You know global warming doesnt mean that the globe just gets hotter? It essentially creates two severe sides. Its either intensely cold, or intensely hot.

This is a big deal and I don't think many people realize this. It aint no joke.

Um, "global warming" claims that CO2 traps heat into the Earth, a la Venus, creating a hotter planet all the way around. The model they are claiming is Venus.

The model you are claiming is Mars. Two completely different things. For what you say to happen requires either a reduced atmosphere (which is WAY bigger a problem than temperature, honestly) or a reduced capacity to deliver energy from the Sun. The third option would be for Electric Universe fans, where a change in atmospheric composition reduces the ability of the Earth to transfer Solar energy into heat...but that is a digression.

What you claim is wrong and illogical.

It would be interesting to see how this map lines up with the previous ice age. In the NE of the US, the snow line looks very similar to how far the glaciers progressed, at least that's what I remember from a Geology class a little while back.

Yes, that's why the Daily Fail ran the story - but the fact is, snow cover is similar throughout winter neary every single year. And sometimes more extensive. A comparison with January 2010 would be interesting and show how unremarkable this image really is.

It is interesting though that in an ice age, ice sheets do not extend much beyond the area of normal winter snow cover in an interglacial.

Nice graphic, good find. It's interesting to see the overall decline of northern ice and in NA the snow cover seems to move slightly more eastward and penetrate more deeply into the south over time. Less water locked up in ice, more water to spread over land as snow fall. The Jet Stream has been disrupted over NA and has allowed the colder, more dense, arctic air to reach further south and so in simplistic terms at least, things seem to jive.
