Appendix – Expert surveys
Climatic change scenarios upon which the questionnaires were based. These scenarios were divided according the field of expertise of the reviewer. They included: terrestrial, marine and freshwater ecosystems.
Questionnaire introduction: According to the Israel Climate Change Information Center and despite the differences in predictions of various climate change models, there is general agreement regarding the following future trends:
- Continuing trend of warming in the next few decades at a rate of 0.50C per decade
- Decrease in the amount of annual rainfall, up to 15%, in the next few decades.
- Increase in variability of various rainfall parameters (annual amounts, number of rainy periods and their intensity, length of rainy season and dry spells). These trends are marginally significant.
