No Ice Thanks

Once upon a time forests ranged from coast to coast. When a fire started it likely never stopped until all of the carbon was released into the atmosphere. The trees grew back and absorbed the carbon. We've burned the trees and paved paradise and put up parking lots.

If you fill a glass with ice, and water, to the rim, the water level wont rise when the ice melts, it's called displacement. Test this theory when next ordering a drink at KFC.

Water expands as it freezes into ice. It then reduces in size as it thaws.So there is no chance your glass will overflow. You can test (prove) this by filling a glass screw to bottle with water and place in freezer overnight.

Displacement is the process of measuring volume. Displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place. The volume of the fluid displaced can then be measured, and from this the volume of the immersed object can be deduced (the volume of the immersed object will be exactly equal to the volume of the displaced fluid). You test/prove this theory by filling the glass with water ... then adding the ice. The volume of water on the bench will be equal to the volume of ice that was added.

It has been suggested that a large meteorite hit(s) .. and the resulting large dust cloud(s) caused one (or more) ice age ...

One other noted possible cause could also have been volcanic and/or geothermal activity ... causing similar dust clouds ...

Those parking lots all have grass verges, mowed byt he council too depending on where you live lol...
Talking grass though, that's one 'carbon sink' the experts refuse to use in their computer models and we all know why.
I love looking at old encyclopedias where it shows the full carbon cycle of plants reabsorbing carbon...

Always meant to do a fishtank youtube demo vid of that. Crunched the numbers one night after some serious googling and taking into account everything;
Volume of oceans
Amount of frozen ice/glaciers etc
I love when they show the icebergs and harp on about how huge they are. But they don't mention that the 2/3rds under water is already displacing ocean level and will displace 10% less once its melted

Now even to get the dramatic end of world 1m sea level rise or whatever it was, you have to have all the ice melt and stay melted.
This brings in a great property from high school physics class of the Latent heat of evaporation, the amount of energy required to do this and its huge.
This heat would also cause a lot more evaporation, I'm sure those that have enjoyed aucklands humidity know how much water the atmosphere can hold too.
We would all be completely roasted long before the sea level rose a significant amount. No GW or CC but KFC, Kentucky Fried Calamity!

fluctuations in the suns heat output, fluctuations in the orbit of the earth, volcanic eruptions both causing heating and pushing dust into the atmosphere causing cooling. being hit by space debris once again causing dust in the upper atmosphere all of these have triggered ice ages at various times. Also once you start the process of cooling going it feeds on it's self as the ice building up reflects heat back into space causing more ice to build up.

You had to go and write something that makes sense, and could even be correct, didn't you

Geez!!!

Wonder how many blades of grass are required to hold as much carbon as a tree?

He's right you know.

Before the white people there was no ice for the black people to put in their coke from KFC.

[Tazz]

s they have since the end of the ice age...

We're actually still in an ice age.

There was a good speech given by an Un Zedder to the house of commons (I think, or the tea drinkers Parliament, something governmental) on this topic that is worth a Google for. Sorry I don't have the link handy.

Would it be more accurate to say the volume of water on the bench will be equal to the volume of water used to make the ice? Given that the ice expanded slightly during freezing lowering it's density?

Also they fail to account for erosion.

Some of the finest humour I have read on here in this thread.

Actually ... it would be more accurate to say the volume of water on the bench is equal to the volume of ice below the waters surface. as the ice would not melt that fast.

As for the density ... which would you prefer to jump onto from a helicopter ... onto ice ... or the water ... ???
