[46] Deaths do not just occur from drowning, deaths are connected with dehydration, heat stroke, heart attack and any other illness that needs medical supplies that cannot be delivered. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress. The outbreak of coronavirus disease-2019 (COVID-19) first emerged at the end of December 2019, from the Hunan seafood market in Wuhan City of China, and declared as an international public health emergency in a couple of weeks by the World Health Organization ().It is an infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) (Islam et … [53], The human body requires evaporative cooling to prevent overheating, even with a low activity level. In floods where there are many fatalities in the water there is a hygienic problem with the handling of bodies, due to the panic stricken mode that comes over a town in distress. Rising sea levels cause saltwater to enter into fresh underground water and freshwater streams. A research organization known as Climate Central states “The land area of the U.S. most suitable for Aedes albopictus mosquitoes is projected to increase from 5 percent to about 50 percent by 2100, putting 60 percent of the northeastern U.S.’ population at risk for the diseases carried by this mosquito, including West Nile virus, dengue and Zika.”[16] An outbreak of diseases like the West Nile and Zika virus could trigger a crisis since it would cause severe illness in people as well as birth defects in infants. The major cause of the greenhouse effect is the unlawful and hazardous activities of humans. However, it is important that medicinal resources are managed appropriately as they become globally traded in order to prevent species endangerment. [66] Climate change leads to a warmer ground temperature and its effects include earlier snowmelt dates, drier than expected vegetation, increased number of potential fire days, increased occurrence of summer droughts, and a prolonged dry season.[67]. All populations will be affected by climate change, but some are more vulnerable than others. Transmitted by Anopheles mosquitoes, malaria kills over 400 000 people every year – mainly children under 5 years old in certain African countries. By Robin Bravender on April 17, 2009; Share on Facebook. In Asia, investigations intensified markedly after the 2004 Tsunami. For example, if there is a flash flood it would not matter how prepared you are. The United States Environmental Protection Agency had issued a 100-page report on global warming and human health back in 1989. Addressing climate change requires action from everyone across all nations. There are six greenhouse gases as follows: Carbon dioxide (CO2) Methane (CH4) [17] As flooding increases there is also an increase in cholera epidemics as the flood waters that are carrying the bacteria are infiltrating the drinking water supply. A. Quick changes in temperature and humidity facilitate the spread of diseases. [45] This in turn can lead to a greater risk of flooding due to higher runoff occurring from the removal of potential interception and transpiration from the hydrologic cycle. Malaria is strongly influenced by climate. [90][91][92], Warmer water temperatures also affect water quality and accelerate water pollution.[93]. The human response to heat stress can be hyperthermia, heat stroke and other harmful effects. These include:[104], Studies have found that when communicating climate change with the public, it can help encourage engagement if it is framed as a health concern, rather than as an environmental issue. While drought does indeed greatly impact agricultural production, it also has a large impact on naturally occurring vegetation. Climatic conditions strongly affect water-borne diseases and diseases transmitted through insects, snails or other cold-blooded animals. [68] The primary pollutants in wood smoke are carbon monoxide and nitric oxide. Rising sea levels and increasingly extreme weather events will destroy homes, medical facilities and other essential services. In 2015, the WHO Executive Board endorsed a new work plan on climate change and health. 2013a)—a long-term average increase of 0.06–0.07 °C per decade. Climate change is a natural phenomenon. As of 2020, only two weather stations had recorded 35 °C wet-bulb temperatures, and only very briefly, but the frequency and duration of these events is expected to rise with ongoing climate change. [3], Ticks are also thriving in the warmer temperatures allowing them to feed and grow at a faster rate. Over this time period the cirque and steep alpine glaciers were able to acclimatize to the new temperatures posed by climate change; large valley glaciers have not yet made this adjustment. coastline inhabitants, indigenous peoples, economically disadvantaged communities). Glacial retreat first gained the attention of alpinists and the tourist industry shortly after 1940 – when the globe warmed ~0.5 °C. The potential exists for climate change and variability to have a major impact on the frequency of severe droughts. [3][5] Extreme weather also means stronger winds. [61] Heat waves have also resulted in epidemics of chronic kidney disease (CKD). Health Effects The key effects that support EPA’s determination that current and future concentrations of greenhouse gases endanger public health include: Temperature There is evidence that the number of extremely hot days is already increasing. There is evidence that emotional responses to climate change can be adaptive if individuals have the capacity and support to reflect on and process the complexity of their emotions. More than half of the world's population lives within 60 km of the sea. The Countries with lower incomes are more likely to have more fatalities, because of the lack of resources they have and the supplies to prepare for a flood. Organisms, such as shellfish, marine crustaceans and even fish, feed on or near these infected blooms, ingest the toxins and can be consumed unknowingly by humans. [67] Through the destruction of forests and human-designed infrastructure, wildfire smoke releases other toxic and carcinogenic compounds, such as formaldehyde and hydrocarbons. Fungal contamination in homes is associated with increased allergic rhinitis and asthma. [53] Some research indicate that climate change has already had negative effects on air quality. The warming oceans are becoming a breeding ground for toxic algae blooms (also known as red tides) and cholera. The effects of heatwaves on human health are generally worse in urban areas, due to the "heat island" effect. Infectious diseases whose transmission can be impacted by climate change include dengue fever, malaria, tick-borne disease, leishmaniasis, ebola. [3][4] These extreme weather patterns are creating extended rainy seasons in some areas,[5] and extended periods of drought in others,[6] as well as introducing new climates to different regions. The heat island effect is when urban areas experience much higher temperatures that surrounding rural environments. Higher temperatures drive more thunderstorms and increase the frequency and severity of forest fires. [101] Absent effective efforts to adapt, the health impact of climate change is expected to rise in line with predicted ongoing global warming. The direct and indirect effects of climate change on human health are becoming increasingly obvious. [33], According to the United Nations Environment Programme the Coronavirus disease 2019 is zoonotic, e.g., the virus passed from animals to humans. Reducing emissions of greenhouse gases through better transport, food and energy-use choices can result in improved health, particularly through reduced air pollution. [86] Local knowledge surrounding medicinal plants is useful for screening for new herbal medicines that may be useful for treating disease. During floods accidents occur with falling debris or any of the many fast moving objects in the water. Such increases in carbon and nitrogen sequestration can help mitigate greenhouse gas emission effects. [17][18], Warmer freshwater is increasing the presence of the amoeba Naegleria fowleri, in freshwater and the parasite Cryptosporidium in pools, and both can cause a severe disease. [22] Models suggest, conservatively, that risk of malaria will increase 5–15% by 2100 due to climate change. Given the current climate change trends, fire seasons are expected to become longer, fire weather is expected to become more severe, and the area burned and amount of fires will increase. Greenhouse gases up to a certain level are relatively harmless. [46], Communicable diseases are increased due to many pathogens and bacteria that are being transported by the water. Thanks to its release by many human activities, carbon dioxide (CO 2) is one of the most notorious of these planet-warming gases, but water vapor is a strong greenhouse … Other health related effects arise from environmental degradation, diseases carried by vectors, food and waterborne infections, changes to food security, and impacts on mental health. Generally, greenhouse gases are harmless. Introduction. Less advanced countries would be especially affected as they may have very limited resources to combat an infestation. [99][100] By the early years of the 21st century, climate change was increasingly addressed as a public health concern at a global level, for example in 2006 at Nairobi by UN secretary general Kofi Annan. The United Nations Environment Programme concludes that: "The most fundamental way to protect ourselves from zoonotic diseases is to prevent destruction of nature. [56] The recession of glaciers change sea salt, sediment, and temperature ratios in the ocean which changes currents, weather patterns, and marine life. … Climate change does not impact everyone equally; those of lower economic and social status are at greater risk and experience more devastating impacts. [46], Another