This episode describes how changes in ecosystems due to climate change impacts could result in loss of agricultural productivity and affect the ecosystem goods and services available to humans, such as water availability and food supply. Dr. Bierbaum illustrates how these impacts vary per region and how impacts on terrestrial ecosystems can differ under a 4°C world compared to a 1.5-2°C world. The episode will also explore how climate change has the potential to catalyze rapid shifts in ecosystems such as sudden forest lost or regional loss of agricultural productivity resulting from desertification. Ultimately, this episode will make you better understand how changes in ecosystems due to climate change impacts could adversely affect ecosystem services fundamental for human survival.
