Climate action needed to avert 'health catastrophe'

To achieve sustained recovery from the COVID-19 pandemic and avoid an "impending health catastrophe," countries must commit to targeted action on climate change, health experts have urged ahead of the UN climate summit, COP26.

An open letter signed by more than 450 organizations representing 45 million called on national leaders and country delegations at COP26 in Glasgow next month to put "human health and equity" at the center of change mitigation and adaptation actions. The list of signatories represents more than two thirds of the global health workforce, according to the World Health Organization (WHO).

The WHO's COP26 Special Report on Climate Change and Health, The Health Argument for Climate Action, launched at the same time as the , outlined 10 recommendations for governments to "maximize the of tackling climate change," and "avoid the worst health impacts of the climate crisis."

Jeni Miller, chair of the environment section of the American Public Health Association, a signatory of the letter, told SciDev.Net: "The health community from around the world came together around this letter because we are profoundly concerned about the impacts [of climate change] we're seeing on people's health now, and that we know are going to get far worse if climate change is not fully addressed."

Outlining some of these impacts, the letter states that air pollution, especially from burning fossil fuels, is causing more than seven million premature deaths each year—the equivalent of 13 deaths every minute. It also highlights increases in food-borne, water-borne and vector-borne diseases, as well as the destruction caused by rising sea levels, and increasingly frequent floods, storms and heatwaves.

"Wherever we deliver care, in our hospitals, clinics and communities around the world, we are already responding to the health harms caused by climate change," the letter says.

According to Miller, no country is immune from climate change, but developing countries are feeling the greater impacts and have the fewest resources to respond.

Ayyoob Sharifi, an associate professor at Japan's Hiroshima University who specializes in urban climate change adaptation and mitigation, said: "Developing countries are expected to be disproportionately impacted [by climate change] due to their limited adaptive capacity as well as the rapid rates of urbanization."

Agnimita Giri Sarkar, a pediatrician at the Institute of Child Health, in Kolkata, India, and a member of the Indian Academy of Pediatrics, another signatory of the letter, told SciDev.Net that, in India and other developing countries, "heatwaves and air pollution coupled with increased urbanization are directly affecting the health of children and adults."

"To tackle climate change, a multidisciplinary team approach comprising of environmentologists, scientists, virologists, microbiologists, epidemiologists, and clinicians is necessary," she added.

The WHO's 10 recommendations include: committing to a healthy recovery from COVID-19; making health and social justice central to UN climate talks; prioritizing climate interventions that benefit health, society and the economy, and establishing climate resilient and environmentally sustainable health systems.

As part of the Paris Agreement adopted by governments in 2015 to tackle climate change, governments pledged to take action to limit global rise to 1.5 degree Celsius. However, Miller warned that national governments are not yet taking the level of action that is urgently needed to meet this goal and protect global health.

"We call on the leaders of every country and their representatives at COP26 to avert the impending health catastrophe by limiting global warming to 1.5°C, and to make and equity central to all climate change mitigation and adaptation actions," the letter urged.

Sharifi said the report and letter had come at "a very important time, as the negative impacts of on public health are becoming more and more evident."

"Given the resource limitations of many cities in developing countries, I recommend prioritizing investment in climate policies and measures that can provide co-benefits for and equity," he added.
