A new study to reassess the Earth's atmosphere's sensitivity to carbon dioxide stated that they hope that the average rise in Earth's temperature will not exceed 2.5 degrees Celsius by 2100 can be largely excluded if greenhouse gas emissions continue at the current rate.
The study, which was conducted within the framework of the Geneva-based Global Climate Research Program, provides the first clear progress in decades towards narrowing global warming caused by doubling levels of carbon dioxide since pre-industrial times.
The results of the study show that doubling the levels of carbon dioxide will lead to an increase in the average global temperature by between 2.6 and 4.1 ° C above pre-industrial levels, which makes the lowest rise more than one degree above the previously estimated range of scientists, which ranges from 1.5 And 4.5 ° C.
"With that in mind, we're on a pathway that will double our CO2 by our current emissions, by about 2080," said Zaki Hosfazer, a climate scientist at the Brack Throw Oakland Institute think tank in California and involved in the study."Climate change is as bad as we thought," he added.
According to Sky News, there is scientific consensus that the goal of limiting average global warming to 1.5 ° C, as reported in the Paris Climate Agreement in 2015, is almost certainly unattainable unless greenhouse gas emissions are reduced.
The study, which was published, Wednesday, in the Review of Ovigovics, was based on computer simulation using satellite observations, historical temperature records, and prehistoric temperatures from sources such as tree rings.
He said the study provides "a better sense of how accurate global warming is with increasing carbon dioxide in the atmosphere."
It also confirms that the world is on the way to severe sea-level rise and other severe climate impacts.
