Re: [asa] Creation Care

Actually, it's not all that hard. The climate models are more accurate with respect to sensitivities to changes in various parameters than they are in making absolute predictions. The anthropogenic portion is quite large. Some estimates that I've heard in fact say that all of the warming and more is due to human effects. That is, without any human activity over the last 250 years, we may well be sliding into an ice age. In other words, the range of estimates of the portion of warming that is human-induced is from most of it to more than all of it.
