P. Gosselin: Scientists Say A Grand Episode In Solar Activity Started in 2008 – But No Support For A Grand (Maunder-Type) Minimum

Cornelis De Jager of the Royal Netherlands Institute for Sea Research and Silvia Duhau of the Departamento de Física, Facultad de Ingenieria, Universidad de Buenos Aires have published a new paper in the Journal of Space Weather and Space Climate titled:
Sudden transitions and grand variations in the solar dynamo, past and future.
I'm not sure if other bloggers have written about this. If so, here it is again. The paper forecasts solar activity for the current Solar cycle 24, which they expect will peak in May, 2013 with a maximum sunspot number Rmax of 62 ± 12.
More importantly, the authors write (emphasis added):
The subsequent analysis, based on a phase diagram, which is a diagram showing the relation between maximum sunspot numbers and minimum geomagnetic aa index values leads to the conclusion that a new Grand Episode in solar activity has started in 2008."

P. Gosselin: Yet Another Paper Shows "The Enormous Importance Of Solar Activity Fluctuations On Climate"

Figure 1: Reconstruction of precipitation amounts for the edge of the Tibet Plateau. The bars on the chart depict prominent weak phases of solar activity, which correspond to Om = Oort Minimum; Wm = Wolf Minimum; Sm = Spörer Minimum; Mm = Maunder Minimum; Dm = Dalton Minimum). Figure from: Sun & Liu (2012).
Yet another study has appeared in the Journal of Geophysical Research, this one looks at the precipitation history on the Tibet Plateau of the last 1000 years.
Geologist Dr. Sebastian Lüning and chemist Prof. Fritz Vahrenholt have written a summary of this paper, which I've translated in the English.
P. Gosselin: PNAS Study Shows Powerful Correlation Between Sun And Climate Over The Last 9000 Years

Figure 1: Comparison of solar activity (blue curve) and the Asian climate development (green curve, delta 18O of a stalagmite in a Chinese cave) for the last 9000 years (both curves normalized). One clearly sees a good agreement between the two curves, which stgrongly suggests a significant climate impact by the sun. Figure from Steinhilber et al. (2012).

The IPCC thinks the sun plays nary a role on climate and that anthropogenic factors explain almost the entire warming since 1850.
It's been completely ignored that Gerard Bond was able to show more than 10 years ago that the last 10,000 years have been characterized by a global temperature roller coaster that runs up and down in sync with solar activity (Bond et al. 2001).

No surprise here. Just more inconvenient results for CO2 broken-record dogmatists
New paper: GISS temps and solar activity
A recent paper published by the Journal of Atmospheric and Solar Terrestial Physics (74) 2012 87-93 and authored by Souza Echer et al. suggests that solar cycles, to a substantial extent, drive global temperatures, and that likely through amplification mechanisms.
The paper is titled: On the relationship between global, hemispheric and latitudinal averaged air surface temperature (GISS time series) and solar activity.
The authors decomposed average air surface temperature series obtained from GISS and sunspot number (Rz) from 1880 – 2005 to see if a correlation could be found. They performed a cross correlation analysis between band-passed filtered data around 11-year and 22 years.

P. Gosselin: Signs Of Strengthening Global Cooling by Matti Vooro

The entire planet has stopped warming since 1998 and, more significantly, has started to cool since 2003. Instead of warning people of cooler weather for the next 30 years, there's still the distinct false sense of expectation of unprecedented warming. People and governments are being urged to go entirely in the wrong direction for the wrong reasons – and at a potentially horrendous price.
Just look at what happened in UK. Ten years ago Britons were told to expect global warming only and that snow would be a thing of the past. Yet the opposite has arrived, three winters in a row. This winter it crippled the entire nation for nearly a month in December 2010.
