Completely independently of this oceanographic data, a simple correlation analysis (Foster and Rahmstorf ERL 2011) showed that the flatter warming trend of the last 10 years was mostly a result of natural variability, namely the recently more frequent appearance of cold La Niña events in the tropical Pacific and a small contribution from decreasing solar activity.

«It could therefore be concluded that both the decreasing correlation between sunspot number and geomagnetic activity, and the deviation of the global temperature temperature long - term trend from solar activity as expressed by the sunspot index are due to the increased number of high speed streams of solar wind on the decreasing phase and the minimum of sunspot in the last decade.»

An increasing aerosol load due to human activities decreases regional air quality and the amount of solar radiation reaching the Earth's surface.

Such lulls in solar activity, which can cause the total amount of energy given off by the Sun to decrease by about a tenth of a percent, typically spur surface temperature to dip slightly.

Bull ---, are you capable of seeing that the time - integral of solar activity decreased from 1940's to 1970's?

Cause and effect if far more plausible — i.e., the Earth takes on heat during times of increased solar activity and gives up heat when solar activity decreases.

-- August 16, 2008 — Excerpt: An expert from the National Autonomous University of Mexico predicted that in about ten years the Earth will enter a «little ice age» which will last from 60 to 80 years and may be caused by the decrease in solar activity.

Note, for example, how the temperature trend in the first decade of the 21st century was generally flat because an upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans absorbed more heat than usual from the atmosphere (sea water temperatures continued to rise).»

Increased or decreased solar activity would increase or decrease the amount of energy being transferred to the Earth's magnetic field.

All of this will be over by 2015, when the records of 2010 and 1998 will have been obliterated by increased solar activity, ENSO and decreased albedo as we go into virtually ice free arctic summers, oh and increased GHG concentrations of course.

The mechanism proposed for the linkage of Solar activity with Earth's rotation is the interaction of Solar Wind with the Earth's magnetosphere; the decrease in Solar Wind at sunspot minima weakens the interaction with the magnetosphere that allows the Earth to speed up, and the increase in Solar Wind at sunspot maxima strengthens the interaction with the magnetosphere that slows down the spinning of the Earth.

As for solar activity, it has decreased in the second half of the 20th century after the 1957 — 1958 maximum, and it is low in recent years.

We had the warm ENSO period of the 1980s / 1990s (which led to the all - time record warm year 1998), an observed decrease in late 20th C cloud cover (and albedo), the highest solar activity for several thousand years, etc..

You get the information to decide what parts of the astronomical cycles cause a decrease in solar activity from solar activity records, and then propose that those configurations cause a decrease in solar activity.
