Well here I'll sum it from another article I found.
New Little Ice Age by 2030! Analysis of the sun's activity in the last two millennia indicates that, contrary to the
IPCC's speculation about man-made global warming, that we could be headed into
a Maunder minimum type of climate (a Little Ice Age).
The probability is high that the minima around 2030 and 2201 will go along with
periods of cold climate comparable to the nadir of the Little Ice Age, and La Ni�as
will be more frequent and stronger than El Ni�os through 2018 (Landscheidt, 2000).
We need not wait until 2030 to see whether the forecast is correct, however. A
declining trend in solar activity and global temperature should become manifest long
before then. The current 11-year sunspot cycle 23 with its considerably weaker
activity seems to be a first indication of the new trend, especially as it was predicted
on the basis of solar motion cycles two decades ago. As to temperature, only El Ni�o
periods should interrupt the downward trend, but even El Ni�os should become less
frequent and strong.
The total magnetic flux leaving the Sun has risen by a factor of 2.3 since 1901 while
global temperature on earth increased by about 0.6�C. Energetic flares increased the
Sun's ultraviolet radiation by at least 16 percent. There is ?a clear connection between
solar eruptions and a strong rise in temperature.?
Lake bottom cores from the Yukatan Peninsula covering more than 2,000 years
show a similar correlation between recurrent droughts and the Sun's eruptional
activity. These results and many earlier ones (Landscheidt, 1981-2001) document
the importance of the Sun's eruptional activity on climate.
Energetic solar eruptions do not accumulate around the sunspot maximum. In most
cycles they shun the maximum phase and can even occur close to a sunspot minimum.
I (Landscheidt) have shown for decades that the sun's varying activity is linked to cycles in its irregular oscillation about the centre of mass of the solar system (the solar
retrograde cycle). As these cycles are connected with climate phenomena and can be
computed for centuries, they offer a means to forecast phases of cool and warm
climate.
Researchers need to take the sun seriously as a factor in climate change, including
warming, droughts, and cold snaps.