result of the warming oceans are stronger hurricanes, which will wreak more havoc on land, and in the oceans,[54] and create more opportunities for vectors to breed and infectious diseases to flourish. [51], Mortalities are not uncommon when it comes to floods. Injuries are not isolated to just those who were directly in the flood, rescue teams and even people delivering supplies can sustain an injury. This is again a clear indication of the fact why greenhouse is quite a concern for students these days. [3][10][17] As the nitrogen and phosphorus levels in the oceans increase, the cholera bacteria that lives within zooplankton emerge from their dormant state. Severe heat waves Currently, 1/6 of the global population are without adequate food supply. This means that even a relatively short, mild drought may cause enormous damage- even though the drought on its own may not be enough to kill a significant portion of the crops, once the plants become weakened, they are at higher risk of becoming infested. Many policies and individual choices have the potential to reduce greenhouse gas emissions and produce major health co-benefits. Long-term exposure to ozone has been found to promote inflammation, impair pulmonary function, increase the risk of death from respiratory causes. The growing concentrations of human-generated GHGs have resulted in an increased absorption, largely in the lower atmosphere, of the heat radiated from Earth’s surface, causing an increase in the global (land and ocean) mean surface temperature of 0.85 ± 0.20 °C from 1880 to 2012 (Stocker et al. “Sea level rise will cause a change of state from freshwater to marine or estuarine ecosystems, radically altering the composition of biotic communities". [3], In 2016 the United Nations Environment Programme published the "UNEP FRONTIERS 2016 REPORT". It O3 induces airway inflammation and increased airway permeability, while decreasing lung function. It also mentioned how every 4 months a new disease is discovered in humans, and that as of 2016, outbreaks have cost lives and financial losses amounting to billions dollars; future pandemics could cost trillions of dollars. [96], Due to its significant impact on human health,[97][98] climate change has become a major concern for public health policy. [55] Today this is clearly not the case as global warming is causing mountain snow lines to rapidly retreat. [75][76] The Clayton study claims that in order to appreciate these impacts on psychological wellbeing, one must recognize the different cultural narratives associated with climate change, as well as how climate change and global phenomena like increased population, are interrelated. [70] Because wildfire smoke travels and is often not isolated to a single geographic region, the health effects are widespread among populations. The health effects of climate change are increasingly a matter of concern for the international public health policy community. These greenhouse gases are used in aerosol cans and refrigeration. [53] Vector borne diseases increase as well due to the increase in still water after the floods have settled. According to the authors, this may cut humans' basic decision-making ability indoors by ~25% and complex strategic thinking by ~50%. Sea levels are rising, glaciers are melting and precipitation patterns are changing. Immune function decreases, so mortality rates due to infectious and other diseases climb. Warming spring and summer temperatures increase flammability of materials that make up the forest floors. [30][31] Dengue fever is spread by the bite of the female mosquito known as Aedes aegypti. "Projecting the Impact of Climate Change on Dengue Transmission in Dhaka, Bangladesh". The direct damage costs to health (i.e. [23] In Africa alone, according to the MARA Project (Mapping Malaria Risk in Africa),[24] there is a projected increase of 16–28% in person-month exposures to malaria by 2100. [62] These cases are occurring across the world congruently with heat stress nephropathy. Both the Clayton study and the Berry study identify three classes of psychological impacts from global climate change: direct, indirect, and psychosocial. [6] These extended seasons are creating climates that are able to sustain disease vectors for longer periods of time, allowing them to multiply rapidly, and also creating climates that are allowing the introduction and survival of new vectors. However, the current phase of climate change being experienced is being accelerated by human activities that result in the emission of greenhouse gases. [7], Mosquito-borne diseases are probably the greatest threat to humans as they include malaria, elephantiasis, Rift Valley fever, yellow fever, and dengue fever. In the last 130 years, the world has warmed by approximately 0.85oC. [87] Formal scientific methods have been useful in identifying the active ingredients used in ethnopharmacy and applying them to modern medicines.
