Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
Though individuals who already had mental ill health, especially psychosis, can need intensive care, which can be challenging to deliver if local mental health services were disrupted by the extreme weather. [1] [14] [19] Physical health can be severely impacted by climate change (see also effects of climate change on human health). The ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Hotter, longer heatwaves Even a small increase in average temperatures makes a big difference to heat extremes. As the range of daily temperatures shifts to warmer levels, hotter days become more ...
More frequent heatwaves in late spring and early summer may affect short-term human adaptation. Heatwaves in early summer now have a greater impact on heat-related morbidity and mortality than later in the same season. This is attributed to the effects of short-term adaptation to thermal conditions through physiological and behavioral adaptations.
The scientific understanding of potential health risks and observed health impacts caused by climate change is now better understood. One category of health risks is that of infectious diseases. A study concluded in 2022 that "58% (that is, 218 out of 375) of infectious diseases confronted by humanity worldwide have been at some point ...
For example, when looking at the effects of climate change on human health, a report published in The Lancet found that the greatest impact tends to fall on the most vulnerable people such as the poor, women, children, the elderly, people with pre-existing health concerns, other minorities and outdoor workers.
Mental health and physical health are largely intertwined, so any climate change-related effects on physical health can directly affect mental health. [22] Environmental disruption, such as the loss of bio-diversity , or even the loss of environmental features like sea-ice , cultural landscapes, or historic heritage can also cause negative ...
