The climatic crisis, which gradually covers the Earth, is becoming more apparent. A new research has shown that by 2100 lakes around the world may undergo an unprecedented increase in temperature, which will affect their ecosystems and biodiversity. This discovery, published on Scitechdaily, confirms that climate warming threatens not only surface but also deep layers of water systems.
According to a study conducted by an international team of scientists, world lakes may encounter a sharp and prolonged increase in water temperature. Using advanced climatic models and lake temperature data, the researchers were able to model both thermodynamic and dynamic changes in lake systems. The results were alarming: warming will be much more intense than ever observed.
Tropical lakes, in particular, will be particularly vulnerable to this warming. The study has shown that climate changes in the tropics occur faster than in other regions. This increase in water temperature will create serious problems for biodiversity of these ecosystems. Many aquatic organisms may not be able to adapt to new conditions and can be forced to migrate in search of cooler waters. However, in many cases, such movement may be impossible or too complicated, which can lead to loss of species.
In their work, the team of scientists used climate models that model the interaction between the atmospheric conditions and the dynamics of lakes. This allowed them to evaluate how anthropogenic warming can affect water systems. The study used data on the temperature of the lakes, as well as 100 simulations of the past and future, which were launched on one of South Korean's fastest supercomputers. These simulations have helped to portray potential scenarios for events by the end of the century.
Lake warming can have serious environmental consequences. Loss of biodiversity, changing ecosystems and reducing water quality can affect local communities that depend on these water resources. Water is a vital resource for many countries, and its changes can affect agriculture, fishing and water.
