Study Notes Potential Impact of Climate Change on Maritime Boundaries

A new study released Sept. 12 by University of Sydney researchers concludes that the rules for atolls and coral reefs in international law of the sea, already subject to interpretation due to their shifting nature, will be under greater stress as sea levels rise and ocean acidification disrupts reef integrity. These reef islands, found across the Indo-Pacific are already growing and shrinking due to complex biological and physical processes yet to be fully understood, and now climate change is leading to new uncertainties for legal maritime zones and small island states, according to the study, which was published in Environmental Research Letters. Thomas Fellowes, a postdoctoral research associate at the university and the lead author of the paper, called the situation “a perfec...

UBC Urges Strong Action to Mitigate Climate Change

A new study released by the University of British Columbia is projecting the impact of different global temperature increases and ranges of fishing activity will have on biomass, or the amount of fish by weight in a given area, from 1950 to 2100. The simulations suggest that climate change has reduced fish stocks in 103 of 226 marine regions studied, including Canada, from their historical levels, and that these stocks will struggle to rebuild their numbers under projected global warming levels in the 21st century. According to lead study author William Cheung, a professor at Canada’s Institute for the Oceans and Fisheries, more conservation-oriented fisheries management is essential to rebuild over-exploited fish stocks under climate change. But that alone is not enough, Cheung ...

NOAA Extends Comment Period on Draft Climate Science Action Plans

Federal fisheries officials have extended to Friday, July 29, the deadline for comments on the proposed NOAA Climate Science Regional Action Plans to make fisheries and protected resources more resilient to climate change. Copies of the draft regional action plans are available for the Western Region, including California, the Beaufort and Chukchi seas, Eastern Bering Sea and Gulf of Alaska. The initial Western Regional Action Plan, released in 2016, focused on implementing NOAA Fisheries’ Climate Science Strategy (NCSS) in the California Current Large Marine Ecosystem over three to five years. The current draft builds on previous efforts and describes proposed actions in 2022-2024 to provide decision makers with information to prepare for and respond to changing conditions in th...

Study: Climate Change Results in Fewer Productive Fish Species

A new Rutgers University study finds that as temperatures warm during climate change, predator-prey interactions could prevent some species from keeping up with conditions where they could thrive, resulting in fewer productive fish species to catch in the future.  The study, published April 13 in the biological research journal Proceedings of the Royal Society B, presents a mixed picture of ocean health. Not only could large species and commercially important fisheries shift out of their historical ranges as climate warms, but they would likely not be as abundant even in their new geographic ranges. For instance, a cod fisherman in the Atlantic might still find fish 200 years from now but in significantly fewer numbers.  According to study coauthor Malin Pinsky, the findings sugg...
