Figure 1 Contemporary climate changes affect the geographical distribution of a number of species of terrestrial and marine organisms. Grebmeier et al. (p. 1461) observed responses to climate change in an entire ecosystem, the northern Bering Sea. This ecosystem is relatively shallow, with a rich benthic prey source that supports bottom-feeding marine mammals and seabirds that are hunted by local human populations. During the past decade, there has been a geographic displacement of marine mammal population distributions northward, a reduction of benthic prey populations, an increase in pelagic fish, a reduction in sea ice, and an increase in air and ocean temperatures.
