Extended Knowledge
Causes and Impacts of Climate Change
The causes and effects of climate change are a complex and wide-ranging topic, so here's a brief look at some basic information:
Causes:
Greenhouse gas emissions: Human activities have led to the emission of large quantities of greenhouse gases, mainly carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), etc. These gases form a "greenhouse effect" in the atmosphere, causing the surface temperature of the Earth to rise. These gases create a "greenhouse effect" in the atmosphere, causing the surface temperature of the Earth to rise.
Fossil fuel use: Burning fossil fuels such as coal, oil and natural gas releases large amounts of carbon dioxide. This is one of the main sources of greenhouse gas emissions.
Deforestation: Forests are one of the most important absorbers of carbon dioxide on the planet, but large-scale deforestation has led to the release of carbon dioxide, destroying the absorptive capacity of forests.
Industrial activities: energy use and emissions from industrial processes are also important sources of greenhouse gases.
Impact:
Increased Climate Extreme Events: Climate change has led to more frequent and severe extreme weather events such as heavy rainfall, droughts, hurricanes and floods. These events have serious impacts on human life, agriculture, infrastructure and ecosystems.
Sea level rise: Global warming is leading to the melting of glaciers and polar ice, which in turn is leading to a rise in sea level. This will threaten coastal populations and ecosystems and increase the risk of marine erosion and flooding.
Loss of biodiversity: Climate change puts pressure on ecosystems, leading to species extinction and loss of biodiversity. Many plants and animals will not be able to adapt to the rapidly changing climatic conditions and the ecological balance will be disrupted.
Threats to agriculture and food security: Climate change threatens food security and farmers' livelihoods through its impacts on crop growing seasons, water resources and agricultural pests and diseases.
Increased health risks: Climate change contributes to air pollution, the spread of disease and problems with drinking water supplies. Extreme heat waves and natural disasters will also have a direct impact on human health.
These are just a few of the causes and effects of climate change, which are intertwined and have far-reaching implications for our planet and our own lives. Understanding and responding to the issue of climate change has therefore become particularly important.
Actions Taken by the International Community to Mitigate Climate Change
Actions taken by the international community to mitigate climate change include the following key aspects:
Paris Agreement: The Paris Agreement is a major international climate change agreement adopted by the United Nations in 2015. The agreement aims to control global warming through global cooperation to limit the increase in global average temperature to 1.5 degrees Celsius and to take action to reduce greenhouse gas emissions. Countries voluntarily submit emission reduction targets and regularly report their progress to the United Nations.
Greenhouse gas emission reduction commitments: Many countries have adopted specific emission reduction commitments. Among them, some countries have committed to achieving carbon neutrality, i.e., reducing their greenhouse gas emissions to zero or balancing emissions with absorption at a specific time. Some countries have also set specific emission reduction targets and policies to promote the development of renewable energy, improve energy efficiency and facilitate the clean energy transition.
Renewable energy promotion: The international community has encouraged and supported the development and application of renewable energy sources, such as solar, wind and hydro energy. Many countries have adopted policies and measures to promote the use of renewable energy by reducing dependence on fossil fuels in order to reduce greenhouse gas emissions.
International cooperation and technology transfer: Countries are engaged in extensive cooperation and technology transfer in mitigating climate change. Developed countries provide financial, technological and capacity-building support to developing countries to help them address the challenges of climate change and achieve sustainable development.
Advancing the sustainable development agenda: The sustainable development agenda is the United Nations global development framework aimed at achieving economic, social and environmental sustainability. Climate change mitigation is one of the sustainable development goals, and countries have been active in advancing the sustainable development agenda by taking actions to achieve the twin goals of climate change and sustainable development.
These actions represent the efforts and cooperation of the international community in mitigating climate change. However, in the face of the challenges of climate change, there is still a need to further strengthen international cooperation and to take more active and vigorous action in order to achieve a sustainable future for the global climate.
