Global Warming Responsible For One In Three Heat-Related Deaths, Study Affirms

The estimates show that 37 per cent of all heat-related deaths in the recent summer periods were attributable to the warming of the planet due to anthropogenic activities

Global Warming Responsible For One In Three Heat-Related Deaths, Study Affirms

London: Between 1991 and 2018, more than a third of all deaths in which heat played a role were attributable to human-induced global warming, according to a new article in the journal Nature Climate Change. The study, the largest of its kind, was led by the London School of Hygiene & Tropical Medicine (LSHTM) and the University of Bern within the Multi-Country Multi-City (MCC) Collaborative Research Network. Using data from 732 locations in 43 countries around the world shows for the first time the actual contribution of human-made climate change in increasing mortality risks due to heat.

Overall, the estimates show that 37 per cent of all heat-related deaths in the recent summer periods were attributable to the warming of the planet due to anthropogenic activities. This percentage of heat-related deaths attributed to human-induced climate change was highest in Central and South America (up to 76 per cent in Ecuador or Colombia, for example) and South-East Asia (between 48 per cent to 61 per cent). Estimates also show the number of deaths from human-induced climate change that occurred in specific cities; 136 additional deaths per year in Santiago de Chile (44.3 per cent of total heat-related deaths in the city), 189 in Athens (26.1 per cent), 172 in Rome (32 per cent), 156 in Tokyo (35.6 per cent), 177 in Madrid (31.9 per cent), 146 in Bangkok (53.4 per cent), 82 in London (33.6 per cent), 141 in New York (44.2 per cent), and 137 in Ho Chi Minh City (48.5 per cent).

The authors say their findings are further evidence of the need to adopt strong mitigation policies to reduce future warming and to implement interventions to protect populations from the adverse consequences of heat exposure. Dr Ana M. Vicedo-Cabrera, from the University of Bern and first author of the study, said:

We expect the proportion of heat-related deaths to continue to grow if we don’t do something about climate change or adapt. So far, the average global temperature has only increased by about 1degC, which is a fraction of what we could face if emissions continue to grow unchecked.

Global warming is affecting our health in several ways, from direct impacts linked to wildfires and extreme weather, to changes in the spread of vector-borne diseases, among others. Perhaps most strikingly is the increase in mortality and morbidity associated with heat. Scenarios of future climate conditions predict a substantial rise in average temperatures, with extreme events such as heatwaves leading to future increases in the related health burden. However, no research has been conducted into what extent these impacts have already occurred in recent decades until now.

This new study focused on human-made global warming through a ‘detection & attribution’ study that identifies and attributes observed phenomena to changes in climate and weather. Specifically, the team examined past weather conditions simulated under scenarios with and without anthropogenic emissions. This enabled the researchers to separate the warming and related health impact linked with human activities from natural trends. Heat-related mortality was defined as the number of deaths attributed to heat, occurring at exposures higher than the optimum temperature for human health, which varies across locations. While on average over a third of heat-related deaths are due to human-induced climate change, the impact varies substantially across regions.

Climate-related heat casualties range from a few dozen to several hundred deaths each year per city, as shown above, depending on the local changes in climate in each area and the vulnerability of its population. Interestingly, populations living in low and middle-income countries, which were responsible for a minor part of anthropogenic emissions in the past, are those most affected.

In the UK, 35 per cent of heat-related deaths could be attributed to human-induced climate change, which corresponds to approximately 82 deaths in London, 16 deaths in Manchester, 20 in West Midlands or 4 in Bristol and Liverpool every summer season.

Professor Antonio Gasparrini from LSHTM, senior author of the study and coordinator of the MCC Network, said:

This is the largest detection & attribution study on current health risks of climate change. The message is clear: climate change will not just have devastating impacts in the future, but every continent is already experiencing the dire consequences of human activities on our planet. We must act now.

The authors acknowledge limitations of the study including being unable to include locations in all world regions- for example, large parts of Africa and South Asia- due to a lack of empirical data.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene
