Most people know the old adage “when all you have is a hammer, everything looks like a nail.” How does that saying apply to Climate Science? While, in 2001, the UN IPCC’s Third Assessment Report (TAR, 2001) conceded that “climate study should focus on factors which may affect climate change during the next century,” there is really only one factor today that matters to Climate Modellers and policy-makers alike – CO2. How did that happen?  Following the embrace of Mann’s Hockey Stick graph and prior to the release of the Fourth Assessment Report (AR4, 2007), the United Nations Framework Convention on Climate Change (UNFCCC) narrowed the focus and research funding for Climate Change. They redefined it in Article 1 of the UNFCCC to be “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over considerable time periods.” Is it any wonder that Climate Modellers have failed dismally at predicting future global temperatures? Their models were all crippled from birth as forcing assumptions betrayed any pretence of neutrality. They shout “it’s all about the greenhouse, baby” while natural drivers like the sun are written off as being trivial.
