biome shift and biodiversity loss

Detailed explanation-1: -The risk of species extinction increases with every degree of warming. In the ocean, rising temperatures increase the risk of irreversible loss of marine and coastal ecosystems. Live coral reefs, for instance, have nearly halved in the past 150 years, and further warming threatens to destroy almost all remaining reefs.
Detailed explanation-2: -Climate change has the potential to substantially alter the distribution of the planet’s terrestrial ecoregions and biomes. Our results suggest that by mid-century, 54% and 22% of global land area will experience climatic conditions that correspond to different ecoregions and biomes, respectively.
Detailed explanation-3: -Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
