THE SOLAR CYCLE CLIMATE LINK: CONFIRMED! PDF Print E-mail

September 4, 2009: "Amplifying the Pacific Climate System Response to a Small 11-Year Solar Cycle Forcing" in Science (28 August 2009, Vol. 325, No. 5944, pp. 1114-1118), by Gerald A. Meehl, Julie Arblaster, Katja Matthes, Fabrizio Sassi and Harry van Loon.

Many climate realists ("skeptics") assert that there is potential for climate change/AGW to be driven by solar influences, including not only total irradiation, for example, but also variations in solar cycles (length, number of sunspots, etc.). Those assertions have been routinely dismissed out-of-hand by AGW proponents, and by various activist groups. Thanks to researchers Meehl, et al., at the National Center for Atmospheric Research (NCAR), the reality is now more clear. Their recent report in Science presents results of study into how the Sun, the upper atmosphere (stratosphere) and the oceans interact. In their new publication, the authors identify mechanisms that act together increasing the effect on Earth's climate that had previously been considered "too small" for concern.

Meehl notes that: "With the help of increased computing power and improved models, as well as observational discoveries, we are uncovering more of how the mechanisms combine to connect solar variability to our weather and climate."

One more IPCC uncertainty for which evidence has been discovered that suggests the science is not yet really "settled."
