Global warming alters temperature ranges critical to plant and animal survival.
Species may migrate, but many face physical or ecological barriers.
Extreme weather events and habitat loss are already causing mass die-offs.
Climate change is accelerating faster than species can adapt.
Coral bleaching, mangrove die-offs, and fish migration are signs of stress.
Changes in rainfall, ocean acidity, and sea level further threaten biodiversity.
Some species may evolve or relocate, but many will not survive.
