Of course they apply but how and to what extent? CO2 is a GHG and we expect some warming in relation to its level. Where is the empirical data unambiguously linking CO2 production and levels to Anthropogenic global warming?

Currently we are talking about endless massaged data from various sources generating a global composite temperature of +0.28 C (about 0.50 degrees Fahrenheit) above the 30-year average for August in an El Nino year.
