Misrepresentation of Human Climate Fingerprint in DOE Report

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract A July 2025 report from the U.S. Department of Energy (DOE) made the key claim that the stratosphere has warmed since 2000, contrary to model projections and inconsistent with the expected anthropogenic fingerprint. The DOE report provided no references or data to support this claim.

Out of the blue: Volcanic SO2 emissions during the 2021–2022 eruptions of Hunga Tonga—Hunga Ha’apai (Tonga)

Frontiers in Earth Science, 2022
Most volcanism on Earth is submarine, but volcanic gas emissions by submarine eruptions are rarely observed and hence largely unquantified. On 15 January 2022 a submarine eruption of Hunga Tonga-Hunga Ha’apai (HTHH) volcano (Tonga) generated an explosion of historic magnitude, and was preceded by ∼1 month of Surtseyan eruptive ...

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.

Once despised now desired: innovative land use and management of multilayered Pumice Soils in the Taupo and Galatea areas, central North Island, New Zealand [PDF]

, 2014
The tour brings together innovative land use change and management associated with dairy farming, and land-based effluent disposal, on weakly weathered and multi-layered, glass-rich, Pumice Soils (Vitrands) in the Taupo and Galatea areas.

High temperature SO2 chemisorption on model systems. Implications for in-plume processes. [PDF]

, 2010
Volcanic volatile species are scavenged by silicate ash during transition through eruption plumes. Scavenging may form S, F and Cl salts and acids on ash surfaces, though the mechanisms and controlling variables remain poorly understood.

Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

No Place to Hide? Regional Resilience and Vulnerability to Global Catastrophic Risk

Global Challenges, Volume 10, Issue 8, August 2026.
No location on Earth withstands every global catastrophe. This review maps the geographic, institutional and infrastructural factors shaping resilience to nuclear, volcanic and impact winters, infrastructure loss and pandemics. Geographic isolation, food self‐sufficiency, strong governance and decentralization improve resilience across scenarios ...

Concentric Traveling Ionospheric Disturbances (CTIDs) Triggered by the 2022 Tonga Volcanic Eruption

Journal of Geophysical Research: Space Physics, 2023
AbstractThis paper investigates concentric traveling ionospheric disturbances (CTIDs) associated with the Tonga volcanic eruption. Results show that: (a) two types of CTIDs (CTID #1 and CTID #2) were identified that traveled radially from Tonga at the speed of 610–880 m/s (acoustic‐mode) and 300–380 m/s (Lamb‐mode), respectively.

Volcanology of the Raventhorpe and Pokeno West Volcanic Complexes, South Auckland Volcanic Field [PDF]

, 2012
The South Auckland volcanic field hosts at least 82 volcanic centres throughout the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The monogenetic basaltic volcanic field was active between 1.59 to 0.51 Ma, producing tuff rings, maar craters ...
