Things are not better down there.
According to a study published Thursday in the journal Science, ocean life is in the most danger since an asteroid killed off the dinosaurs 66 million years ago.
The researchers behind the paper said in a press release that if current carbon emissions levels go unaddressed, tropical zones could see biodiversity loss and polar zones could suffer mass extinction as marine life runs out of oxygen.
As greenhouse gas emissions continue to warm the world's oceans, marine biodiversity could plummet to levels not seen since the extinction of the dinosaurs, according to a release.
The findings echo the protests other scientists have made over government inaction to stop climate change.
According to the study co-author, extreme warming will lead to climate-driven extinctions that will rival all current human stressors combined.
The researchers say there is still time to prevent the worst extinction scenarios.
Penn said that the future isn't written in stone.
Efforts at clean energy are picking up, even though we might not be moving fast enough. We hope we can close the gap before we have to see if the study is correct.
