What is the percent of what we contribute to global warming?

I am in an debate at school over if humans are a contributer to global warming and i need some help..please....anything that helps me say that humans are a contributer to global warming...THANKS☺
 
Well lets see Co2 was .0287% of all earth atmospheres and now it has increased to 0.030% or almost anyway what about .013% in crease in Co2, Wow that will kill you. Many scientist believe that Co2 follows the humidity level instead of heat following the Co2 level.
Then their is the sun spot theory - I tend to go with this being how the Ice caps on Mars are also melting as ours are.
Anyway here are two good links to inform you on this. Good Luck
 
CO2 levels have been much higher in the past then they are now. It has also been suggested that CO2 levels increase after warming, not before.
 
Their computer models are all that predict any harmful warming. I wouldn't be too worried about that because they don't reflect the real world very well just fyi. Most likely the sensitivity to CO2 warming is less than the computer models assume. The world has been warming for 300 years but for some reason the alarmists want to attribute all of the warming of the last century to humans. The reason is actually obvious. They only get power and money if this is a crisis and they can blame humans. Its politics. To answer your question, the climate is too complex to know for sure.

This guy answered it.. Translated, that means we contributed about a 1/3 of the increase in the last centurry or less than a quarter of a degree. That isn't taken very well in the alarmist community where the better the news is for the world the worse it is for them and that is not enough to worry about.

"...Professor Lindzen comments that this failure of observation to match prediction cannot be so easily explained, since the transient response would be likely to exceed the equilibrium response. He concludes that no more than about a third of the observed trend at the surface is likely to be due to greenhouse warming, and adds: “This is about as close as one ever gets to proof in climate physics."

No doubt about it,
the raise in carbon levels on earth since the industrial revolution have gone up tremendously. (This is a big factor of the reason for global warming.)
Its be cause of all the amount of energy we use now.. we are far from being able to reverse the damage done from it. all we can do is try to use cleaner energy production and hope it steadys out.

Also, I know alot of people say that the earth goes in cycles, it warms and then cools itself. But we're able to look back through time and see how high the carbon levels have been in the past. NEVER at any time in our known history has carbon levels been as high as they are now. It is not a coinsidece that it happens to be around the same time we discovered the combustion engine.. and now look at all the things we have created. they all need energy anything that uses energy somehow is related to release of carbon emissions. Only now are we creating ways to lower that.
