For most of the holoscene, human civilization has developed during an interglacial period with periodic rises and dips in temperature that often mirror the same things we have seen in the past 2000 years.
The rise in industrial emissions and the resulting correlation of a change of a few degrees could simply be coinciding with a period of change in solar output or solar activity or other geological or meteorological phenomenon that is not as easily charted and graphed for the masses to consume.
Prior to the 20th century, the earth was in a little-ice age since the 16th century. Prior to that was the Medieval warming period in which temperatures could be interpreted to coincide with the warmer temperatures we have now.
If you want to post data causating emissions with climate change, please use a longer scale than 2000. About 60 million years is more appropriate as the Paleocene was the start of modern fauna which confer the greatest effect upon the carbon chemistry in our atmosphere.
If you do that, you'll find that there have been countless significant rises and falls in global temperature, often just as rapid, over thousands and millions of years without humans even existing on this planet to create carbon emissions.
Anyone that says that a global temperature increase of 0.6 is so totally transparent and 100% caused by man needs to read more than one book.
Look, I can post graphs too which show something remarkable with large emotional response! I will not however, claim that this is a definite proof with 100% scientific accuracy to predict our future.

You want evidence? Sure
Here we go.
This is the earth's ozone layer from 1979 to 2010 viewed from the south pole

and from the north pole

The blue is the deterioration of the ozone layer, and the growing deterioration is in DIRECT correlation with spiking omissions, all which break down the element O3, which is ozone.
This is what the global climate change is predicted to be in the next 60-90 years

Meaning that all that ice in the arctic will melt causing mass flooding and the deaths of millions of ecosystems.
I have taken my geology classes, I know all about the changing global temperature from the Hadean age to the Phanerozoic. The kicker is that the Ozone layer wasn't disintegrating during any other age but the Hadean, and that's because it didn't exist yet.
Having this much variation in this short of time is not natural and people need to pull their heads out of their asses and realize it.
