The Most Effective Remote Forcing in Causing U.S.‐Wide Heat Extremes as Revealed by CESM Green's Function Experiments

Geophysical Research Letters, 2023
We make use of the Community Atmosphere Model version 5 Green's function q‐flux perturbation experiments to explore the most effective remote forcing in driving U.S.‐wide summer heat extremes.

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Opposing contributions of the tropical Pacific to recent burned forest area trends in Eastern Australia and the Southwestern United States

Environmental Research Letters
The Southwestern U.S. and Eastern Australia are two of the most fire-prone regions of the world. These two regions also have significant and opposite-signed hydroclimate teleconnections to sea-surface temperature (SST) anomalies in the tropical Pacific ...

Connection between the Tropical Pacific and Indian Ocean and Temperature Anomaly across West Antarctic

npj Climate and Atmospheric Science, 2023
West Antarctic and the Antarctic Peninsula have experienced dramatic warming in austral spring since the 1970s. Using observations and the Community Atmosphere Model version 4 (CAM4), this study explores the physical mechanism by which the tropical ...

Spatially heterogenous range dynamics since the Last Glacial Maximum underpin the modern bimodal latitudinal diversity gradient in planktonic foraminifera

Ecography, EarlyView.
The modern latitudinal diversity gradient (LDG) of planktonic foraminifera is bimodal, with a distinct depression near the equator surrounded by mid‐latitude diversity peaks. This pattern emerged after the Last Glacial Maximum (LGM; 19–23 ka), but it remains unclear how species' spatial dynamics contributed to its formation.

On the Variability and Predictability of Eastern Pacific Tropical Cyclone Activity*

Journal of Climate, 2015
AbstractVariability in tropical cyclone activity in the eastern Pacific basin has been linked to a wide range of climate factors, yet the dominant factors driving this variability have yet to be identified. Using Poisson regressions and a track clustering method, the authors analyze and compare the climate influence on cyclone activity in this region ...

Oceanic upwelling and productivity in the eastern tropical Pacific [PDF]

Limnology and Oceanography, 1991
An oceanographic survey of the eastern tropical Pacific Ocean in August-November 1990 found a productive, nutrient-rich, moderately high-chlorophyll surface layer in two oceanic upwelling regions: the equatorial divergence, especially east of the Galapagos, and the countercurrent divergence out to 105”W, > 1,000 km west of the Costa Rica1 Dome ...

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Contrasting Heatwave Regimes in Dry and Humid Subtropical Mexico: A Station‐Based Probabilistic Assessment

International Journal of Climatology, EarlyView.
Heatwaves have intensified under a warming climate, producing substantial environmental and societal impacts. This study characterizes heatwave regimes in two contrasting regions of Mexico using a percentile‐based threshold and a Poisson distribution framework.
