Here, Miller et al. investigate trends of occupancy for 81 species of amphibians across North America and find greater sensitivity to water availability during breeding and winter conditions than mean climate.

Deep stratospheric ozone intrusions can elevate western US ground-level ozone to unhealthy concentrations, but the factors driving interannual variability are poorly understood. Here, the authors combine observations and numerical simulations showing a link between intrusion events and strong La Niña winters.

The temperature-sensitivity of soil dissolved organic carbon (DOC) export is widely debated but limited by the duration of observations. New data from environmental archives supports a pronounced sensitivity between soil DOC leaching and warming.

Liu et al. investigate the ‘boiling frog’ effect and demonstrate that binary climate data visuals increase climate change perception via creating an ‘illusion’ of sudden shifts.

This study presents hourly data from a thermistor string in Lake Michigan, inspecting its response at depth to surface warming. Based on the data, the study suggests bottom lake temperatures respond to changes in turnover and re-stratification, with the ultimate possibility of the lake shifting from dimictic to monomictic.

Literature analysis and numerical modeling experiments suggest the continentality of a permafrost region determines whether the ground experiences warming or cooling as a consequence of heavy summer rainfall.

Crop models suggest that early sowing and slower-developing cultivars could maintain Australian wheat yields despite less-favourable climatic conditions. Field trials now confirm the potential of this adaptation for wheat production across Australia.

Baleen whales migrate from high latitude feeding grounds to subtropical reproductive winter grounds, translocating limiting nutrients across ecosystems. This study estimates the latitudinal movement of nutrients from carcasses, placentas and urea for four species of baleen whales that exhibit annual migrations.

Zymoseptoria tritici is an important fungal pathogen of wheat which has spread globally. Here, the authors perform genomic analyses on a collection of ~1100 Z. tritici samples from 42 countries to describe its global spread and elucidate mechanisms of adaptation to different environmental conditions.

Regional differences in SARS-CoV-2 variants may affect treatment outcome. Here, the authors show that near-sourced convalescent plasma has higher efficacy, as defined by death within 30 days of transfusion, than plasma sourced more than 150 miles away.

Data on the richness and composition of the skin microbiome from 2,349 individual amphibians, representing 205 species across a broad geographic range, is compared with local biotic and abiotic environmental factors.

In the summer, low-income households in the Arizona, US wait 4 - 7 °F (2.6–4.2 °C) longer than high-income households to turn on their AC units to save money on energy bills. This energy limiting behavior indicates a hidden form of energy poverty.

Thawing permafrost releases carbon that serves as a positive feedback on climate warming. Here the authors experimentally demonstrate that rainfall extremes in the Siberian tundra increase permafrost thaw for multiple years, especially if rainfall coincides with warm periods.

Mid-Holocene climate was characterized by strong summer solar heating that decreased Arctic sea ice cover. Here the authors show that this sea ice loss had profound effects on the climate system, distinct from direct effects of solar heating, over North America, northern Asia, and the North Atlantic.

Environmental variation has been hypothesized to favour the evolution of large brains capable of adjusting behaviour to changing circumstances. Here, Sayolet al. find that across more than 1200 bird species, species with relatively large brains are indeed associated with more variable habitats.

The endogenous opioid system regulates fear and anxiety, but the underlying cellular mechanism is unclear. Winterset al. shows that in the intercalated cells (ITC) of the amygdala, endogenous opioids suppress glutamatergic inputs via the δ-opioid receptor presynaptically, and reduce the excitability of ITCs via the μ-opioid receptor postsynaptically.

The dynamic components of coastal water level can add metres to water levels during extreme events. A data synthesis reveals that Pacific regional wave and water level fluctuations are closely related to the El Niño/Southern Oscillation.

Will networks of protected areas remain effective as the climate changes? Research into the response of bird populations to climate variance and change attempts to shed light on this issue. Results suggest that despite projected declines in many of the species investigated, most sites that are designated as EU Special Protection Areas in the UK can be expected to retain their conservation value and legal status.

Persistent millennial Asian winter monsoon variability is shown to be superposed on orbital 41-kyr and 100-kyr cycles across the Pliocene–Pleistocene glacial intensification using a paleomagnetically dated high-resolution Chinese Loess Plateau grain size record.

Integrating inventory data with machine learning models reveals the global composition of tree types—needle-leaved evergreen individuals dominate, followed by broadleaved evergreen and deciduous trees—and climate change risks.

Proto-monsoon expansion doubled rainfall in Central Asia during an early Eocene hyperthermal, leading to a rapid if transient expansion of forests replacing the steppe-desert.

Data from 143 weather radars provide an estimate of biomass flows from nocturnal migrating birds across the continental United States, providing a picture of survival rates for species with different life-history and migratory strategies.

Accurate seasonal forecasts of sea ice are highly valuable, particularly in the context of sea ice loss due to global warming. A new machine learning tool for sea ice forecasting offers a substantial increase in accuracy over current physics-based dynamical model predictions.

Global warming drove ‘wet gets wetter and dry gets drier’ climate shifts in Asia ~5.3 million years ago with monsoon pacing by ~400,000 and ~ 100,000 year cycles. This could be a template for future Asian climate response to anthropogenic warming.

Oceanic motions associated with horizontal scales smaller than 50 km remain unresolved in climate models. Here the authors show that motions in this scale range are critical to the global transport of heat between the ocean interior and the atmosphere, and are thus a key component of the Earth’s climate.

Patients with chronic lung disease (CLD) have an increased risk for severe coronavirus disease-19 and poor outcomes. Here the authors compare the transcriptomes of single cells isolated from healthy and CLD lungs to identify molecular characteristics of lung cells that may account for worse COVID-19 outcomes in these patients.

Infectious and chronic diseases display seasonal patterns, yet seasonal changes in physiology are rarely thought to affect human health. Here the authors show seasonal variation in all major blood cells and in gene and protein expression in diverse tissues, suggesting a mechanism for seasonal disease proneness and physiology.

Marine records indicate a greenhouse to icehouse climate transition at ~34 million years ago, but how the climate changed within continental interiors at this time is less well known. Here, the authors show an orbital climate response shift with aridification on the northeastern Tibetan Plateau during this time.

A pan-betacoronavirus vaccine will likely require the elicitation of antibodies against spike regions conserved across diverse coronaviruses. Here, authors computationally engineer and experimentally validate immunogens to elicit antibodies against two such spike regions.

Influenza can occasionally result in life-threatening sequelae. Openshaw and colleagues describe the functional and transcriptional response to natural infection with influenza virus and find that a transition to an ‘anti-bacterial response’ is associated with more-severe symptoms.

Abrupt changes are developing across Antarctica’s ice, ocean and biological systems; some of these changes are intensifying faster than equivalent Arctic changes, potentially irreversibly, and their interactions are expected to worsen other impacts across the Antarctic environment and global climate system.

Comprehensive integration of gene expression with epigenetic features is needed to understand the transition of kidney cells from health to injury. Here, the authors integrate dual single nucleus RNA expression and chromatin accessibility, DNA methylation, and histone modifications to decipher the chromatin landscape of the kidney in reference and adaptive injury cell states, identifying a transcription factor network of ELF3, KLF6, and KLF10 which regulates adaptive repair and maladaptive failed repair.
