1) Global warming is man-made.
to think that global warming isn't impacted by man is to be just stupid at this point. Political mis interpetations of the facts in the media (including the blogosphere) not with standing it is happening.
Yes global climate is effected by repeating cycles La Nina, pacific cascadal, etc.
Response: Why? Because "scientific consensus" says it is so? Well, when climatologists and meteorologists are punished because they questions the **dogma**, then I seriously question the dogma. Being a scientists means being a skeptic and testing a hypothesis. The simple fact that "scientists" have so quickly, seemingly by vote, decided that global climate change is happening and that it is man-made brings serious doubts to me All I hear is, since the history of recorded weather patterns, our planet is the warmest it has ever been. Okay, but how long have we had records that can be considered accurate and precise? 100 years? 150 years? At most 200 years in a planetary history that spans millions of years? Are we sure those 150 years were an accurate representation of the Earth's normal climate? I mean, we only recently (relatively speaking) came out of an ice age. Sort of makes sense that we would be warming up...
Because Barack Obama and Al Gore say that the debate is over? They're **experts** on global climate change~ I understand this. But give me a break. The debate is NEVER over in science.
2) Yes, man could change it in either case, however I am not sure we should.
as a FYI,. the amount of light that hits the ground has lessened measurable over the last 50 years. So there are two things happening the effect global climate change.
No, these two factor don't 'balance' each other out, warming is stronger then the cooling effect caused by dimming.
I bring this up becasue adding a cooling 'terra forming' to this may be pretty catastrophic.
The only problem with Global climate change is that it's more complex then a post or media blurb can say , and more then most people are willing to try and grasp. AS has been shown conspiracies are generated from people who don't understand a complex subject, so the fall back on some 'invisible' entity as an explanation.
In any case, the most simple risk assessment shows we should be spending money on this. Even money spent on dealing with a non preventable global warming is needed to offset the Trillions of dollars of damage that will occur.
Response: If the damage is non-preventable then how are you offsetting damage that will unavoidably occur? Better to divert the money to things we can actually impact than waste it on something we can't.
