The Copernicus Climate Change Service predicts that 2024 will surpass this record, reaching an average temperature of 1.66°C. This alarming increase is due to the confluence of climate change induced by greenhouse gas emissions, deforestation and the El Niño phenomenon, which has intensified temperatures in the ocean and atmosphere. The research began with a bibliographic documentary analysis of the dependence on fossil fuels in the most polluting countries. China, the United States, India, Russia, and Japan were found to be 90%, 90%, 100%, 95%, and 90%, respectively, dependent on coal, oil, and natural gas. Subsequently, the rate of deforestation over the past five years was examined, noting that 50 million hectares were deforested in South America, 30 million in Africa, 25 million in Asia and 5 million in North America. When analyzing the global mean temperature change variable, the Shapiro-Wilk test was applied to verify the normality of the data. It was evident that the distribution deviates from normality. Using a year-by-year linear regression forecasting model, the temperature is projected to continue to rise to 2.07°C by 2030. This research found that we have exceeded in the last 60 years, by more than five times the capacity of the atmosphere by 200,000 megatons to support CO2. The environmental consequences of this warming will be severe. Winters will have temperatures below zero, while summers will be extremely hot, with wind chills that could exceed 50 °C at the beginning of the year, coinciding with the El Niño phenomenon in tropical areas. These conditions will severely affect the health of approximately 350 million people, who will be left without access to safe drinking water, exposed to extreme heat or winter frosts, and rising sea levels. It is crucial to take urgent action to reduce greenhouse gas emissions, protect forests and mitigate the effects of climate change. Otherwise, we face a future with serious consequences for human health and the planet.
