The Sun's heating effect on the Earth's surface has been carefully measured for many years. The data is included in climatologists analyses. It clearly shows the Sun is not steadily increasing. From the Source below:

More about why it's not the Sun:

"Study clears sun of global warming"

The swindle video is wrong.
"A Channel 4 documentary claimed that climate change was a conspiratorial lie. But an analysis of the evidence it used shows the film was riddled with distortions and errors."
http://news.independent.co.uk/environment/climate_change/article2355956.ece
"The science might be bunkum, the research discredited. But all that counts for Channel 4 is generating controversy."
http://environment.guardian.co.uk/climatechange/story/0,,2032572,00.html
All this and more is why the vast majority of scientists know that global warming is mostly (80-90%) man made.

1. Many scientist do not agree with *man caused* global warming.
2. None of the models that predict Global Warming include water vapor (clouds and such) in the modeling even though water vapor contributes 90% of the Green House Effect.
3. If you are *REALLY* interested in data from data from the other side the Birtish produced a documentery (The Great Global Warming Swindle) outlineing some of the *many* objections to Man Caused Global Warming. It aired on BBC Chanel 4 and can be seen on YouTube here: http://www.youtube.com/results?search_query=The+Great+Global+Warming+Swindle&search=
It will take about 90 min to view all 8 parts..... But if you are *REALLY* interested in facts instead of hype , watch this video.... you might actually learn something.

The scientists that say it is happening are getting government grants, the scientists that say its bollocks are getting threatened.
Cosmic rays create clouds. When the sun is active with solar storms, the storms repel the cosmic rays from us, which means we have little cloud coverage so the suns heat warms us. When the sun is calm, lots of cosmic rays get into our atmosphere and create major cloud coverage as we've recently seen in the Uk. The big low clouds are dark on the bottom but bright white on top, and the white tops reflect the suns heat back into space which cools us. Look up Maunder minimum in wikipedia.

Easy
A new study shows the Sun's radiation has increased by .05 percent per decade since the late 1970s.
The increase would only be significant to Earth's climate if it has been going on for a century or more, said study leader Richard Willson, a Columbia University researcher also affiliated with NASA's Goddard Institute for Space Studies.
If the solar out put has gone up for 100 years at .05 for every 10 years the solar heat we are getting has gone up by .5%.
The Global warming of the earth has only been shown to have gone up less than 1 degree in 100 years.
The Sun's increasing output has only been monitored with precision since satellite technology allowed necessary observations. Willson is not sure if the trend extends further back in time, but other studies suggest it does

One, proving a negative is very hard.:)
Two,
The crux of the problem seem to be the Earth has warmed a few degree in a century. Excuse me if I don't trust temperature readings from 1907. After getting the temperature, they went to crap in the out house and then had the doctor apply a leach to stop the headache.
BTW, climate change is on Pluto too, but I can't find the link. Do you think maybe the output of the sun in its sunspot cycle might be the culprit?:)

jmminc, I don't see what you prove with that?
"The combined anthropogenic RF is estimated to be +1.6 [-1.0, +0.8] W/m2, indicating that, since 1750, it is *extremely likely that humans have exerted a substantial warming influence on the climate. This RF estimate is *likely to be at least five times greater than that due to solar irridiance changes. For the period 1950 to 2005, it is *exceptionally unlikely that the combined natural RF (solar irridiance plus volcanic aerosol) has had a warming influence comparable
to that of the combined anthropogenic RF."
* Extremely likely: >95% probability.
* Likely: >66% probability.
* Exceptionally unlikely: <1% probability.
eric c: The temperatures has risen in the last decade.

Mid century cooling. If the mid century cooling was caused by sulphates, then you should expect to see a sharp increase in sulphates following WWII, but as this chart shows you do not. You see a decline. http://www.globalwarmingart.com/wiki/Image:Climate_Change_Attribution.png
What is more you see high levels of sulphates, low levels of co2 during the early part of the century, but temperatures rose.
Jan Veizer, professor in Canada was politically motivated to give an explanation for the mid century cooling. After studying many studies he concluded " that solar activity has been the “climate driver” for billions of years. While the climate can be affected by the many factors, it is the sun and its effects that have caused changes in climate for 4 billion years. Dr Veizer first set out to prove that CO2 was historically what caused changes in climate, but noted, “Personally, this last decade has been a trying period because of the years of internal struggle between what I wanted to believe and where the empirical record and its logic were leading me.”
Other also support his conclusions on solar variability
http://www.geocraft.com/WVFossils/Reference_Docs/The_Geologic_Record_and_Climate_Change.pdf
World wide temperatures have not risen in the past decade, which also goes against the co2 theory

I don't care about global warming, if it exists!! Don't much give a sh*t! I'll be dead and gone before it's a problem. I hate cold weather anyhow. My kids and grandkids will be dead and gone too. Far as I'm concerned it's not my problem. Bring on them greenhouse gasses!!!

It is never possible to prove a negative. Instead the possitive must be proved. Failure to prove the positive effectively stipulates the negative.

There is also the fact that we are still coming out of an ice age if you look at it on this planets life cycle. We ride a world that through millions of years heats up and then freezes over. oops didn't mean to get real deep into this.
