Emissions and Atmospheric CO2 Stabilization: Long-Term Limits and Paths

摘要: The objective of stabilization greenhouse gas concentrations is often envisioned as a monotonic approach to higher constant concentrations. For CO2 concentration over finite time, emissions must peak and then gradually zero 1,000+ years, regardless the level. While this intellectual architecture has proved useful, we suggest consideration broader range scenarios, including ones in which net decline period time resulting maximum followed by long-term lower Carbon cycle model results illustrate these scenarios.
