Early onset of industrial-era warming across the oceans and continents

Journal Article


Abstract


  • The evolution of industrial-era warming across the continents and oceans provides a context for future climate change

    and is important for determining climate sensitivity and the processes that control regional warming. Here we use postad

    1500 palaeoclimate records to show that sustained industrial-era warming of the tropical oceans first developed during

    the mid-nineteenth century and was nearly synchronous with Northern Hemisphere continental warming. The early

    onset of sustained, significant warming in palaeoclimate records and model simulations suggests that greenhouse forcing

    of industrial-era warming commenced as early as the mid-nineteenth century and included an enhanced equatorial

    ocean response mechanism. The development of Southern Hemisphere warming is delayed in reconstructions, but this

    apparent delay is not reproduced in climate simulations. Our findings imply that instrumental records are too short

    to comprehensively assess anthropogenic climate change and that, in some regions, about 180 years of industrial-era

    warming has already caused surface temperatures to emerge above pre-industrial values, even when taking natural

    variability into account.
