Study Notes
- Since the industrial revolution in the mid-19th century, global temperatures have risen by about one degree Celsius according to climate experts.
- A temperature increase of 1.5 to 2.5 degrees Celsius globally could put 20 to 30% of studied plant and animal species at risk of extinction.
- Climate change impacts ecosystems, such as coral reefs, which provide important ecological services like coastal protection and habitat for marine life.
- Coral bleaching, caused by stress from increased ocean temperatures, leads to the expulsion of symbiotic algae, potentially resulting in coral death.
- The rise in ocean temperatures also forces marine species to migrate to deeper waters or higher latitudes, significantly impacting fishing activities.
- Climate change affects human societies through increased heatwaves, rising sea levels, and the potential displacement of millions of people as climate refugees.
- Mitigation strategies to limit global warming include individual actions like reducing greenhouse gas emissions, as well as collective efforts such as transitioning to renewable energy sources.
- Carbon storage techniques, like increasing natural carbon sinks and implementing industrial carbon capture and storage, are proposed to mitigate climate change effects.
- Adaptation strategies focus on reducing the vulnerability of natural and human systems to climate change impacts, such as planting trees to lower urban temperatures or building barriers to protect against rising sea levels.
- The complexity of choosing mitigation and adaptation solutions lies in considering their costs, environmental consequences, and societal acceptability.
Explore the impacts of climate change on ecosystems, species, and human societies, as well as the mitigation and adaptation strategies to address global warming. Learn about coral bleaching, species migration, rising temperatures, and ways to reduce greenhouse gas emissions.
