Ever Think You Should Do More Now to Save the World?

NOTE RE SCHEDULE: If Sunday evening is impossible, please suggest a 1st, 2nd, 3rd choice.
A 4 session (but possibly ongoing weekly session) to enable people to do the following: 1) meet others who realize they need to do more than they are now doing beyond their own lifestyle changes for any realistic hope to avert the otherwise worstcase climate catastrophe now predicted by virtually all climate scientists; and to share your feelings, thoughts, needs, and perspectives as well as to get some deeper empathy and perspectives
2) to learn relevant and inspiring social change history and political science knowledge about what has worked in the past to have achieved humanity's greatest advances despite huge opposition;
3) to hear from leaders of major campaigns with chapters in Berlin as to why they think their strategy is best and for whom; and
4) to schedule special meetings for other topics that might come up, for example the potential of coalition with campaigns addressing the other and far more imminent and now all too likely threat to the survival of life on earth, namely inadvertent nuclear war from either the war in Ukraine or a near future confrontation between the US and China
