Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue fever, malaria, tick-borne diseases, leishmaniasis, zika fever, chikungunya and Ebola. One mechanism contributing to increased disease transmission is that climate change is altering the geographic range and seasonality ...
Climate change threatens people with increased flooding, extreme heat, increased food and water scarcity, more disease, and economic loss. Human migration and conflict can also be a result. [12] The World Health Organization calls climate change one of the biggest threats to global health in the 21st century. [13]
As global climate has changed progressively over the past several decades, it has collided with environmental racism.The overlap of these two phenomena, has disproportionately affected different communities and populations throughout the world due to disparities in socio-economic status.
Climate change feedbacks are natural processes that impact how much global temperatures will increase for a given amount of greenhouse gas emissions. Positive feedbacks amplify global warming while negative feedbacks diminish it. [2]: 2233 Feedbacks influence both the amount of greenhouse gases in the atmosphere and the amount of temperature ...
Future global warming potential for long lived drivers like carbon dioxide emissions is not represented. The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre ...
Climate change can also reduce access to clean and safe water supply. Extreme weather and its health impact can also threaten the livelihoods and economic stability of people. These factors together can lead to increasing poverty, human migration, violent conflict, and mental health issues. [7][8]
The scientific consensus regarding causes and mechanisms of climate change, its effects and what should be done about it (climate action) is that: It is "unequivocal" and "incontrovertible" that the greenhouse gas emissions from human activities have caused warming on land, in oceans and in the troposphere.
An economic analysis of climate change uses economic tools and models to calculate the magnitude and distribution of damages caused by climate change. It can also give guidance for the best policies for mitigation and adaptation to climate change from an economic perspective. There are many economic models and frameworks.
