning of fossil fuels for energy generation, transportation, industry, and deforestation, is the main cause of global warming. These operations cause significant atmospheric emissions of CO2, methane (CH4), and nitrous oxide (N2O). Agriculture and animal production are two more human endeavours that contribute to greenhouse gas emissions.

Consequences:

Rising global temperatures, the melting of glaciers and polar ice caps, rising sea levels, altered precipitation patterns, more frequent and severe weather events (like heatwaves, droughts, and hurricanes), disruptions to ecosystems and biodiversity, and effects on human health and livelihoods are just a few of the effects of global warming.

Adaptation and Prevention:

Strategies for both mitigation and adaptation are needed to combat global warming. In order to lessen greenhouse gas emissions, mitigation measures include switching to renewable energy sources, increasing energy efficiency, and implementing sustainable land-use techniques. Implementing agricultural practises that are adaptable to shifting conditions or developing infrastructure to survive extreme weather occurrences are examples of adaptation strategies.

International Agreements:

The necessity of combating climate change and global warming has been acknowledged by the worldwide community. As a global agreement to address the issue, the United Nations Framework Convention on Climate Change (UNFCCC) was created in 1992. With the goal of keeping global warming well below 2 degrees Celsius over pre-industrial levels and pursuing efforts to keep the temperature increase to 1.5 degrees Celsius, the Paris pact was ratified in 2015 and is a historic international pact.
