Climate change is radically transforming the planet’s ecosystems, putting thousands of species at risk worldwide. A recent global meta-analysis of extinctions due to climate change reinforces the urgency of taking drastic measures to protect global biodiversity before it is too late.
Increasing risks to biodiversity
Climate change is already causing global extinctions, and the latest models predict that this risk will accelerate significantly. According to an analysis involving more than five million projections, global warming could drive 30% of species to extinction under high-emissions scenarios. The most vulnerable ecosystems, such as coral reefs, tropical forests and polar regions, face challenges that threaten both iconic and lesser-known species.
Extinction debt: a critical caveat
The concept of extinction debt underscores that many species are in decline towards extinction, even if it has not yet become apparent. This phenomenon is of particular concern for those species with small ranges or that inhabit hyperdiverse regions, such as the tropics and oceans. In addition, the planet’s “hidden biodiversity,” which includes as yet undiscovered species, may be at greater risk than currently estimated, leaving a gap in ecosystems and the food chain.
Scientific advances and persistent challenges
Methods for predicting extinctions have improved since the last meta-analysis in 2015, incorporating more detailed biological data on individual species. These advances have made it possible to identify the most threatened species and develop more targeted conservation strategies. However, the overall picture remains alarming: current actions are not sufficient to prevent worst-case scenarios. While global policies place the world at an increase of 2.8°C, even this level of warming will pose a significant threat to a large percentage of species.
A crucial point for climate action
The results of the meta-analysis highlight a critical trade-off: act now to limit global warming to 1.5°C or face a future where biodiversity loss is inevitable. Technological advances have provided viable solutions to reduce emissions, but these must be implemented urgently and decisively. Protecting biodiversity requires a global commitment that includes effective conservation measures and a shift to a sustainable model.
All species at risk, from the most iconic to the least known, play a vital role in ecosystems. This is a call to action to protect our planet and ensure a future where biodiversity thrives.
