  • Antarctica has a unique environment and geographic isolation that affect its biodiversity patterns. In this Perspective, the authors examine how five key ecological processes shape Antarctica’s biodiversity and use this information to establish predictions for future change in the region.

  • Global mean sea surface surface temperature shows decadal fluctuations superimposed to the warming trend whose causes are still debated. Here, the authors provide a quantification of relative contributions of different drivers and conclude that both internal and externally-forced variability play a comparable role.

  • Wildfires are becoming increasingly frequent in several regions around the world due to climate change, posing serious health risks, especially for respiratory diseases. This study examines the respiratory health risk and burden of wildfire-specific PM2.5 pollution across eight countries and territories.

  • The Southern Annular Mode (SAM) has shifted towards its positive phase owing to ozone depletion and increasing greenhouse gas concentrations. This Review discusses the dynamics, trends and projections of the SAM and how these will affect southern high-latitude climate, including Southern Ocean circulation, carbon cycling and the Antarctic cryosphere.

  • In some decades, such as 2000–2009, the observed globally averaged surface-temperature time series has shown a flat or slightly negative trend. A modelling study provides evidence that heat uptake by the deep ocean may cause these hiatus periods and may be linked to La Niña-like conditions.

  • Accounting for natural decadal variability allows better prediction of short-term trends. This study looks at the ability of individual models, which are in phase with the Interdecadal Pacific Oscillation, to simulate the current global warming slowdown. The authors highlight that the current trend could have been predicted in the 1990s with this technique and the need for consistent hindcast skills to allow reliable decadal predictions.

  • Evaluating the short-term exposure to wildfire-specific fine particulate matter (PM2.5) showed greater risks of hospitalization for all major respiratory diseases than non-wildfire PM2.5. When developing air quality guidelines, it is also important to consider that PM2.5 from varying sources can have different health effects, which require targeted health and environmental policy approaches.

  • In late 2016, there was a sudden and subsequently sustained decrease of Antarctic sea ice extent. Analyses of observations and a model simulation trace the causes to teleconnections from the tropics on the interannual timescale combined with decadal-timescale warming in the upper Southern Ocean.

  • Antarctic sea ice extent declined dramatically in austral spring 2016. This study shows the decline was initially driven by tropical convection resulting in a wave-3 circulation pattern, followed by weakened circumpolar surface westerlies initialised in the polar stratospheric vortex.

  • The Asian wet season in the Early Eocene was notably shorter and weaker compared to the present-day Asian summer monsoon, primarily attributed to the absence of the Tibetan highland as a heat source, according to DeepMIP-Eocene multi-model ensemble paleoclimate simulations.
