  • Description: The Paris Agreement aims to keep global warming well below 2°C above preindustrial levels with a preferred ambitious 1.5°C target. Developing countries, especially small island nations, pressed for the 1.5°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°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. Key Points We use a signal‐to‐noise metric to examine changes in local climate between 1.5 and 2°C global warming The wealthiest areas of the world suffer far less local climate change than the poorest places if the 1.5°C target is breached Failing to limit global warming to 1.5°C will likely hamper sustainable economic development in the poorest regions of the world
