Global warming happens when our planet's atmosphere gains energy, causing temperatures to rise. Scientists collected data from different sources about Earth's temperatures, natural disasters, chemical emissions, and population growth. They used this data to create models to understand and predict temperature changes. By analyzing the information, they saw that the temperature increase in March 2022 wasn't higher than in the previous 10 years. Comparing different models, the Holt model was the most accurate in predicting future temperature changes over time. Ultimately, they found a clear link between time and global temperature.
