The project of Buddhism is about one thing: liberation from the suffering caused by greed, hatred, and delusion.  For most Buddhists, then, scientific controversies must be framed in light of suffering, wisdom, and compassion.  The goal of most Buddhist practice is to see things clearly, just as they are, without overlay of story, view, habit, or delusion.  

Seeing things clearly includes the recognition of some basic facts of existence: all things arise due to causes and conditions, and when those conditions cease, so does the thing caused by those conditions; we are interconnected; everyting is impermanent; to be human means to experience the pain of old age, sickness, and death; and our sense of a separate, inherent and fixed self is an illusion. 

Seeing things clearly also involves the recognition that our tools for knowing the truth are limited.  Such recognition works against the hubris of thinking we have everything figured out.  In terms of global warming, it seems to me that recognizing our limitations means that we must procede with caution as we layer human constructions and systems on top of the non-human world.  It means erring on the side of caution.  It means erring on the side of all life, all sentient beings.  It means subordinating greed to life. 

In short, seeing things clearly requires deep awareness and attention, freeing the mind from presumption and the grasping attachement that manifest as greed.  Seeing things clearly means acting with compassion and humility, trying to open to the wisdom of what to do right now.
