Of course the ice cap is melting, as it has for the last 20k - 30k years while we come out of the last ice age. As it has done every 100k years for at least the last 2 million years and probably much longer. This is not hypothesis, but based on solid evidence from many sources, grounded on the incontrovertible calculations of celestial mechanics which show how solar heating varies regularly as the orbit of Earth ibecomes more or less elliptical.

In contrast, there is not one scrap of evidence that obvious global warming is caused by equally obvious increase in the tiny 0.04% of CO2 in our atmosphere. On the contrary, the only firm evidence shows that warmer oceans release CO2 to the atmosphere, so the increase is a result, not a cause of global warming.

The carbon hoax is based on feeding this false causal linkage into computer models that are themselves based on shaky assumptions and incomplete data on how climate works.

Garbage in, garbage out.

Ever wonder why Greenland is so named?

Global Waring is a con. The climate always shifts back and fore from hot to cold mode

Recent studies of Anarctic Ice show that volcanism has risen more than 300% in the last 2000 years, with the rate of incresase on an almost logrithmic rise. What do volcanoes spew out in great abundance? CO2. Now isn't that interesting. Further, no one has explained the medival warming period when the vikings settled Greenland. They then left, as it turned colder, making the farms they had established untenable. Further, ice once reached as far south as Kansas before retreating. The coup de gras though is the fact, verified by NASA that Mars, Pluto and the moons of Jupiter are also warming. How many SUV's are there on those distant worlds?

Cause and effect. That is the key. If Greenland is melting, I have to take your word for it, that is the effect. However, proving the cause is harder. Are we still coming out of the last ice age as we have always believed? Is the sun activity near a peak? If Greenland is in fact warming, does that mean anything interms of a overall average? The Greenhouse Effect Theory, that man causes this is pretty easy to disprove, and very difficult to prove. First you must prove carbon dioxode levels in the air are increasing significantly and substantially. We do not even know what the original theory calls for. Surely a few parts per million is not it. Then you must prove the increase is caused by man's 5% contribution. Then prove the average temperature of planet earth is increasing, good luck, I could not do it. Two of three measurements say no, one says yes but they got caught cheating with unscientific measurements. Then prove Warming will cause flooding, only signs show dropping.

Wow! Maybe now, Greenland will look like it did when the Vikings named it.

But, of course, the ice probably had something to do with Viking flatuance....
