The total economic impacts from climate change are difficult to estimate. In general, they increase the more the global surface temperature increases (see climate change scenarios). Economic analysis also looks at the economics of climate change mitigation. Most types of climate change effects are associated with an economic cost.
Each data point represents an average of simulated values generated from five integrated assessment models. [1] Shared Socioeconomic Pathways ( SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. [2] They are used to derive greenhouse ...
Changes in climate can cause decreasing yields for some crops and regions, resulting in higher food prices, food insecurity, and undernutrition. Climate change can also reduce water security. These factors together can lead to increasing poverty, human migration, violent conflict, and mental health issues. [7] [8] [3]
The climate and health crises are trapping people in a cycle of poverty and despair. Estimates project that 1.2 billion people will be displaced by climate change by 2050. ... Studies have shown ...
However, climate change is likely to affect the health of the most vulnerable in high income countries as well. “These conditions can create or intensify exposures to hazards that impact human health, like extreme heat, poor air quality, reduced food and water quality, and displacement of populations of people,” she tells Medical News Today.
Globally, the benefits of keeping warming under 2 °C exceed the costs. [120] Economists estimate the cost of climate change mitigation at between 1% and 2% of GDP. [121] While this is a large sum, it is still far less than the subsidies governments provide to the ailing fossil fuel industry.
The health benefits from climate change mitigation are significant. Potential measures can not only mitigate future health impacts from climate change but also improve health directly. Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution.
Climate finance is an umbrella term for loans, investments, and other forms of financial capital allocation in the area of climate change mitigation, adaptation and/or resiliency. There are two main sub-categories of climate finance: private and public, and the two can intersect.
