Balancing processes, resolution and ensembles in Earth system models
Jean-François Lamarque
Using recent simulation results and model developments, this talk will discuss the present challenges that Earth System modeling group are facing in creating and using the next generation of Earth system models, in particular in the light of the upcoming CMIP6.
Improving understanding of historical and future terrestrial carbon sinks with the GFDL Earth system models
Elena Shevliakova
As anthropogenic emissions of CO2 are increasing, terrestrial systems continue to uptake about a quarter of those emissions, with another quarter going to the oceans. To understand the interplay between natural terrestrial and marine biosphere processes, land use land cover change (LULCC) and changing climate, NOAA/GFDL has developed fully coupled, comprehensive climate-carbon cycle models (i.e., an Earth System Model (ESM)), capable of prognostically simulating the transient physical climate, and the exchanges of CO2 among land, ocean and atmosphere, as well as feedbacks between the climate and carbon system. Previous studies indicate that enhanced vegetation growth under elevated atmospheric CO2 and LULCC are the key drivers of the future land carbon sinks. These sinks, in turn, will have implications for the 21st century evolution of the atmospheric CO2 concentrations and climate warming. Here we present insights from the GFDL ESMs on the implications of enhanced vegetation growth and LULCC for the historical and future land sinks and how the two are interrelated.
Representing hydrologic processes and their interactions in Earth system models
Ruby Leung
By controlling the partitioning of surface energy fluxes, terrestrial processes play an important role in the global and regional water cycle.  To understand and quantify the terrestrial water cycle and its interaction with human activities that drive future changes in the coupled system, we have undertaken research to improve the representation of hydrologic processes in Earth system models. This presentation will discuss our efforts to improve hydrologic modeling, add new representations of human influence, and couple the human and hydrologic components in the framework of the Community Land Model (CLM). With our framework for modeling the impacts of climate change and water use on the water cycle, we evaluated the implications of climate change mitigation to water scarcity. Building on our capability, new development is focusing on extending our river transport model to represent inundation dynamics, riverine biogeochemistry, and coupled hydrology-vegetation system, with the goal for a flexible modeling framework useful for science discovery as well as addressing societally relevant questions.

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
