Dual approach needed to save sinking cities and bleaching corals

October 8, 2019 0 Comments Climate, Energy Policy, Environmental Awareness, Environmental Policies, Global Warming, Ocean Policy, Physics, Resource Shortage, Sports Science

Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them time in their fight against sea-level rise, ocean acidification and warming temperatures, a study by scientists suggests. In all but extreme situations, these interventions significantly buffer the impacts of climate change and can buy sinking cities and bleaching corals time to adapt until the beneficial impacts of global emissions reductions kick in.
