Warming Waters Inhibit Fish from Reproducing
As many as 60 percent of the world’s fish species could struggle to breed and reproduce if climate change causes the Earth to warm by 5 degrees Celsius over the next 80 years, the current projection for what will happen if greenhouse gas emissions continue unchecked, according to a new study.
A study released Thursday in the journal Science that examined nearly 700 species of freshwater and saltwater fish found that 6 in 10 species would be affected if bodies of water around the world continue to warm. If global warming was limited to 1.5 degrees Celsius, the study’s authors added, that number falls as low as 1 in 10 species.
Species unable to reproduce in traditional habitats may either move to deeper water or further north and would result in local extinctions.
