The new IPCC Special Report, released today, is the first IPCC Report to focus on the role of the ocean in the global climate and the effects of climate change on the ocean. Ocean acidification is extensively covered throughout the report. A few OA-relevant excerpts from the Summary for Policymakers

Ocean acidification and hypoxia plan outlines Oregon’s commitment to addressing climate impacts
CORVALLIS, Ore. – Oregon has a new roadmap for addressing rising ocean acidification and hypoxia – two climate change-induced conditions that could have widespread consequences for the state’s ocean ecosystem and the economy. Ocean acidification and hypoxia are significant threats to a wide range of marine mammals, from crabs to
The dynamics and impact of ocean acidification and hypoxia: insights from sustained investigations in the Northern California Current Large Marine Ecosystem
Coastal upwelling ecosystems around the world are defined by wind-generated currents that bring deep, nutrient-rich waters to the surface ocean where they fuel exceptionally productive food webs. These ecosystems are also now understood to share a common vulnerability to ocean acidification and hypoxia (OAH). In the California Current Large Marine
Effects of multiple climate change stressors on gene expression in blue rockfish (Sebastes mystinus)
Highlights Marine fishes will be exposed to multiple stressors under climate change. Hypoxia and high pCO2 are both expected to cause shifts in energy metabolism. No signs of energetic shifts were observed at transcriptomic or enzymatic levels. Multiple stressor transcriptomes are not predictable based on responses to single stressors. Blue
Biogeochemical anomalies at two southern California Current System moorings during the 2014‐16 Warm Anomaly‐El Niño sequence
We analyzed impacts of the 2014‐15 Pacific Warm Anomaly and 2015‐16 El Niño on physical and biogeochemical variables at two southern California Current System moorings (CCE2, nearshore upwelling off Point Conception; CCE1, offshore California Current). Nitrate and Chl‐a fluorescence were < 1 μM and < 1 Standardized Fluorescence Unit, respectively,
