A post from @giffmana is pushing the claim that California walnuts use 20 times more water than all U.S. data centers, but the visible sourcing here is still thin. The clearest read, for now, is the attributed one: this is what the post says, how it is being framed on X, and what still is not established well enough to treat as settled. Readers can see the claim, who surfaced it, and where the missing source context starts to matter.
