To support the shelf properly, you should build support all the way down to the buildings footings.

Whatever the route, I can say with great confidence that the wall does provide a load path all the way down to the footings. Adding a floating shelf puts a relatively small bending moment on the wall at the anchor points, that's all.

Furthermore, you'll need to get a building permit and have the shelves inspected by the AHJ.

Failure to comply could result in fines and your insurance company could refuse to pay the claim if your house falls over.
