Representative Concentration Pathway (RCP) 4.5 is a scenario that stabilizes radiative forcing at W m−2 in the year 2100 without ever exceeding value. Simulated with Global Change Assessment Model (GCAM), RCP4.5 includes long-term, global emissions of greenhouse gases, short-lived species, and land-use-land-cover economic framework. was updated from earlier GCAM scenarios to incorporate historical land cover information common RCP process follows cost-minimizing pathway reach target forcing....
Although the scale of impending urbanization is well-acknowledged, we have a limited understanding how urban forms will change and what their impact be on building energy use. Using both top-down bottom-up approaches scenarios, examine use for heating cooling. Globally, cooling by middle century between 45 59 exajoules per year (corresponding to an increase 7-40% since 2010). Most this variability due uncertainty in future densities rapidly growing cities Asia particularly China. Dense...
Abstract. This paper describes GCAM v5.1, an open source model that represents the linkages between energy, water, land, climate, and economic systems. is a market equilibrium model, global in scope, operates from 1990 to 2100 5-year time steps. It can be used examine, for example, how changes population, income, or technology cost might alter crop production, energy demand, water withdrawals, one region's demand affect land other regions. including its assumptions, inputs, outputs. We then...
Abstract Although the transition to renewable energies will intensify global competition for land, potential impacts driven by solar energy remain unexplored. In this work, land requirements and related use change emissions are computed EU, India, Japan South Korea. A novel method is developed within an integrated assessment model which links socioeconomic, energy, climate systems. At 25–80% penetration in electricity mix of those regions 2050, we find that may occupy 0.5–5% total land. The...
A rapid transition away from unabated coal use is essential to fulfilling the Paris climate goals. However, many countries are actively building and operating power plants. Here we plant-level data specify alternative trajectories for technologies in an integrated assessment model. We then quantify cost-effective retirement pathways global country-level fleets limit long-term temperature change. present our results using a decision-relevant metric: operational lifetime limit. Even if no new...
Stabilizing climate change well below 2 °C and towards 1.5 requires comprehensive mitigation of all greenhouse gases (GHG), including both CO2 non-CO2 GHG emissions. Here we incorporate the latest global emissions data into a state-of-the-art integrated assessment model GCAM examine 90 scenarios pairing different levels abatement pathways. We estimate that when contributions are not fully implemented, timing net-zero must occur about two decades earlier. Conversely, integrates measures in...
Increased ambition and implementation are essential.
Significance Devising sustainable climate change mitigation policies with attention to potential synergies and constraints within the climate–energy–water nexus is subject of ongoing integrated modeling efforts. This study employs a regional assessment model Earth system at high spatial temporal resolutions in Unites States compare implications two representative concentration pathways under consistent socioeconomics. The results clearly show, for first time our knowledge, that policies, if...
Abstract. Water scarcity conditions over the 21st century both globally and regionally are assessed in context of climate change mitigation policies, by estimating water availability demand within Global Change Assessment Model (GCAM), a leading community-integrated assessment model energy, agriculture, climate, water. To quantify changes future availability, new gridded water-balance global hydrologic – namely, Availability (GWAM) is developed evaluated. demands for six major sectors...
Abstract. Simple climate models play an integral role in the policy and scientific communities. They are used for mitigation scenarios within integrated assessment models, complex model emulation, uncertainty analyses. Here we describe Hector v1.0, open source, object-oriented, simple global carbon-cycle model. This runs essentially instantaneously while still representing most critical global-scale earth system processes. has a three-part main carbon cycle: one-pool atmosphere, land, ocean....
Abstract Future changes in climate and socioeconomic systems will drive both the availability use of water resources, leading to evolutions scarcity. The contributions can be quantified individually understand impacts around world, but also combined explore how coevolution energy-water-land affects not only driver behind scarcity changes, human interact tandem alter Here we investigate relative on under Shared Socioeconomic Pathways-Representative Concentration Pathways framework.
