If the current global warming, Aided by humans continues, lakes around the world will likely experience by 2100, a general warming. Even far above what experienced so far.
This is the conclusion of a new study by an international team of limnologists and climate modellers. They used temperature data from the lakes simulated by a climate computer model last generation.
This study to the Global warming effects In lakes on Earth, it covers the period between the years 1850 to 2100.
It is the first model of this type and captures the dynamics and thermodynamics of lake systems in a way integrated with the atmosphere.
Human-aided global warming
Instead of running the computer model To look into the future only once, the scientists used a set of 100 simulations from past to future. These were run on one of South Korea’s fastest computers (“Aleph” at the IBS-Institute for Basic Science).
Every test generates a slightly different realization of natural climate variability, while responding to the effects of anthropogenic warming.
Along the same lines, it occurs from the increase in greenhouse gas concentrations and contributes to global warming.
Using this ensemble modeling approach, scientists were able to separate the range of temperature variations in the lakes that occur naturally of those caused by human interference.
This allowed the team to estimate for the first time the point at which lake temperatures will permanently exceed natural limits. A situation known as conditions without analogues.
Although surface warming affects to the species of the surface layers of lakes, some organisms can migrate vertically to find thermal habitats more suitable.
It is therefore essential to also consider how it penetrates global warming in the underground layers.
