In this episode you will learn how climate change will very likely change the length, frequency, and intensity of heat waves, which will increase over most land areas, with more warming resulting in more extremes. Dr. Hare will also discuss regional variations and impacts i.e. why the tropics is identified as the most high impact region and where warming of more than 4°C shifts the local climate to a fundamentally new regime. You will also learn about the social impacts of heat waves and how societies and ecosystems can be expected to be especially vulnerable and will face enormous adaptation challenges. For instance, agricultural yields will be impacted, and ecosystems in tropical and sub-tropical regions will be highly vulnerable.
