In the lead up to COP21 meeting in Paris, the Climate Action Tracker (CAT) gave an assessment of the likely effectiveness of Intended Nationally Determined Contributions (INDC’s) for mitigating greenhouse pollution and limiting Anthropogenic Global Warming (AGW).
According to CAT, all G20 members have presented their INDC’s to the UNFCCC for a proposed Paris Agreement at COP21. It appears that none of the G20 nations have commitments to hold warming below 2°C, or 1.5°C. Taken together, the CAT analysis shows that a very large emissions gap between INDCs and 2°C still remains.
A full briefing is available on their website.
About the CAT Figure: The thermometer shows the global-mean temperature increase above pre-industrial by 2100, with an uncertainty range originating from carbon-cycle and climate modelling (refer the CAT website).
