Yeah but I'm talking about the entire Earth as a whole
not just the temperature of some water in one place on the Earth
Seawater can actually go below zero C and not freeze. Just a couple degrees (if that, maybe only like -1)
it can! but the average is 16 degrees
and more ice melting than usual lowers that global average seawater temperature
which affects the whole water cycle!
Are you trying to tell me, that if you had a glass of water, with ice cubes in it, and you stuck a hairdryer pointed at it, to melt the ice cubes faster, the water would be colder than if you didn't use the hairdryer?
That sounds ass backwards based on what I know about thermodynamics. My expectation is that in both cases, the water will be the same temperature in either case, however one will have used way more ice to "maintain" that temperature.
Sometimes science is counter-intuitive however.
Is anyone willing to try this experiment?
the ocean cools because there is now millions and millions of gallons of colder water in it, flowing in the currents, when it was originally concentrated in glaciers, as ice.
Edit, and since antarctica sits on a landmass, it adds to the volume of the ocean as well. It isn't floating on water.

If we're assuming you are somehow only getting the blow dryer to give heat to the ice, the ice would melt faster than it would if it were just exposed to the water, and then it would turn into 0 C water, cooling the temperature of the water.
So you would theoretically see the temperature of the water drop faster than if you didn't heat the ice cubes.
But the temperature of the system is not just the temperature of the water. You have to factor in the temp of the ice, + the state change into water.
However, if you compared both systems, the one where you applied the blow dryer would eventually rise to a greater temperature than the system where you did not apply the blow dryer. Assuming these are isolated systems where ambient air temperature isn't taking over the whole process.
Now, I have probably succeeded in confusing anyone who bothered to read this because I sure as fuck confused myself
Sometimes I give serious thought to going vegetarian because of the huge environmental impact of the meat industry
but then I remember that meat is delicious
(man I could PROBABLY swing vegetarian if you had a gun to my head, but you are prying my cheese and eggs from my cold, dead hands. Vegans, I salute you but you are insane)

I'm doing an Ethics class where our prof basically did a class arguing that there is no real moral/ethical justification for eating meat. It was interesting, but ultimately ignorable due to one fact: Meat is fucking tasty.
Well, what amused me was his argument that the meat industry is terrible and that all cattle are raised in cramped conditions a la the meat farms in the U.S. Basically he was arguing that this made eating the meat unethical as it caused suffering to the animals and made their lives generally shitty, which I agree with when it comes to factory farming like that.
Problem is, most of the beef people eat up here is local and from personal experience, I can attest that his claims about cattle farms are complete bullshit when it comes to Alberta. But then again, I tend to not try to argue with university profs, especially ones like this guy who are a fan of smacking down dissenting opinions with scholarly articles and thinking that the lack of rebuttal proves him correct. To put this is context, this is a second year level course for undergraduates.
Isn't another major factor of the melting ice the fact that it is freshwater, and dumping a lot of freshwater into a saltwater system is bad
yes, in fact one of the predictions of this is a fucked up Jet Stream causing colder temperatures in Europe (which is, coincidentally, experiencing a massive cold snap at the moment)
there is also albedo, which is the tendency of stuff to reflect.
Ice reflects a lot of heat back into space. Less ice = less albedo = more heat = accelerated warming
also there is the factor of permafrost warming up and releasing more greenhouse gases. = accelerated warming

basically there is no stopping it
Also heating of the ocean reduces its ability to absorb CO2.
and dead zones...There's a link between increased water temperature and there prevalence right?
Interesting article, but as you said, not really applicable to the US. As I understand it most US cows are not pasture-fed, but instead raised on a steady diet of farmed grains. Seems like in AMURRICA it's more environmentally friendly to eat the plants instead of having it converted into cow
if I lived in Australia though, I'd be eating the hell out of some kangaroo meat

Kangaroo is fucking delicious. It's like a slightly tougher, heftier steak.

We always focus on greenhouse gas emissions as a huge factor in Global warming. And this completely makes sense.
But how much impact is all the heat civilization actually outputs having? Would it be significant or just a drop in the bucket?
Like all the oil we pump out of the ground - a lot of it gets converted to CO2 and then ends up in the air. But it is also all burned, releasing heat. Nuclear Power Stations release a shitload of heat into the environment. How much impact could this all be having?

So eat more meat to keep their populations down.
