Abstract
THE equatorial solar rotation speed, estimated from observations made over the past 10 years of the sunspot longitudinal motions over the solar disk, has shown a tendency to increase as relative sunspot numbers decreased. During these years, covering most of solar cycle no. 20 (1965–76), the magnitude of the solar rotation speed averaged annualy showed a good inverse correlation with the annual relative sunspot numbers. I suggest here that this variation of the equatorial solar rotation speed may be responsible for the Earth's present unusual climatic conditions.
