Rising concentrations of atmospheric CO2 (ca) increase plant photosynthesis (An) and reduce stomatal conductance (gs). This increases the intrinsic water-use efficiency (iWUE = An / gs), a major proxy of tree adaptation to climate change. However, whether an increase in iWUE leads to a concomitant increase in tree growth remains in dispute, prompting interest in theoretical links between iWUE and tree productivity. Here using an optimality theory for kinetics of stomatal aperture, we establish an envelope delineating maximal relative increases in tree productivity that can be inferred/expected from relative increases in iWUE. The resulting expressions are used to interpret relations between iWUE (an observable proxy) and tree growth (the target variable), using available experimental data from manipulation experiments and tree-ring isotopes. While rising ca increases iWUE, proportional increases in tree growth are unlikely given ameliorating environmental (for example, rising atmospheric dryness) and anatomical/physiological (for example, tree height) influences. The authors theoretically delineate the maximal increases in tree growth that can be expected from increases in plant intrinsic water-use efficiency, which increases with rising CO2. They highlight environmental and physiological limits on growth in the context of experimental data.

Studies reporting shifts in species distributions may be biased by sampling choices, which can either exaggerate or underestimate range responses to various global changes. Here we demonstrate a geometric bias favouring sampling along latitude, which increases the likelihood of observing latitudinal range shifts as expected under climate warming. A global bias towards studying species redistributions preferentially along warming gradients may veil the true direction and magnitude of range shifts. The authors consider studies reporting species range shifts and demonstrate a geometric bias in sampling along latitudinal, rather than longitudinal, gradients. This bias may favour the corroboration of shift expectations with warming and mask other patterns and drivers of species movements.

The dynamics of carbon allocation in trees affect carbon storage of forest ecosystems and atmospheric carbon dioxide concentrations on Earth. Here, using carbon fluxes and xylem phenology from 84 conifer forests across the Northern Hemisphere, we quantify the phenology of carbon sources (photosynthesis) and sinks (stem growth) along a thermal gradient from −4.4 to 18.2 °C in mean annual temperature. The onset of stem growth advances by 2.3 days per degree Celsius with rising temperatures, 2 times slower than photosynthesis. Warmer sites accumulate less chilling than colder sites, thus trees require more heat to reactivate. The ending of photosynthesis and wood formation is delayed by 2.0 days per degree Celsius. Overall, the photosynthetic season lengthens by one month more than the growing season towards the warmest sites. Climate warming tends to intensify the mismatch between the phenology of carbon sources and sinks, potentially affecting the carbon sequestration in conifer forests. Measurements of carbon fluxes and wood phenology are used to assess carbon sources from photosynthesis and their sink into woody growth along a thermal gradient. The authors show that stem growth advances slower than photosynthesis per degree Celsius, creating a phenological mismatch for carbon.

Global warming is increasing the number and intensity of many extreme weather and climate events. Here we argue that extreme day-to-day temperature changes, exceeding the 90th percentile threshold of historical records, are an independent, but largely ignored, aspect of extreme weather events. Such extreme temperature changes have a stronger impact on human health in many locations than do diurnal temperature variations. Global observations show that such events have become more frequent since the 1960s in low and mid-latitudes but decreased at high latitudes, primarily due to GHG forcing. Climate models project a further amplification of extreme day-to-day temperature changes under warming, with frequency, amplitude and total intensity rising by ~17%, ~3% and ~20%, respectively, by 2100 in regions covering 80% of global population. Increased extreme day-to-day temperature changes are associated with drier soil and increased variability in pressure and soil moisture, posing substantial risks to societal and ecosystem resilience and adaptation. Climate change is expected to lead to higher day-to-day temperature variability in mid- to low latitudes. Here the authors show that extreme day-to-day temperature changes have distinct impacts on human health and become more frequent and intense in mid- to low latitudes with climate change.

Objective assessments indicate that extreme heat is increasing health risks; however, many of the most exposed populations do not perceive extreme heat as risky. This misperception may undermine public awareness of the need for effective cooling strategies, leaving a dangerous blind spot in adaptation and protection.

The potential death toll of exceptional extreme heat events is crucial for climate risk analysis and adaptation planning but may not be captured by existing projections. Here we combine machine learning-based projections of five historical European heat waves under present or future global temperatures with empirical exposure–response functions to quantify the potential for extreme heat events to generate mass mortality. For example, if August 2003 meteorological conditions recur at the recent annual global temperature anomaly of 1.5 °C, we project 17,800 excess deaths across Europe in one week, rising to 32,000 at 3 °C. This mortality is comparable to peak COVID-19 mortality in Europe and is not substantially reduced by climate adaptation currently observed across Europe. Our results suggest that while mitigating further global warming can reduce heat mortality, mass mortality events remain plausible at near-future temperatures despite current adaptations to heat. The authors couple calculations of historical heatwave intensity at present and future global temperatures with exposure–response functions to quantify mortality from extreme heat events in Europe. They project tens of thousands of excess deaths, with limited attenuation from existing adaptations.

Over recent decades, the Southern Ocean’s westerly winds have intensified and shifted poleward, whereas the Antarctic Circumpolar Current (ACC) transport through the Drake Passage has remained stable. Here using satellite altimetry data, we define the interannual evolution of the ACC’s dynamical boundaries and identify a significant southward shift of its Northern Boundary (NB) over the past three decades, with the most rapid migration (up to 1.1° per decade) occurring in the Southeast Pacific. Ocean reanalysis confirms that volume transport within the ACC’s boundaries remains stable across the circumpolar Southern Ocean, despite a strengthening eastward flow concentrated near the migrating NB. The migrating NB redirects this intensified flow into the subtropical gyre, strengthening the Southern Ocean supergyre while maintaining stable ACC transport. These results resolve the paradox of stronger zonal flows coexisting with stable ACC transport, providing insight into changing Southern Ocean dynamics and their climate implications. Climate change is altering the strength and position of Southern Ocean westerly winds but the ocean transport is stable. Here the authors use sea surface height to show that a poleward shift of the northern boundary and changing dynamics maintain the circumpolar transport.
