Is this caused by humans or not. No doubt part of it is, but it would seem some of it is not. If we go back 30,000 years we were in the middle of an ice age, and ice glaciers extended all the way to Maryland and Virginia USA. By about 10,000 years ago most of that had receded, and North America was beginning to look like it does today. Clearly that ice glacier that was more than one mile thick over most of Canada and it melted and had nothing to do with humans and industry. Arctic melt today is certainly part continuation of this long term very slow melt. Glaciers started to recede thousands of years ago and that continues. Again not to say human interference is not playing some role in the change of our climate, but climate was changing on earth long before we were around, and will continue long after human life has ceased to exist

There is absolutely no doubt that the current rise in overall world temperatures is almost entirely due to human activity. For one thing, it has happened far too quickly to be a largely natural phenomenon.
This question has been asked many times and examined by thousands of people in many countries who have devoted their careers to discovering exactly what is going on - by which I mean climate scientists who are completely independent of commercial or political interests. The overwhelming consensus of these people is that man-made factors are the predominant cause. The opposite point of view is proposed by people whose backgrounds show - more often than not - that they are far from independent but in the pockets of vested interests.
