Chill Hours Record: A Sensitive Method for Climate Change Indication

Global and regional climate change of which worming, supplied water availabilities, drought, floods, health and food safety, are mostly on top of present human society critical constrained concerns. That issue initiated scientific community mass mobilization aimed at case studies as well as forwarding mission achievement of mitigation. The indicated climate change foresee require sensitive early signs of which Chill Hours (CH) analysis is recommended. This paper presents an evaluation of temporal and spatial CH record from the Hula valley, a part of the Lake Kinneret drainage basin and discuss precautions of mild environmental exceptional warning of climate change sign factors. These retroactive warning notices included temperature increase, headwater yield reduction and changes of nutrients migration dynamics from the Hula valley into Lake Kinneret.
