New research from the University of Bristol has identified the countries that are at the highest risk of heatwaves. The study, which was published in the journal Nature Communications, analyzed data from 1979 to 2017 and found that countries in the Middle East and North Africa are most at risk.
The research team used a new metric called the Heatwave Magnitude Index Daily (HWMID) to measure the intensity and duration of heatwaves. They found that the HWMID has increased by 0.33°C per decade since 1979, which means that heatwaves are becoming more frequent and more severe.
The study identified 27 countries that are at high risk of heatwaves, including Qatar, United Arab Emirates, Saudi Arabia, Oman, Kuwait, Bahrain, Iran, and Iraq. These countries are already experiencing extreme heat, with temperatures regularly exceeding 40°C during the summer months.
The research also found that some countries in Europe, such as Spain, Portugal, and Italy, are also at high risk of heatwaves. These countries have experienced deadly heatwaves in recent years, with thousands of people dying from heat-related illnesses.
The study’s lead author, Dr. Dann Mitchell, said that the findings highlight the urgent need for action to address the impacts of climate change. “Heatwaves are one of the deadliest natural hazards facing humanity, and they are becoming more frequent and severe due to climate change,” he said.
The research team called for governments to take action to reduce greenhouse gas emissions and to implement measures to protect vulnerable populations from the impacts of heatwaves. They also recommended that countries invest in infrastructure to help people cope with extreme heat, such as air conditioning systems and shaded public spaces.
The study’s findings are particularly relevant as the world continues to grapple with the COVID-19 pandemic. Heatwaves can exacerbate health problems and increase the risk of respiratory illnesses, which could make it more difficult to control the spread of the virus.
Overall, the research from the University of Bristol highlights the urgent need for action to address the impacts of climate change and protect vulnerable populations from the deadly effects of heatwaves. As temperatures continue to rise, it is essential that governments and communities work together to implement effective solutions to this growing threat.
