Enhanced North American carbon uptake associated with El Niño

Science Advances, 2019
North American ecosystems absorb more CO2 from the atmosphere during El Niño than during La Niña periods. Long-term atmospheric CO2 mole fraction and δ13CO2 observations over North America document persistent responses to the El Niño–Southern Oscillation.

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

River Research and Applications, EarlyView.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Coupling of El Niño events and long-term warming leads to pervasive climate extremes in the terrestrial tropics

Environmental Research Letters, 2019
The El Niño Southern Oscillation (ENSO) is a major driver of seasonal and interannual climatic variability across the tropics. The 2015/16 El Niño event was one of the strongest El Niño events of the past century.

Strip loading in reinforced concrete: Mechanical modeling and experimental validation

Structural Concrete, EarlyView.
Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

Heat stress in tropical highland regions: the case of Kenya during February 2024

Weather, EarlyView.
Understanding and awareness about heat stress remain low in sub‐Saharan countries despite high exposure and vulnerability. After the national media in Kenya reported that people had complained about unusual heat stress during February 2024, we combine in situ and reanalysis data to (i) put this event into climatological perspective, and (ii) give ...

Record‐breaking May heat in the UK: contrasting the extreme temperatures of 2024 and 1944 using climate attribution

Weather, EarlyView.
This study quantifies the likelihood of May temperature extremes in present, natural (climatology based on pre‐industrial forcings) and future climates. The attribution applies in the context of a May heatwave comparable to the record‐breaking 1944 event and the persistent record‐breaking monthly‐mean temperature from 2024.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Virility, fascism and regeneration in post‐Civil War Spain: On interpretations of literary Romanticism under the Franco regime

Gender &History, EarlyView.
Abstract In the years immediately following the Spanish Civil War, the political culture of Falangism developed a deeply gendered regenerationist discourse, which proposed that regeneration would only be possible if the nation recovered its virile attributes.
