New Study Reveals Climate Change as the Top Threat to Endangered Species: What You Need to Know

A recent article in BioScience highlights a pressing issue: climate change is now the biggest threat to species listed under the Endangered Species Act (ESA). For the first time, researchers have found that climate change surpasses other major causes of biodiversity loss.

Talia E. Niederman and her team from Defenders of Wildlife explored how climate change impacts endangered species. They analyzed data from ESA listings, assessments by the International Union for Conservation of Nature (IUCN), and new climate sensitivity studies. Their findings reveal that climate change now affects 91% of the 2,766 imperiled species in the U.S. and its territories.

In their research, they identified five main drivers of biodiversity loss: climate change, land and sea use changes, species overexploitation, pollution, and invasive species. A staggering 86% of U.S. species at risk face several threats at once. Notably, certain groups like corals, bivalves, and amphibians experience a higher number of dangers.

The researchers state, “With comprehensive climate sensitivity data, climate change is now as critical a factor as land and sea use changes. This may be true for a broader range of species, too.” They express concern that existing data may not fully capture the extent of climate change’s impact on these species. They urge the inclusion of climate sensitivity in ESA decisions and strategies to combat this growing threat.

Furthermore, they point out that there are knowledge gaps that could hide even more serious issues, especially for species needing updated assessments. As one researcher noted, “We don’t need more studies to see that biodiversity is under serious threat. Quick action on all five drivers of biodiversity loss is essential to prevent further extinctions.”

This research is urgent. With many species on the brink, it’s crucial to act swiftly and effectively to address these threats. As society grapples with the realities of climate change, understanding its impact on biodiversity will be key in shaping conservation efforts for the future.
