The recent UN report on climate change alerts the world to the dramatic consequences to the environment that increasing global warming trends in our planet pose for our survival. One of these negative consequences is on people’s health, particularly in developing countries that don’t have the financial resources to deal with them.
According to the National Oceanic and Atmospheric Administration 2020 was Earth’s second hottest for the past 140 years. Furthermore, 19 of the warmest years on record have occurred since 2000. There has been a considerable impact of these increasing global warming trends on people of all ages.
Annual deaths as a result of climate change are estimated in 150,000 by the World Health Organization (WHO). Between 2030 and 2050, this number could be as high as 250,000 additional deaths. Most of those deaths will be due to heat stress, and to malnutrition, malaria and intestinal and respiratory infections, particularly in children from developing countries.
Climate change impacts negatively on social and environmental determinants of health such as clean air, safe drinking water, enough food and safe shelter. The direct costs of health conditions (excluding costs in health-determining sectors such as agriculture, water and sanitation) caused or worsened as a result of climate change is considerable. WHO estimates them at $2-4 billion by 2030.
It is possible that climate change may bring some benefits, such as fewer deaths in winter in some climates, as well as increased food production in areas free from the rigors of cold weather. However, an assessment of its consequences shows that most of them are negative.
The WHO reports that globally, the number of weather-related natural disasters has more than tripled since the 1960s. They have resulted in over 60,000 deaths, mainly in developing countries. Natural disasters force people to move, which increases the likelihood of negative health effects such as mental disorders and communicable diseases.
Ever more frequent heat waves increase illnesses and hospitalizations. On July 10, 2021, the third-hottest reliably measured temperature (129.4º F) was recorded at California’s Death Valley. A study commissioned by AARP (American Association of Retired Persons) concludes that hospital admissions and emergency-room visits for kidney failure, urinary tract infections and other health problems increase significantly for older adults during heat waves.
Extremely high temperatures increase ground-level ozone concentrations which can lead to serious respiratory diseases such as asthma, emphysema and chronic obstructive pulmonary disease (COPD). Global warming also increases the number of infectious diseases carried by ticks, mosquitoes and other vectors.
