With climate change challenging marine biodiversity and resource management, it is critical to anticipate future latitude and depth shifts under contrasting global change scenarios to support policy-relevant assessments of biodiversity impacts [e.g., Intergovernmental Panel on Climate Change (IPCC)].

In this publication we demonstrate the benefits of complying with the Paris Agreement (United Nations Framework Convention on Climate Change) and limiting environmental change, by assessing future distribution shifts of 10 commercially important groundfish species.

We did this throughout the Northern Atlantic Ocean and analyses of distributional shifts compared current conditions (2000-2017) with two representative concentration pathway scenarios (RCPs) for future climate change (2090-2100): one following the climate constraints of the Paris Agreement (RCP2.6) and another without stringent mitigation measures (RCP8.5).

Benefit of the Paris Agreement for fishing targets

We use machine learning distribution modelling with biologically informative predictors to project future latitudinal and depth shifts. Overall, we showed that incorporating biologically informative predictors beyond temperature into species distribution modelling can improve predictive performance, and that limiting future climate change by adhering to the Paris Agreement may translate into reduced distribution shifts, supporting biodiversity conservation and resource management.

Climate change to reshape kelp forest diversity

Climate change threatens to disrupt these underwater havens, but we can take action. Our new research provides a roadmap for conservation, highlighting regions most at risk and where protection efforts are most needed.
