Okay, to clear a few things up.
1. Roughly every 10,000 years our planet undergoes a disruption in it's thermaline cycles, which is underpinned by the equator's warming, and the icecaps cooling the water in the oceans, every now and then the temperatures spread out and even out a bit, making poles warmer, and allowing the wholeplanet to rise up in temp just before it crashes, after it crashes, the equator gets hot for a bit as the caps flashfreeze, this flashfreeze is the start of an iceage, which then creeps down, allowing the cold of space to dominate most of the planets temperatures, eventually pulling out even the equators heat.
2. Humans have produced a relativly small amount of CO2 and CO compared to even one volcanic erruption, and since some are going all the time, one could say that we have had little if any impact on the actual "green house gasses" which also include methane, which humanes really don't make that much of, but the earth does.
3. Even if we were to be the cause, the friggen enviromentalist of the last era, the anti-nuclear ones, are to blame for our current CO2 levels being as high as they are by forcing us to burn more coal that we would have otherwise, by the stats i've heard 70% of human CO2 production is from coal fired power plants ( mostly U.S. and now largely China, no regulations there) and 10% is from motor vehicles.
4. One major issue that people have to get over to understand this is that The world is not static merely because we are now here, it will continue to change and be dynamic as it has been in the past
Yes, they are melting, yes it is cyclical, and yes, there is nothing we can do about it.
One interesting correlation is the cycle of the caldera under Yellowstone national park and the timing of the ice ages, that's one giant volcano, and it is active once again, just as the ice age begins to loom over the horizon, hrm.... maybe i should move
