Of current anthropogenic CO2 emissions, about 30% is absorbed by the oceans, in response to the higher CO2 concentration of the atmosphere. The net absorption by the oceans will stop when the equilibrium is restored at the ocean’s surface. This will only occur gradually after the atmospheric concentration ceases to rise.

Current national emissions targets can't limit global warming to 2°C, calculate Joeri Rogelj, Malte Meinshausen and colleagues — they might even lock the world into exceeding 3°C warming.

This study describes the coupling of the dynamic global vegetation model (DGVM), Lund–Potsdam–Jena Model for managed land (LPJmL), with the general circulation model (GCM), Simplified Parameterizations primitivE Equation DYnamics model (SPEEDY), to study the feedbacks between land-use change and natural vegetation dynamics and climate during the 20th century.

This report analyses the potential for changing track after 2020, from an insufficient global reductionby 2020, to two emission pathways that imply a reasonable chance to stay below 2°C and 1.5°C respectively.
