Climate change/environment - Global Perspectives IGCSE Study Notes

Climate change refers to significant and lasting changes in the Earth's climate, primarily due to human activities, such as burning fossil fuels, deforestation, and industrial processes. These activities increase the concentration of greenhouse gases (GHGs) in the atmosphere, leading to global warming and various environmental challenges. This phenomenon affects weather patterns, causes sea-level rise, and has severe impacts on biodiversity and human health. Addressing climate change requires a comprehensive understanding of its causes and consequences, as well as collaborative approaches for mitigation and adaptation. In the context of Global Perspectives, students explore diverse viewpoints, evaluate evidence, and engage in discussions about responsibilities at local and global levels. Understanding the interconnectedness of climate issues will foster a sense of global citizenship and motivate students to seek solutions in their communities.

1. Greenhouse Effect: The warming of the Earth's surface due to trapped heat by GHGs. 2. Carbon Footprint: The total amount of greenhouse gases emitted by an individual, organization, or event. 3. Sustainable Development: Meeting the needs of the present without compromising the ability of future generations to meet their own needs. 4. Renewable Energy: Energy derived from natural processes that are continuously replenished, such as solar or wind power. 5. Adaptation: Adjusting to actual or expected climate changes to reduce harm or exploit beneficial opportunities. 6. Mitigation: Efforts to reduce or prevent the emission of GHGs to limit climate change. 7. Deforestation: The large-scale removal of forests, leading to habitat loss and increased atmospheric CO2. 8. Climate Resilience: The ability of a system to withstand and recover from climate impacts. Understanding these concepts helps students analyze various perspectives, assess evidence, and propose effective solutions to climate change challenges.
