Flashcards

Climate change mitigation

Reducing greenhouse gas emissions to prevent further warming of the planet. This involves switching to renewable energy sources, improving energy efficiency, and reducing deforestation.

Climate change adaptation

Adjusting to the unavoidable impacts of climate change, like rising sea levels or more extreme weather. This includes building seawalls, developing drought-resistant crops, and improving early warning systems for disasters.

Energy transition

The process of shifting energy systems from fossil fuels (like coal, oil, and gas) to renewable sources like solar and wind power.

Net Zero Emissions

A situation where a country or organization aims to release no more greenhouse gases than it can absorb through natural processes or technologies.

What is Climate Change?

Climate change is a process where the Earth's temperature, rainfall, wind, and other weather elements vary over long periods (decades or longer). These changes can occur naturally, but humans are currently causing rapid warming primarily by burning fossil fuels, which release greenhouse gases.

How do greenhouse gases impact climate?

Greenhouse gases act like a blanket around the Earth, trapping the sun's heat and causing temperatures to rise. This is primarily caused by human activities, such as burning fossil fuels for transportation and energy production.

What are some examples of greenhouse gases?

Carbon dioxide and methane are major greenhouse gases. They are released from burning fossil fuels (like gas and coal), deforestation (clearing forests), and waste disposal (like landfills).

How much are greenhouse gas levels increasing?

The concentration of greenhouse gases in the atmosphere is higher than it has been in 2 million years. This means that the Earth is warming faster than ever before, and the last decade was the hottest on record.

What are the consequences of climate change?

Climate change has serious consequences, including intense droughts, water shortages, wildfires, rising sea levels, flooding, melting ice caps, powerful storms, and declining biodiversity. These impacts affect different places and people in various ways.

How does climate change affect people?

Climate change affects our health, food production, housing, safety, and work. People living in vulnerable areas, like small island nations facing rising sea levels, are disproportionately impacted.

How can we limit climate change impacts?

Scientists agree that limiting global temperature rise to no more than 1.5°C would help prevent the worst impacts of climate change. However, current emissions trends could result in a much higher temperature increase by the end of the century.

Why does every increase in global warming matter?

Every increase in global warming matters. Limiting global temperature rise is essential to avoid the worst impacts of climate change, which could include extreme weather events and rising sea levels.

Study Notes

Climate change is a natural phenomenon characterized by long-term variations in temperature and other factors. However, the current rapid warming is driven by human activities, particularly fossil fuel combustion, which releases greenhouse gases like carbon dioxide and methane. These gases trap heat, leading to an increase in global temperatures, currently about 1.1°C higher than in the 1800s. The impacts include droughts, rising sea levels, and effects on health and security, especially for vulnerable populations.

Solutions and Actions

  • Global warming must be limited to no more than 1.5°C to avoid the most severe climate impacts.
  • Transitioning from fossil fuels to renewable energy sources (e.g., solar) reduces greenhouse gas emissions.
  • Climate solutions can deliver economic benefits while protecting the environment.
  • Global agreements like the UN Framework Convention on Climate Change and the Paris Agreement guide climate action.
  • Adapting to climate change impacts is crucial for protecting people, homes, businesses, and ecosystems.
  • Investing in disaster preparedness (e.g., early warning systems) and climate adaptation delivers significant benefits.
  • Developed countries have a responsibility to provide financial assistance to developing countries to help them adapt to climate change.
  • Significant financial investments are needed for climate action to be successful.

Key Statistics and Impacts

  • 10 largest emitters make up 68% of emissions, compared to the 100 least emitting countries holding 3%.
  • Emissions reductions must be implemented starting now. Halving emissions by 2030 is essential.
  • Global temperature increase of up to 4.4°C by the end of the century is a possible outcome without significant action.
