Climate tipping points could be triggered by ‘committed warming’
Schematic figure illustrating (a) the main carbon sources and sinks, and with radiative forcing described in terms of an effective CO2e concentration, accounting additionally for non-CO2 greenhouse gases. (b) The conceptual differences between net zero and constant-concentration commitments. In net zero scenarios human emissions are reduced, allowing for the change in radiative forcing to be negative and stabilizing global mean temperature (GMT). In constant concentration scenarios, atmospheric radiative forcing is held…
