3CvTLh_0bCq3qGy00According to a recent study, the climate catastrophe would result in an estimated 83 million more deaths by 2100.

The study used a novel metric known as the “mortality cost of carbon” to calculate the number of deaths caused by emissions from adding one more metric ton of carbon dioxide (CO2) to the atmosphere.

The study’s measure is based on average temperatures of 4.1 degrees Celsius by 2100.

According to the study, increasing 4,434 metric tons of CO2 in 2020, which is comparable to the lifetime emissions of 3.5 typical Americans, “causes one more death globally in anticipation between 2020 and 2100.”

According to a peer-reviewed study published in the journal Nature Communications, Americans create considerably more carbon than people in other nations. For example, 25 Brazilians or 146 Nigerians release the same amount of carbon during their lifetime.

Furthermore, the report predicts that by mid-century, average temperatures will have risen by 2.1 degrees Celsius (3.8 degrees Fahrenheit) above pre-industrial levels, based on current emissions levels. According to the study’s publication, this is the widely agreed-upon threshold beyond which the worst effects of the climate catastrophe would worsen.

The estimates of fatalities are likely an undercount, according to Daniel Bressler, the study’s author and a Ph.D. student at Columbia University said that the model only accounted in heat-related mortality. Rising death rates from air pollution, floods, and fires are also connected to the climate problem.

Although the study focused on individual carbon emissions, Mr. Bessler believes that climate regulations affecting companies would have a bigger influence than what people can do.

He said, “My view is that people shouldn’t take their per-person mortality emissions too personally.”

“There are a significant number of lives that can be saved if you pursue climate policies that are more aggressive than the business as usual scenario.”
