Climate Change is here and man made

[Damocles]

No I'm not at all. I'm suggesting that the amount of sea ice that is being created is the problem. That's why I said:

"Sea ice is the thing that people are arsed about as like an ice cube in a glass it contributes more to sea level changes"

How's about you just assume from now on that I actually know what I'm talking about so we can stop any further miscommunications and start looking at science?

I was just going to quote that right back at you. Sea ice is a tiny insignificant problem. It doesn't contribute more to sea level change. It contributes far far far far less. 4cm vs 70m of sea level rise using the link SWP's Back provided.

No, actually, I'm not going to assume that at all. I've taken a huge swerve away from that assumption and am now wondering whether you have a fucking clue.

Funny, I've had the same thought. Especially with you mixing up one of the simplest principles involved with ice melting which you've failed to acknowledge. And you completely missing the idea of the overall land ice mass reducing which you've failed to acknowledge. And your idea that having more sea ice is a "tiny insignificant problem" seemingly without understanding what exactly the effects of more sea ice has on the area nor exactly where this sea ice comes from in the first place. I think it's probably time for you to give up on this one if you're not going to acknowledge your own mistakes.

What i am understanding is that he is not talking about the sea ice melting, he is talking about the introduction of more sea ice. That is ice of land collapses into the sea.

Could be wrong.

No, it is you who've completely mixed up the principles. Sea ice barely contributes to sea level changes. You can demonstrate this by melting ice cubes in a glass. The effect of salt, is very minimal. The problem of sea level rises comes from water in the form of ice, which was previously land-based, being dumped into the oceans. This is why the Eastern Antarctic and Greenland ice sheets are supremely relevant because this is where the sea level rises will come from. The Eastern Antarctic is the land-based bit i.e. the important bit when it comes to sea level rises, and, the land-based bit is gaining mass. 60m of sea level change cannot happen without this big block of land-based ice melting. It is absolutely impossible. This whole thing would have to melt in pretty much its entirety. That only is not currently happening, but the opposite is happening, and even if things turned, and it started melting at a far faster rate than Greenland, it would still take several thousand years because there's so much of it.

Bit of both actually. I was trying to make the point that more sea ice contributes a greater spread of polynyas around which changes numerous markers on how the climate reacts and how ice forms around the area

No disrespect to either Damocles or Skashion here but this page alone is evidence enough as to why, fellow "imbeciles" like myself don't believe half the crap so called educated people and scientists come out with as they cant even agree with each other.

Earth has a history of hot and cold climatic periods and it will continue to do so regardless and like all other species that have ever lived or are yet to live, we will all end up going the same way.

Take the above to the bank!

He's not, he messed up by mentioning the ice cubes in the glass. When you melt ice cubes in floating water, the level stays the same.

No it doesn't!

Figure 1: A freshwater ice cube floats in a beaker of concentrated saltwater. Note that the ice cube floats much higher in the saltwater than it would in a glass of freshwater because saltwater has a greater density.

Figure 2: When the freshwater ice melts, it raises the water level. Freshwater is not as dense as saltwater; so the floating ice cube displaced less volume than it contributed once it melted.

We already know this. It is however, an insignificant problem. This effect is not causing sea level rise. Fresh water, from land ice sheets, is the big problem. The one people are arsed about.

But you just said:

How is that the same?!

In a paper titled "The Melting of Floating Ice will Raise the Ocean Level" submitted to Geophysical Journal International, Noerdlinger demonstrates that melt water from sea ice and floating ice shelves could add 2.6% more water to the ocean than the water displaced by the ice, or the equivalent of approximately 4 centimeters (1.57 inches) of sea-level rise.

Isn't this exactly what SWP said?
