Global Warming- Group 1

Global warming

The long-term rise in Earth's average surface temperature, primarily driven by increased concentrations of greenhouse gases in the atmosphere due to human activities like burning fossil fuels and deforestation.

Greenhouse gases

Gases such as carbon dioxide (CO2) and methane (CH4) that trap heat in the atmosphere, leading to the greenhouse effect and contributing to global warming.

Burning fossil fuels

The process of combusting natural resources such as coal, oil, and natural gas for energy, which releases large amounts of carbon dioxide into the atmosphere.

Deforestation

The large-scale clearing of forests, which decreases the number of trees that can absorb carbon dioxide, while also releasing stored CO2 into the atmosphere when trees are cut or burned.

Methane

A potent greenhouse gas produced during the digestive process of livestock, decomposition of organic waste, and extraction of natural gas, significantly contributing to global warming.

Waste dumping sites

Locations where waste is discarded without proper management, resulting in the emission of greenhouse gases such as methane and carbon dioxide as organic materials decompose.

Urban heat islands

Urban areas that experience significantly higher temperatures than their rural surroundings due to human activities, building density, and lack of vegetation, leading to increased energy use and greenhouse gas emissions.

Melting glaciers and ice caps

The reduction of polar ice and glaciers caused by rising global temperatures, which threatens freshwater supplies and contributes to rising sea levels.

Rising sea levels

The increase in the average level of the world's oceans, primarily driven by the melting of glaciers and thermal expansion of seawater, impacting coastal areas and ecosystems.

Agricultural disruption

The negative impact of global warming on agricultural practices, potentially altering planting seasons, crop growth, and reducing yields, leading to food shortages.

Health impacts of global warming

Adverse health effects resulting from global warming, including more frequent heatwaves and the increased spread of insect-related diseases, affecting vulnerable populations.

Carbon capture and storage (CCS)

A technology designed to mitigate climate change by capturing carbon dioxide emissions from power plants and industrial processes and storing it underground to prevent atmospheric release.

Electric vehicles (EVs)

Automobiles powered by electricity instead of fossil fuels, which help reduce greenhouse gas emissions, especially when charged using renewable energy sources.

Circular economy

An economic model focused on sustainability that aims to minimize waste by reusing, recycling, and regenerating resources, creating a closed-loop system beneficial for both the economy and the environment.

Community actions

Collective efforts by individuals and groups to combat climate change, such as promoting sustainable practices and reducing carbon footprints, which enhance public awareness and policy advocacy.
