Researchers at Dartmouth College say that between 1 and 2021, the extreme heat caused by the emission of six fossil fuel companies cost about $ 20 trillion.
Their study, which was published on Wednesday “Nature”, presents a peer-parallel method to emit certain climate damage. Their goal is to help the organization to keep the organization responsible for the expenditure of extreme weather that is responsible for holding the tobacco industry responsible for lung cancer Pharmaceutical companies OPWED is responsible for the crisis.
The research agency Zero Carbon Analytics has calculated 68 cases filed worldwide about the loss of climate change, of which more than half of them are in the United States.
“We have argued that the scientific case for climate responsibility is closed,” the author of this research writes Christopher Calhan, who received a PhD from Dartmouth College and Justin Mankin, a professor of geography Dartmouth Division.
5 top emitting agencies
According to the survey, about one -third of the total expenditure was attributed to the company, which could be tied up to more than $ 9 trillion dollars in climate.
These are the top-fishering companies and the dollar amount of researchers assume that they are responsible:
- Saudi Armco: $ 2.05 Trillion
- Gazprom: $ 2 trillion
- Chevron: $ 1.98 trillion
- AREMOBIL: $ 1.91 Trillion
- BP: $ 1.45 trillion
Researchers realized that 1% of the atmosphere had been thrown into the atmosphere of greenhouse gas since the beginning of the year, which did not include other extreme weather, such as hurricanes, droughts and floods. Emit data is taken from the public carbon major database, they say.
They used 1000 different computer simulations to translate this emission to the global average surface temperature of the earth without the emission of that organization.
Using this method, they determined that pollution from Chevron, for example, raised the earth’s temperature by .045 degrees Fahrenheit.
Researchers also counted how much contribution to the five hottest days of the year using 5 more computer simulations of each company, and then applied a formula that connects the intensity of extreme heat to the economic output change.
This system has been modeled on established techniques that scientists have been using for more than a decade to blame the incidence of extreme weather for more than a decade, such as the 2021 Pacific to blame the Pacific North -West -West wave for climate change.
Mankin said that in the past, there was an argument, “Who would say that it was my CO2 molecule that contributed to any other than this damage?” He said that the research was “truly made clear how the admirable denial of the disapproval no scientifically existed.
Armco, Gazprom, Chevron, Axon Mobil and BP did not respond to the requests for comments.
“The methods they use are quite powerful,” Imperial College London climate scientist Frederaike Auto, who is a world weather attitude, scientists who try to quickly Attribution Studies so that certain extreme weather events are worse by climate change and how much it is. He did not participate in the study.
Auto said, “If this outlook is more accepted by different groups, it will be better in my view. He still has not been successful in a climate responsibility against any large carbon imitar, but it has been shown that” scientific evidence can change how powerful “may change.
The study is a good practice and proof of concepts, but there are many other climate variables that Kalahan and Mankin, the number of damage to the companies probably did, Michael Mann, a climate scientist at the University of Pennsylvania, who was not involved in this study was not involved in this study.
