decide for yourself?

That guy is the stupidest, most arrogant little shit I have ever laid eyes on. He doesn't say 1 single thing about global warming lol. I would happily punch him in the throat and laugh while he choked to death. Hopefully he's a troll, but he still pisses me off a ridiculous amount. Trolling gets dumb kids like that killed. ><

Aha, found where he fucked up. Sea water is salt water, the frozen ice has fresh water, so when the ice melts the densities won't be the same, so the sea level will change. Suck it, bitch.

Oh, and global warming isn't just about the melting of the ice caps. It's about carbon dioxide absorbing radiation and converting it to heat, which it very fucking clearly does.

we've all heard the term "the tip of the iceberg"... 90% of the iceberg is under the water level, meaning that, once melted, that 10% that isn't is going to go under, raising the water level... not only this, but there is a LOT of ice that is NOT under the water level currently. Once greenland melts, the water level will go up just from that... This kid is a fucking idiot, he starts off by saying that global warming doesn't exist, then he goes on to explain, that there is indeed global warming (causing the ice to melt), and that through his eyes, this isn't a problem.

It's the natural fluctuation of the earth's temperature. It's going to start going back to normal soon enough, and when it does people will think an ice age is coming.

The kid isn't as dumb as you might think. If all the water/ice was fresh water, then floating ice would NOT raise the water level when it melts (it gets more dense, hence takes up less volume, and if you use archimedes' principle it works out to no change in the water level surprisingly enough). However, the kid's wrong because the ice has quite a bit of fresh water while the ocean is salt water, so and the density of saltwater ≠ the density of fresh water, so the water level will not stay the same when the ice melts.

And to ILTST4, it is a fact that carbon dioxide absorbs radiation that normally passes through the atmosphere, and due to the relative scarcity of CO2 in the atmosphere even a "small" change in the amount of CO2 will have a dramatic effect on the atmosphere's absorption of said radiation. When that radiation is absorbed, it's often re-emitted in all directions, so a shitload of it comes back down to earth and heats shit up.

Also, this motherfucker is a dumbass because: THERE IS A SHIT-TON OF ICE THAT IS NOT IN THE OCEAN ALREADY. And it is MELTING.
