As if there are websites without bias. Please try a better argument. That one is completely meaningless.
The people who are stating it have agenda's. Don't think for a moment that Al Gore doesn't have a vested interest in promoting man made global climate change.
You've convieniently placed yourself on both sides of the point in the same post. Congrats.
The CO2 properties are well known, in a laboratory. However, the are not well known in a complex non-linear climate system.
CO2 is a greenhouse gas. This is well known.
mankind is emitting CO2 at very high levels (which is less than .1% of the total carbon cycle of the planet)
I'm not sure of the .1% statistic, will have to look that up. Also not sure what you mean by bringing it up. But, I do know that the only a fraction of CO2 emissions from fossil fuels shows up in the atmosphere as gaseous CO2. The rest is absorbed by the carbon cycle. Meaning the earth already is absorbing what it can and the cycle is out-of-whack. Causing the problem.
Your first link was hilarious. He describes the 0.21 degree increase from 1930's to now as "minor". Using the Dust Bowl 1930's as the benchmark condition we are already warmer than is comedy at its finest. The rest seems to prove the sun makes the earth warmer. I discover this everyday when the sun comes up, evidently that's news to him. Most sources say that average solar activity has increased somewhat during the last half century but that increase only accounts for 20% (more or less depending on the source and my memory) of observed warming.
It also follows if the Sun is in fact causing warming, then the coincidental CO2 increase will make the Sun caused warming worse! Now that is alarming.
The other link appears to be a paranoid "they don't want us to know the truth, darn them" link in a long list of similar sites. You're not one of those 9/11 conspiricists are you? Reading paranoid people does not make you informed, it makes you paranoid.
Believe it or not, I use the denier sites quite often as a starting point when learning about this. I've found them mostly amateurish and paranoid, rather than enlightening. I also don't much care for Al Gore and haven't seen Inconvenient Truth. I don't think scaring people is the way to build consensus, and in fact leads to reactionary people getting the upper hand.
