Seabird world shrinks as oceans warm, forcing longer flights to survive
Researchers said more than 120 seabird species face smaller ranges and longer flights for food as warming oceans outpace their adaptation.
- Researchers at the University of Reading report that warming oceans are forcing seabirds to contract their geographic ranges, according to a study published in the journal Nature Climate Change.
- Today's oceans are warming around 10,000 times faster than historical rates seabirds adapted to over millions of years, accounting for 35% of the variation in range size across the more than 120 species studied.
- Under a worst-case warming scenario, 70 percent of species will reduce their range by 2100, with the Galapagos petrel, the Jouanin petrel, the Newell's shearwater, and the white-vented storm petrel facing real extinction risk.
- Lead author Jorge Avaria-Llautureo said survivors are forced to abandon parts of their range and travel further to find a "new liveable habitat that offers optimal conditions for survival and reproduction."
- Conservation efforts must shift focus from protecting current seabird locations to safeguarding the places they will need to reach in the future, as rapid climate change matters more than whether it gets warmer or cooler.

Seabird world shrinks as oceans warm, forcing longer flights to survive
Seabirds such as albatrosses and petrels are retreating into smaller areas of ocean and traveling further to find new places to live as the climate warms. Scientists from the University of Reading studied more than 120 species of Procellariiformes (the group that includes albatrosses, petrels, shearwaters and storm petrels) using evolutionary family trees, ancient climate records and ocean temperature data to track how their ranges and movements…
