http://climate.nasa.gov/climate_resources/24/ - it's happening and humans are doing it. Every major scientific foundation worldwide acknowledges it. All scientific data gathered from the onset of the discovery has added to it's merit. There are no longer any meritable debates on whether or not humans are causing it - they are now about how to fix it.
On one hand its sort of a marvel that humans as a race are now powerful enough to have global/planetary impact (aka terraforming) but on the other hand we are reverse terraforming on our current course slowly making the climate in general more volatile/less stable, and less suitable for non-co2 consumers.
Look at the thick atmosphere of Venus - loaded with co2 and significantly hotter than Mercury (which is closer to the sun) - same greenhouse effect slowly building up on Earth.
"The atmosphere of Venus is very thick and is about 90 times more massive than Earth's atmosphere. It is mostly carbon dioxide gas (about 96%), with some nitrogen (about 3%) and a very small amount of water vapor (0.003%). Venus also has a thick layer of sulfuric acid clouds."
In the end it won't matter whether humans in general are smart enough to understand the why/how of climate change or necessarily agree on what is causing it. In the end humans will work to re-stabilize Earth by reducing our bloated footprint or we won't.
Spoiler alert: we already are. Investments in solar/wind/renewable's in general have all skyrocketed in the past decade. Wind production in the US has already overtaken Coal.
