The interaction of climate and the timing of low tides along the West Coast of the United States creates a complex mosaic of thermal environments, in which northern sites can be more thermally stressful than southern sites. Thus, climate change may not lead to a poleward shift in the distribution of intertidal organisms, as has been proposed, but instead will likely cause localized extinctions at a series of "hot spots." Patterns of exposure to extreme climatic conditions are temporally variable, and tidal predictions suggest that in the next 3 to 5 years "hot spots" are likely to appear at several northern sites.
气候与美国西海岸低潮时间的相互作用形成了一个复杂的热环境拼图，其中北部地区的热应激可能比南部地区更严重。因此，气候变化可能不会像人们所提议的那样导致潮间带生物分布向极地转移，而是可能在一系列“热点”地区造成局部灭绝。极端气候条件的暴露模式在时间上是可变的，潮汐预测表明，在未来3至5年内，几个北部地区可能会出现“热点”。
