The many periods in the variation of the Earth's global temperature
Abstract
At least 20 distinct harmonic variations are present in the Earth's global temperature record between years 1850 and 2008 (Kjeldseth-Moe and Wedemeyer-Bühm, 2009). Here we report on the significance of the determined periods, and look for further and less prominent variations that may also be real. We furthermore investigate long time series of measured local (i.e. non-global) temperatures for periodic variations and compare the results to the global temperatures. The variable energy input required in maintaining the global temperature variations is estimated and compared with variable thermal and non-thermal forcing resulting from solar activity.
