Recent Advances on Application of Modified Biochar for the Removal of Pharmaceutical Compounds from Wastewater

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
Modified biochar is an effective adsorbent for removing pharmaceutical contaminants from water. Physical and chemical modifications enhance its surface area, porosity, and functionality, enabling multiple adsorption mechanisms. These synergistic interactions improve removal efficiency.

Charting a Transformational Course Toward a Safe and Just Future: The Earth Commission's Contribution

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract Humans are now operating well outside the planetary conditions under which social and economic development has been possible. A precondition for securing equitable access to this prosperity is to safeguard the stability of the Earth system. The situation is urgent—we need a swift and profound shift in direction—a collective transformation.

Ocean deoxygenation: Past, present, and future

open access: yesEos, Transactions American Geophysical Union, 2011
To a first order, the oxygen content of the ocean interior is determined by the influx of the gas across the air‐sea surface (i.e., ventilation) and consumption due primarily to microbial respiration. As these two competing processes vary in space and time, so does the concentration of oxygen in the ocean interior.

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Geoengineered ocean vertical water exchange can accelerate global deoxygenation [PDF]

open access: yes, 2020
Ocean deoxygenation is a threat to marine ecosystems. We evaluated the potential of two ocean intervention technologies, i.e. “artificial downwelling (AD)” and “artificial upwelling (AU)”, for remedying the expansion of Oxygen Deficient Zones (ODZs). The

Deoxygenation in warming oceans--Looking back to the future [PDF]

open access: yesGeology, 2012
671 Earth’s climate has varied dramatically over its long history, from snowball glaciations to greenhouse extremes. Ancient warming is one reason we study the past—to get the fullest possible picture of what might lie ahead. No episode of past warming was more dramatic than the Paleocene-Eocene Thermal Maximum (PETM) ~55 m.y.

Climatic controls on metabolic constraints in the ocean [PDF]

open access: yesBiogeosciences
Observations and models indicate that climate warming is associated with the loss of dissolved oxygen from the ocean. Dissolved oxygen is a fundamental requirement for heterotrophic marine organisms (except marine mammals) and, since the basal metabolism

Historical Range Contraction and Extent of Harbour Porpoises (Phocoena phocoena) in the Baltic Sea Revealed by Archival Newspapers

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Archival Swedish newspapers from the 18th to 20th centuries reveal that the Baltic harbour porpoise once utilized the waters along the full Swedish coast, reaching far north into the Gulf of Bothnia, areas where it no longer occurs today. These records show a major range loss and highlight the importance of historical baselines for conservation ...
