Time Travel and Climate: Changing the Past to fix the Future

SAPEA – Science Advice for Policy by European Academies | AC Coppens, Peter Lund, Nebojsa Nakicenovic

How could a time machine help us reinvent our energy system?

What would you do if you invented a time machine? Would you travel back to the past to alter history or fix mistakes? Or would you rather jump forward, to collect future knowledge and bring back advanced technologies?

Led by the audience, we will be asking these and other challenging questions to two of Europe’s top experts on climate change and energy: Professor Nebojsa Nakicenovic, Chief Scientific Advisor to the European Commission, and Professor Peter Lund, co-chair of the SAPEA working group on Europe’s energy transition.

How did we get ourselves into such a mess with climate change? When and how did it all go wrong — and could we have done otherwise? What information about the future do we need to help guide our energy choices now? And how do today’s scientists model tomorrow’s world without the aid of a time machine?

The event will be hosted by AC Coppens, an experienced moderator who will make sure that the full audience — including those in the room and those joining via YouTube livestream — can actively engage with the experts and take part in lively conversation.



This event can be attended digitally via livestream or in-person with a limited on-site audience at the Museum of Natural History. If you would like to attend the event, please book your spot here and indicate if you would like to join on-site or virtually.

Then simply follow this link to the YouTube livestream and post your question in the chat.


Due to the current situation, we are required to ask for the contact information of each person entering the Museum of Natural History in accordance with the Protection Against Infection Act. We therefore require the following data from all persons who register: First name, last name, address, telephone number and email address.

On-site the protective and hygienic measures of the Museum of Natural History apply. The so-called 3G rule (for “geimpft, genesen oder getestet“, i.e. “vaccinated, recovered or tested”) will be applied: Anyone who is not fully vaccinated or is not considered recovered will be required to provide a recent negative Covid-19 test. Visiting the event is permitted with a medical face mask only.

The registration data will be stored by SAPEA for the purpose of organizing the event as well as for any subsequent contact follow-up and will also be shared with the organizers of Berlin Science Week and the Museum of Natural History for this purpose.

We will take pictures and videos on the Campus on 5/6 November, which we will use for documentation and communication purposes, and will livestream the events on our website. If you do not agree, please send your denial to via email to info@berlinscienceweek.com prior to the Campus. We also refer to our data protection regulation.
