Actually it's closer to 0.8C. The warming trend over the 20th century has been complied by multiple scientific bodies from the surface record:
Data @ NASA GISS: GISS Surface Temperature Analysis: Graphs
NCDC: Global Surface Temperature Anomalies
Temperature data (HadCRUT3 and CRUTEM3)

The reason I ask is that I have actually seen advocates of the global warming hoax point to ice core samples as their "evidence" of the mythical "global warming"!

I have seen people say that too. But I have never done that, and I have never seen any climate scientists say that either.
The ice core records show co2 rising 100ppm from glacial to interglacial periods, and this rise starts after the temperature starts rising, and takes many thousands of years. The warmings out of glacial periods are not primarily caused by co2.
