A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

open access: yesIbis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

Alaskan Ridge Blocking and Associated Winter Cold Conditions Over North America

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Multi‐decadal (1979–2023) analysis reveals that wintertime reductions in the meridional gradient of potential vorticity (PVy) over the Bering Sea are recurrent but episodic features of North Pacific circulation. These suppressed PVy states consistently co‐occur with amplified Alaskan ridging, weakened mid‐tropospheric westerlies and a downstream warm ...

Change in a Pacific Decadal Oscillation in observations

open access: yes, 2008
A long-term time series of the North Pacific mean sea surface temperature (SST) is characterized by two distinct epochs in observations, i.e., the cold epoch (1870-1935) versus the warm epoch (1945-2007).

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

An improvement of reproducibility of Pacific decadal oscillation in CMIP5

open access: yes, 2013
Pacific decadal oscillation (PDO) that is defined as the first mode of empirical orthogonal function of North Pacific sea surface temperature (SST) could affect variability of marine ecosystem as well as climate system in the North Pacific.

Weather Patterns Associated With Coastal Disasters in Santa Catarina, Southern Brazil

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
The study identified weather patterns (WPs) associated with coastal disasters between 1998 and 2020 along the Santa Catarina coast, Brazil. Using atmospheric and oceanographic data combined with official disaster records, five WPs were defined, mainly associated with cyclonic and anticyclonic systems linked to extreme wave events.

From archives to satellites: uncovering loss and resilience in the kelp forests of Haida Gwaii

open access: yesFrontiers in Marine Science
Coastal foundation species such as kelps, corals, and seagrasses play vital roles in supporting marine biodiversity and ecosystem services globally, but are increasingly threatened by climate change.

Relationship between growth rate and the Pacific Decadal Oscillation Index and growth rate and rainfall.

open access: yes, 2013
Relationships between A) growth rate and the Pacific Decadal Oscillation Index (PDO) between 1952 and 2008 and B) growth rate and rainfall between 1961 – 2008. Points are means ±1σ.
