With climate extremes' rising frequency and intensity, robust analytical tools are crucial to predict their impacts on terrestrial ecosystems. Machine learning techniques show promise but require well-structured, high-quality, and curated analysis-ready datasets. Earth observation datasets comprehensively monitor ecosystem dynamics and responses to climatic extremes, yet the data complexity can challenge the effectiveness of machine learning models. Despite recent progress in deep learning to ecosystem monitoring, there is a need for datasets specifically designed to analyse compound heatwave and drought extreme impact. Here, we introduce the DeepExtremeCubes database, tailored to map around these extremes, focusing on persistent natural vegetation. It comprises over 40,000 globally sampled small data cubes (i.e. minicubes), with a spatial coverage of 2.5 by 2.5 km. Each minicube includes (i) Sentinel-2 L2A images, (ii) ERA5-Land variables and generated extreme event cube covering 2016 to 2022, and (iii) ancillary land cover and topography maps. The paper aims to (1) streamline data accessibility, structuring, pre-processing, and enhance scientific reproducibility, and (2) facilitate biosphere dynamics forecasting in response to compound extremes.

Future climate extremes are expected to worsen existing inequalities in human exposure, yet the specific disparities across income groups are not well understood. We investigate how future floods, heatwaves, droughts, and compound hot-dry events will impact high- and low-income countries under various shared socioeconomic pathways (SSPs). We find that low-income countries are projected to experience more severe exposure to these events, primarily due to accelerated population growth rather than climate change.

Across the United States, power grids are increasingly under strain from extreme weather events, such as heatwaves, high winds, and heavy precipitation, that result in frequent, long-duration and widespread power outages. The strain is intensified when these events are compounded, which amplifies their impact and exacerbates the risk of disruptions. To identify weather variables driving outages and cluster regions based on these variables, we employed a self-organizing map (SOM) approach using county-level outage data from 2015 to 2022, obtained using the U.

Background: The climate crisis is increasingly recognised as a health crisis, driven in part by the growing frequency and intensity of climate-related hazards, such as heatwaves and wildfires. These hazards can coincide, potentially leading to compound impacts. However, little is known about where and how often such combinations occur globally.

Anthropogenic climate change is driving summer heat toward more humid conditions, accompanied by more frequent day-night compound heat extremes (high temperatures during both day and night). As the fast-warming and aging continent, Europe faces escalating heat-related health risks. Here, we projected future heat-related mortality in Europe using a distributed lag nonlinear model that incorporates humid heat and compound heat extremes, strengthened by a health risk-based definition of extreme heat and a scenario matrix integrating time-varying adaptation trajectories.

Background: The increasing frequency of compound drought and heatwave events (CDHWs) under global climate change has heightened the risk of forest pest outbreaks; however, precise quantitative assessments remain scarce. This study analyzed city-level forest pest incidence in China from 2003 to 2018 and utilized multiple machine learning models to quantify the impacts of droughts, heatwaves, and CDHWs on forest pest dynamics.
Results: The findings reveal that forest pest incidence exhibits a clear spatial pattern in China, with higher rates in the east and lower rates in the west, distinctly separated by the Hu Line.
