Solar Activity Past, Present, Future
Watts Up With That? ^ | November 11, 2012 | Essay/paper by Dr. Leif Svalgaard

This image is a full-disk view of the X-ray Sun and was produced by the Yohkoh solar observatory in 1991. The structures that can be seen consist of large and hot (>2MK) coronal magnetic structures. This particular image, one of millions, shows a quite active corona from near the maximum of the solar cycle. At the upper right (solar northwest) one can see an “X-ray jet”) squirting outwards – this was one of Yohkoh’s original discoveries. (Photo credit: Wikipedia)

Essay/paper by Dr. Leif Svalgaard

Abstract

As our civilization depends increasingly on space-borne assets and on a delicate and vulnerable earth-bound infrastructure, solar activity and its potential impact becomes of increasing importance and relevance. In his famous paper on the Maunder Minimum, Eddy (1976) introduced the notion that the Sun is a variable star on long time scales. After the recent decade of vigorous research based on cosmic ray and sunspot data as well as on geomagnetic activity, an emerging consensus reconstruction of solar wind magnetic field strength has been forged for the last century. The consensus reconstruction shows reasonable agreement among the various reconstructions of solar wind magnetic field the past ~170 years.

New magnetic indices open further possibilities for the exploitation of historic data. The solar wind is a direct result of solar magnetic activity providing an important link to the effects on the Earth’s environment. Reassessment of the sunspot series (no Modern Grand Maximum) and new reconstructions of Total Solar Irradiance also contribute to our improved knowledge (or at least best guess) of the environment of the Earth System, with obvious implications for management of space-based technological assets or, perhaps, even climate. Several lines of evidence suggest that the Sun is entering a period of low activity, perhaps even a Grand Minimum. Average space weather might be ‘‘milder’’ with decreased solar activity, but the extreme events that dominate technological effects are not expected to disappear. Prediction of solar activity has a poor track record, but the progression of the current Cycle 24 is in accordance with its behaviour predicted from the evolution of the solar polar fields, so perhaps there is hope.

RE: "Something major to munch on....."
I would be a bit careful there Ernest. You could burn your lips.
I guess in due time we shall see how accurate these solar cycles are relative to the earth's climate.
I would rather not be wading around in snow up to my eyes, with 70mph cold winds blasting my little left hair into white crystal stalks. :)

Does this mean that climate change is caused by the sun, not by my two large SUVs?

” large SUVs “ large SUVs/SUNs .. yeah, I can see how the environmentalist can get the letters all mixed up and error with the fact that SUvNs can cause global warming.

Matter of fact ? why don’t we get GM or Toyota to market a new SUvNs with the name the SUN SUV ? SUN’Vs ?
