While carbon is necessarily included as the basic building block of ecosystems undergoing terrestrial and oceanic chemistry, associated chemical and ecological tracers which control nutrient limitation, plant biomass, productivity, and functional composition are also included.

Such changes that take place within an ecosystem are referred to as events.Figure: Major natural and anthropogenic processes and influences on the climate system addressed in scenarios.The climate system consists of five interacting components: the atmosphere, the hydrosphere, the cryosphere, the land surface and the biosphere.Impacts on ecosystems, natural resources, economic activities and infrastructure, and human well-being, depend not only on climate change, but also on other changes in the environment (depicted in environmental scenarios) and the capacity of societies and economies to buffer and adapt to impacts (addressed in scenarios of vulnerability and adaptive capacity). Our first prototype model, ESM2.1, evolved directly from GFDL’s successful CM2.1 climate model ().Closer integration of scenarios is required to address feedback loops and other issues, such as the ecological and economic implications of different sets of adaptation and mitigation policies. Building on this, we produced two new models representing ocean physics with alternative numerical frameworks to explore the implications of some of the fundamental assumptions embedded in these models.

This two-way cause and effect relationship between an event and a sphere is called an interaction.
