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…
Exploring SSP land-use dynamics using the IMAGE model: Regional and gridded scenarios of land-use change and land-based climate change mitigation
Projected increases in population, income and consumption rates are expected to lead to rising pressure on the land system. Ambitions to limit global warming to 2 °C or even 1.5 °C could also lead to…
Unpacking the nexus: Different spatial scales for water, food and energy
Recent years have shown increased awareness that the use of the basic resources water, food, and energy are highly interconnected (referred to as a ‘nexus’). Spatial scales are an important but…
Renewable energy generation and energy saving are increasing, energy consumption and greenhouse gas emissions are decreasing. However, various targets for energy and climate for 2020, will not be…
Trends in global CO2 and total greenhouse gas emissions: 2017 report
CO 2 emissions and total global greenhouse gas emissions are reported for 2016. Total global greenhouse gas emissions continued to increase by about 0.5% in 2016, reaching 49.3 gigatonnes in CO 2…
Open discussion of negative emissions is urgently needed
At the moment, nearly all model-based scenarios that limit global warming to 2 °C or less use negative CO 2 emission technologies (NETs), particularly bio-energy with carbon capture and storage (BECCS…
The worldwide context of China’s Green Transition to 2050
China is entering a crucial period of economic transformation, largely triggered by environmental issues. Chinese advisors are formulating a policy framework to guide this vast, complex and decades…
Integrated assessment of international climate mitigation commitments outside the UNFCCC
In the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC), for the first time, non-state actors were addressed in the international negotiations and were…
Greenhouse gas emission curves for advanced biofuel supply chains
Most climate change mitigation scenarios that are consistent with the 1.5–2 °C target rely on a large-scale contribution from biomass, including advanced (second-generation) biofuels. However, land…
