Solar Output project help?

I have a project about solar output but have no clue what to do and I have looked everywhere. Basically, the 3 questions are "How does solar output cause an effect on global climate?", "For how long does it have an effect on climate?",

Answers:

del

The output of the Sun varies by only a fraction of 1%, but, its effects are amplified by the fact that it warms up the upper atmosphere more than the lower atmosphere, suppressing clouds. The best evidence is that up to the mid twentieth century that solar activity had a very good correlation to global average temperature, but, since then, the effects of humans burning fossil fuels has overwhelmed the effects of solar activity on temperature.

Well without the Sun we would not have much of a climate to speak of, and we would not be here to not speak of it.

http://lmgtfy.com/?q=solar+output
Solar output is the total output of the sun, including infrared, visible light, and ultraviolet.
The Little Ice Age was caused by a slight reduction in solar output.

Real Ice Ages are caused by Milankovitch cycles as the earth's orbit changes from nearly circular (as it is now) to more elongated, which causes the earth to receives less solar radiation.
https://en.wikipedia.org/wiki/Milankovit...

The earth receives radiation from the sun, and there is a minimal amount of heat that comes from the hot core of the earth. Earth also radiates energy - if you've walked on the road after dark in bare feet, you can feel that it's still hot, but over time it cools as it radiates some of that heat away. When the amount lost to radiation = the amount received from the sun + from the core, then there is an equilibrium, and the temperature, averaged over the entire earth, is pretty stable.

Clouds prevent some heat from the sun from reaching the surface of the earth. If you've watched, you know that when it's cloudy at night, it does not get as cold. Clouds prevent earth from losing as much heat. Both water, and CO2 in the atmosphere, reduce the amount of infrared energy that the earth can radiate. What has changed over the last century, and more, the last few decades, is the amount of CO2 in the atmosphere. What that's done is reduce the amount of energy that the earth is able to radiate away, so the earth is heating up.

https://en.wikipedia.org/wiki/Global_war...

BTW, anyone who talks about millions, or billions, of years is going to try to mislead you.
Global warming caused by burning fossil fuel releasing CO2 into the environment has only been happening on the scale it is today for a few decades.

Our Earth would be a frozen ice ball without solar radiation.
Solar radiation drives the water cycle (google it)
It lasts forever, well billions of years anyway.

see climate.nasa.gov or google with SITE:EDU to get university papers. Basically, the Sun is the source of energy, it varies over time. One of the cycle is a 11 year sunspot cycle. Another is the distance from the the earth to the sun and inclination- That is a longer term thoussand year cycle- The Milankovitch cycles that trigger ice ages. The atmosphere has a tremendous effect as well- the greenhouse gas effect. In one extreme Venus is boiling hot for example. without our CO2 in the atmosphere, Earth with be a frozen ball. Due to increases in CO2, the earth has been warming in the past 100 years.
