• 2018 | IPCC Special Report: Global Warming of 1,5°C


    The report was produced at the request of the "Parties", the countries that signed the Framework Convention on Climate (UNFCC).

    This report explains the consequences of a 1.5°C global warming and the short and long-term goals that are necessary in order not to exceed the 1.5°C warming.

    At the current rate of emissions, average global warming is likely to reach 1.5°C between 2030 and 2052.

    To limit warming to 1.5°C with ''no or limited overshoot'', global net emissions would need to fall by about 45% from 2010 levels by 2030 and reach ''net zero'' by 2050.

    Given the national emissions targets (NDCs) agreed in the Paris Agreement (2015), global warming is expected to exceed 1.5°C even if followed up with very ambitious mitigation measures after 2030.

    good to know

    Limiting global warming to 1.5°C instead of 2°C would mitigate the impact on ecosystems, human health and well-being.

    A 2°C rise in temperature would exacerbate extreme weather events, raise sea levels and reduce Arctic sea ice, cause coral bleaching and ecosystem loss, among other impacts.


    IPCC's special report starts with a quote from Antoine de Saint Exupéry (Citadelle, 1948): "Pour ce qui est de l’avenir, il ne s’agit pas de le prévoir, mais de le rendre possible." This means:

    "As for the future, it is not a question of predicting it, but of making it possible."
