1 Billion People Could Face Deadly Levels Of Heat Stress With Global Warming At 2 Degree Celsius: Report

While at 2 degree Celsius rise, one billion people would be affected, a 4 degree Celsius rise would result in nearly half of the world’s population living in areas affected by climate change, according to a new study

London: One billion people across the world could be affected by extreme heat stress – a potentially fatal combination of heat and humidity – if the global temperature reaches the 2 degrees Celsius threshold, a new scientific report released on Tuesday (November 9) by the UK Meteorological Office warned. “At the new temperature – according to new figures and a map from the Met Office – the number of people living in areas affected by extreme heat stress rises from 68 million today to around one billion,” the study said, adding that the 4.0 degrees Celsius rise could see nearly half of the world’s population living in areas potentially affected.

The experts, who based their findings on data from an international team led by the University of Exeter, said that tropical countries like Brazil and Ethiopia will be the worst affected.

This new combined analysis shows the urgency of limiting global warming to well below 2.0 degrees Celsius. The higher the level of warming, the more severe and widespread the risks to people’s lives, but it is still possible to avoid these higher risks if we act now, project leader and climate scientist Richard Betts of the Meteorological Office and the University of Exeter was quoted as saying.

Human heat stress risk depends on both temperature and humidity, and is indicated using the wet bulb temperature, which was limited at 32 degrees by the scientists conducting the research.

At this level, vulnerable members of the population, and those with physical, outdoor jobs are at greater risk of adverse health effects, they warned.

The report from the UK Meteorological Office comes as the UN Conference on Climate Change (COP26) running in Glasgow, Scotland, from October 31 till November 12 is expected to reach meaningful commitments to cut greenhouse emissions, achieve carbon neutrality and limit global warming to 1.5 degrees.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ populationindigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. 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 will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity,  that is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that 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 the country can become a Swasth or healthy India.
