Most scientists think the greenhouse effect causes global warming as on Venus, but is there a contribution from sunspot cycles?

Long cycles in sunspots and other solar activity may have affected the Sun's energy output and Earth's climate.

Several times over the last 500 years low sunspots numbers have coincided with much cooler global temperatures. Is there a connection or is it coincidence?

Scientists have evidence that the Little Ice Age resulted from changes in the Sun's energy output associated with long term sunspot and other solar activity cycles.

Proxy studies and anecdotal evidence must be used to reconstruct past climates and provide evidence for the Little Ice Age.

Many stars are variable stars that change brightness. Any possible solar variations must be very small, but does the Sun's energy output vary?

Faculae are bright regions on the Sun's photosphere affecting solar energy output. Changes in the number of faculae and sunspots may play a role in global climate change.

In 2008, no sunspots were observed on 266 of the year's 366 days (73%), a low surpassed only in 1913, which had 311 spotless days (85%).

What is the solar cycle and how long does it last? What are the effects of the sun's changing cycle?

Most climate scientists agree that the late 17th century was the Little Ice Age, but there is some disagreement on the exact beginning and end.

Climate changes occur as part of the Earth's normal climate cycle, in a slow transitional method. Abrupt climate change has happened in the past due to various effects.

There may be a lot about the effects the Sun has on our planet that you simply didn't know.

The Little Ice Age caused decreased winter temperatures, resulting in sea ice, glacier advances, and crop failures. Discover what caused this abrupt change in climate.
