Solar induced climate fluctuations are crucial to life in earth. When weak solar cycles are predominant on the sun, cooling occurs on the earth. The present solar cycle number 23 is the first of a weak cycles series on the sun. This eventually will lead to drops in the solar energy budget received by the earth including drops in solar irradiance, UV radiation which plays a vital role in photosynthesis and IR radiation.
Biological effects will happen on the earth. It is found that fish population is very much controlled by the Solar  (80-120 year) Wolf-Gleissberg cycles.
The problem of disappearance of sardine from the eastern Mediterranean in 1964 previously attributed to the side effects of the High Dam can be explained in the context of sun-earth connection. Sardine disappeared at the same time from the coasts of California, Japan and Chile. Also contemporary herring fish disappearance occurred in the North Sea off the shores of Norway and Siberia. Solar induced climate change occurred at the same time with change in the general wind circulation.
