However, he pointed out that such migrations had occurred over hundreds or even thousands of years, and that the current rate of global warming was generally faster.
"It's also important to keep in mind that coral reefs and coral reef ecosystems are far less likely to survive other stressors, such as overfishing and pollution, when it is not possible to survive. they live in marginal habitats, "the researchers wrote.
"In addition, our projections … can be relatively optimistic in the face of anthropogenic climate change because they do not take into account the impacts of ocean acidification."
But the researchers said the fossil record could be a valuable tool for predicting how reefs could react to climate change.
Scientists participating in another study found that large scale reef changes were visible from space.
Australian and international researchers took the opportunity to use satellite images of Google Earth during grazing halos.

The large plant configurations show where the fish eat and can be seen from the space.
Researchers can use these halos to assess the health of marine life and, by extension, to detect and predict changes in reef ecology around the world.
"This approach demonstrates that we can now detect some aspects of the ecological responses of reefs to protection, even in remote and inaccessible reefs on a global scale," the researchers wrote.
"To quantify the effectiveness of the world's marine reserves, we need to go beyond current methods to adopt more scalable and cost-effective approaches, including satellite observation of the world's reefs may be one."
The research was published in the journal Acts of the Royal Society B.
