You're avoiding the question aren't you? Gimme the normal range of climate variation which you must know because you've declared the present to be outside that normal range.
Your question is illogical, and a red herring. I said imbalance. If you understand English- a contentious assertion I realize- an imbalance means a lack of proportion between corresponding things. Like, the energy coming into the planet from space, and the energy that leaves the planet to space.
Normal has nothing to do with the definition of an imbalance.
The reference to your body weight was actually a humorous way of turning your illogical question around. What's been your normal weight over your life time? Probably hasn't been consistent. Yes, just like our climate! But if you consistently take in more energy than you burn, there's going to be a trend. Who cares if it's relative to your 5-10 year old weight, or your 25-30 year old weight? Obviously we care about your current weight more so for things like mitigating risk. Likewise, who cares how much energy came in during the Triassic? It has no relation to our current state, anymore than your weight as a toddler relates to now.
An imbalance in energy into a system and energy out of a system doesn't need a term like normal, in fact it's irrelevant.
Maybe you misunderstood what the term top of the atmosphere energy imbalance means in the climate discussion. Therein lies the problem with folks like you and Colpy-who don't seem to know what the terms are- who think you know better than the people who work in this field.
