We should be. Why? Because reasonable estimates of the amount of extra energy contained within the atmosphere due to anthropogenic effects are in the single digit petawatt range. It's a number everyone should be carrying in their heads.
Put a different way: the total annual harvestable solar yield is within an order of magnitude of the energy we've caused to accumulate inside the atmospheric boundary. Think about that, for a second or two.
