Did anyone watch the 60 minutes special last night? Lots of very well known and respected scientists are predicting the average temperature of the world could rise 3 or 4 degrees during the next 100 years. Glaciers are retreating all over the world which is the real sign of problems. I think that most agree that there is a gradual warming trend right now however no one seems to be able to agree on the cause. Is it just part of a natural cycle or it being caused by man's activities since the industrial revolution?
