Subjects: Environmental Studies, Geographic Information Sciences, Geography, Human Geography, Nature and Society Relations, Other Geography, Physical and Environmental Geography, Remote Sensing, Spatial Science

CORINE Land Cover is one of the most relevant Land Use Cover (LUC) databases in Europe because of its degree of detail and long time series. Although some studies have assessed the uncertainty of the database for specific years and periods, no work has been found that analyses all the available CORINE time series (1990-2018). In this study, we analyze the uncertainties of the CORINE time series [...]

Kaiyu Guan, Zhenong Jin, Evan H. DeLucia, et al.

Published: 2022-01-01
Subjects: Environmental Studies, Physical and Environmental Geography, Remote Sensing, Social and Behavioral Sciences

Agriculture contributes nearly a quarter of global greenhouse gas (GHG) emissions, which is motivating interest in certain farming practices that have the potential to reduce GHG emissions or sequester carbon in soil. The related GHG emission (including N2O and CH4) and changes in soil carbon stock are defined here as “agricultural carbon outcomes”. Accurate quantification of agricultural carbon [...]

Recent advances in citizen weather station (CWS) networks, with data accessible via crowd-sourcing, provide relevant climatic information to urban scientists and decision makers. In particular, CWS can provide long-term measurements of urban heat and valuable information on spatio-temporal heterogeneity related to horizontal heat advection. In this study, we make the first compilation of a [...]

Geographically-resolved social cost of anthropogenic emissions accounting for both direct and climate-mediated effects

Jennifer Burney, Geeta G Persad, Jonathan Proctor, et al.

Published: 2021-11-17
Subjects: Atmospheric Sciences, Climate, Environmental Sciences, Physical and Environmental Geography, Sustainability

The magnitude and distribution of physical and societal impacts from long-lived greenhouse gases are insensitive to the emission source location; the same is not true for major co-emitted short-lived pollutants like aerosols. Here we combine novel global climate model simulations with established response functions to show that identical aerosols emitted from different regions (Brazil, China, [...]

Climate change, fire return intervals and the growing risk of permanent forest loss in boreal Eurasia

Arden L Burrell, Qiaoqi Sun, Robert Baxter, et al.

Subjects: Climate, Environmental Indicators and Impact Assessment, Environmental Monitoring, Other Environmental Sciences, Physical and Environmental Geography, Remote Sensing, Spatial Science

Climate change has driven an increase in the frequency and severity of fires in Eurasian boreal forests. A growing number of field studies have linked the change in fire regime to post-fire recruitment failure and permanent forest loss. In this study we used four burnt area and two forest loss datasets to calculate the landscape-scale fire return interval (FRI) and associated risk of permanent [...]

This discrete change in coastline is different from most other climate change impacts, and offers a clear basis for scientifically-informed, [...]

Knowing the whole world from the top of a mountain: from orderly systematization to complex explanatory systems

Maarten G Kleinhans

Published: 2021-06-29
Subjects: Earth Sciences, Physical and Environmental Geography, Systems Biology

Fast and fascinating changes in views on nature and systems occurred around 1800, for example in the works of Alexander von Humboldt. While Humboldt rarely used the word system, he searched for the pattern-forming forces of nature by gruesome experiments on animals, including himself, and then drew a map of a mountain that became the basis of biogeography. What did ‘system’ mean then and now, how [...]

Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent of location. In reality, the success of hydrogen projects will be intimately linked to the availability of local energy resources, access to key infrastructure and water supplies, and the distance to export ports and energy markets. In [...]

The disaster trap: cyclones, tourism, colonial legacies, and the systemic feedbacks exacerbating disaster risk

Eli Lazarus

Subjects: Geography, Human Geography, Nature and Society Relations, Physical and Environmental Geography

The long, open-ended period of recovery from a disaster event is the phase of a disaster that the interdisciplinary field of disaster studies struggles to understand. In the process of rebuilding, places do not simply reset – they transform, often in ways that confound any reduction of disaster risk, instead making people and settings more vulnerable to future hazard events. Reducing disaster [...]
