Key strategies for responding to global warming and climate change

How a country responds to global warming and climate change is a government decision. Organisations and individuals may support that decision and cooperate. Or they might try to change the official response.

Core responses to climate change

• Reducing greenhouse gas emissions - Joining the global effort to lower the release of gases that contribute to global warming.
• Conserving forest ecosystems - Protecting and conserving forests.
• Safeguarding fragile environments - Identifying environments that will become more fragile as a result of climate change, and then deciding what should be done.
• Protecting coastal regions - Identifying coastal areas that will be threatened by flooding or marine erosion and deciding what action needs to be taken.

Global efforts to reduce greenhouse gas emissions

Addressing climate change requires a collective global approach, especially from countries with the highest emissions.

Major contributors to GHG emissions

International agreements on emissions reduction

• Kyoto Protocol (1997) - Established during a summit in Kyoto, Japan, this treaty aimed for countries to reduce their GHG emissions by an average of 5% by 2012, using 1990 levels as a baseline. The goal was to slow the pace of global warming through binding commitments.
• Paris Agreement (2015) - A more recent global framework designed to limit temperature rises to well below 2°C above pre-industrial levels. It requires substantial action from major polluters and becomes effective only when at least 55 countries, representing 55% of global emissions, commit to specific reduction targets. Key nations like China, the USA, and the UK signed up in 2016, marking a significant step forward.

National responses to climate change in different countries

Countries at varying stages of development adopt diverse strategies to combat climate change, reflecting their economic capabilities, environmental priorities, and societal needs. These responses often balance mitigation efforts with adaptation to changing conditions.

Examples of tailored national policies

• Developed nations - Countries like the UK often focus on cutting emissions through renewable energy adoption and stricter regulations, leveraging advanced technology and resources.
• Emerging economies - Nations such as China, while major emitters, are investing in both emission reductions and sustainable growth to balance industrial demands with environmental goals.
• Developing countries - Places like Sri Lanka prioritise adaptation to immediate climate impacts, such as rising sea levels, alongside smaller-scale mitigation efforts due to limited resources.

Importance of protecting forests and fragile environments

Forests and other sensitive ecosystems play a vital role in regulating the Earth's climate. Protecting these areas is a critical response to global warming, as they help absorb carbon and maintain ecological balance.

Benefits of forest conservation

• Carbon sequestration - Forests act as natural storage for carbon, reducing the amount of GHGs in the atmosphere.
• Biodiversity preservation - Protecting forests safeguards species and habitats that are often threatened by climate shifts.
• Climate regulation - Forests influence local and global weather patterns, helping to stabilise temperatures and rainfall.

Identifying and protecting vulnerable environments

• Assessment of fragility - Governments must pinpoint ecosystems, such as Arctic regions or coral reefs, that are at heightened risk due to temperature changes or extreme weather.
• Protective measures - Strategies may include creating protected areas, restoring degraded landscapes, or implementing sustainable land-use practices to reduce further damage.

Addressing coastal threats due to climate change

Rising sea levels and intensified storms, driven by climate change, pose severe risks to coastal areas through flooding and erosion. Proactive planning is essential to mitigate these threats and protect communities.

Strategies for coastal protection

• Risk identification - Mapping low-lying coastal zones and areas prone to marine erosion to prioritise intervention.
• Defensive infrastructure - Building sea walls, flood barriers, or mangrove buffers to shield against water intrusion and storm surges.
• Relocation planning - In extreme cases, moving vulnerable populations inland to safer areas as a long-term adaptation measure.
• Community preparedness - Educating and equipping coastal residents with resources and plans to respond to flooding events effectively.
