Abstract. The Scenario Model Intercomparison Project (ScenarioMIP) defines and coordinates the main set of future climate projections, based on concentration-driven simulations, within Coupled phase 6 (CMIP6). This paper presents a range its outcomes by synthesizing results from participating global coupled Earth system models. We limit our scope to analysis strictly geophysical outcomes: mainly averages spatial patterns change for surface air temperature precipitation. also compare CMIP6...

[1] The hydrological impact of enhancing Earth's albedo by solar radiation management is investigated using simulations from 12 Earth System models contributing to the Geoengineering Model Intercomparison Project (GeoMIP). We contrast an idealized experiment, G1, where global mean radiative forcing kept at preindustrial conditions reducing insolation while CO2 concentration quadrupled a 4×CO2 experiment. reduction evapotranspiration over land with instantaneously increasing concentrations in...
Abstract Solar geoengineering—deliberate reduction in the amount of solar radiation retained by Earth—has been proposed as a means counteracting some climatic effects anthropogenic greenhouse gas emissions. We present results from Experiment G1 Geoengineering Model Intercomparison Project, which 12 climate models have simulated response to an abrupt quadrupling CO 2 preindustrial concentrations brought into radiative balance via globally uniform insolation. Models show this largely offsets...

Abstract Wide disagreement among individual modeling studies has contributed to a debate on the role of recent sea ice loss in Arctic amplification global warming and Siberian wintertime cooling trend. We perform coordinated experiments with six atmospheric general circulation models forced by observed climatological daily concentration surface temperature. The results indicate that impact decline is rather limited high‐latitude lower troposphere winter, changes do not significantly lead...
Abstract. Many modelling groups that contribute to CMIP6 (Coupled Model Intercomparison Project Phase 6) have found a larger equilibrium climate sensitivity (ECS) with their latest model versions compared the values obtained earlier used in CMIP5. This is also case for EC-Earth model. Therefore, this study, we investigate what developments since CMIP5 era could caused increase ECS Apart from increases horizontal and vertical resolution, has substantially changed representation of aerosols;...
Abstract. This paper documents the global climate model EC-Earth3-AerChem, one of members EC-Earth3 family models participating in Coupled Model Intercomparison Project Phase 6 (CMIP6). EC-Earth3-AerChem has interactive aerosols and atmospheric chemistry contributes to Aerosols Chemistry (AerChemMIP). In this paper, we give an overview model, describe detail how it differs from other configurations, outline new features compared with previously documented version (EC-Earth 2.4). We explain...
Abstract As climate change accelerates, societies and climate-sensitive socioeconomic sectors cannot continue to rely on the past as a guide possible future hazards. Operational decadal predictions offer potential inform current adaptation increase resilience by filling important gap between seasonal forecasts projections. The World Meteorological Organization (WMO) has recognized this in 2017 established WMO Lead Centre for Annual Decadal Climate Predictions (shortened “Lead Centre” below),...
Blocking of the tropospheric jet stream during Northern Hemisphere winter (December‐January‐February) is examined in a multi‐model ensemble coupled atmosphere‐ocean general circulation models (GCMs) obtained from Coupled Model Intercomparison Project Phase 5 (CMIP5). The CMIP5 exhibit large biases blocking frequency and related latitude, similar to earlier generations GCMs. Underestimated at high latitudes, especially over Europe, common. In general, model decrease as resolution increases....
Ocean wind waves follow shifts in atmospheric circulation and regimes caused by climate change variability. We use a wave model (WAM) forced winds from an Earth system (EC‐Earth) to study the evolution of global terms trends speed height, their rates anomalies over 250 years. Historical period future scenarios (RCP8.5 RCP4.5) are calculated within fifth phase Coupled Model Intercomparison Project. Both indicate increase height Arctic Southern decrease Pacific Ocean. Some regions, e.g., North...
Global-scale solar geoengineering is the deliberate modification of climate system to offset some amount anthropogenic change by reducing incident radiation at surface. These changes planetary energy budget result in differential regional effects. For first time, we quantitatively evaluate potential for disparities a multi-model context using results from model experiment that offsets forcing quadrupling CO2 via reduction irradiance. We temperature and precipitation 22 geographic regions...
Abstract The methods to quantify equilibrium climate sensitivity are still debated. We collect millennial‐length simulations of coupled models and show that the global mean warming is higher than those obtained using extrapolation from shorter simulations. Specifically, 27 with 15 forced a range CO 2 concentrations median 17% larger estimated first 150 years spatial patterns radiative feedbacks change continuously, in most regions reducing their tendency stabilizing climate. In equatorial...
Temperature and precipitation extremes are examined in the Geoengineering Model Intercomparison Project experiment G1 , wherein an instantaneous quadrupling of CO 2 from its preindustrial control value is offset by a commensurate reduction solar irradiance. Compared to climate, changes climate under generally much smaller than 4 × alone. However, it also case that temperature differ significantly those conditions. Probability density functions standardized anomalies monthly surface exhibit...
Abstract We present a model intercomparison project, LongRunMIP, the first collection of millennial-length (1,000+ years) simulations complex coupled climate models with representation ocean, atmosphere, sea ice, and land surface, their interactions. Standard are generally only few hundred years long. However, modeling long-term equilibration in response to radiative forcing perturbation is important for understanding many phenomena, such as evolution ocean circulation, time-...
Abstract The climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus been set on role thickness, although it strongly determines surface heat fluxes. Here ensembles simulations using EC‐Earth atmospheric model (Integrated Forecast System) are performed and analyzed to quantify impacts thickness change since 1982 as revealed by assimilation Global Ice‐Ocean Modeling Assimilation System. Results show that recent thinning...
Abstract Many nations responded to the corona virus disease‐2019 (COVID‐19) pandemic by restricting travel and other activities during 2020, resulting in temporarily reduced emissions of CO 2 , greenhouse gases ozone aerosol precursors. We present initial results from a coordinated Intercomparison, CovidMIP, Earth system model simulations which assess impact on climate these reductions. 12 models performed multiple initial‐condition ensembles produce over 300 spanning both condition...
Abstract. As global warming is proceeding due to rising greenhouse gas concentrations, the Earth system moves towards climate states that challenge adaptation. Past are offering possible modelling systems for of coming decades. These include mid-Pliocene (∼ 3 Ma), last interglacial 129–116 ka) and mid-Holocene 6 ka). The simulations these past warm periods key experiments in Paleoclimate Model Intercomparison Project (PMIP) phase 4, contributing Coupled (CMIP6). has long been regarded as a...
