Master seminar 2025 - "Weather Modification and Geo Engineering"

Now:

  1. Look for a second paper connected to your selection
  2. Discuss with your advisor (see below) the secondary literature you plan to use for your presentation soon, well in time before the final preparation of the slide material. Contact the advisor with suggestions.
  3. We suggest to talk to your advisor at least one more time before the seminar. You should go through preliminary presentation material in time for last changes.
