Which plays a stronger role in its impact on climate – atmospheric CO2 or changes in albedo?
Dr. Soon: If you change planetary albedo by as little as one or two percent, it has the same effect as doubling atmospheric CO2. The warming we’ve experienced in the late 20th century could just as easily be explained by small decreases in cloud cover – natural changes in the system –and have nothing to do with CO2. Examiner.com: You have developed a theory showing a close correlation between solar radiation and temperatures in the arctic and surrounding regions – and, perhaps, even globally. Would you like to explain it? Dr. Soon: In 2005, I discovered a surprisingly strong correlation between solar radiation and temperatures in the Arctic over the past 130 years. Since then, I have demonstrated similar correlations in all the regions surrounding the Arctic, including the U.S. mainland and China. The close relationships between the abrupt ups and downs of solar activity and of temperature that I have identified occur locally in coastal Greenland; regionally in the Arctic Pacific and n
