Over this past long weekend, spent backpacking in California's Sierra Nevada mountains, I was reminded of a memorable method for distinguishing two of our stateliest trees.

(The bark of Jeffrey pines additionally smells like butterscotch or vanilla, which makes ID'ing them doubly delicious.)

And yet, many in Congress question whether we should do anything about this major threat to public health. The debate took center stage yesterday in a subcommittee hearing of the Senate Environment and Public Works Committee.
