There are several ways to potentially lower sea levels by 1 meter, but most of them involve large-scale engineering projects and would have significant environmental, economic and social impacts. Some of the ways are:
Building large dams: Building large dams across the mouths of major rivers could slow the flow of water into the ocean, potentially lowering sea levels.
However, this would also have a significant impact on the environment and the communities living near the dams.
Melting ice caps: Melting ice caps, such as the ones in Antarctica and Greenland, are a major contributor to rising sea levels.
One way to lower sea levels would be to reduce the amount of ice in these areas, but this would be a difficult and controversial task.
Building artificial islands: Building artificial islands or barriers around coastlines could protect against rising sea levels, but it would also be a very costly and complex undertaking.
Desalination: Desalination, the process of removing salt and other minerals from seawater, could also be used to lower sea levels. However, this process is currently expensive and energy-intensive.
Carbon capture and storage: Carbon capture and storage is a technology that captures carbon dioxide (CO2) from power plants and other industrial sources and stores it underground, preventing it from entering the atmosphere.
This could also help to slow down global warming and therefore the melting of ice caps, which can contribute to the sea-level rise.
It's important to note that these methods have significant drawbacks and are not simple solutions, and would require extensive research, development, and collaboration among governments, industry, and the public.
Additionally, the best approach to reducing sea level rise is to reduce greenhouse.
