Executive summary

Nick Graham, a marine ecologist at Lancaster University, led a 28-island study published in Science Advances showing that healthy atoll ecosystems can adapt to rising seas. The findings give island nations a scientific basis for investing in ecosystem restoration as a climate adaptation strategy.

Seabird guano is doing more than fertilizing soil - it may be helping entire islands survive climate change. A new study in Science Advances, led by Nick Graham, a marine ecologist at Lancaster University, analyzed 28 atoll islands across the Pacific and Indian Oceans and found that healthy ecosystems can help these landforms keep pace with rising seas. The paper, published Wednesday, describes atoll islands as "naturally active systems that can change and adapt to their environmental conditions if they are allowed to do so."
