Smithsonian Tiger sharks migration patterns are changing due to climate change.
The waters off the northeastern coast of the United States are some of the fastest warming in the world. Human-caused climate change has warmed this part of the Atlantic about 2.7 degrees Fahrenheit since the 1980s.
These rapid, profound alterations have rewired marine ecosystems, causing some species to move into new areas and others to disappear from places they once called home. The cold water habitats favored by Atlantic cod, for example, are predicted to nearly disappear off the coast of New England over the next 60 to 80 years—a shift that will severely complicate attempts to revive the fishery after it collapsed in 1992.
