Transitioning Into The ANthropocene (TITAN)

Transitioning Into The ANthropocene (TITAN)

Learning about the climate system from data of the 19th and early 20th century.

11-13 Sep 2017: TITAN Meeting, Edinburgh


This TITAN meeting in Edinburgh reviews progress in the project and discusses the next steps. The first two days (11-12 Sep 2017) are focussed on presentations and discussions, while the third day (13 Sep 2017) will be a social activity.

Venue: Room 302, Crew Building, Edinburgh (directions…) – go up the stairs, turn right, and room 302 is in front of you.

Wed, 13 September 2017 – Social outing

We plan a day out to a picturesque location outside Edinburgh, with some light walking.

Travel and accommodation

The meeting will be in the Crew Building, King’s Buildings Campus, the University of Edinburgh. To get there, please see the travel information on the University website.


Edinburgh has a huge number of hotels and guesthouses in the centre, but the King’s Buildings Campus is in a quieter residential area to the South. Hotel recommendations within walking distance (600 metres/0.4 miles) are:
