Pro to the question "Is Human Activity Primarily Responsible for Global Climate Change?"
"Climate does change naturally for reasons well understood by scientists. But it does so over thousands or tens of thousands of years – time scales so slow as to be imperceptible to humans…
Human-caused climate changes are different. As the planet’s population has grown to 7 billion people, and as we have learned how to mobilize vast quantities of carbon-based fossil fuels (ironically, created over geologic time scales) to satisfy our short-term energy demands, we have become powerful enough to overwhelm slow geological cycles. We are, for the first time in the 4+ billion year history of the Earth capable of altering the largest geophysical system on the planet – the climate – and we are doing it on a human time scale of years and decades, with consequences we are only just beginning to comprehend. And ironically, our effect on the climate is still slow enough for policy makers, climate contrarians and skeptics, and those simply not paying attention to either actively deny it or to just look the other way, committing the planet to more and more change…
[T]he inability to comprehend the planetary influence of humans isn’t based on reviewing and rejecting the scientific evidence, which is clear to 97-98% of climate scientists publishing in the field. It is based on ignoring or disbelieving it."
