Yes, it is happening, but not for the reasons the gov't is telling us. If you do some serious study and research you will find the earth has undergone major climate change about 8 times in the past 300K years it is estimated. One if those times is what killed off the dinosaurs. Studies estimate it takes a good thousand years to go thru a cycle. While burning fossil fuels may not be helping the situation, it isn't the cause...if it were then why has this happened 7 or more times in the past long before fossil fuels were even discovered ??
