A Spectacular Failure: Latest Temperatures Significantly Below Model Predictions
Not only are U.S. temperatures below climate model predicted values, but global temperatures are also not behaving in the mode of the "consensus" IPCC climate models that represent the supposed 97% of scientists who say climate science is "settled."
Directcomparison IPCC vs Hadcrut UAH The actual temperatures (bright green curve for UAH-NASA satellite and bright blue curve for HadCRUT) shown in this chart are compared to the various IPCC scenarios of CO2 emissions. The orange curve ('commitment') was the IPCC climate model temperature scenario that assumed CO2 emissions would "stabalise" at levels for year 2000. The darker blue, green and red curves represent different growth scenarios of "business as usual" CO2 emissions.
As is clear in the chart, global temperatures are significantly below even the the IPCC scenario of stabilized (orange curve) CO2 emissions. This is a spectacular failure, confirming that increasing CO2 emissions are not driving temperatures up, despite the "consensus" science. It also confirms how worthless climate models are for policymakers to rely on as predictive tools.
As this next chart indicates, global CO2 emissions (tons) continue to grow with 2010 levels substantially above the 2000 CO2 emission levels. Clearly, the CO2 growth continues at the pace of the IPCC's "business as usual" terminolgy.
