Yeah, and I'm supposed to be an aeronautical engineer and I still had some problems to get my mind around that....
So don't worry, you're not the only one!
Since we have shown (some disagree) that in climb, required lift is lower...
Nope....
The "lift",
in the sense of the vertical force needed to counter gravity is exactly the same as the aircraft weight (we're talking a steady-state climb).
So the force provided by the wing, which force is now tilted back by the climb angle, now has to be larger (the upwards force provided by the thrust is an order of magnitude smaller).
To increase that force, the AoA has to be larger.
