The animal stars of Shark Week, along with the supporting cast of marine life, may be scouting new locations in the north for future editions of the annual celebration of all things shark. A massive new review of evidence suggests that warming causes changes in long-distance marine migrations faster than shifts in the home ranges of plants and animals on land.
Results from 1,735 studies on changes in marine life suggest that more than 80 percent of recent alterations in ocean ecology may have resulted from global climate changes. Nature Climate Change recently published this tremendous analysis of previous studies.
Important links in the ocean food chain, such as phytoplankton, zooplankton and bony fish, moved their ranges an average of 72 kilometers closer to the poles over the past decade.

Spring also springs sooner in the oceans. Spring changes in the ocean arrive more than four days sooner than historical records, which is nearly double the increase observed on land. Zooplankton and larval bony fish were most seriously influenced by this change in spring. Some species had moved up the time table on spring time activities by as much as 11 days.
