Introduction Understanding where greenhouse gas emissions originate helps identify where mitigation efforts can have the greatest impact. While emissions come from a range of activities, certain sectors consistently account for larger shares of the total global footprint. This article explores the major sources of greenhouse gases, the relative importance of each sector, and how trends […]

Introduction Climate change is reshaping the living calendar of the natural world. Across continents, shifts in temperature, precipitation, and extreme weather are altering when species emerge, migrate, breed, and form communities. Phenology—the study of these timing changes—offers a window into how organisms respond to rapidly changing climates, revealing patterns that cross biomes from tropical forests

Introduction Global climate change is reshaping the timing of life history events in the natural world. Across continents, shifts in temperature, precipitation, and seasonal cues are cascading through ecosystems, altering when plants flower and fruit, when insects emerge, and when birds migrate and breed. These phenological changes do not occur in isolation; they interact with

Introduction Climate change reshapes the rhythms of life on Earth by shifting when species unfold their key life cycle events. Across continents, changes in temperature, precipitation, and seasonal cues alter the timing of flowering, breeding, migration, hibernation, and metamorphosis. The resulting phenological shifts ripple through ecosystems, modifying interactions among plants, pollinators, herbivores, and predators, and

Climate change is reshaping the timing of natural events in species around the world. From the budding of leaves to the migratory spurts of birds and the flowering schedules of plants, phenology—the study of these seasonal life-cycle events—serves as a sensitive indicator of ecological response to shifting climates. Across continents, continents, and biomes, phenological changes

Cover crops have emerged as a central component of sustainable agriculture, offering a suite of benefits that extend far beyond short-term weed suppression or soil protection. By linking living plant cover to the soil’s biological, chemical, and physical processes, cover crops help build soil health, increase carbon storage, and foster resilient agroecosystems. This article synthesizes

Introduction Measuring soil carbon sequestration in the field is essential for understanding the effectiveness of land management practices, validating climate-smart agriculture programs, and informing policy and carbon markets. This article presents a comprehensive overview of practical, field-ready methods for quantifying soil organic carbon (SOC) stocks and changes over time. Emphasis is placed on techniques that

Introduction Soil organic carbon (SOC) stocks play a pivotal role in regulating the global carbon cycle, supporting soil health, and mitigating climate change. In the past few years, a growing body of high-resolution measurements, global syntheses, and predictive maps has refined understanding of how SOC varies across biomes, land uses, and depths, and how climate,

Introduction Geomorphology—the science of landforms and the processes that sculpt them—plays a central, though often understated, role in shaping soil carbon dynamics. The arrangement of hills and valleys, slopes and plains, and the distribution of sediments created by rivers, glaciers, winds, and tectonics create a mosaic of microclimates, soil types, hydrology, organic matter inputs, and

What is soil science’s main focus within geodiversity research? This article dives into how soil science contributes to understanding the broader concept of geodiversity, the variety of soils as a fundamental component of the Earth’s biodiversity and landscapes. By examining soil-forming processes, spatial distribution, and temporal dynamics, soil science illuminates how soils shape and are
