Figure 3: The mean yearly (MAAT) temperatures at Svalbard (Spitzbergen)—for the year and the four seasons. The red circles are the mean temperatures in sunspot cycles with standard error bars, also used for the correlation analysis. The red thick lines are weighted linear least square fits to the solar cycle mean temperatures, with the trends for the period 1914–2008 ( ) indicated. The black dashed curves are data before 1914 and after 2008, corresponding to incomplete solar cycles, and not used in the averaging. Forecasts for SC24 temperatures based on length of SC23 are given with 95% confidence intervals (diamonds with bars) for the year and winter temperatures.
