UN report says that health risks related to climate change are on the rise worldwide. At the same time, coordinated international responses can help prevent some of the worst impacts of climate change on health.
Youssef Nassef, Director of the Adaptation Programme of the UNFCCC secretariat, says: “the report clearly highlights the need for the UN and partners to continuously strengthen their actions to support governments to build climate resilience, including measures to protect human health.”
The report will be presented to governments during the next round of climate change negotiations to be held in Bonn from 8-18 May 2017.
It was prepared in collaboration with countries, the World Health Organization and other relevant expert organizations, under the Nairobi work programme − UN Knowledge-for-Action Climate Resilience Network. Below follows an overview of the report’s main findings.
Climate change is expected to exacerbate health problems that already pose a major burden to vulnerable populations
The report shares at least five major insights:
1. Certain groups have higher susceptibility to climate-sensitive health impacts owing to their age (children and elderly), gender (particularly pregnant women), social marginalization (associated in some areas with indigenous populations, poverty or migration status), or other health conditions like HIV. The socioeconomic costs of health problems caused by climate change are considerable.
2. Many infectious diseases, including water-borne ones, are highly sensitive to climate conditions. Figure 1 illustrates the correlation between temperature and diarrhea. A main concern in both developed and developing countries was the increase in and increased geographical spread of diarrhoeal diseases, the report found.
Sensitivity of diarrhoeal disease to meteorological conditions. Source: Checkley W et al. 2000. Effects of El Niño and ambient temperature on hospital admissions for diarrhoeal diseases in Peruvian children. Lancet. 355: pp.442–450. Notes: (1) Section A of the figure shows daily admissions for severe diarrhoea at the main paediatric clinic in Lima; (2) Section B of the figure shows daily variations in temperature for Lima over the same period.
3. Climate change lengthens the transmission season and expands the geographical range of many diseases like malaria and dengue. For example, the conditions for dengue transmission are likely to expand significantly across the globe (see figure 2 below)
Changing patterns of infectious disease: dengue transmission. Source: Based on data from Hales S, de Wet N, Maindonald J and Woodward A. 2002. Potential effect of population and climate changes on global distribution of dengue fever: an empirical model. Lancet. 360: pp.830–834. Notes: (1) Section (a) shows dengue fever transmission in 1990; (2) Section (b) shows projected expanded distribution of dengue fever in the warmer, wetter and more humid conditions expected in the 2080s, assuming no change in non-climatic determinants of dengue distribution.
4. Climate change will bring new and emerging health issues, including heatwaves and other extreme events. Heat stress can make working conditions unbearable and increase the risk of cardiovascular, respiratory and renal diseases. Additionally, it is estimated that 22.5 million people are displaced annually by climate or weather-related disasters, and these figures are expected to increase in the future. Climate-induced human mobility has a socioeconomic cost and can affect mental and physical health.
5. Malnutrition and undernutrition were highlighted as a concern for a number of developing countries in Africa, Asia and Latin America, which discussed the impacts of climate change on food security, particularly in relation to floods and drought.
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events
