Climate Change Vulnerability
Climate change vulnerability (or climate vulnerability or climate risk vulnerability ) is an assessment of vulnerability to climate change used in discussion of society's response to climate change, for processes like climate change adaptation, evaluations of climate risk or in determining climate justice concerns. Climate vulnerability can include a wide variety of different meanings, situations and contexts in climate change research, but has been a central concept in academic research since 2005. The concept was defined in the third IPCC report as "the degree to which a system is susceptible to, and unable to cope with, adverse effects of climate change, including climate variability and extremes".:89
Vulnerability can mainly be broken down into two major categories, economic vulnerability, based on socioeconomic factors, and geographic vulnerability. Neither are mutually exclusive. In line with system-level approach to vulnerability in the International Panel on Climate Change (IPCC), most scholarship uses climate vulnerability to describe communities, economic systems or geographies. However, the widespread impacts of climate change have led to the use of "climate vulnerability" to describe less systemic concerns, such as individual health vulnerability, vulnerable situations or other applications beyond impacted systems, such as describing the vulnerability of individual animal species. There are several organizations and tools used by the international community and scientists to assess climate vulnerability.
Negative impacts of climate change are those that are least capable of developing robust and comprehensive climate resiliency infrastructure and response systems. However what exactly constitutes a vulnerable community is still open to debate. The IPCC has defined vulnerability using three characteristics: the "adaptive capacity, sensitivity, and exposure" to the effects of climate change. The adaptive capacity refers to a community's capacity to create resiliency infrastructure, while the sensitivity and exposure elements are both tied to economic and geographic elements that vary widely in differing communities. There are, however, many commonalities between vulnerable communities.

At its basic level, a community that is economically vulnerable is one that is ill-prepared for the effects of climate change because it lacks the needed financial resources. Preparing a climate resilient society will require huge[quantify] investments in infrastructure, city planning, engineering sustainable energy sources, and preparedness systems.[clarification needed] From a global perspective, it is more likely that people living at or below poverty will be affected the most by climate change and are thus the most vulnerable, because they will have the least amount of resource dollars to invest in resiliency infrastructure. They will also have the least amount of resource dollars for cleanup efforts after more frequently occurring natural climate change related disasters.
A second definition of vulnerability relates to geographic vulnerability. The most geographically vulnerable locations to climate change are those that will be impacted by side effects of natural hazards, such as rising sea levels and by dramatic changes in ecosystem services, including access to food. Island nations are usually noted as more vulnerable but communities that rely heavily on a sustenance based lifestyle are also at greater risk.

Vulnerable communities tend to have one or more of these characteristics:
delicate marine ecosystem
small island community
Around the world, climate change affects rural communities that heavily depend on their agriculture and natural resources for their livelihood. Increased frequency and severity of climate events disproportionately affects women, rural, dryland, and island communities. This leads to more drastic changes in their lifestyles and forces them to adapt to this change. It is becoming more important for local and government agencies to create strategies to react to change and adapt infrastructure to meet the needs of those impacted. Various organizations work to create adaptation, mitigation, and resilience plans that will help rural and at risk communities around the world that depend on the earth's resources to survive.
Differences by region or sector
Vulnerability is often framed in dialogue with climate adaptation. IPCC (2007a) defined adaptation (to climate change) as "[initiatives] and measures to reduce the vulnerability of natural and human systems against actual or expected climate change effects" (p. 76). Vulnerability (to climate change) was defined as "the degree to which a system is susceptible to, and unable to cope with, adverse effects of climate change, including climate variability and extremes" (p. 89). Different communities or systems are better prepared for adaptation in part because of their existing vulnerabilities.
With high confidence, researchers concluded in 2001 that developing countries would tend to be more vulnerable to climate change than developed countries.:957-958 Based on then-current development trends, it was predicted that few developing countries would have the capacity to efficiently adapt to climate change. :940-941
Africa: Africa's major economic sectors have been vulnerable to observed climate variability.:435 This vulnerability was judged to have contributed to Africa's weak adaptive capacity, resulting in Africa having high vulnerability to future climate change. It was thought likely that projected sea-level rise would increase the socio-economic vulnerability of African coastal cities.
Asia: Climate change is expected to result in the degradation of permafrost in boreal Asia, worsening the vulnerability of climate-dependent sectors, and affecting the region's economy.:536
Australia and New Zealand: In Australia and New Zealand, most human systems have considerable adaptive capacity. However, some Indigenous communities were judged to have low adaptive capacity.:509
Europe: The adaptation potential of socioeconomic systems in Europe is relatively high.:643 This was attributed to Europe's high GNP, stable growth, stable population, and well-developed political, institutional, and technological support systems.
Latin America: The adaptive capacity of socioeconomic systems in Latin America is very low, particularly in regard to extreme weather events, and that the region's vulnerability was high.:697
Polar regions: A study in 2001 concluded that::804-805
within the Antarctic and Arctic, at localities where water was close to melting point, socioeconomic systems are particularly vulnerable to climate change.
the Arctic is extremely vulnerable to climate change. It is predicted that there will be major ecological, sociological, and economic impacts in the region.
Small islands: Small islands are particularly vulnerable to climate change.:689 Partly this was attributed to their low adaptive capacity and the high costs of adaptation in proportion to their GDP.
