Tuba says it's because global warming is decreasing the salinity.


So melting ice is responsible for freezing water?

changing the salinity changes the point at which water freezes. Changing the salinity also changes the density of water with the potential of disrupting global oceanic currents, changing how heat is distributed around the world. Warming can cause glaciers filled with fresh water to melt and dilute the salty oceans. Diluted oceans will have a higher freezing point, creating more salty oceanic ice.

I need a little better explanation because that does not explain why lakes and streams are fresh water.

Don't know if you are serious, but as per earlier posts, water evaporating from the ocean is fresh water.
That fresh water falls as rain on land, replenishing fresh water lakes, rivers and streams.

Regarding the question of historic ocean salinity, in general as sea levels fall as during global glaciation, salinity rises. As sea levels rise during interglacials, salinity generally declines. There are variances in salinity d/t factors other than fresh water mixing. E.g. temperature, current, density.

Or that his logic is at least as valid as climatologists since clearly they do not understand the myriad of variables that led to major earth climate changes over millions of years.

I am far more cynical than that.

I think they understand a great deal of those variables. But they also understand the variables of funding, if they were to publish on topics antithetical to the CO2 warmist meme.

Tigerinatl stated the ocean is salty because the rain washes salt into the ocean. I was looking for a more detailed explanation of his statement.

If his statement is true wouldn't rain also wash salt into lakes and streams?

To be honest I have never really questioned or even thought about why oceans contain salt or where the salt comes from.

He was being a smartass I presume. Was not serious.

Or even the Second Law of Thermodynamics...

No, that's the Second Rule of Thermodynamics.

The Second Law is something different.

The oceans were salty long before there was land. It came from hydrotherml vents and volcanism. Additional salts from land have added to the oceans over hundreds of millions of years, but the oceans' salt content have been stable for many hundreds of millions, if not billions of years. This is in spite of the rise and fall of the oceans, the growth or retraction of glaciers, the forming of and retraction of ice sheets across the continents and the runoff of rivers and streams. Why is this?

It's because the salts in the ocean have reached a balance with runoff. The salts form new minerals at the bottom of the oceans. As these form, and salt is removed, new salts are constantly being added by runoff, geothermal vents and volcanos.

Except for places like the Black Sea, which has more than its fair share of fresh water inundation, the oceans are remarkably uniform in mineral composition and have stayed that way through all the various cooling and warming periods in the last few hundreds of millions of years.

Why, suddenly, are we to be concerned that water runoff from melting glaciers, or additional ice forming in the Antarctic is going to cause sudden doom and despair? Are we really so full of ourselves and our power that we assume our last 100 years or so (and the next 100 years) has the power to make changes that nature itslf can't make over hundreds of millions of years?

I just don't buy it. Will weather and climates change? You betcha'. Can we do something about ozone depleting chemicals released into the air? Sure. Can we stop the oceans from rising or falling? Let's not kid ourselves. The problem is, there is money to be made and most of us are too stupid to figure out how we, too, can profit from it.

When I do, I'm going to be on here like white on rice (I know... Racist!) exhorting all of you to pay those carbon taxes, buy my energy-efficient new 'green' battery, and most of all, buy my book on how YOU can make a change by protesting against all those mean Republicans who will drown the islands, rid the planet of polar bears and shut off the ocean conveyers. I'll invite each of you to attend my seminars (at an affordable, yet nominal fee), where you can stay in the same hotel with me at a special rate (meaning... I get a cut of the take), and for an annual membership fee you can join my society. Just think of the smug satisfaction you'll have, knowing that you personally 'made a difference' (in my bank account). Of course, there are some of you for whom, just participating isn't enough. Don't worry! For major contributors, you can have a personal meeting with me on my yacht, er, I mean my 'aquatic studies research vessel'.

Until then, and in the meantime, frick all this nonsense.

Good post.

The ocean is the great buffer.
