Although climate change poses a real threat for all the flora and fauna of the planet, there are species that are affected much more than others. One of the species that will suffer the most devastating effects of global warming will be all amphibians on the planet.
The greatest loss will occur throughout Spain, where many species will end up becoming extinct due to the high temperatures and the aridification process that various areas of the peninsula will suffer. Specific, the part of Eastern Andalusia will be the biggest loser, as it is an area that is particularly sensitive to temperature changes.
The amphibians that currently inhabit the Earth are species that have been able to survive the climate change that has occurred for hundreds of years. However, the severity and acceleration of current climate change is causing many amphibian species to rapidly disappear. Amphibians are one of the most threatened vertebrate groups globally, with nearly 41% of species classified as vulnerable, endangered, or critically endangered. For more information on threatened species, please refer to the article on some species that are most threatened by climate change.
Unfortunately, some of the effects of climate change Amphibian populations are already beginning to suffer from them. The high temperatures that have occurred in recent years have caused the larvae cannot complete their metamorphosis, causing a significant decline in the amphibian population. Furthermore, global warming is altering and contaminating the habitats in which amphibians thrive, negatively impacting their lives.
Climate change affects these animals' habitats, reducing water availability and increasing the frequency of critical events such as fires, droughts, and storms. Rising temperatures alter the life cycles and distribution of species, forcing many to move to higher altitudes where conditions are more favorable.

Amphibian species are particularly vulnerable to climate change due to several factors: their water dependence for reproduction, their skin permeability which makes them sensitive to dehydration and the fragility of their habitats. It is estimated that 39% of species are at significant risk of extinction Due to these factors, a percentage that could increase with the progression of climate change.
The impact of climate change is combined with other threats, being the habitat destruction and diseases, especially chytridiomycosis, two of the main causes of the decline in amphibian populations. The disease caused by the chytrid fungus, Batrachochytrium dendrobatidis, has decimated many populations worldwide, and is more prevalent under conditions of environmental stress, such as prolonged droughts or rising temperatures. This situation is related to the impact of climate change on ecosystems, as analyzed in the article on How climate change affects flora and bacteria, as well as reptiles.
Conservation efforts are essential to protect these threatened species. Initiatives are underway to restore and create suitable habitats for amphibians, which involves restoring ponds and wetlands that may have been degraded or eliminated. One example is the project in the Montes de Valsaín mountain range, where measures are being implemented to conserve and enhance populations of various amphibian species.
Below are some of the most relevant elements that should be considered when addressing the situation of amphibians in the context of climate change:
- Alteration of life cycles: Variations in temperature and water availability directly affect the reproductive and developmental cycles of amphibians.
- Increase in diseases: Environmental stress facilitates the spread of deadly diseases that affect amphibian populations.
- Habitat destruction: Human activities, such as agriculture and urbanization, are reducing amphibians' natural habitats.
- Need for conservation actions: Implementing projects that emphasize the restoration and protection of habitats that support amphibian populations is crucial.
Among the most effective actions being carried out are ecosystem restoration and the creation of ecological corridors that facilitate amphibian migration and adaptation to changes in their environment. However, for these actions to be effective, it is essential to continue researching and monitoring amphibian populations, as well as promoting public education about the importance of these species and the challenges they face.
Amphibian conservation is not only crucial for biodiversity, but also has important implications for the health of ecosystems as a whole. Amphibians play a vital role in the food chain, and their disappearance could trigger cascading effects affecting other species and the ecosystem services they provide. Therefore, it is essential to analyze the synchrony in ecosystems and how this influences the populations of different species.
The scientific community and conservationists must unite to intensify global efforts to protect amphibians. This includes developing effective policies that address not only climate change but also other threats that impact their survival.
The time to act is now, and although the outlook is alarming, there are opportunities to reverse the trend through concerted, science-based action. History shows us that by protecting biodiversity, we are also ensuring a more sustainable future for our planet.
