Historical geomagnetic and climate records were analyzed to study long-term trends and relationships with solar activity. Wavelet technique and recurrence plot analysis are applied to the data to find their coherence and similarities at different times and time-scales. It is shown that the solar cycle signal is more pronounced in climatic data during the last 60 years.
