#FridaysForFuture I'm a German scientist for future. Very concerned about dangers to coming generations through CO2, nuclear waste, nuclear war, mass extinction. Sustainability dear to my heart since reading "limits to growth" in 1978, never owned a car in my life. #hamradio#AmateurRadio QRP 5W inner city apartment amateur radio station. Enjoy #MorseCode, rag chewing, mining RBN / PSKreporter data, #JS8, low-mountain hiking (#GMA). You can see me at German #AfuBarcamp if you take part in those.
I just realize there's no description of my profile picture online yet:
The face of a male in his early sixties with white hair and beard, looking into the world with interest and curiosity, the face showing what he hopes passes as a friendly smile.
