Sunspot cycle and climate
WebDec 31, 2024 · The number of sunspots rises and falls as part of a roughly 11-year solar activity cycle. There are many sunspots – and more associated emissions of UV and X-rays – at solar maximum and few or even no sunspots at solar minimum. The solar magnetic field also varies in strength with this solar cycle. WebNov 1, 1991 · It has recently been suggested that the solar irradiance has varied in phase with the 80- to 90-year period represented by the envelope of the 11-year sunspot cycle and that this variation is causing a significant part of the changes in the global temperature. This interpretation has been criticized …
