Markus Drüke

Doctoral Researcher

During my PhD I worked within the International Research Training Group (IRTG 1740) "Dynamical Phenomena in Complex Networks". At PIK I am member of the Ecosystems in Transitions (EsT) and the Earth System Model Development Group (DESM) groups in RD1.

The main task of my PhD was working with the POEM team on coupling LPJmL to GFDL‘s Earth System Model CM2Mc and investigate with the model the stability of the tropical rainforests.

An overarching goal of the project is to mobilize the existing PIK expertise from subfields such as marine biology, ocean physics, terrestrial biogeochemistry, functional ecology, and atmospheric circulation and dynamics, in order to foster a more complete and in-depth investigation of planetary boundaries and their interactions.

  • How do Earth-system components under anthropogenic pressure influence the state of the
    Earth system as a whole?
  • Are there limits and thresholds where certain combinations of processes drive the Earth
    system into altered states of operation when compared to historic precedence?
  • What are limits to change that can be established as planetary boundaries to maintain and
    safeguard the functional integrity of the Earth’s ecosphere, humanity’s one and only habitat?
  • Is there any danger of runaway effects or developments, state transitions or tipping cascades
    developing if certain thresholds of change are transgressed?
  • Which kinds of interventions into humanity’s influence on the Earth system can steer it
    toward a dynamically stabilized Anthropocene amenable to sustainable development?
