Special Report: Global Warming of 1.5 ºC
Ch 03

Impacts of 1.5°C of Global Warming on Natural and Human systems

Why is it necessary and even vital to maintain the global temperature increase below 1.5°C versus higher levels? Adaptation will be less difficult. Our world will suffer fewer negative impacts on intensity and frequency of extreme events, on resources, ecosystems, biodiversity, food security, cities, tourism and carbon removal.
