The effects of climate change on human health, or becoming increasingly evident.
Extreme weather events are becoming more frequent, more severe, and expensive.
In 2024, there were 27 extreme weather events.
The year 2024, the hottest ever recorded, is accompanied by elevated global sea surface temperature, which is the temperature of ocean water close to the surface.
Climate sensitive outcomes are related to extreme weather and climate events, heat stress, air quality, water quality and quantity, food supply quality and safety, vector distribution and ecology, and social factors driving conflict and migration.
Many client sensitive health outcomes cannot be adequately quantified and include: drowning, intentional violence, occupational injuries, and micronutritional deficiencies
Extreme weather events, such as ice storms, and tornadoes, heat, waves, floods, and wildfires cause increased traumatic human injuries, diseases, deaths, and mental health consequences.
Changes in climate are associated with migration of animals and insects that carry disease.
Changes in the mean temperature, precipitation, sea level, cause increase food and water insecurity, prevalence of aeroallergens inducing, respiratory disease, and the prevalence of many infectious diseases.
Climate change affects sinonasal health directly by increasing aeroallergens and indirectly by changing weather paterns that result in drought related dust, increased concentrations and stasis of air pollutants, worsening of wildfires, and he induced increases in ground level ozone.
The frequency, duration, and intensity of heat waves have increased in recent decades, with the number of annual heat waves twice that of the 1980s, and heat wave season is more than three times as long as it was in the 1960s.
While heat extremes have increased in frequency and duration, cold extremes, have decreased.
Climate change results in emergence of types of infections that vary by geographic area, not previously known to be associated with these infectious agents.
Algal blooms cause nutrient pollution, promote rapid organism growth, reduced water, flow, and ocean acidification.
Algal blooms develop when phytoplankton proliferate in warm, nutrient rich waters, disrupting ecosystems, consuming and depleting oxygen, and producing potent toxins that can negatively affect the human health.
Harmful algal blooms are increasing in frequency and severity, and contribute to diseases such as ciguatera and paralytic or neurotoxic shellfish poisoning and may be more common in patients with pre-existing medical conditions.
The southeastern US coast is affected by neurotoxic shellfish poisoning caused by Karenia brevis responsible for the red tide.
Increased populations of gram-negative cyanobacteria occur in freshwater bodies contaminated with agricultural fertilizers, manure, or urban stormwater;repeated intake and digestion of cyanotoxins through consumption of contaminated fish may be associated with neurodegenerative diseases.
Heavy rains, intensified by climate change, contaminate bivalve cultivation – muscles, oysters, and clams.
Climate change can adversely affect mental health by forced human migration, or threatened livelihood.
Climate change has led to changes in the incidence and treatment of human diseases and their prevention.
Older age underlying health status, access to cooling, living in marginalized neighborhoods, socioeconomic status, and other factors influence the risk of mortality associated with weather pattern changes.
Climate change can contribute to displacement and migration of peoples, with negative effects on health and well-being.
Climate related has its can precipitate adverse events: stagnant water can be a breeding ground for mosquitoes that carry viruses and pathogens.
Increasing temperatures compromising air quality are common health risks associated with climate change.
Affected individuals include patients who are older, those were underlying medical conditions, those taking specific medications, people who are pregnant, and infant and young children.
People with overall exposure that is increased adverse, ambient conditions such as those with inadequate, housing, construction, and agricultural workers are disproportionally affected.
Approximately 8.5% of carbon emissions come from healthcare system, with hospitals contributing approximately 36% of all healthcare carbon emissions.
