Middle of the night thoughts...

If water expands when frozen ( a la caps being frozen off milk bottles on t'doorstep when t'war was on etc)......

...WHY, if the polar ice caps are melting, are sea levels increasing and not doing the opposite - and decreasing?

Just a thought.

I'd be grateful if someone could stamp on this little maggot in my brain please.

Thanks.

Because the water that was held in the form of ice turns liquid and flows into the ocean. Think of it in terms of when your freezer breaks down and deposits water on your kitchen floor times a few squillion.

...but the global volume is less?

The ice is in the ocean already?

Just doing the experiment 

large gin& tonic filled glass with ice first right to the top ice above the rim 

I shall see if it overflows when the ice melts 

to make this a proper experiment I shall use 3 or 4 different kinds of gin and sises of glass 

This could take a while 😗😉😂

Living 200 feet above sea level I could have a waterfront property if it all melts

Anything floating displaces it's own weight in water (simple law of physics)

Ice floats so it has a SG less than 1.

Therefore any floating ice will make tidily squat difference to sea levels.

However the ice above a land mass will make a difference. ie land based glaciers, antarctic land mass, etc.

however warmer air mass will hold more water vapour.

IMHO many scientists and "specialists" are over egging the effect on sea levels to help pursue their own agenda (and keep them in a job) or is that just the cynic in me.

I knew we could rely on you to do the research properly!:good:

i was going to post a simple paralell to explain the phisics of it all......it involved a hapeless mouse that slipped into an unflushed toilet bowl....and the mouse related the story to his family ending with the statement "if it wasnt for the log i would have drowned"

but in the order of good taste i wont take this anology an further..........

Thank you. I can sleep tonight now.

.....anyway my first g&t has melted and now there’s less in the glass 🤔

Did you, perchance, drink any whilst waiting Sir?

I thought this was going to be a waking in the night thought’s.

Like “Is she still breathing”. 🤔

 

I know that she is still breathing - it's the snoring that wakes me up!

As far as Eyefor's question goes - isn't it the ice on the Greenland land mass, which if melted, would significantly raise sea levels?

Put your finger in her mouth, works a treat, be quick though as bite reflexes kick in 😂
