1,500 deaths in recent European summer wave occurred due to climate change, study estimates
Human-causing climate change is responsible for killing about 1,500 people in the European Heat Wave of last week, A first type of fast study is estimated,
Those 1,500 people “have died only due to climate change, so they would not be for burning of our oil, coal and gas in the last century,” said Frederic Otto, a climate scientist at the Imperial College in London.
Scientists at Imperial and London School of Hygiene and Tropical Medicine used colleagues-reviewed techniques to calculate that about 2,300 people in 12 cities were probably likely to heat in high-temperature bouts last week, with about two-thirds of them dying of additional degrees.
A heat dome has created dangerous heat conditions for Europe’s large swaths, airing wildfire in Turkey and inspiring heat alert in many countries.
The previous rapid atribution studies have not gone beyond evaluating the role of climate change in meteorological effects such as additional heat, floods or droughts. This study goes a step further to connect the use of coal, oil and natural gas directly for those who die.
“Heat Waves are silent killers and measuring their health effects,” said Gary Consentinadis, a biostatistian co-writer at Imperial College, is very difficult to measure. ” “People do not understand the actual mortality of summer waves and this is because (doctors, hospitals and governments) do not report the heat as an underlying cause of death” and instead credits it for heart or lungs or other organ problems.
Of the 1,500 deaths responsible for climate change, the study found that more than 1,100 people were 75 or older people.
Climate change heats the heat wave
“It is in summer, so it is sometimes hot,” the study’s lead author Ben Clarke said at a Tuesday’s news conference at Imperial College. “The effects of climate change have pushed it to several degrees and whatever they do brings more groups of people in dangerous fields and that is important. That is what we really want to reveal here. For some people it is still hot, fine weather, but now a huge area of population is more dangerous.”
Extreme heat, such as being felt in most parts of the middle Canada, is more than just uncomfortable. This can also be dangerous because it tries to cool on the body due to stress.
Researchers saw in London from 23 June to 2 July; Paris; Frankfurt; Budapest, Hungary; Zagreb, Croatia; Ethens; Barcelona; Madrid; Lisbon; Rome; Milan and Sasari, Italy. They found that excessive heat from greenhouse gases added 2 to 4 C, except for Lisbon, which was a more natural heat wave. Otto said that London has around 4C. Climate change only added about a degree in the peak temperature of the lisbon, the study was calculated, mostly due to the modeling effect of the Atlantic Ocean, Otto said.
That additional climate-conversation-causing heat added the most additional deaths in Milan, Barcelona and Paris, and the least in Sasari, Frankfurt and Lisbon, found in the study. The 1,500 figure is the middle of the range of overall climate-related death estimates that goes from about 1,250 to about 1,700.
How do scientists weigh climate change, calculate deaths
Wednesday’s study has not yet been reviewed by a colleague. It is an expansion of the work done by an international team of scientists, which conduct rapid atribution studies to discover the fingers of global warming in the increasing number of extreme weather events worldwide, and combine with long -established epidemics research that examines death trends that are considered normal.
Researchers compared what the thermometer read the thermometer last week would say that the use of fossil fuels would have led to a world without planetary fuel in a world without greenhouse gases. Health researchers then compared the estimates – there are no concrete figures yet – what has happened to the deaths from heat will be expected to death for each city without an additional heat of heat.
When the temperature collides with a historical height, it can also affect each part of the body as well as mental feeling. But what does it think? Lauren Pelé of CBC visited a laboratory, where it is being studied to experience what happens when the body is heated.
There are long -established formulas that calculate and used additional deaths from normal depending on the location, demographics, temperature and other factors, which are said, Otto and Consentinadis said. And health researchers take into account many variables such as smoking and chronic diseases, so it is comparing the same people except temperature, so they know what is the defect, Constentinadis said.
In 2021, the study generally linked the deaths from additional heat to human-causing climate change and carbon emissions, but not specific events such as the last week’s hot spell. A The study in 2023 Nature Medicine has estimated that since 2015, the temperature in Europe for every degree Celsius rises, there are an additional 18,547 summer deaths.,
As Europe fights its latest wave of excessive heat, experts say it is in part because the Mediterranean Sea is no longer cooling in winter, increasing temperature on the ground.
Studies such as Wednesday are “finishing the game of estimating the loss of health due to continuous burning of fossil fuels,” Dr. Dr. Dr. Visconsin’s Director of Health, Energy and Environment Research Center at the University of Wisconsin. Jonathan Patz said. He was not part of the research, but said that “the most updated climate and health methods were combined and found that every fraction of the degree of warming cases about excessive heat waves.”A Canadian emergency room doctor and President of Global Climate and Health Alliance, Dr. Courtney Howard said, “This type of study helps us to see that reducing the use of fossil fuels is health care.”
