Study Notes
Climate Change
- Climate change involves long-term shifts in temperatures and weather patterns.
- Natural factors like solar activity and volcanic eruptions can cause shifts, but human activities are the primary driver since the 1800s.
- Burning fossil fuels (coal, oil, and gas) releases greenhouse gases.
- Greenhouse gases trap heat, leading to a warming effect.
- Key greenhouse gases include carbon dioxide and methane.
- Activities like driving cars and heating buildings release these gases.
- Clearing land and deforestation also release carbon dioxide.
- Agriculture, oil and gas, and land use are significant sources of methane emissions.
Human Responsibility for Global Warming
- Humans are responsible for almost all global warming in the last 200 years.
- Current human activities are causing global warming faster than any time in at least the past 2000 years.
- The current average global surface temperature is 1.2°C warmer than the late 1800s (pre-industrial era).
- The last decade (2011-2020) was the warmest on record and each of the last four decades has been warmer than any previous decade since 1850.
Consequences of Climate Change
- Climate change impacts various aspects of our lives.
- Impacts include intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms, and declining biodiversity.
- Impacts on human health, food production, housing, safety, and work are significant.
- More vulnerable groups (small island nations, developing countries) are disproportionately affected.
- Displacement and famine are possible consequences.
Addressing Climate Change
- Scientists and governments agree that we must limit global warming to no more than 1.5°C.
- Current policies indicate a possible warming of 3.1°C.
- Solutions include cutting emissions (fossil fuels to renewables, like solar and wind), adapting to climate impacts, and financing adaptations.
- Developed nations need to support developing nations to adapt.
Global Responsibility for Addressing Climate Change
- In 2023, the Russian Federation, Brazil, and the United States accounted for over half of global greenhouse gas emissions.
- The 47 least developed countries accounted for only 3%.
- Everyone needs to take action, but those responsible for the most emissions have greater responsibility.
