|"There's no correlation between and temperature"||There is long-term correlation between and global temperature; other effects are short-term.|
The bottom line is that rising temperatures cause carbon levels to rise. Carbon may still influence temperatures, but these ice cores are neutral on that. If both factors caused each other to rise significantly, positive feedback would become exponential. We’d see a runaway greenhouse effect. It hasn’t happened. Some other factor is more important than carbon dioxide, or carbon’s role is minor.

Anthony Cox explains why There IS NO correlation between CO2 and temperature and
so UNSkeptical UNScience (SS) is wrong in saying that there is a long term correlation between CO2 and global temperature.

Michael Beenstock and Yaniv Reingewertz2: Polynomial cointegration tests of anthropogenic impact on global warming
Because the greenhouse effect is temporary rather than permanent, predictions of significant global warming in the 21st century by IPCC are not supported by the data.
M. Beenstock, Y. Reingewertz, and N. Paldor
We have shown that anthropogenic forcings do not polynomially cointegrate with global temperature and solar irradiance. Therefore, data for 1880–2007 do not support the anthropogenic interpretation of global warming during this period.
