CO2 lags temperature by 5 months, Nature study 1990, followup NASA 2009 study finds CO2 lags 15+ months. John Boehner and Mitch McConnell ignore this to keep the multi-trillion dollar climate scare gravy train going

Feb. 22, 1990, "Coherence established between atmospheric carbon dioxide and global temperature," Nature.com

Mathematical Sciences Research Center, AT&T Bell Labs, Murray Hill, New Jersey 07974, USA. Cynthia Kuo, Craig Lindberg & David J. Thomson

"The hypothesis that the increase in atmospheric carbon dioxide is related to observable changes in the climate is tested using modern methods of time-series analysis. The results confirm that average global temperature is increasing, and that temperature and atmospheric carbon dioxide are significantly correlated over the past thirty years. 

Changes in carbon dioxide content lag those in temperature by five months."

==================================

Fall 2009, NASA followup study funded by US taxpayers, says CO2 lag time may be longer, that oceans may hide/effect some heat:

"A Re-evaluation of the Coherence Between Atmospheric Carbon Dioxide and Global-Average Temperatures at Interannual Time Scales," Park, J. J.

American Geophysical Union, Fall Meeting 2009, abstract #GC24A-02
Frequency-dependent coherence between atmospheric CO2 and historical temperatures reveals climate feedbacks within Earth's carbon cycle. Kuo et al (1990) showed that CO2 lagged global-average temperatures by 5 months at interannual periods during 1958-1988, but this relationship has changed over time. Since 1979, at Mauna Loa and other observation sites, interannual coherence exhibits a 90o phase lag that suggests a direct correlation between temperatures and the time-derivative of CO2, not a simple time-lagged response. The coherence transition can be explained if the response time of CO2 to global temperature fluctuations has lengthened from 5-6 months to at least 15 months. This longer response time may reflect saturation of the oceanic carbon sink, but a transient shift in ocean circulation may also play a role.
Coherent annual-cycle fluctuations in CO2 and temperature are evident in the 1958-1988 time series, but not the 1979-2008 interval. Coherence of CO2 with gridpoint temperature anomalies suggests that interannual temperature-CO2 correlations are dominated by the tropical oceans. The large influence of the terrestrial biosphere on atmospheric CO2, therefore, is not mediated significantly by interannual temperature anomalies. Kuo, C., C. Lindberg, and D. J. Thomson (1990), Coherence established between atmospheric carbon dioxide and global temperature, Nature, 343, 709--714.

In 2012 $1 billion a day was "invested" in the notion of global warming.

Real problems were left to starve.
