Greenhouse gas emissions could trigger a mass extinction of marine life to a level not seen since the time of the dinosaurs. This is stated in a new study by scientists from New Jersey, writes the Daily Mail.
The researchers modeled the future risks of extinction of inhabitants in all the oceans of the world under various predicted climate scenarios. They found that as emissions increase, biodiversity loss increases in tropical waters, in while polar species are at the highest risk of extinction.
But scientists remain optimistic: “The scale of extinction we've found depends heavily on how much carbon dioxide we emit as we move forward into the future. We still have enough time to change the trajectory of emissions and prevent the extent of warming that could trigger the predicted mass extinction. Justin Penn of the Department of Earth Sciences at Princeton University says so.
Water temperature and oxygen availability are two key factors that will change as the climate warms due to human activity. greenhouse gases could reduce the risk of extinction of marine life by more than 70%.
