A paper published today in the Journal of Atmospheric and Solar-Terrestrial Physics finds "that the GCMs [climate models] fail to reproduce the major decadal and multidecadal oscillations found in the global surface temperature record from 1850 to 2011. On the contrary, the proposed harmonic model [based on solar system planetary motions] is found to well reconstruct the observed climate oscillations from 1850 to 2011, and it is shown to be able to forecast the climate oscillations from 1950 to 2011 using the data covering the period 1850–1950, and vice versa." The new harmonic model predicts that "The climate will likely stay steady until 2030/2040 and may warm by about 0.3-1.2 °C by 2100."
