A new study in the journal Ecology suggests that last year's heat dome over the west coast of B.C. and Washington state may have "far-reaching" effects on the ecology of beaches, bluffs, inlets and river deltas, in addition to the impact on fisheries and cultural connections that the land, sea and sea life provide. The heat that descended on the West Coast last June not only killed 619 people, but also roughly a billion sea creatures, which baked to death as temperatures soared.
