Hi everyone Well first of all I must point out that I am not a scientist in any way, but I do have a couple of science-related things I would like to ask purely for a novel I am writing... I hope you will bear with me and I very much appreciate any responses!
At the moment it seems clear that due to global warming the Earth's ice caps are melting and this will eventually cause coastlines to be eroded. Some cities may even disappear underwater. But what I want to ask is: Is there any scientifically plausible scenario (however far-fetched this may be) which would cause all of the Earth to be completely flooded or in imminent danger of being so? One thing that did occur to me was that perhaps some of the pollutants being released into the atmosphere could combine in an unexpected way and affect rainfall, causing its water density to increase drastically... So a single rainstorm would release much more "concentrated" drops of water, causing severe flooding, adding to the problem of rising tides, and leading eventually to flooding of over three quarters of current land mass. I know this is far-fetched, but is there any way, scientifically speaking, that this could be possible? I am aware of the scenario put forward by Stephen Baxter in his novel "Flood", in which he suggests the Earth becomes flooded as a result of seismic shifts which then release vast underwater reservoirs. But I need something different, or I'd just be copying his idea... Does anyone feel my rainfall density idea "holds water" (apologies for the pun)? The other thing I would like to ask is regarding which area of science would be trying to solve such a flooding problem. Imagine two young, inexperienced scientists desperately trying to make a name for themselves by making a lot of the water "disappear". I'm not talking about some sort of civil engineering project, more an experimental method which involves delving into unknown areas of science and trying to alter water at a molecular level. In their recklessness they actually end up vapourising (or otherwise making disappear) far too much of the ocean water, leaving the Earth with dry seabeds. Which area of science would such individuals be likely to belong to? Would they be physicists? Chemists? Hydrologists? Could anyone point me in the right direction here as (I'm sure you can tell) I'm not a scientist myself. Many thanks for all your ideas!
