lotta good debate here, I have not seen the data on the rise of the other planets but I can tell you that their temperatures have not drasticaly started to rise in the past hundred years. and yes our planet goes through changes but these changes have been drasticaly speed up in the past hundred years or so. I am sure this is not the first time this planet has seen the green house effect but I dont think this time it was a natual occurance. But wether it is man or natual made, people are debating if it is even real. that is what we have to think about now. In the next 300 to 500 years we could be in another ice age, what ever the case is drastic changes are going to occur, such as deserts turning to forest, forests to deseerts, flooding, etc. We are starting to see species like frogs and deep sea creatures, die off or come into exsistance (how ever you want to think of it). these are all proof that the climate is drasticaly changing. The blame doesnt matter any more, the shit has hit the fan and no matter who or where you are your gonna get sticky eventualy.
