A recent paper in the journal Nature highlights the disparity in how different regions of the world experienced climate change before the industrial revolution. Researchers created a model based on climate proxy data and found that major warm and cool periods were asynchronous across space. The Little Ice Age, for example, was at its coldest during the fifteenth century in the central and eastern Pacific Ocean, the seventeenth century in Europe and southeastern North America, and during the mid-19thcentury for much of the rest of the world.
