The Emissions Gap Report: Are the Copenhagen Accord Pledges Sufficient to Limit Global Warming to 2 °C or 1.5 °C?
It is estimated that, in order to have a likely chance (over 66%) of limiting global mean temperature increase to 2 °C, annual greenhouse gas emissions need to stay around 44 gigatonnes, by 2020. If…
Assessing 20th century climate–vegetation feedbacks of land-use change and natural vegetation dynamics
This study describes the coupling of the dynamic global vegetation model (DGVM), Lund–Potsdam–Jena Model for managed land (LPJmL), with the general circulation model (GCM), Simplified…
A quantitative minimax regret approach to climate change: Does discounting still matter?
Integrated assessment models have been widely used to inform policymakers about attractive climate response strategies. An important application of integrated assessment models is cost-benefit…
Policy research programme on particulate matter. Main results and policy consequences
Recent research has clarified a number of facts about particulate matter in the atmosphere and has overturned a number of assumptions. For example, it is now clear that a much greater proportion of…
Acid rain. An analysis of thirty years of Dutch acidification policy
In the past, no unnecessary policy measures have been taken to reduce acidification (acid rain). Although the severity of acidification has declined because of policy implementation, acidification…
How to deal with indirect land-use change in the EU Renewable Energy Directive?
Biofuels based on agricultural crops have the risk of causing indirect land use change with substantial greenhouse gas emissions. European policy to stimulate innovative solutions without these…
Mineral dust is a constituent of atmospheric particulate matter (PM 10 ). It originates from diverse sources, such as wind erosion, agricultural land management and resuspension by road transport…
What do near-term observations tell us about long-term developments in greenhouse gas emissions
Long-term scenarios developed by integrated assessment models are used in climate research to provide an indication of plausible long-term emissions of greenhouse gases and other radiatively active…
Research priorities in land use and land-cover change for the Earth system and integrated assessment modelling
This special issue has highlighted recent and innovative methods and results that integrate observations and modelling analyses of regional to global aspect of biophysical and biogeochemical…
