Why have many experts decided that the aral sea might be beyond saving?

The Aral Sea is beyond saving because the surface is so dry and if water comes into the sea, it will evaporate quicker thanks to the hotter conditions. In a whole twelve years, it has only increased by 10%. It will also take a tremendous amount of resources and it would be very costly to try to restore the Aral Sea. It would take a lot of willpower and time to restore it as well. Also, the Aral Sea isn't affected by climate change or rising sea levels for anybody who thinks it is. It is a sea that is separate from the ocean.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
