Global warming refers to the long-term rise in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide, methane, and nitrous oxide. These gases trap heat in the atmosphere, leading to the gradual warming of the planet. As a result, glaciers and polar ice caps are melting, causing sea levels to rise and threatening coastal communities. Extreme weather events such as hurricanes, droughts, and heatwaves are becoming more frequent and intense. The warming also disrupts ecosystems, leading to biodiversity loss and endangering numer

Introduction to Global Warming Global warming refers to the long-term heating of the Earth’s climate system, primarily due to human activities such as the burning of fossil fuels, deforestation, and industrial processes. It leads to an increase in Earth's average surface temperature. By Simran
Causes of Global Warming 1 2 Greenhouse Gas Emissions Industrial and Agricultural Practices Human activities, including the burning of fossil fuels and deforestation, release greenhouse gases such as carbon dioxide and methane into the atmosphere. Manufacturing processes, intensive agriculture, and livestock farming contribute to the emission of greenhouse gases and environmental degradation. 3 Waste Mismanagement Improper disposal of solid waste and landfill management leads to the release of methane, a potent greenhouse gas, into the atmosphere.
Impact on the Environment Extreme Weather Events Melting Ice Caps and Glaciers Global warming intensifies weather patterns, leading to more frequent and severe hurricanes, heatwaves, and droughts. Rising temperatures result in the accelerated melting of polar ice, leading to rising sea levels and loss of habitat for polar animals. Disruption of Ecosystems Shifts in temperature and precipitation patterns disturb the natural balance of ecosystems, threatening plant and animal species.
Impact on Wildlife Polar Bears Coral Reefs Penguins Loss of sea ice habitat due to melting ice caps threatens the survival of polar bears. Rising sea temperatures pose a significant threat to the health and survival of coral reef ecosystems. Changing ocean conditions and scarcity of food affect the breeding success and survival of penguin populations.
Impact on Human Health Air Quality Vector-Borne Diseases Water Scarcity Higher temperatures and air pollution lead to increased respiratory problems and cardiovascular diseases. Changes in rainfall patterns and water availability affect water quality, sanitation, and the spread of water-borne diseases. Warmer climates expand the habitat of disease-carrying insects, leading to higher risks of dengue fever, malaria, and Lyme disease.
Mitigation Strategies 1 Renewable Energy Transition Shift from fossil fuels to renewable energy sources such as solar and wind power to reduce carbon emissions. 2 Afforestation Planting trees and restoring forests to sequester carbon dioxide and mitigate the effects of global warming. 3 Carbon Pricing Implement policies to put a price on carbon emissions, encouraging industries to reduce their carbon footprint.
International Efforts to Combat Global Warming Paris Agreement An international treaty aimed at limiting global warming and mitigating its effects. UN Framework Convention A global environmental treaty that sets the overall framework for intergovernmental efforts to tackle climate change. Montreal Protocol An international treaty designed to protect the ozone layer by phasing out substances that deplete it.
