Humankind, by a particular set of social systems driving the exploitation of nature, has been taking ravaging actions causing enough biogeophysical damage to the planet so that a new geological era has been discussed. Among all environmental threats, climate change has the potential to alter the planet in ecological and evolutionary ways through different aspects, such as ocean warming and acidification. Besides these global aspects, local stressors such as overfishing and pollution contribute to a greater threat to the world’s biodiversity. The Patagonian coast is a unique environment in the South Atlantic with populations of macroalgae forming underwater forests. Unfortunately, Patagonia is experiencing, besides climatic changes, the impacts of local stressors. In this chapter we demonstrate how global aspects interact with invasive species and changes in the continental runoff that locally or regionally threat important ecosystems in the Argentinean coast. The current and the future distribution of kelp species – the native Macrocystis pyrifera and the invasive Undaria pinnatifida – are predicted under different emission scenarios. Considering the available information, current trends, and future scenarios, we advocate in this chapter for further efforts to improve coastal management and resilience of Patagonia marine forests.
