In a detailed review of science for the Global Warming Policy Foundation, Dr Christy summarised with three main points: "1. Theoretical climate modelling is deficient for describing past variations...They’ve failed hypothesis tests and that means they’re highly questionable.
"2. The weather we really care about isn’t changing, and Mother Nature has many ways on her own to cause her climate to experience considerable variations in cycles. "3. Carbon is the world’s dominant source of energy today, because it is affordable and directly leads to poverty eradication as well as the lengthening and quality enhancement of human life.
