What About the Sun & Max Planck & Nature?
David posted the following comment this morning at this blog:
“We know that the globe is warming very rapidly (~0.2C/decade), and that this warming has occured in the absence of any natural forcing process and is occuring about 10 times faster than the sustained warming at the end of the last ice age.”
And it reminded me of this press release from the Max Planck Institute which is only a couple of years old now.
Titled ‘The Sun is More Active Now than Over the Last 8000 Years’ it includes comment that:
“An international team of scientists has reconstructed the Sun’s activity over the last 11 millennia and forecasts decreased activity within a few decades
The activity of the Sun over the last 11,400 years, i.e., back to the end of the last ice age on Earth, has now for the first time been reconstructed quantitatively by an international group of researchers led by Sami K. Solanki from the Max Planck Institute for Solar System Research (Katlenburg-Lindau, Germany). The scientists have analyzed the radioactive isotopes in trees that lived thousands of years ago. As the scientists from Germany, Finland, and Switzerland report in the current issue of the science journal Nature from October 28, one needs to go back over 8,000 years in order to find a time when the Sun was, on average, as active as in the last 60 years. Based on a statistical study of earlier periods of increased solar activity, the researchers predict that the current level of high solar activity will probably continue only for a few more decades.
I was also reminded of this Max Planck media release when I read page 3 of The Australian on 27th March and a piece titled ‘Beachgoers back latest theory on brighter sun’. This story quotes a Martin Wild of the Institute of Atmospheric and Climate Science in Zurich, Switzerland.
