What is a key consequence of climate change on biodiversity?

A key consequence of climate change on biodiversity is the reduction of species’ adaptability and an increase in extinction rates. As climate change causes shifts in temperature, precipitation patterns, and extreme weather events, many species are faced with challenges that limit their ability to survive in their current habitats.

species that cannot adapt quickly enough to the changing conditions, such as shifts in food availability or habitat loss due to rising sea levels and changing ecosystems, are at greater risk for extinction. Furthermore, the rapid pace of these environmental changes can outstrip the natural processes of evolution that may otherwise allow species to adapt over time. This mismatch between the rate of climate change and the adaptive capacity of species leads to a decline in biodiversity, as vulnerable species may not find suitable habitats or may face increased competition from more resilient species.

The other options do not accurately reflect the relationship between climate change and biodiversity. For instance, climate change does not lead to increased stability of ecosystems or the expansion of all species' habitats, and there are indeed observable effects on biodiversity due to changing climatic conditions.
