There is no doubt that the anthropogenic emissions of greenhouse gases are changing our living environment. Climate change is in our hands. We need to both work on limiting it as much as we can (mitigation), but we will also have to learn to adapt to new circumstances. TU Delft will harness its innovative powers to support the world-wide transition to non-fossil resources, and adaptation of the living environment to the consequences of global warming. The problem is complex and urgent – but we have no other choice than to be optimistic and use all of our capacity to face the challenge, through our education programs and our research.
