Climate dissonance
To meet the goals of the Paris Agreement and limit anthropogenic global warming to 1.5 °C (or below 2 °C), research indicates that a substantial proportion of the world's remaining fossil fuel reserves must remain unextracted. Despite this, several fossil-producing countries continue to expand hydrocarbon activity. Norway represents a particularly important case because it combines high levels of climate concern with continued support for oil and…
Freshwater biodiversity in a rapidly changing Arctic
Arctic freshwater biodiversity is rapidly changing due to climate warming, resource extraction, infrastructure development, and landscape transformation. To improve understanding, predict future responses, and inform policy formulation, research needs must be clearly identified. Using a horizon scan survey, Arctic freshwater experts from government, international agencies, and Indigenous Peoples identified 77 biodiversity research questions with …
Governance for Earth system tipping points – A research agenda
Tipping points in the Earth system could be passed within the Paris Agreement's temperature goal range (1.5°C–2°C). Tipping processes are a feature of complex Earth system dynamics that present major governance challenges not addressed by existing global governance institutions. The common governance toolkit is a poor match for dealing with tipping processes, especially non-linear change, and radical intertemporality. To support the development o…
Biotic Deterioration and Homogenization
Globally, locally, and regionally, there are different patterns of biotic diversity and community composition reflecting past evolutionary history shaped by differences in niches, productivity, climate, and other ambient factors, as well as migration barriers. Historically, humans have impacted and eroded these biotic patterns, notably by the impact of agriculture in a wide sense, but to an increasing extent also by logging, overharvesting, sprea…
Buffering Climate Change with Nature
It is increasingly evident that climate sustainability depends not only on societal actions and responses, but also on ecosystem functioning and responses. The capacity of global ecosystems to provide services such as sequestering carbon and regulating hydrology is being strongly reduced both by climate change itself and by unprecedented rates of ecosystem degradation. These services rely on functional aspects of ecosystems that are causally link…

Global change and ecosystem connectivity
Migratory connectivity by birds may mutually affect different ecosystems over large distances. Populations of geese overwintering in southern areas while breeding in high-latitude ecosystems have increased strongly over the past decades. The increase is likely due to positive feedbacks caused by climate change at both wintering, stopover sites and breeding grounds, land-use practices at the overwintering grounds and protection from hunting. Here …
Blueprint for the Global Village
Life consists of units within units. In the biological world, we have genes, individuals, groups, species, and ecosystems-all nested within the biosphere. In the human world, we have genes, individuals, families, villages and cities, provinces, and nations-all nested within the global village. In both worlds, a problem lurks at every rung of the ladder: a potential conflict between the interests of the lower-level units and the welfare of the hig…
