Study Notes
Understanding Climate Change
- Climate change is driven by the accumulation of greenhouse gases, leading to long-term shifts in weather patterns and an increase in global temperatures, known as global warming.
- Climate refers to long-term atmospheric changes, while weather pertains to short-term atmospheric conditions.
- Effects of climate change include melting glaciers, rising sea levels, more intense droughts, severe storms, and heatwaves.
Causes of Climate Change
- Burning Fossil Fuels: Industrialized nations have altered the carbon cycle by extensively using fossil fuels (coal, oil, gas), releasing significant amounts of carbon dioxide into the atmosphere.
- Agriculture and Livestock: Intensive farming practices, particularly meat production, contribute large methane and nitrous oxide emissions, both potent greenhouse gases.
- Deforestation: Large-scale forest clearing reduces the planet's capacity to absorb carbon dioxide, exacerbating climate change impacts.
Impacts of Climate Change
- Global temperatures have risen by 1.2°C since the Industrial Revolution, leading to extreme weather events that threaten lives, wildlife, and ecosystems.
- Extreme weather events are now common, with significant costs for protection and recovery.
- Vulnerable populations, including indigenous groups and future generations, disproportionately bear the brunt of climate change effects.
- The Paris Agreement aims to limit global warming to below 2°C, ideally to 1.5°C, but current pledges may still lead to a 2.7°C rise.
Consequences of Exceeding 1.5°C
- Crossing the 1.5°C threshold could trigger catastrophic tipping points, leading to severe consequences like:
- Loss of coral reefs due to extreme ocean acidification.
- Mass species extinction and intensified wildfires.
- Severe storms and loss of ancient ice, contributing to significant sea level rise.
- Food security risks from failed crops and chronic water scarcity.
- Increased health risks, including heat-related illnesses and pandemics.
- Population displacement, resulting in climate refugees and heightened mental health challenges.
Taking Action Against Climate Change
- Urgent global actions are essential to mitigate climate change and its impacts, with every fraction of temperature rise posing increased risks.
- Societal systems—such as water supply, agriculture, and public health—will be affected, necessitating adaptive measures.
- Carbon dioxide remains in the atmosphere for about a century, meaning long-term warming is unavoidable unless substantial changes are made.
- Individual actions, such as reducing emissions through lifestyle changes, can contribute to the collective effort against climate change while promoting health and savings.
