The study looked at how human CO2 emissions impact global temperatures. By analyzing data on CO2 emissions and global temperature changes, the researchers found that as CO2 levels rise beyond a certain point (around 20,000 Mt CO2), global temperatures increase. They used regression functions to predict time-related patterns in CO2 emissions and temperatures, showing a direct relationship between higher CO2 emissions and rising global temperatures. In simpler terms, when we produce too much CO2, the Earth gets hotter. This highlights the importance of keeping CO2 emissions in check and balancing the natural carbon cycle to maintain a stable global climate.
