CO2 Is The Number to Watch When the trend for atmospheric CO2 trend begins to falter and fall, we can expect global average temperature to follow. Atmospheric CO2 rise now exceeding IPCC 1.5°C scenarios Figure 5.The central estimate of the forecast annual CO 2 increment for 2024-2025 in the context of the frequency distribution of the observed annual increment for each year in the Mauna Loa record