Systems and sectors
Coasts and low-lying areas: Societal vulnerability to climate change is largely dependent on development status.:336 Developing countries lack the necessary financial resources to relocate those living in low-lying coastal zones, making them more vulnerable to climate change than developed countries. On vulnerable coasts, the costs of adapting to climate change are lower than the potential damage costs.:317
Industry, settlements and society:
At the scale of a large nation or region, at least in most industrialized economies, the economic value of sectors with low vulnerability to climate change greatly exceeds that of sectors with high vulnerability.:336 Additionally, the capacity of a large, complex economy to absorb climate-related impacts, is often considerable. Consequently, estimates of the aggregate damages of climate change - ignoring possible abrupt climate change - are often rather small as a percentage of economic production. On the other hand, at smaller scales, e.g., for a small country, sectors and societies might be highly vulnerable to climate change. Potential climate change impacts might therefore amount to very severe damages.
Vulnerability to climate change depends considerably on specific geographic, sectoral and social contexts. These vulnerabilities are not reliably estimated by large-scale aggregate modelling.:359
Climate change highly influences health, economy, and human rights which affects environmental inequities. The Intergovernmental Panel on Climate Change (IPCC) Fourth National Climate Assessment Report found that low-income individuals and communities are more exposed to environmental hazards and pollution and have a harder time recovering from the impacts of climate change. For example, it takes longer for low-income communities to be rebuilt after natural disasters. According to the United Nations Development Programme, developing countries suffer 99% of the casualties attributable to climate change.
The majority of the world's biodiversity is located within Indigenous territories. There are over 370 million indigenous peoples found across 90+ countries. Approximately 22% of the planet's land is Indigenous territories, with this figure varying slightly depending on how both Indigeneity and land-use are defined.Indigenous peoples play a crucial role as the main knowledge keepers within their communities. This knowledge includes that which relates to the maintenance of social-ecological systems. The United Nations Declaration on the Rights of Indigenous People recognizes that Indigenous people have specific knowledge, traditional practices, and cultural customs that can contribute to the proper and sustainable management of ecological resources.
Climate change increases gender inequality, reduces women's ability to be financially independent, and has an overall negative impact on the social and political rights of women, especially in economies that are heavily based on agriculture. In many cases, gender inequality means that women are more vulnerable to the negative effects of climate change. This is due to gender roles, particularly in the developing world, which means that women are often dependent on the natural environment for subsistence and income. By further limiting women's already constrained access to physical, social, political, and fiscal resources, climate change often burdens women more than men and can magnify existing gender inequality.
Climate vulnerability can be analyzed or evaluating using a number of processes or tools. Below are several of them. There are several organizations and tools used by the international community and scientists to assess climate vulnerability.
Vulnerability assessments are done for local communities to evaluate where and how communities or systems will be vulnerable to climate change. These kinds of reports can vary widely in scope and scale-- for example the World Bank and Ministry of Economy of Fiji commissioned a report for the whole country in 2017-18 while the Rochester, New York commissioned a much more local report for the city in 2018. Or, for example, NOAA Fisheries commissioned Climate Vulnerability assessments for marine fishers in the United States.
Vulnerability assessments in Global south
In the Global South, the vulnerability assessment is usually developed during the process of preparing local adaptation plans for climate change or sustainable action plans. The vulnerability is ascertained on an urban district or neighborhood scale. Vulnerability is also a determinant of risk and is consequently ascertained each time a risk assessment is required. In these cases, the vulnerability is expressed by an index, made up of indicators. The information that allows to measure the single indicators are already available in statistics and thematic maps, or are collected through interviews. The latter case is used on very limited territorial areas (a city, a municipality, the communities of a district). It is therefore an occasional assessment aimed at a specific event: a project, a plan.
The report distills leading science and research for a clearer explanation of how and where populations are being affected by climate change today (2010) and in the near future (2030), while pointing to key actions that reduce these impacts.
A systematic review published in 2019 found 84 studies focused on the use of mapping to communicate and do analysis of climate vulnerability.
Climate vulnerability tracking starts identifying the relevant information, preferably open access, produced by state or international bodies at the scale of interest. Then a further effort to make the vulnerability information freely accessible to all development actors is required. Vulnerability tracking has many applications. It constitutes an indicator for the monitoring and evaluation of programs and projects for resilience and adaptation to climate change. Vulnerability tracking is also a decision making tool in regional and national adaptation policies.
Because climate vulnerability disproportionally effects countries without the economic or infrastructure of more developed countries, climate vulnerability has become an important tool in international negotiations about climate change adaptation, climate finance and other international policy making activities.
Climate Vulnerable Forum
The Climate Vulnerable Forum (CVF) is a global partnership of countries that are disproportionately affected by the consequences of global warming. The forum addresses the negative effects of global warming as a result of heightened socioeconomic and environmental vulnerabilities. These countries actively seek a firm and urgent resolution to the current intensification of climate change, domestically and internationally.
The CVF was formed to increase the accountability of industrialized nations for the consequences of global climate change. It also aims to exert additional pressure for action to tackle the challenge, which includes local action by countries considered susceptible. Political leaders involved in this partnership are "using their status as those most vulnerable to climate change to punch far above their weight at the negotiating table". The governments which founded the CVF agree to national commitments to pursue low-carbon development and carbon neutrality.
Ethiopia became the first African Chair of the Climate Vulnerable Forum during the CVF High-Level Climate Policy Forum held in the Senate of the Philippines in August 2016.
