Abstract
We estimate the magnetic activity of the Sun that will decrease seriously in the next two or three cycles, leading to a deep minimum. Three arguments are given in favor of this statement. With the approach of a deep minimum the Earth ocean temperature may gradually decrease by at least 1degreesK. However, due to the increase of the greenhouse effect one may expect during the coming decennia only a small decrease, say 0.5degreesK. Nevertheless this may be interpreted wrongly as if the greenhouse effect is irrelevant and that the present high ocean temperature is only a casual fluctuation. Governments may then allow an ever increasing use of Earth fuel, leading to an ocean temperature higher than at present after half a century. After the deep minimum an extra increase in temperature of at least 1degreesK is to be expected leading to drastic, if not catastrophic, effects. It is concluded that (1) more research on the activity of the Sun is required as well as more research on the greenhouse effect; (2) the need for nuclear fusion is imperative.
