Warmer worlds have more water vapor in the atmosphere, and colder worlds have less. We cannot control this.

I thought I would address this because it is very very important because of the global warming we are presently dealing with.

As the ice melts (north and south and at altitude worldwide) the water turns blue away from white (with ice) the white with ice reflects the sun back into space whereas the Deep Blue or Blue Green of the oceans without ice absorbs the heat of the sun rather than reflecting it back into space.

The heat is not stored in land masses because heat dissipates off of land masses in the winter.

But, water holds the heat to great depths of at least 50 feet deep worldwide so this heat stays in the oceans. So, then when more sun comes down on already warm water it doesn't take much at all to create evaporation. This evaporation doubles or triples the amount of clouds and fog and other moisture in the air all over the world.

So, this causes humidity to increase even as the heat of the air increases too which is what is causing all the deaths like in Japan when you raise the temperature to 106 degrees (the hottest it has ever been there) with high humidity you get thousands in the hospital from heat and you have at least 40 dead in Japan and at least 10 dead in S Korea as well.

So, as the air temperatures rise the humidity and moisture content of the air increases which kills more and more people unexpectedly all over the year daily and yearly especially between the months of April and October in the Northern Hemisphere.

Warm air can hold more moisture than cold air can. This is what is going to likely kill the most people from the heat worldwide in humid areas over this century. just like we just saw in Japan and South Korea.
