Continued warming of the Earth's oceans over the next century could trigger disruptions (引起毁坏) to marine life on a scale not seen in the last 3 million years, scientists warn in a study released Monday.
The changes could (1)_______ extinctions of some of the ocean's keystone species as well as plants that (2)_______ to new territory because of changing environmental conditions, the report says.
But the most dramatic disruptions would likely be (3)_______ if the world's nations can bring greenhouse gas emissions under control in the (4)_______ decades, the authors write in the scientific journal Nature Climate Change.
"Climate change may rapidly reorganize marine diversity over large oceanic (5)_______," states the report, authored by scientists from the University of Science and Technology in Lille, France, and four other institutions. "The (6)_______ of this reorganization will depend, unsurprisingly, on the magnitude of warming."
In the study, the researchers seek to predict future (7)_______ of global warming on marine life by examining how the oceans were affected during times of substantial temperature change in the (8)_______ past. Using fossil data, scientists have been able to reconstruct patterns of extinction and species migration that (9)_______ 3 million years ago during the mid-Pliocene epoch, when the Earth was (10)_______ warmer than today. Similar data exists for the last Ice Age, which reached its peak about 25,000 years ago.
