Das wichtigste Fazit von Frederic Vester lautet:

Der Klimawandel ist kein isoliertes Umweltproblem, sondern ein Symptom eines überlasteten, stark vernetzten Mensch-Umwelt-Systems. Dauerhafte Lösungen entstehen nicht durch einzelne Massnahmen, sondern durch ein Verständnis der Rückkopplungen und durch Eingriffe (Massnahmen) an den richtigen Hebelpunkten (Steuergrössen) des Gesamtsystems.

Der wichtigste Hebel liegt dabei eindeutig in der Systemvariablen 18 Verhaltensänderung, also imWandel unseres Konsumverhaltens und unserer Wertvorstellungen.

The 3-machines energy transition model is a global system dynamics model based on energy balances,  and used to explore the energy frontiers for stabilizing the Earth's climate. The model comprises a hypothetical fossil engine, a solar engine including energy storage, and a carbon scrubber. These machines interact with Earth's carbon cycle and satisfy humanity’s energy demand. A detailed description can be accessed here: https://osf.io/fcwt8/

Simplified system dynamics model of the global carbon cycle. The model represents carbon exchange among four aggregated reservoirs: atmosphere, terrestrial biosphere, surface ocean, and deep ocean. Fossil fuel emissions enter the atmosphere as an external forcing, while internal flows redistribute carbon between the atmosphere, land, surface ocean, and deep ocean. The model is intended to explore transient behavior, natural carbon sinks, atmospheric carbon persistence, and the long-term regulating role of the ocean.

A model of Global Climate Change driven by the impact of Carbon Dioxide on the Greenhouse Effect. This model contains a physical model of energy inflows ☀️ and outflows from the Earth (primary source). And a simple model of carbon dioxide sources and sinks in the atmosphere (primary source).

The energy model assumes inflowing short-wave solar radiation that does not interact with the atmosphere. A fraction of this is reflected immediately (e.g. by snow and ice cover). The remaining is absorbed 🌎 and re-radiated as long-wave infrared which can be captured by the atmosphere ☁️. The fraction captured by the atmosphere is related to the level of Carbon Dioxide in the atmosphere.

This model tracks Carbon Dioxide emissions from burning fossil fuels 🏭 and land use changes 🚜 (e.g. deforestation). It also tracks removal of Carbon Dioxide from the atmosphere into a land sink 🌲 (e.g. vegetation) and the an ocean sink 🏖.

🧪 Experiment with different levels of emissions to see their impact on global average temperatures. You can also compare predicted temperatures and Carbon Dioxide levels to historical data.
