Reconstruction of past climate Credit: Institute of Geography, Johannes Gutenberg University Mainz Measurements stretching back to 138 BC prove that the Earth is slowly cooling -0.3°C per millennium due to gradual changes to the position of the sun and an increase in the distance between the Earth and the sun. The climate was HOTTER in Roman and Medieval times than it is now Despite the absence of any significant amounts of human-released carbon dioxide in the atmosphere, the climate was HOTTER in Roman and Medieval times than it is now. “We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low,” says Doctor Jan Esper of the Johannes Gutenberg-Universität Mainz, one of the scientists leading the study. “Such findings are also significant with regard to climate policy.” Orbital shifting on climate up to four times as powerful as AGW (human-caused warming) The cooling effect of orbital shifting on the climate has been up to four times as powerful as anthropogenic (human-caused) warming pressures, the study concluded.
