Fish will have to find new habitats or perish if global warming is left unchecked

Media Release | July 2, 2015
[font size=3]Climate change is forcing fish out of their current habitats and into cooler waters and many more species will soon be affected if climate goals are not met, say scientists.
An international team of researchers compared the future of the oceans under two climate change scenarios. In one scenario, we limit atmospheric warming to two degrees by 2100, as outlined by the Copenhagen accord. In the other, we continue with the current approach, which researchers say would cause a five-degree increase in atmospheric temperatures. They say if warming continues unchecked, fish will migrate away from their current habitats 65 per cent faster, resulting in changes to biodiversity and ecosystem functions.
The new research, published today in Science, points to the need to limit emissions to help reduce the impact of rising atmospheric temperatures and acidifying oceans. The findings are intended to inform discussions at the upcoming 2015 United Nations Climate Change Conference in Paris.
“All the species and services we get from the ocean will be impacted and everyone, including Canadians, who benefit from these goods and services are vulnerable,” said William Cheung, associate professor and co-director of the Nereus Program at UBC. “On a positive note, we still have options to substantially reduce these impacts now but the longer we wait the fewer and fewer options we have.”
