A century of variability of heatwave-driven streamflow in melt-driven basins and implications under climate change

Environmental Research Letters
Meltwater runoff from snow and glaciers in high mountain regions supports the water needs of hundreds of millions of people, but extreme events such as heatwaves modify the timing and magnitude of water available for downstream communities and ecosystems.

Air-for-water substitution in characterizing lake heatwaves in the middle and lower reaches of the Yangtze River Basin

Journal of Hydrology: Regional Studies
Study region: This study focuses on seventeen lakes with surface area larger than 100 km2 located in the middle and lower reaches of the Yangtze River Basin, China. Study focus: This study compares the spatiotemporal differences between lake heatwave and

Large Proportions of Surface Ozone and Premature Mortality Due to a Stratospheric Intrusion Event in North China

International Journal of Climatology, EarlyView.
This study, by examining a typical stratospheric intrusion event that occurred in North China from 30 to 31 July 2021, found that the event led to a sharp increase in near‐surface ozone concentrations by 23 ppbv within 36 h, accounting for 40% of the total observed ozone levels, with localised peaks exceeding 30 ppbv.

Projected Intensification of Hydroclimatic Extremes in Rio Grande do Norte, Brazil, Under CMIP6 Scenarios

International Journal of Climatology, EarlyView.
The graphical abstract presents observed (1963–2023) and projected changes in hydroclimatic extremes in Rio Grande do Norte, Brazil. It integrates dry‐spell duration (CDD) and extreme precipitation (R95pTOT) using CMIP6 multimodel ensembles under SSP1‐2.6, SSP2‐4.5, and SSP5‐8.5.

Manifold increase in the spatial extent of heatwaves in the terrestrial Arctic

Communications Earth & Environment
It is widely acknowledged that the intensity, frequency and duration of heatwaves are increasing worldwide, including the Arctic. However, less attention has been paid to the land area affected by heatwaves.

Seafloor marine heatwaves outpace surface events in the future on the northwestern European shelf [PDF]

Ocean Science
Marine heatwaves are becoming increasingly frequent across the world's oceans. As a result, there are growing impacts on marine ecosystems due to temperatures exceeding the thermal niche and historical exposure of many species.

Applicability of the steady‐state oxygen stable isotope method for estimating metabolism in low‐productivity Arctic lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Metabolism is a key property of lake ecosystem functioning, but logistical challenges make it difficult to estimate across remote regions. The steady‐state dissolved oxygen (DO) stable isotope method (18O method) estimates metabolism from discrete water samples and thus enables large‐scale surveys.

The effects of single versus successive warm summers on an intertidal community

Oikos, EarlyView.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.
