Global Change Biology is a peer-reviewed scientific journal and field of study addressing biological responses to large-scale environmental change. It synthesizes research from terrestrial, freshwater, and marine systems to understand how shifts in climate, land use, biogeochemical cycles, and socio-political drivers reshape species, communities, and ecosystem processes. Scholars publishing in the field draw on traditions from ecology, physiology, evolutionary biology, and Earth system science to inform policy debates associated with international processes.

Overview and Scope

Global change biology integrates observational, experimental, and modeling work spanning institutions such as IPCC, United Nations Environment Programme, National Aeronautics and Space Administration, European Space Agency, Smithsonian Institution, Scripps Institution of Oceanography, Woods Hole Oceanographic Institution, Max Planck Society, Commonwealth Scientific and Industrial Research Organisation, US Geological Survey, University of Cambridge, University of Oxford, Stanford University, Harvard University, Yale University, University of California, Berkeley, University of British Columbia, Australian National University, Peking University, Tsinghua University, Indian Institute of Science, ETH Zurich, University of Tokyo, Princeton University, Columbia University, Imperial College London, University of Copenhagen, Leiden University, University of Melbourne, University of Minnesota, University of São Paulo, University of Cape Town, King's College London, California Institute of Technology, Massachusetts Institute of Technology, University of British Columbia, Duke University, Ohio State University, Cornell University, University of Michigan, McGill University, University of Alberta, Utrecht University, Leipzig University, University of Helsinki, Lund University, Stockholm University, Université Paris Saclay, CNRS, Max Planck Institute for Biogeochemistry, International Union for Conservation of Nature to address cross-scale questions. Research covers organismal responses, community reassembly, biogeochemical feedbacks, and socio-ecological interactions relevant to multinational agreements such as the Paris Agreement and frameworks like the Convention on Biological Diversity.

Drivers of Global Change

Primary drivers examined include rising atmospheric carbon dioxide, changing concentrations of methane, nitrous oxide, and aerosols linked to industrialization and events such as the Industrial Revolution. Land-use change driven by expansion associated with entities like European Union agricultural policy, BRICS development, and frontier deforestation in regions like the Amazon Rainforest and Congo Basin alters habitat structure and connectivity. Anthropogenic climate trends recorded by networks including HadCRUT intersect with ocean acidification driven by CO2 uptake studied by programs like Global Ocean Observing System. Biological invasions associated with globalization, illustrated by pathways such as shipping through the Panama Canal or trade hubs like Port of Shanghai, and pollution episodes exemplified by incidents near Chernobyl and urban centers like Beijing compound change. Additionally, geopolitical events—wars including the Gulf War and sanctions affecting resource extraction—can modulate emissions and land management.

Impacts on Ecosystems and Biodiversity

Global change biology documents shifts in species distributions observed along gradients from the Alps to the Great Barrier Reef, community turnover in ecoregions such as the Mediterranean Basin and Boreal Forests, and phenological mismatches evident in systems studied at sites like Hubbard Brook Experimental Forest and Wytham Woods. Population declines paralleling cases like the Passenger Pigeon extinction inform extinction risk assessments used by the IUCN Red List and national conservation agencies. Trophic cascades following apex predator changes reminiscent of reintroductions such as Yellowstone National Park wolves demonstrate indirect effects, while coextinction risks are informed by mutualisms exemplified by pollination networks involving species in the Cape Floristic Region and California Floristic Province. Disease dynamics influenced by warming and land-use change mirror patterns noted in outbreaks documented by institutions including Centers for Disease Control and Prevention and World Health Organization.

Impacts on Ecosystem Functioning and Services

Shifts in primary productivity measured in biomes from the Amazon Rainforest to the Siberian tundra alter carbon budgets central to models developed by groups like the Coupled Model Intercomparison Project. Changes in decomposition and soil carbon cycling, studied at sites such as Long-Term Ecological Research stations, influence atmospheric composition and feedbacks to climate phenomena such as the El Niño–Southern Oscillation. Fisheries productivity shifts in regions like the North Sea and Gulf of Mexico impact provisioning services and economies tied to ports such as New Bedford, Massachusetts and Plymouth, England. Water regulation services mediated by wetlands in the Everglades and Okavango Delta are affected by hydrological changes from dams like Three Gorges Dam and irrigation schemes championed by agencies such as Food and Agriculture Organization. Cultural services linked to landscapes like the Alhambra and Mount Kilimanjaro face alteration, affecting tourism industries connected to operators such as national parks and UNESCO World Heritage listings.

Methods and Approaches in Global Change Biology

Methodological pluralism defines the field: remote sensing from satellites launched by Landsat, Sentinel, and MODIS; in situ experiments inspired by designs used at Manipulative Field Experiment sites; trait-based approaches drawing on datasets akin to TRY database; genomic tools applied in studies from laboratories at Broad Institute and Joint Genome Institute; and Earth system modeling coordinated through intercomparison efforts like CMIP. Statistical frameworks incorporate Bayesian techniques promoted at conferences like the Society for Industrial and Applied Mathematics meetings and machine learning methods implemented with tools originating at institutions such as Google and Microsoft Research. Citizen science platforms modeled after projects like eBird and iNaturalist augment observational coverage, while long-term monitoring networks exemplified by LTER Network and NEON provide baseline data.

Mitigation, Adaptation, and Management Strategies

Response strategies span mitigation—carbon sequestration initiatives inspired by afforestation projects in the Loess Plateau and blue carbon programs in the Mangroves of Sundarbans—and adaptation measures such as assisted migration trials paralleling work in Scotland and managed realignment in places like the Somme Bay. Policy instruments from mechanisms under the United Nations Framework Convention on Climate Change to national legislation shape land-management, while market mechanisms like carbon markets and conservation finance operate through exchanges influenced by firms based in London and New York City. Restoration ecology efforts informed by practitioners at organizations such as The Nature Conservancy and Conservation International implement practices including rewilding showcased in projects at Pleistocene Park and community-based management approaches seen in indigenous territories across the Amazon Basin and Great Plains.
