"Follow your inner moonlight, don't hide the madness" Allen Ginsberg

Prof. Emeritus Arie Issar

20 July 2009,

Prof. Emeritus Arie Issar received me and we had a very nice conversation at the Israeli Geological Survey in Jerusalem.

The main output can be summarized as follows:

1) Climate change is a constant. It has been observed and measured with a certain accuracy for the entire Holocene.

2) In the middle east warm weather corresponds to dry seasons. In Europe cold weather correspond to dry seasons.

3) People migration have been largely affected by climate changes. It append and it happens today as well, environmental induced migration.

4) We have to adapt, obviously migration is not an option. Adaptation is the solution.

New habits, new technologies, new production and consumption patterns.

Key words: Paleoclimatology.

He addressed me to the work of: Avram Zangvil, Bruins, Hendrik and Israel Gev.

Thanks to Arie.

Talk with Alex, Kibbutz Lotan

The subject of our conversation was the water management system in the kibbutz. The internal use of water and the external relations with relevant stakeholders (Mekorot, regional authorities and so on) . We discussed also the situation of other kibbutzim and the regional water institution system. Good time with Alex.

And surprise, Yaarit is on the front page of the kibbutz web site.

Adaptation and Adaptive trait

1. Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats.^[1]

3. An adaptive trait is an aspect of the developmental pattern of the organism which enables or enhances the probability of that organism surviving and reproducing.^[2]
