2. Climate change impacts I

Key climate impacts and indirect impacts

In this lecture, we cover the main impacts of climate change. On a given territory, climate change can have basically two types of impacts:

  • Direct impacts, such as floods, heat waves etc. These impact directly affect the territory
  • Indirect impacts, i.e. impacts which indirectly affect a territory via trade, the movements of population etc. They include population migrations, the risk of war, the destabilization of food markets etc.

Both direct and indirect impacts can affect cities, but the adaptation strategies are competely different.
