Os modelos matemáticos que servem de base de cálculo das séries de medições de temperatura do planeta usam tantas e tão subjetivas variáveis que é difícil acreditar nos resultados. Na peça referenciada até parece que se adicionam ou alteram coeficientes com o propósito de atingir resultados pré-definidos.
"Christy notes, "If you want to say model trends are bolstered, you must remember model trends are all over the map. Which trend is bolstered? Perhaps you want to say those model trends less than 0.2 C per decade are bolstered." Right now the available data sets appear to strengthen the case for arguing that the lower-end model projections for future temperature increases are more likely ones. Christy concludes, "The new warming trend is still well below ideas of dramatic or catastrophic warming."
