On a related note
Regardless of the cause, climate change is happening. It always does, but the current trend is that the poles are warming up rapidly and ice is melting, thus raising sea levels. What this means for the Mekong Delta of Viet Nam is quite worrying. Most of the land is only a few feet about sea level. Already there are many fluctuations depending on what season it is, wet or dry.
The delta is the most productive land in the country, so if that base is lost in the next hundred years, it could spell disaster, or if not that at least much pain. This is also ignoring the fact that millions of people call the delta their home, though the severity of such problems depends on its swiftness.
