I was working on a glossary for one of my books and thought you might be interested in this:

angels and guardians

There are angels and guardians of Earth that exist in the past,

present and future. They keep the ecology and energies of the

 earth in it’s lands and seas and mountains and continents all

 in balance over long periods of time. However, there will 

likely be a time here on earth where all continents are gone 

sometime between 500,000 and 800,000 years into the future.

 So, when Arcane’s people come to settle here on earth it is 

not recognizable except as a water planet because all continents

 have been knocked down under the seas. However, the 

volcanic vent that created the Hawaiian Islands still exists

 as the tectonic plates move and continues to create islands.

So, Arcane’s family eventually lives on the biggest of these 

in the vicinity of the Big Island of Hawaii now 1 million years

 into the future after all the continents are under water caused

 by high winds and global Climate changes and wars.

I wrote this above in my glossary for a book I'm working 

on now. 

I wanted to share more regarding the changes to the surface

 of the planet during the next 500,000 to 800,000 years. 

At some point when winds are 500 to 1000 miles and hour

 a lot everything nailed down moves around a lot during 

this time period caused by global Warming and wars over 

enough resources for humans to survive all this. Water becomes

 a problem and growing food becomes a problem and both 

then have to be done under ground because of the speed

 of the winds.

All these wars over resources help end continents as we 

know them. This then moves most people under water to 

protect themselves from the continents being mowed down

 by the things moving in the winds like (everything not nailed

 down from boulders to cars to houses to trees and everything

 else. Also, when you have winds that fast trees and plants are

 all gone from the surface then dust moving at 

1000 miles per hour would be fatal for human beings too 

because it would be like being sandblasted to death also.

 So, moving under the oceans in specific places would be

 a survival place for those who remain on earth and haven't 

colonized other worlds by then. However, you would have 

to move to places not being blown into oceans where you 

were too. So, there would be new technologies allowing 

humans to survive on earth than now under the oceans 

because the oceans continue always here on earth along 

with the Atmosphere no matter what temperature the waters 

and atmosphere become over time. However, the life forms

 on earth likely would change during this time. We are 

already seeing fish die offs and more jellyfish on the oceans 

now too. and the problem with this is that jellyfish often 

sting baby fish and this kills them also. So, as the waters 

warm you will have more jellyfish and less regular fish 

so the things that eat the fish are more likely to die including

 human beings that only have fish to eat to begin with. 

So, unless people move to other areas to grow food or to 

grow fish in special areas of waters around the world people 

will die a lot from not having fish to eat worldwide starting

 this year many places on earth.
