Discussions on climate change are probably more relevant on the ASA reflector than
here on "evolution". However, now that we are here, let us run with it for a
while, provided the others in the group are happy with it.

It most certainly does. I especially like the three ways you describe the
Christian approach to climate change.
Given that a whole range of human activities -from land clearance to burning of
fossil fuels to animal husbandry - can change climate, how much anthropogenic
change do you believe is too much? Put another way, when do the costs of climate
change out weigh the benefits of the activities which cause the climate change?
What do you see as the responsible way ahead for Christians in science in the area
of climate change?One final question. What is your angle on climate change - do
you approach it from a meteorological, climatological, or geological perspective?
