The Inequality of Climate Change From 1.5 to 2°C of Global Warming

The Paris Agreement aims to keep global warming well below 2 degrees C above preindustrial levels with a preferred ambitious 1.5 degrees C target. Developing countries, especially small island nations, pressed for the 1.5 degrees C target to be adopted, but who will suffer the largest changes in climate if we miss this target? Here we show that exceeding the 1.5 degrees C global warming target would lead to the poorest experiencing the greatest local climate changes. Under these circumstances greater support for climate adaptation to prevent poverty growth would be required.
