Dear MARMAM Community, Scientists at the U.S. Marine Mammal Commission have published a review<https://www.mmc.gov/effects-of-climate-change-on-marine-mammals/> of the evidence for effects of climate change on marine mammals that occur in U.S. waters. Climate change impacts on Arctic marine mammal are best known, but have also been documented throughout US waters, including temperate and sub-tropical regions. While many of the observed effects had been predicted, some unforeseen effects have also been documented, such as the dramatic loss of pupping/nursing habitat for endangered Hawaiian monk seals due to sea level rise and severe storms. Many suspected effects of climate change remain unconfirmed; modifications to research and monitoring efforts could reveal the full scope and significance of current and future impacts on marine mammals. Commission scientists concluded that detecting and mitigating the threats to marine mammals from climate change will require some realignment of research and monitoring priorities, coupled with rapid and flexible management that includes both conventional and novel conservation interventions. The Commission’s current request for grant proposals focusing on climate change effects on marine mammals remains open until April 13.

A review of climate change effects on marine mammals in United States waters: Past predictions, observed impacts, current research and conservation imperatives. Climate Change Ecology 3:100054. Abstract: We consider the current evidence of climate change effects on marine mammals that occur in U.S. waters relative to past predictions. Compelling cases of such effects have been documented, though few studies have confirmed population-level impacts on abundance or vital rates. While many of the observed effects had been predicted, some unforeseen and relatively acute consequences have also been documented. Effects often occur when climate- induced alterations are superimposed upon marine mammals’ ecological (e.g., predator-prey) relationships or coincident human activities. As they were unanticipated, some of the unpredicted effects of climate change have strained the ability of existing conservation and management systems to respond effectively. The literature is replete with cases suggestive of climate change impacts on marine mammals, but which remain unconfirmed. This uncertainty is partially explained by insufficient research and monitoring designed to reveal the connections. Detecting and mitigating the impacts of climate change will require some realignment of research and monitoring priorities, coupled with rapid and flexible management that includes both conventional and novel conservation interventions.
