Oil on the surface of water would retard its evaporation.

Consistent with how I was reading things, pleasantly — barring some cautious hedging I'd made, based on the possibility that salinity could reflect mass changes, either when fresh water was added to the ocean via glacial melt or impoundment decreases (ocean mass increase) or via increased evaporation rates (ocean mass decrease).

On the other hand, the subtropical waters can be expected to become saltier in the future, for the same reason (increased hydrological cycle gives more evaporation in the subtropics, thus increased salinities in subtropical waters).

However, with me at least, a bit part of the deal is the increased acidity reducing fish harvests, water shortages, droughts severely reducing crops (sure — more rain, but more over the ocean, less on land — and with greater evaporation before the water trickles to a dry stream bed), increased heat reducing rice production and other heat sensative crops, the heat waves, etc..

... At sea surface temperatures above 80 Fahrenheit (27 C), evaporation loads the atmosphere with a critical amount of water vapor... a controlling factor seems to keep the same thing from happening on Earth.

For example, even though the volcanic effect is short - lived it will still have an impact on the water cycle - less evaporation because it's cooler therefore less water vapour, lowering temperature a bit more.

This number is based on the commonly presented estimate that 0.25 % of the mass of the atmosphere is water vapor, heat of evaporation of water, and specific heat of air at constant pressure.

Evaporation will commence long before this temperature is reached and were it not for the water vapour condensing on the inside of the container you would have clouds.

P.s. Myrrh is correct on some things 100 %, on others he is wrong, for example: «water evaporation cools the land and the sea, BUT, that doesn't cool the planet — only takes heat high up to be easier cooled by the shuttling oxygen & nitrogen, plus: as sun umbrellas clouds intercept lots of heat, high up — nevertheless, that heat is still in the earth's system — only O&N are» COOLING THE PLANET» Petra, do you believe that; O&N exist in the atmosphere?

The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

Slopes by angle can expose more or less volume of water to evaporation or flooding depending on degree of the slope to the height of water being displaced.

That causes an error of about 3 % in the calculation of heat transfer by evaporation from tropical seas — probably where most of water on this planet evaporates.

Again for example, during multidecadal periods when El Niño events dominate, the tropical North Atlantic trade winds would be on average weaker than «normal», there would be less evaporation, less cool subsurface waters would be drawn to the surface, and tropical North Atlantic sea surface temperatures would rise.

Can not increase evaporation in the sea, but extra water available on land; especially in dry countries as Australia = better climate.

LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was releasing more heat / was accumulating - > radiating + spreading more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation of dry heat and evaporating extra water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting more ice on arctic also as chain reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the evaporation deficit.

And even though on average more warmth will mean more evaporation, and therefore more water vapour in the atmosphere and more precipitation in some of those zones that already have ample rainfall, the pattern could be different in the arid lands.

On a water planet, most heat transferred from the surface is removed via evaporation, the heated air rising via convection.

Where do you think the energy that lifts water from the ocean through evaporation and deposits it up on land where it descends in rivers through power dams generating electricity comes from?

that is because the water vapor pressure is supralinearly related to temperature: that is, a temp rise from 289K to 290K has a larger effect on vapor pressure (so, most likely, on the evaporation rate) than does a temp rise from 288K to 289K.

As the temperature increases, the water vapor pressure (hence by inference the water evaporation rate on non-dry surface) increases supralinearly; that is, a 1K increase from 288 K is much less than a 1K increase from 308K.
