However, the most
important element in this analysis is that both will do well because their
qualitative attributes will be better valued in a reformed market that better differentiates between the environmentally and operationally
qualitative aspects of competing power sources.
We have formulated a much broader definition of a tipping
element, because (i) we wish to include nonclimatic variables; (ii) there may be cases where the transition is slower than the anthropogenic forcing causing it; (iii) there may be no abruptness, but a slight change in control may have a
qualitative impact in the future; and (iv) for several
important phase changes, state - of - the - art models differ as to whether the transition is reversible or irreversible (in principle).
