the articles I browsed on this subject were fill with the twistings and turnings of those who want to say the the polar icecap is still shrinking, and who are unwilling to consider that things can change rather quickly.
I agree with you, I was simply using the poster I quoted's information to show why it doesn't necessarily mean increased warming.
Just because the ice is continuing to melt, doesn't mean that the warming is increasing, it just means it has warmed to a point to allow the melting. Go to your kitchen and do this. Get some ice cubes, and set them out in your presumably temperature-controlled house. They will melt. Does that mean your house is continuing to increase in temperature?
Let's try this experiment in a closed ecosystem. Put your ice cube in a plastic baggie, and then put it on the counter. Behold, it melts! Now take it and put it back in the freezer. Behold, it re-freezes! Pretty great.
But let's say one time you put it back in your fridge, and it doesn't re-freeze all the way. Even if you leave it overnight, it just gets slushy. This has nothing to do with the temperature at which water becomes liquid, and everything to do with the temperature inside your freezer, which is no longer getting cold enough to re-freeze all the water.
If you don't figure out what's going on in your freezer, eventually everything's going to thaw, and you lose your ice, your Eggo waffles, that venison you got last year...that would be kind of a bummer, wouldn't it?
So are you going to stand there and pretend your freezer isn't busted, or are you going to take measures to get it fixed before you lose everything?
There's a huge difference between thinking the climate is changing because of nature, and moronically thinking humans have the capability to drastically change it.
That said, I'm all for protecting the environment, but don't support many of the idiotic policies coming from some dumbass politicians/voters.

Prepare, of course... have the audacity to believe that humans can change the course of weather cycles, absurd. I posted the history of climate alarmists of the past 120 years. Scientists have a long history of this nonsense.
One of the honchos in the Clean Rivers Project was on Stossel and stated that "your Scientists are paid to say MMGW is a myth, while our scientists are not paid" Think about how backassward that statement is. "Their scientists" laugh all the way to the bank with their public funded grants.
Oh, and Antarctic ice has been increasing more than Arctic ice has been decreasing.
Ooops... a FOX link is automatically discounted and ignored. They'll say that sea ice isn't actually ice but caused by glacial ice falling off. So more sea ice is a sign of global warming. It's the same as this last Winter (the coldest in 50 years) is caused by... global warming.
Again, their argument is a two headed coin. If it gets too cold it's global warming, and if it gets really hot it's global warming.
Has anyone concluded that progressives blame mankind for EVERYTHING? They want us to live in caves, as they post from their I-phones and I-pads, from their hybrid cars. Hypocrites all.

Do you understand how much thermal energy is absorbed by melting ice? You are correct that the temperature has reached the point the ice can melt. What you fail to realize is that that melting ice is absorbing massive amounts of thermal energy and once it melts, the temperature rise will likely continue.
It takes 4.18 J of energy to raise one gram of water 1 degree Celsius but it takes 334 J of energy to melt 1 gram of ice. How much thermal energy is being absorbed by the melting ice caps?
To put this another way, melting ice cools the surroundings but that doesn't mean the surroundings are not being heated. Let's get back to the ice on your counter but let's make it a huge block of ice. Let's turn on your furnace and put a huge block of ice in the room to melt. The temperature of the room will not go up because of the melting ice until the ice melts and then it will go up. Because the melting ice absorbs large amounts of energy it masks the heating going on. There is a difference between heating and temperature rise. The temperature of Ice does not change during the melting process. It stays at 0 Celsius. If you look at a heating curve for ice, you'll see the temperature rises to the melting point then holds at the melting point until all of the ice has melted then starts to rise again. Right now the additional heat is going into melting the ice caps. We'll see what happens when they have melted.
