Why should we care about CO2 and climate change?

Understanding greenhouse gas emissions

Greenhouse gases like carbon dioxide (CO2), methane, and water vapour trap heat in the Earth’s atmosphere. This is known as the greenhouse effect. 

Burning coal, oil, and gas releases CO2, increasing its atmospheric concentration. This higher concentration means more heat is trapped, warming the Earth.

Impacts of carbon dioxide on global warming

Higher temperatures lead to melting ice caps and glaciers, rising sea levels, and threats to coastal areas. More heat also means more intense and frequent weather events, such as hurricanes and droughts.

Higher temperatures affect ecosystems and species. For instance, coral reefs suffer from bleaching due to warmer waters. Many plants and animals may struggle to survive or adapt to rapidly changing conditions.

Research on climate change and emissions

Scientists study climate change to understand how CO2 affects the planet and use computer models to predict future global warming scenarios.

These models help scientists understand potential outcomes based on different levels of CO2 emissions.

Research shows that reducing CO2 emissions can slow down global warming. Innovations in technology, policy changes, and international cooperation are essential to achieving this goal.

Health benefits of CO2 reduction

Carbon dioxide emissions greatly constrain human health. Reducing them can lead to better air quality, fewer health risks, and fewer premature deaths.

1. Improvements in air quality

Reducing CO2 emissions directly leads to cleaner air. Using clean energy sources like wind and solar power reduces harmful air pollutants such as nitric oxide and sulfur dioxide, known to cause respiratory problems and cardiovascular diseases.

Better air quality means people breathe cleaner air. This reduces the incidence of asthma and other lung diseases and improves overall lung function, especially in children and the elderly.

Communities near industrial zones benefit the most as they usually deal with higher pollution levels.

2. Reduction of public health risks

Cutting CO2 emissions benefits public health. High levels of air pollution have been linked to increased hospital visits for heart and lung conditions. When emissions drop, there are fewer instances of these medical emergencies.

Cleaner air means less exposure to harmful chemicals and particles. This lowers health risks related to long-term exposure, such as chronic bronchitis and heart attacks.

Healthier environments contribute to a better quality of life. People enjoy outdoor activities more, reducing risks associated with sedentary lifestyles, like obesity and diabetes.

3. Minimising premature deaths

Reducing CO2 reduces air pollution, which helps lower the rate of premature deaths. Air pollution is a significant factor in premature deaths, mainly due to heart disease and lung cancer. Improved air quality saves lives by reducing these health threats.

In regions with significant pollution, cutting emissions can lead to a noticeable decrease in premature death rates. According to research published in The Lancet, emissions reduction can decrease deaths caused by fine particulate matter (PM 2.5).

4. Promoting environmental justice

Environmental justice ensures that all communities receive equal protection from environmental hazards. 

Marginalised communities often face disproportionate impacts of climate change. By reducing emissions, these communities can experience better health outcomes and opportunities for growth. Addressing these issues through climate policies ensures that benefits are distributed fairly.

Empowering communities with cleaner technologies and involving them in decision-making processes underscores the importance of fairness in environmental efforts.

Environmental and ecological advantages

Reducing CO2 emissions is crucial in preserving ecosystems and combating climate change. It helps prevent extreme weather events and supports natural methods of absorbing carbon.

5. Preservation of ecosystems

High levels of CO2 lead to changing climates that harm plant and animal habitats. For example, increasing temperatures can push species out of their natural homes, leading to biodiversity loss.

  • Healthy ecosystems can resist changes better. Forests, wetlands, and coral reefs thrive with stable temperatures and weather. When CO2 levels drop, these areas can support more species.
  • Soil health also improves when CO2 emissions decline. Less pollution means that soil can maintain its nutrients. Rich, fertile soil supports plant life and helps ecosystems stay vibrant.

6. Mitigation of extreme weather events

Lower emissions mean fewer severe storms, floods, and droughts. These weather events often result from climate imbalance caused by high CO2.

Flood reduction is a direct benefit. With stable CO2 levels, rainfall patterns become more predictable. This stability reduces the likelihood of heavy rains that cause floods.

Stronger resilience against droughts and heat waves is another benefit. With less CO2, temperatures remain steady, reducing the chance of extreme heat. This helps communities and ecosystems cope better with weather changes.

7. Encouraging nature-based solutions for carbon sequestration

Nature-based solutions are vital in the fight against CO2. These methods use natural processes to remove carbon from the air, and plants, trees, and soils are key players in these processes.

  • Forests act as carbon sinks. Trees absorb CO2 during photosynthesis, storing carbon in their wood and leaves. Healthy forests can lock away large amounts of carbon, making them essential in tackling climate change.
  • Soil management also plays a part. Techniques like no-till farming increase soil’s carbon storage. Healthier soils trap more CO2, decreasing the amount in the atmosphere.
  • Wetlands and peatlands are other natural solutions. They store significant amounts of carbon, helping reduce CO2 levels and protect the environment.

Economic benefits and growth opportunities

Reducing CO2 emissions creates opportunities for sustainable economic growth, job creation in the green sector, and investment in clean energy innovations.

8. Fostering sustainable economic growth

As economies reduce their reliance on coal-fired power plants and shift to renewable energy sources like wind and solar, they create more robust and resilient economic systems.

Clean energy sources can lead to lower energy costs in the long term, making businesses more competitive.

Adopting renewable energy benefits developing economies particularly. These countries can build modern energy infrastructures without the burden of outdated technologies.

This shift can result in GDP growth and greater economic stability. Additionally, the private sector sees reduced risks and increased opportunities for profitability when energy costs are stable and predictable.
