Less sun spots, less magnetic flux, weaker polar jet stream, colder winter, colder winter, cooler summer, ice build up in norther hemisphere, more albedo, negative temperature feedback. And if you look at the weakening polar jet stream due to diminishing sun spots happening right now, you get the idea what is going to cause the next little ice age which should start in about 10 to 20 years. We are getting record cold temperatures in northern hemisphere due to stronger polar vortex.

The jet stream isn't weakening. It hasn't changed it's position from the usual variations either. The 'polar vortex' is a news media term. Polar highs are normal. The 'vortex' is normal.

Ice ages occur due to changes in the eccentricity of Earth's orbit. We aren't due for another one for at least 40,000 years. We are currently moving toward a more circular orbit. We should get there in about 2000 years.

While the sunspots do cause increased solar activity and a general increase in the emission of the sun this is not a large effect. The changes in climate can be explained entirely by the sunspot activity combined with the Milankovitch Cycles.

The orbit of the Earth around the Sun is not perfectly round. And the orbit of the Moon can get in the way of the Sun's emissions. Also there is a tilt of the axis of the Earth that can place the Northern or the Southern hemispheres pointed more directly at the sun.

All of these things combine to cause most of the climate variations that are totally secondary to the cloud patterns which are caused by the moisture content of the atmosphere on this water planet.

Sunspots ARE solar activity, Wake. One does not cause the other. They are the same thing.

Maybe. So far as we've measured, this seems to be true, but we haven't been measuring the output of the Sun for very long.

The effect, if any, is unknown. There does, however, seem to be a correlation between sunspots and nicer weather.

There is no such thing as a global climate, Wake. There is no such thing as a global weather. I think you mean global temperature (which is unknown, but it certainly can vary).

Certainly one source of variance of global temperatures.

Irrelevant, Wake. Seasons are not climate.

Only during an eclipse, Wake. That usually only lasts for a minute or two. I attended the totality of the last one in the U.S. Fantastic show!

Cloud patterns follow their own variance and the seasons, Wake.

It is not possible to measure the global humidity of Earth, Wake.
