Ok, so they prob have an adverse effect...there is still no definite proof, that is my point...yes the IPCC says its real, there are still scientists that say it isn't real. It's also nice to know that i don't understand anything about science and that I've been wrong about everything....I don't think I have...you guys don't seem to know the definition of theory (but thats another discussion) and take all theories as established fact, something they definitely ARE NOT.
oh contraire, things that are considered leading theories are the best explanation we currently have. They are virtually established fact e.g. the theory of special relativity (which we utilise for extremely accurate time keeping for GPS) and the theory of evolution.

I hate this "some scientist don't agree" bullshit. So what? The leading scientists in the field all agree, and the vast, vast majority in other fields agree too. There is never "definite proof." Please prove to me that F=ma, that is a law, not a theory, so you should be able to prove it.

I f'd your ma

pman is of a horrible breed of climate change skeptics. Let's move on.

Where should I invest in property given the estimated rises in sea levels?

e=mc^2

the other day
in the paper
or zoo
i cant remember

it said some asteroidhit earth with x kg of energy
and i was like
wat
kg of energy
but i guess, e=mc^2
or

If sea levels rose by 7m my house would have a view of lake cook (formerly known as cooks river)

If sea levels rise does that diminish the achievements made by those who have reached the summit of Mt Everest, the highest point of land on this planet?

Think about the mountaineers, guys.

In fairness I guess we should measure in terms of distance from the earth's core.

Re estimating the achievements of these heroic mountaineers in terms of distance from the core is going to be a serious feat. A feat worthy of the scientific prowess of pman.

Hello my name is Cat and I am a marine scientist

I am perfectly aware of this fact, the ting is, temperatures will have to rise quite substantially (something in the order of 15 degrees i believe) before you melt the antarctic land ice...
Incorrect

I think if you read my post I said that the sea ice would melt first....
But it won't melt first. It may melt faster, but the Greenland ice will melt at much the same rate as the sea ice that surrounds it. The fact is that there's a fucktonne more land ice than sea ice, and therefore will take a lot longer to melt (convection of heat as well rah rah).

I'm having a go at those south pacific nations that claim they are visibly sinking and quite clearly aren't.
Tell that to Tuvalu

In fact, the small portion of the northern hemisphere that is land ice will probably melt before the southern hemisphere.
Correct. In land area, sea ice > land ice in the northern hemisphere. But there's proportionally more land ice because there's ice sheets and they're rather thick. So.. yeah.

and to quote the the rational wiki link "a consensus itself proves nothing"

the acidification of the oceans is a load of junk, the limestone will just desolve thereby neutralizing the incoming acidity, as already mentioned in this thread....the bit about Greenland is true but exceedingly unlikely.
Wahey incorrect. At, ah, "equilibrium" CaCO3 (NOT "limestone" - think more coral skeletons, etc, which become limestone) also dissolves as a function of pressure/depth as well as a function of CO2 in water. Extra CO2 upsets this balance, and no, that does not "neutralise the incoming acidity" such that the effect is stabilised or reversed.

Disturbed rainfall patterns, well, the Sahara was an ocean or a rainforest or something like that from memory.
Point?

Depends on where. I did some stochastic modelling work on this two years ago. For the south coast of NSW, safe distance is approximately >50m from shore.

exists but doesnt really matter, the earth goes through changes of temperature every few hundred years, its a natural cycle
granted its being sped up like crazy cos of fossil fuels and human activity, but honestly- meh.

Add 'thousand' onto the end of 'hundred' and you'd be closer to a true representation.

Elizabethan dress (16th century)


21st century dress

pman grade proof that in 400 years it has gotten far warmer and therefore the global climate changes in "few hundred" year cycles

lol....there is no such thing as an established fact that is 100% true - only a well suppported and documented hypothesis that gives the best interpretation/idea of what is likely to happen.

theory of evolution can never be 100% fact (in a philosphical WHAT IS TRUTH?!?!?! sense) but the amount of evidence supporting it leads us to believe it's the best generalisation we have.

don't be so quick to blame us for your stupidity when all your points have been debunked.

damn it's like the fact there exists a few flat earthers means we should believe in a flat earth.

although i dont know, most proofs could be said to be theories as maybe we just havent encountered conditions where they are not true
something
