Assessing Mediterranean Sea temperature and salinity trends using Argo float data and reanalysis products between 2012 and 2025
A recent study rigorously assesses Mediterranean Sea temperature and salinity trends from 2012 to 2025, leveraging data from Argo floats and reanalysis products across three key basins. Findings reveal consistent warming, particularly in the Western Mediterranean and Ionian Sea, alongside salinity fluctuations influenced by North Atlantic freshening. Notably, subsurface salinification is also observed. While discrepancies exist due to data density, both datasets confirm ongoing warming and salinification, underscoring the impact of climate change.
Editorial: The threat of invasive alien species and the challenge of climate change
## Editorial: The Threat of Invasive Alien Species and the Challenge of Climate Change The escalating impacts of climate change are not occurring in isolation; they are synergistically amplifying the threat posed by invasive alien species. Altered ocean temperatures, shifting currents, and increased storm frequency create unprecedented opportunities for non-native organisms to establish and proliferate, disrupting fragile marine ecosystems. Addressing this complex interplay demands integrated data and rigorous analysis.
Disentangling the structure of an Antarctic plankton food web in bloom and non-bloom conditions
Understanding Antarctic marine ecosystems requires a clearer picture of plankton food web dynamics. This study, utilizing a network-based approach, disentangles these trophic relationships in Potter Cove under both phytoplankton bloom and non-bloom conditions, drawing on a 30-year longitudinal dataset. Findings reveal increased food availability for higher trophic levels during blooms, while microzooplankton play a crucial role in energy transfer during non-bloom periods.
Sandy littorals under threat: a comprehensive review of the impacts of climate change on plant-dominated components relevant to the Mediterranean littoral active zone
Climate change poses a significant threat to Mediterranean sandy littorals, impacting plant-dominated components critical for coastal resilience. This comprehensive review synthesizes existing literature on the effects of warming, acidification, sea-level rise, and other climate-induced stressors on seagrasses, wrack, and dune plants within the surf zone, beach, and foredune. Notably, research often isolates stressors, neglecting the complex interplay of multiple factors.
Copernicus Marine and Copernicus Climate Change: Daily global sea surface temperatures break records for the time of year | Copernicus - Copernicus Climate
Daily global sea surface temperatures have reached unprecedented levels, surpassing records for this time of year, according to data from Copernicus Marine and Copernicus Climate Change. This represents a significant climate indicator, validated by continuous, real-time monitoring across the globe. The integrated data ecosystem provides empirical evidence of warming trends, underscoring the urgency of ocean stewardship and the need for collaborative action.
PHYS.Org: Researchers link the mass extinction of once-dominant marine groups to intolerable heat, diminished oxygen in oceans
A recent peer-reviewed study published in *PNAS* establishes a critical link between past marine mass extinctions and periods of extreme ocean warming and oxygen depletion. Researchers have identified intolerable heat and diminished oxygen levels as primary drivers in the decline of once-dominant marine groups. This longitudinal analysis provides further validated evidence supporting the vulnerability of ocean ecosystems to climate change, emphasizing the urgency of understanding and mitigating current climate indicators for effective ocean stewardship.
