Do you honestly believe we have any actual power over the climate? It seems like a very arrogant opinion to assume we, as a species, can have any appreciable, long lasting effect on our planet. I suspect (my own personal opinion that I will not provide references for) that our climate is absolutey changing and the change seems to be accelerating, I'm not convinced that it's our fault. We can't even figure out our own origins on this planet (that was here for billions of years before us), and we think we somehow understand and are responsible for its well being. In todays popular vernacular "virus" is a very popular term, it has been applied to any number of things by any number of people, it might be computers, politics, education, agriculture or our health. All of those things are specifically related to our well being, but what if on a larger scale we are a virus on this planet? I wish it was a garden of eden but it's not, I suspect the dinosaurs felt the same way. I've said in the past that I'm not a huge fan of the sun, my northeastern European heritage has left me decidedly ill-prepared to scamper around under its constant attack and I have a very odd love/hate relationship with it, I love it when it's out and I'm in the shade and I hate it's direct assault. This planet isn't going anywhere, we as a species might or might not. Even in our relatively short time on this whirling dervish we, as a species, have managed to survive a few of these major climate changes in the past more than once. If you're worried about the species, don't, there's nothing you can do about it anyway. If you're worried about your grandkids I don't know what to tell you, I never reproduced.
