TLDR
In this paper, the authors used 100 environmental time series, 31 climatic and 69 biological, to determine if there is evidence for common regime signals in the 1965-1997 period of record.About:

Warming Patterns Affect El Nino Diversity in CMIP5 and CMIP6 Models
TL;DR: In this paper, the frequency and intensity of El Nino events are assessed in models from phases 5 and 6 of the Coupled Model Intercomparison Project (CMIP5 and CMIP6), and results are compared to extended instrumental and multicentury paleoclimate records.

Changing habitat and habitat use by birds after the exxon valdez oil spill, 1989–2001
TL;DR: In this paper, the effects of the Exxon Valdez oil spill on habitat use and occupancy during midsummer by marine-oriented birds over a 12-yr period following the spill in 1989, were surveyed in 10 study bays in Prince William Sound, Alaska, USA.

Is there evidence for a shift in fish growth and recruitment success linked to climate change
TL;DR: The north wall (northern boundary) of the Gulf Stream has been undergoing a displacement south since the late 1990s, and the speed and amplitude of the change appears to support the hypothesis that there was a regime shift in the climate of the North Atlantic Ocean.

Otolith biochronology as an indicator of marine fish responses to hydroclimatic conditions and ecosystem regime shifts
Szymon Smoliński,Zuzanna Mirny +1 more
TL;DR: Information is reported concerning the response of the commercially important European flounder to the changing environment that may support future ecosystem-based management of fish stocks and highlight the potential for applying biochronological techniques to identify rapid regime shifts in marine ecosystems.

Increased surface seawater pCO2 in the eastern Bering Sea shelf: An effect of blooms of coccolithophorid Emiliania huxleyi?
TL;DR: In this paper, a principal component analysis demonstrated that there are two spatial scales of pCO2 variability associated with E. huxleyi blooms: a small-scale variation (∼0.2° in latitude), which shows a decrease of p CO2 by 18 μatm relative to surrounding waters.

A Pacific interdecadal climate oscillation with impacts on salmon production
TL;DR: In this article, the authors identify a robust, recurring pattern of ocean-atmosphere climate variability centered over the midlatitude North Pacific basin over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal timescales.

The Arctic oscillation signature in the wintertime geopotential height and temperature fields
TL;DR: The Arctic Oscillation (AO) as mentioned in this paper is the signature of modulations in the strength of the polar vortex aloft, and it resembles the NAO in many respects; but its primary center of action covers more of the Arctic, giving it a more zonally symmetric appearance.

Teleconnections in the Geopotential Height Field during the Northern Hemisphere Winter
John M. Wallace,David S. Gutzler +1 more
TL;DR: In this paper, a review of existing literature on the subject reveals the existence of at least four such patterns: the North Atlantic and North Pacific Oscillations identified by Walker and Bliss (1932), a zonally symmetric seesaw between sea level pressures in polar and temperature latitudes, first noted by Lorenz (1951), and what we will refer to as the Pacific/North American pattern, which has been known to operational long-range forecasters in this country since the 1950's.

Classification, seasonality and persistence of low-frequency atmospheric circulation patterns
TL;DR: In this article, Orthogonally rotated principle component analysis (RPCA) was used to identify and describe the seasonality and persistence of the major modes of interannual variability.
