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 ...
The most negative impacts of drought for humans include crop failure, food crisis, famine, malnutrition, and poverty, which lead to loss of life and mass migration of people. [27] There are negative effects on the health of people who are directly exposed to this phenomenon (excessive heat waves).
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 ...
About 77% of the mainland U.S. is abnormally dry, and almost half of the country is experiencing drought, according to the U.S. Drought Monitor. The spatial pattern of the dry conditions varies ...
Since 2000, climate change has been the primary cause of both the expansion of the drought area and the increase in drought severity, with that percentage rising to over 90% during the drought period.
In later decades, practices such as crop rotation, intercropping, and agroforestry have been advocated to enhance soil health and water retention, which are critical under drought conditions. [ 2 ] [ 20 ] These approaches enhance overall ecosystem health, reducing the likelihood of future agricultural crises stemming from environmental degradation.
Other solutions include increasing access to quality health care for poor people and people of color, preparedness planning for urban heat island effects, identifying neighborhoods that are most likely to be impacted, investing in alternative fuel and energy research, and measuring the results of policy impacts.
