Climate change causing tens of thousands deaths every year: WHO
Nov 18, NY: With the United Nations climate conference (COP21) starting in Paris in less than two weeks later, the World Health Organization (WHO) on Wednesday underlined that climate change is already causing tens of thousands of deaths every year, and called on countries to take strong measures to address the issue.
The UN health agency is attributing these deaths to shifting patterns of disease from extreme weather events – such as heat-waves and floods – and from the degradation of air quality, food and water supplies, and sanitation.
“The upcoming United Nations climate change conference (COP21) in Paris offers the world an important opportunity to not only reach a strong international climate agreement, but also to protect the health of current and future generations,” WHO said in a press release, adding that the agreement would have the potential to save lives worldwide.
In 2012, the agency estimated seven million people died from air pollution-related diseases, making it the world’s largest single environmental health risk. It is predicted that climate change will cause an additional 25 000 deaths per year from malaria, diarrhea, heat stress and under-nutrition between 2030 and 2050. Children, women and the poor in lower income countries will reportedly be the most vulnerable and most affected, widening health gaps.
Highlighting that not only are ways to combat climate change already known and well-documented, WHO said they can bring important health gains. As its new series of climate change and health country profiles illustrate, investments in low-carbon development, clean renewable energy, and strengthening climate resilience, are also investments in health.
“Implementing proven interventions to reduce emissions of short-lived climate pollutants, like black carbon and methane, for example achieving higher vehicle emissions and efficiency standards, would be expected to save approximately 2.4 million lives a year and reduce global warming by about 0.5°C by 2050,” the agency reported.
In addition, placing a price on polluting fuels to compensate their negative health impacts would be expected to cut outdoor air pollution deaths by half, reduce carbon dioxide emissions by more than 20 per cent, and raise approximately US$ 3 trillion per year in revenue – over half the total value of health spending by all of the world’s governments.
WHO is also insisting that strengthening health resilience to climate risks, including measures such as early-warning systems for more frequent and severe heatwaves, and protection of water, sanitation, and hygiene services against floods and droughts, would ensure that recent progress against climate-sensitive diseases, is not slowed or reversed.
In preparation for COP21, formally the 21st Meeting of the States Parties to the UN Framework Convention on Climate Change (UNFCCC), WHO indicated that countries have made important commitments to cut greenhouse gas emissions and scale up adaptation to climate change, but more needs to be done.
