The IPCC Report “ Climate Change 2014”, The Summary for Decision Makers
Abstract
Climate change refers to long-term changes in the Earth's climate, including changes in temperature, precipitation, and weather patterns, that are primarily caused by human activities such as burning fossil fuels, deforestation, and other industrial activities. These activities release large amounts of greenhouse gases, such as carbon dioxide and methane, into the atmosphere, which trap heat and lead to a warming of the planet's surface. The effects of climate change are wide-ranging and include rising sea levels, more frequent and severe heat waves, droughts, floods, storms, and other extreme weather events, as well as negative impacts on biodiversity, agriculture, human health, and infrastructure. Climate change is a pressing global issue that requires immediate action to mitigate its impacts and adapt to its effects.
The IPCC's Summary for Policymakers from the Fifth Assessment Report on Climate Change (AR5) provides a concise overview of the key findings from the three working group reports that make up the AR5. The report assesses the current state of knowledge about climate change and its impacts, as well as options for mitigating greenhouse gas emissions and adapting to the changing climate. The Summary for Policymakers is organized into sections that cover topics such as observed changes in the climate system, future projections of climate change, impacts on natural and human systems, and potential responses to reduce emissions and adapt to the impacts of climate change. It also highlights key risks and uncertainties associated with different levels of global warming and emphasizes the importance of limiting greenhouse gas emissions to avoid the most severe impacts of climate change. Overall, the Summary for Policymakers aims to provide policymakers, stakeholders, and the public with a clear and accessible summary of the latest scientific knowledge on climate change and its impacts, as well as options for action.
The IPCC
The IPCC stands for the Intergovernmental Panel on Climate Change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide a scientific assessment of the risks of climate change caused by human activities. The IPCC is a leading international body for the assessment of climate change, bringing together thousands of scientists and experts from around the world to review and synthesize the latest research on climate change and its impacts.
The IPCC's main role is to assess and report on the state of knowledge about climate change, its impacts, and options for mitigating and adapting to it. It produces a series of comprehensive Assessment Reports every few years, which synthesize the latest scientific, technical, and socio-economic information about climate change. The IPCC's reports are used by policymakers, governments, and other stakeholders to inform decisions related to climate change mitigation, adaptation, and policy.
Climate Change Vulnerabilities for Taiwan
The IPCC's Fifth Assessment Report (AR5) identifies a range of climate change vulnerabilities for Taiwan, including:
i. Sea level rise
Taiwan is particularly vulnerable to sea level rise due to its long coastline, high population density in low-lying coastal areas, and frequent extreme weather events. Rising sea levels could lead to increased coastal erosion, flooding, and damage to infrastructure, buildings, and agricultural land.
ii. Extreme weather events
Taiwan is already prone to typhoons, heavy rainfall, and floods, which are expected to become more frequent and severe under climate change. These events can cause widespread damage to infrastructure, homes, and crops, as well as lead to loss of life and displacement of people.
iii. Water scarcity
Taiwan is already experiencing water scarcity in some regions, and climate change is expected to exacerbate this issue by altering rainfall patterns and increasing evaporation rates. This could lead to reduced water availability for agriculture and industry use.
iv. Biodiversity loss
Taiwan is home to a unique and diverse range of plant and animal species, but climate change is expected to put many of these species at risk. Changes in temperature, precipitation, and extreme weather events could alter ecosystems and lead to species loss and extinction.
v. Health impacts
Climate change is expected to increase the frequency and intensity of heatwaves and other extreme weather events, which can lead to heat-related illnesses, respiratory problems, and other health impacts. Vulnerable populations, such as the elderly, young children, and people with pre-existing health conditions, are particularly at risk.
Overall, I reckon that the IPCC's AR5 highlights the need for Taiwan to take action to reduce greenhouse gas emissions and adapt to the impacts of climate change to reduce its vulnerabilities and build resilience. It is not surprising that Taiwan is vulnerable to these impacts of climate change. As mentioned, Taiwan is a small island nation located in a region that is highly susceptible to extreme weather events, such as typhoons, heavy rainfall, and flooding. In addition, Taiwan's densely populated coastal areas, combined with the potential for sea level rise, make it particularly vulnerable to the impacts of climate change. Furthermore, the IPCC's reports are based on a comprehensive and rigorous scientific assessment process involving thousands of scientists from around the world. The vulnerabilities identified for Taiwan in the IPCC's Fifth Assessment Report are based on the best available scientific evidence and are supported by a high degree of scientific consensus.
Addressing Climate Change Issues
Taiwan has proposed and implemented various adaptation measures to address the impacts of global climate change:
i. Coastal protection
Taiwan has implemented a range of measures to protect its coastline from sea level rise and increased storm surge, such as building sea walls, dikes, and artificial reefs. Taiwan has also developed a system of early warning and evacuation for coastal areas during typhoons and other extreme weather events(Lin & Lee, 2020).
ii. Water management
Taiwan has implemented measures to improve water management, including developing new water sources, improving water use efficiency, and promoting water conservation. Taiwan has also developed plans for drought management and has implemented measures to prevent flooding and landslides in mountainous areas(Lin & Lee, 2020).
iii. Agriculture
Taiwan has developed new varieties of crops that are more resilient to drought and other extreme weather conditions(Lin & Lee, 2020). Taiwan has also implemented measures to improve soil quality and promote sustainable agriculture practices.
iv. Health
Taiwan has developed a heat health warning system to reduce the impacts of heatwaves on public health. Taiwan has also implemented measures to reduce air pollution, such as promoting public transportation and using cleaner energy sources.
v. Infrastructure
Taiwan has implemented measures to improve the resilience of its infrastructure to the impacts of climate change, such as designing buildings and bridges to withstand extreme weather events and earthquakes.
Overall, Taiwan has taken a proactive approach to address the impacts of climate change by developing and implementing adaptation measures across multiple sectors. However, continued efforts and investment are needed to ensure that Taiwan can build resilience to the impacts of climate change and maintain sustainable development. In addition, it is difficult to say which of the adaptation measures proposed for addressing global climate change in Taiwan is the most important, as all of these measures are important and interrelated. Each measure serves a specific purpose and contributes to building resilience to the impacts of climate change in different ways. I believe a comprehensive and integrated approach to adaptation is necessary, which includes a combination of measures across multiple sectors. The effectiveness of each measure depends on the specific context and needs of the community or region it serves.
I believe that the greatest threat to our planet or any planet, is the belief that someone else will save it. Let’s take at least one step to lower the climate impacts and save our home. Yes, it is also your home and you can save it.
- You can shift to renewable energy sources, such as solar or wind power, by installing solar panels, purchasing renewable energy from utility companies, or using community solar programs (Union of Concerned Scientists, 2021).
- You can reduce transportation emissions by using public transit, biking, or walking instead of driving alone, driving a fuel-efficient vehicle, or shifting to electric vehicles (Union of Concerned Scientists, 2021).
- You can reduce meat consumption and shift to a plant-based diet, as meat production has a high carbon footprint due to land use changes, emissions from animal waste, and other factors (Union of Concerned Scientists, 2021).
- You can reduce waste by recycling, composting, and reducing consumption of single-use products (Union of Concerned Scientists, 2021).
