Earth's environment includes the atmosphere, the hydrosphere, the lithosphere, and the biosphere.
Climate change significantly impacts species adapted to specific temperature and rainfall patterns by altering their established geographic ranges and disrupting seasonal biological events. Because many species have evolved to thrive within a specific "climate envelope," rapid shifts in these conditions can exceed their natural adaptive capacity, leading to increased extinction risks.12
Key impacts include:
- Range Shifts: Many species are migrating toward cooler habitats, such as higher latitudes or elevations, to remain within their preferred climatic conditions. Species with limited mobility or those restricted to isolated habitats—such as mountaintop dwellers—face a high risk of extinction because they have no suitable areas to which they can relocate.1
- Phenological Mismatches: Warming temperatures cause shifts in the timing of life-cycle events, such as breeding, migration, and flowering. This can create ecological mismatches; for example, migratory birds may arrive at breeding grounds too late to exploit the peak availability of the insect larvae they rely on to feed their young.12
- Habitat Loss: Changes in precipitation and temperature can destroy specialized environments, such as cloud forests or coral reefs, leaving specialist species with nowhere to survive.2
- Increased Stress: Climate change often acts in concert with human-driven stressors like habitat fragmentation, making it harder for species to move or adapt.12
