Climate change has impacts all over the planet; CO2HE becomes an even more harmful greenhouse gas due to warming. This finding suggests that many of the predictions made to date about the future effects of global warming may be underestimates because our emissions are much more harmful than previously believed.
This is the main conclusion of a study recently published in the journal ‘Science’ and conducted by scientists at the University of Miami, which shows how complex the atmospheric system is. “Our finding is that as different actors regulating the climate respond to increases in carbon dioxide, carbon dioxide itself is becoming an even more powerful greenhouse gas“says Brian Soden, professor of atmospheric sciences at the Rosenstiel School and lead author of the paper.
To reach this conclusion, researchers We used state-of-the-art climate models and other tools to analyze the impact of CO2 increases on the stratosphere, the upper atmosphere, where the buildup of carbon dioxide causes it to slowly cool.
This phenomenon is what feeds back the CO2 that ultimately remains confined to the lower atmosphere. this causes the molecules to retain more heat than beforethus, the greenhouse effect is further increased, if possible.
The study, conducted by the University of Miami, drew on a series of climate model simulations provided by the Coupled Model Intercomparison Projects (CMIP), a series of experiments that took into account data from dozens of the world’s most complete climate models. Assessments of the Intergovernmental Panel on Climate Change (IPCC).
A panorama different from what you think
Results contradict theories used so far In long-term climate forecasts. And until now it was thought that the amount of heat trapped in the atmosphere was proportional to the CO2 emitted (scientists knew this as radiative forcing). In other words, they viewed it as a constant that never changed over time. But, These results show that the relationship between the two is exponential, rather than linear.
The study concludes that the relationship between the amount of heat trapped and radiated is exponential rather than linear
“This result reaffirms us that carbon emissions must be stopped as soon as possible to avoid the more serious effects of climate change,” Soden said. Haozhe He also adds the following in his statement: “Future increases in carbon dioxide will have a stronger warming effect on climate than the equivalent increase in the past.”
The authors of this article believe that the data warrant evaluation of climate models. “These findings have important implications when it comes to interpreting both climate changes that have occurred in the past and climate changes that will occur in the not-too-distant future,” He concludes.
