Point being, there are million and millions of variables that can and does contribute to the rising sea levels. I think it's pretty naive to assume it's because the poles are melting... Can they contribute? Sure. How much does it actually contribute? aha... see the issue. You see the icebergs melt... would not affect sea levels. Ice on land will contribute. It's impossible to quantify this and stupid to say that is the reason the seas are rising. I'm sorry, even you have to see that.
:erm:

Rising sea level models are based on the melting of land based ice - Mostly the Glaciers and Ice-sheets of Antarctica and Greenland.

https://en.wikipedia.org/wiki/Greenland_ice_sheet

Area 1,710,000 km2 (660,000 sq mi)
Length 2,400 km (1,500 mi)
Width 1,100 km (680 mi)
Thickness 2,000–3,000 m (6,600–9,800 ft)

https://en.wikipedia.org/wiki/Antarctic_ice_sheet

Approximately 61 percent of all fresh water on the Earth is held in the Antarctic ice sheet, an amount equivalent to about 58 m of sea-level rise.[3] In East Antarctica, the ice sheet rests on a major land mass, while in West Antarctica the bed can extend to more than 2,500 m below sea level.

Proof? When certain notions are held with a religious fervor ... much like quoting Scripture, you can prove anything you want on the internet ... It cuts both ways. But cut it does. Sheep from goats.

Maybe point out what I posted to be incorrect? You seem to have a comprehension issue :eek:

The fact that you think that there are millions of reasons for sea level rise and that such a rise could not possibly be linked to land ice melting..

https://en.wikipedia.org/wiki/Sea_level_rise

There are two main mechanisms that contribute to observed sea level rise:[8] (1) thermal expansion: because of the increase in ocean heat content (ocean water expands as it warms);[9] and (2) the melting of major stores of land ice like ice sheets and glaciers.

So I'm gonna jump in here with a few direct questions:

How long before the industrial age was the level of carbon in the atmosphere stable?

How much has the average global temperature varied in that time period?

And is it true that the most recent "little ice age" is the coldest that it has been on this planet in the last 10 000 years, and is it not true that during the reneissance era that the planet was warm enough for people to farm crops in Greenland, which is now completely covered in ice?

The earth had more CO2 in its atmosphere naturally before and was way warmer thousands of years ago as well.

The climate is always changing gradually in one direction or the other.

However what climate change deniers fail to realise is the rate at which the temperature is increasing. It is a scientific fact that CO2 traps heat better than oxygen yet a dumbass will still tell me that we're not contributing to the increasing temperatures. :confused:

The earth was actually cooling down before the 1900's to make matters even worse. Not only did we contribute to climate change but rather reversed it in the opposite direction.

A child can read this data and understand its significance:

Are you disputing that there are millions of reasons why the sea level is rising? Or what not entirely sure what you getting at?

I think stick to arguing in N&CA section. You are going to get a very bloody nose in here. I never said melting land ice does not affect rising sea water. I actually confirmed it does. But to what extent given the magnitude of variables can't be calculated. I suggest you go read my post a couple of times, understand what I'm saying then post links. You don't even comprehend what I'm saying in that pretty straight forward post.

I'll accept rep once you realise what I actually typed :p

Yes.

There a three primary reasons.

Thermal Expansion
Melting Glaciers and Polar Ice Caps:
Ice Loss from Greenland and West Antarctica

:crylaugh: I'll take my chances thanks, you concern is noted though.

Why can't it be calculated? We know pretty accurately how much land ice there is in Greenland and Antarctica (linked in my first post). We know how much water there currently is in the oceans, why on Earth do you think that this is something beyond our ability to calculate?

I'll accept rep once you realise what I actually typed :p

Okay, so perhaps provide us with the the source of your more up-to-date information?
https://www.washingtonpost.com/news...y-2100-scientists-say/?utm_term=.a1c943f94f15

I'll match you fear mongering claims of a 58m rise in see levels with a more recent one of 2m in the next century.
oceans could rise by close to two meters in total (more than six feet) by the end of the century. The melting of ice on Antarctica alone could cause seas to rise more than 15 meters (49 feet) by 2500.

Still over the top I think, but it does enough to proof how ridiculous your claim is that all the ice on land might somehow melt to cause a 58m rise.

If you reality want to fear monger you should look into how a increase in freshwater could affect ocean currents and cause havoc with with our weather patterns.

I'll give you a few more tries, you still seem to not comprehend the post.

By last reports I think they said there is about 269,000 tons of plastic in the ocean.
https://phys.org/news/2014-12-scientists-total-weight-plastic-world.html

That in itself contributes to a rise.

That is just plastic.

Add to that, land and other substances and solids added to the ocean daily.

Rising models are built on taking rise in the ocean over a period of time. and then predicting what X amount of water would do to it also. In my post I said, Ice on land does contribute to rising sea levels. Yes, you can go read that again just to make sure. The problem is they can't quantify how much of the rise is contributed to the melting ice.

But wait, there is more:
https://www.nasa.gov/feature/goddar...s-of-antarctic-ice-sheet-greater-than-losses/

Mass Gains of Antarctic Ice Sheet Greater than Losses

:confused:

So you have water running into the ocean, yet there is snow falling on Antarctic which is greater than the losses suffered.

Not the point I wanted to make but anyway, interesting read since you mentioned Antarctic...

Seriously, go read what I posted, understand it and I'll engage you again. This is going to get tiresome very quickly...

The earth had more CO2 in its atmosphere naturally before and was way warmer thousands of years ago as well.

https://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's_atmosphere
Over the past 400,000 years, CO2 concentrations have shown several cycles of variation from about 180 parts per million during the deep glaciations of the Holocene and Pleistocene to 280 parts per million during the interglacial periods. Each part per million by volume represents approximately 2.13 gigatonnes of carbon in the atmosphere as a whole.[9] Currently it constitutes about 0.041% (equal to 410 ppm) by volume of the atmosphere[10][11], which corresponds to 3000 giga metric tons. The global mean CO2 concentration is currently rising at a rate of approximately 2 ppm/year and accelerating.[12][13]


https://en.wikipedia.org/wiki/Geologic_temperature_record
The gradual intensification of this ice age over the last 3 million years has been associated with declining concentrations of the greenhouse gas carbon dioxide, though it remains unclear if this change is sufficiently large to have caused the changes in temperatures. Decreased temperatures can cause a decrease in carbon dioxide as, by Henry's Law, carbon dioxide is more soluble in colder waters, which may account for 30ppmv of the 100ppmv decrease in carbon dioxide concentration during the last glacial maximum. [1]

It's not actually clear how much of a role CO2 has in changing the climate.

The climate is always changing gradually in one direction or the other.
No one said otherwise.

However what climate change deniers fail to realise is the rate at which the temperature is increasing. It is a scientific fact that CO2 traps heat better than oxygen yet a dumbass will still tell me that we're not contributing to the increasing temperatures. :confused:
The question is by how much.

The earth was actually cooling down before the 1900's to make matters even worse. Not only did we contribute to climate change but rather reversed it in the opposite direction.

Sorry, but this silly 1k year graph doesn't actually prove anything, and from what I can gather those cold periods you see there is the coldest the planet has been since the end of the last ice age 12 000 years ago. In fact they used to farm in Greenland back when it was warmer...
