The largest study of its kind was led by the London School of Hygiene and
Their estimates showed that 37% of all heat deathsduring the summer periods were associated with the warming of the planet as a result of anthropogenic activities. The percentage of deaths caused by global warming was highest in Central and South America (up to 76%, for example, in Ecuador or Colombia) and Southeast Asia (48% to 61%).
Satellites underestimated global warming for decades
Their estimates also show the number of deaths fromanthropogenic climate change occurring in specific cities: 136 deaths per year in Santiago de Chile (44.3% of the total number of heat deaths in the city), 189 in Athens (26.1%), 172 in Rome (32% ), 156 in Tokyo (35.6%), 177 in Madrid (31.9%) and so on. The authors say their findings provide further evidence of the need for drastic action to reduce future warming.
“We expect that the proportion of heat-related deathswill continue to grow unless we take action or adapt to climate change. So far, the average global temperature has risen by only 1 ° C, which is a fraction of what we may be facing. Especially if emissions continue to rise uncontrollably, ”said researchers from the University of Bern.
Scientists added that global warming affectson health in several ways, from direct effects associated with wildfires and extreme weather conditions to changes in the spread of vector-borne diseases. However, they also added that the rise in mortality and morbidity is still too high. Given that future climate scenarios predict significant increases in average temperatures, extreme events such as heat waves will lead to even greater risks to human health.
