More than a third of heat deaths are related to climate change, study says



More than a third of heat deaths in many parts of the world may be the result of increased global warming related to climate change. According to a new study that makes the case for taking active action to reduce greenhouse gas emissions to protect public health.

The new research, published Monday in the journal Nature Climate Change, was conducted by 70 researchers using data from key projects. In the field of epidemiology and climate models across 43 countries, summer heat-related deaths were driven by climate change averaged 37 percent during the 20 percent increase to 76 percent.

Some previous studies have performed similar analyzes for each city during a particular heat wave. But the new paper has applied these ideas to hundreds of locations and over the past several decades to draw broader conclusions.

Kristie L. Ebi, a professor in the University of Washington’s Center for Global Health and Environment, said: “It’s a thoughtful, insightful, and intelligent way to try to understand how climate change is changing heat-related mortality,” the study was involved in.

The world was already one degree Celsius warmer in the pre-industrial times. And it is predicted that global warming will increase with disastrous results. If global greenhouse gas emissions such as carbon dioxide and methane cannot be controlled,

“When brought together “Our findings show that the proportion of total and heat-related deaths during our study period can be attributed to human-caused climate change,” the authors. write

in many study areas scientists found “This cause-and-effect mortality rate already exists in the order of tens to hundreds of deaths each year” from the heat caused by climate change. The authors found that climate change increased overall mortality from all causes by up to 5 percent in some parts of the world. They detected increased mortality from climate-induced heat on all inhabited continents.

while the differences in mortality rates in different locations The study was complex and caused by various factors. This includes access to health services, architecture, urban density. and lifestyle Research highlights a divide between rich and poor regions. The researchers found that North America and East Asia were less likely to die from weather conditions. Some countries in Central and South America see more than 70 percent of heat deaths due to global warming.

The new paper comes amid recent research. This is about heat stress and economic inequality. both in the United States and around the world.

As more and more people around the world rely on air conditioners. This could lower the mortality rate while contributing to the release of heat on the planet. Climate change is also affecting the electricity grid. Failures have increased by 60% since 2015 in the US alone, meaning air conditioning crutches may become less reliable over time.

Ana Maria Vicedo-Cabrera Lead author of the new report and researcher at the Institute of Social and Preventive Medicine at the University of Bern in Switzerland. It said the study showed that climate change is not just a problem for the future. “We are thinking about climate change as something that the next generation will face,” she said. We are throwing stones at ourselves.”

The future looks even more frightening. she added “This burden will expand,” she said. “Actually, we need to do something.”

Dr. Abi agrees. “Climate change is already affecting our health,” she said, noting that “All heat-related deaths are preventable,” much depends on the decision, she said; Communities must adapt to the heat through measures such as refrigeration centers and heat action plans to help the most vulnerable, she added: “In the long term, there are many options that will affect our future vulnerabilities. including reducing our greenhouse gas emissions.”

Because scientists are unable to collect reliable data in certain parts of the world. including parts of Africa and South Asia, Dr. Vicedo-Cabrera. It is therefore reluctant to say that the average mortality the researchers found can be applied worldwide. “The estimates we have received do not apply to areas we have not assessed.”

Those gaps need to be filled. “Countries where we don’t have the necessary health information are often among the poorest and most vulnerable to climate change. and in related matters It is the main anticipated hot spot for future population growth,” the review said. “Getting these data will be key for science to provide the information needed to help these countries adapt.”

Dann Mitchell, Reviewer Climate scientist at the University of Bristol said in an interview that The increasing burden of climate change is causing heatwaves in a society like India. Where many people are already living in conditions of overcrowding and poverty, and where health services are already stressful, this could create “unsustainable things”.

“It will break at some point,” he said.
