Mitigating Rising Sea Levels

It occurred to me that if and when global warming starts causing the world’s oceans to start rising that governments could mitigate this problem. Why couldn’t mankind attempt to control which land is flooded first and delay the flooding of more important areas, such as coastal cities?

First, letting gravity move large quantities of water would be the most cost effective solution. All streams and rivers could be partially or completely redirected to flow their waters into reservoirs instead of into the oceans. Of course, there would need a gigantic number of massive reservoirs throughout world to accomplish this, yet it is feasible. This will entail the intentional flooding of an incalculable number of valleys, plains, basins, caves, abandoned wells, canyons, homes, towns, property, etc. Furthermore, fish and boats would find it difficult or impossible to enter or exit rivers from the world’s oceans. Unfortunately, the environmental impact of diverting rivers would undoubtedly be colossal, but the greater environmental impact of the world’s oceans rising uncontrollably would be far worse. Most people in the world live in cities that are along the coastlines, and if these cities start to become unlivable by flooding, then chaos would quickly spread. Since civilization could not handle a significant percentage of the world’s population becoming homeless and jobless, civilization would be at serious risk of collapsing. The world’s economies would definitely collapse, epidemics would spread, food shortages would be common, and some governments would undoubtedly fall in disarray.

Second, if redirecting rivers is not sufficient, then more drastic methods would be necessary to control the world’s sea levels. Using maps to locate suitable regions, mankind could create canals or pipes from the oceans to regions of land that are both lower than the sea level, have low population densities, and not utilized much. Thus, controlling the flooding of certain less important regions will save other regions from being flooded.

Finally, since these solutions are only to mitigate the problem of rising sea levels, a more long term solution is necessary. Since coastal cities would be first impacted by the global rising of sea levels, all coastal cities would have to be planned to be evacuated and moved to higher locations. The logistics of moving the enter population of a city and its’ infrastructure, support, jobs, and homes has never been attempt before, let alone attempted for hundreds of cities at the same time. Unfortunately, it is impossible to move some types of important land, such as farmland and mines. So this solution may help; but with fewer of the world’s resources available, humanity will have a tougher road ahead.

I am well aware that the environmental and economic consequences of each of these suggestions are far beyond any person’s comprehension, but the dangers caused by global warming to civilization are well worth having a plan just in case rising sea levels are going to be a reality. Furthermore, these suggestions might not work, might not be sufficient enough, and may not be acted upon quickly enough, so at least please prepare yourself for rising sea levels.
