Assessing future reactive nitrogen inputs into global croplands based on the shared socioeconomic pathways
Only under the most optimistic sustainability scenario, the global synthetic fertilizer use in croplands stabilizes or even shrinks in the coming decades. In the most pessimistic fragmentation…
Uncertain Environmental Footprint of Current and Future Battery Electric Vehicles
The future environmental impacts of battery electric vehicles (EVs) are very important given their expected dominance in future transport systems. Previous studies have shown these impacts to be…
Large uncertainty in carbon uptake potential of land‐based climate‐change mitigation efforts
Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2°C or less. However, the carbon uptake potential in land‐based climate…
Scenarios for Demand Growth of Metals in Electricity Generation Technologies, Cars, and Electronic Appliances
This study provides scenarios toward 2050 for the demand of five metals in electricity production, cars, and electronic appliances. The metals considered are copper, tantalum, neodymium, cobalt, and…
Accurate assessment of anthropogenic carbon dioxide (CO 2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the global carbon budget – is important to better…
Scenarios towards limiting global mean temperature increase below 1.5 °C
The 2015 Paris Agreement calls for countries to pursue efforts to limit global-mean temperature rise to 1.5 °C. The transition pathways that can meet such a target have not, however, been extensively…
Biogeophysical Impacts of Land‐Use Change on Climate Extremes in Low‐Emission Scenarios: Results From HAPPI‐Land
The impacts of land use have been shown to have considerable influence on regional climate. With the recent international commitment to limit global warming to well below 2°C, emission reductions need…
Limited emission reductions from fuel subsidy removal except in energy-exporting regions
Hopes are high that removing fossil fuel subsidies could help to mitigate climate change by discouraging inefficient energy consumption and levelling the playing field for renewable energy. In…
Signal detection in global mean temperatures after Paris: an uncertainty and sensitivity analysis
Since large financial flows will be needed to keep GMSTs (global mean surface temperatures) below 2.0 °C, it is important to know how GMST has progressed since pre-industrial times. We performed an…
National contributions to climate change mitigation from agriculture: allocating a global target
Globally, agriculture and related land use change contributed about 17% of the world’s anthropogenic GHG emissions in 2010 (8.4 GtCO 2e yr −1), making GHG mitigation in the agriculture sector critical…
