"" The only place where there has been "significant" melting in the Northern Hemisphere is Greenland from what I've read. I've also read that the Polar Bear population is stable and even increasing.""
Hmm, aint heard this before. Polar Bears are moving habitat because of melting ice - each year they need to travel further and further away to find food. Also, if we are talking about an area half the size of the planet i.e. - "the northern hemisphere", we need to start talking about the "global" problem, an example would be glaciers that are disappearing all over the place. Analysis was performed by National Geographic ( they don't lie ) regarding this.

To qoute - they have observed an "alarming acceleration in the melting of Glaciers".
Some of the ice had been frozen for 50000 years. Now people can bring up a few hundreed years ago their was a warm century etc etc. As I have said before this is not denied, tempreture goes up and down. But - this particular warming trend is melting ice from tens of thousands of years ago. This time it is different.

"" The South Pole is getting colder, not warmer. The majar areas of temperature increase over the last few decades have been in CITIES which have grown substantially. Duh! More people = more energy use = more heat! Cities which have experienced little or no growth have experienced no increase in temperatures. I've seen the official government charts for dozens of US cities. They don't lie. ""
It depends what info you read on this. Parts of antartcica have certainly shown a cooling down trend - but it certainly is not all of the South pole. Entire sections have broken off due to ice thinning and then cracking. Hmm, an offical US government document trying to rubbish Global Warming, who would have thought!!!!!!

"" Many of the temperature monitoring devices are in places where the environment has changed. Some of them were in fields thirty or forty years ago and because of urban development they are in the middle of commercial real estate developments and surrounded by asphalt, skewing the readings. ""
Oh please show me the scientific evidence for this!!!!! I am sure some will be affected by this but to suggest that it is a major contributing factor to weather monitors giving a warmer reading smacks of desperation.
