The world is warming and there appears to be no warming end in sight. Scientists across the globe have been studying the occurrence of global warming and the consequential impacts of such warming for years. Such research has giving us a plethora of information in order to make changes to slow warming. However, despite some efforts, most scientists agree that warming has yet to even begin to slow.
Therefore, many expect immense species extinction to occur in the coming decades due to global warming. This has led many scientists to compare the potential extinction to come to past known extinctions on a global scale. John Alroy, who is a researcher for the Department of Biological Sciences a Macquarie University, is one of these scientists.
Alroy studied the past Permian-Triassic Extinction Event which occurred 250 million years ago. His complete findings were then published in the journal Science. In order to do his research, Alroy used fossil data from the Paleobiology Database. Alroy studied mainly marine fossils, namely corals and brachiopods.
Alroy concluded that regardless of the prolific and diverse nature of a particular species, there is no way to predict whether the species will survive. Corals survived the mass extinction 250 million years ago, despite massive losses. Coral eventually recovered to previous levels. However, brachiopods, which were as prolific and diverse as coral, did not fare as well. While they are still in existence today, they are limited and not diverse.
Alroy points to the corals of today not potentially recovering like their counterparts 250 million years ago. Alroy suspects due to today’s corals sensitivities to changes, they may no longer be the main reef builders years from today. This niche would most likely be taken up by sponges and clams, that is if their numbers are able to fill such a niche.
The fact that such an extinction has never before been seen by humans, Alroy points to the potential outcomes as nearly impossible to determine with any certainty. However, he did allude to the fact that we would be witnessing an extinction of our own doing.
Alroy stated: “We’re 100 percent responsible for it. There is no precedent at all for what we’re doing. All well-understood extinctions in the deep fossil record are tied to environmental changes that were not triggered by the behavior of individual species, such as the asteroid impact 65 million years ago that wiped out the terrestrial dinosaurs.”
