This is great, but why are these tools only for the Pacific Northwest?

Built by a climate lab out of the University of Idaho.

Many are available for the US as a whole (eg. estimation of future plant hardiness zones). The climate graph generator is available for any land location globally.

Well, why would you expect them to be global?

Take your pick: Geographically-bound datasets, stakeholders which are distinctly regional in their operations and funding, idiosyncratic local climate patterns...
