Climate change has become a major driver of species extinction, as habitat loss, rising sea levels, and extreme temperatures place enormous pressure on ecosystems worldwide. While many extinctions result from multiple causes, several species have already been officially declared extinct primarily due to climate change.

Species That Have Gone Extinct Due to Climate Change

Bramble Cay Melomys (Melomys rubicola)

This small rodent from Australia is considered the first mammal officially driven to extinction by human-caused climate change. Rising sea levels and severe storms destroyed its only habitat on Bramble Cay, a tiny island in the Great Barrier Reef, reducing vegetation by nearly 97%. Its extinction was officially confirmed in 2019.

Golden Toad (Incilius periglenes)

Native to Costa Rica, the Golden Toad is widely regarded as a victim of climate change. Changing weather patterns and prolonged droughts linked to rising temperatures destroyed its breeding grounds within the cloud forests, ultimately leading to its extinction.

Christmas Island Blue-Tailed Skink

This reptile species was declared extinct in the wild due to severe environmental changes, including those connected to climate instability and habitat disruption.

Hawaiian Birds

Several native Hawaiian bird species have gone extinct, including multiple species removed from the U.S. Endangered Species Act. Climate change has intensified the spread of diseases such as avian malaria by allowing mosquitoes to survive at higher elevations where birds once found protection.

Species Currently Threatened With Extinction

Polar Bears

Polar bears face growing threats as Arctic sea ice continues to melt due to global warming.

Sea Turtles

Species such as the Green Sea Turtle are at risk because rising sand temperatures affect the sex ratio of hatchlings during incubation.

Freshwater Dolphins

Freshwater dolphin populations are threatened by droughts, habitat destruction, and changes in river ecosystems linked to climate change.

Coral Reefs

More than 44% of coral reef ecosystems are under threat due to ocean warming and acidification.According to scientific studies, climate change is worsening conditions for more than 6,700 endangered species worldwide, while nearly 27% of animal and plant species are considered at risk because of its effects.If we truly want to protect wildlife and preserve biodiversity, stopping climate change becomes not only an environmental necessity — but also a moral responsibility toward the living world.
