How many lives has climate science saved?

As PM Turnbull wings his way to Paris for the 21st yearly session of the Conference of the Parties to the 1992 United Nations Framework Convention on Climate Change, this one known as ‘Paris 2015’, he should ask himself a simple question. How many lives has climate science saved? In contemplating the question he should consider that since 1989 the United States Global Change Research Program (GCRP) has dispensed almost US$45 billion on climate science (Congressional Research Service, Federal Climate Change Funding).
