I don't know, what you said is pretty confusing. Either the temperatures are increasing or they're not. Either CO2 is retaining heat and increasing temperatures or it's not. But ocean surface temperatures are 0.9°C warmer whereas temperatures over land are 1.9°C warmer. And the Arctic is warming at least three times faster than the globe as a whole since the mid-1990s primarily due to the "ice-albedo feedback" where the melting of sun-reflecting ice results in more heat absorption.
