Many recent past periods were warmer:

Liu Y, Cai Q F, Song H M, et al. Amplitudes, rates, periodicities and causes of temperature variations in the past 2485 years and future trends over the central-eastern Tibetan Plateau. Chinese Sci Bull, 2011, 56: 2986 2994, doi: 10.1007/s11434-011-4713-7 [ Climate Change over the Past Millennium in China.]

Steve Macintyre's comment on this paper: "To my knowledge, Loehle’s network is the first network to be constructed using series in which every proxy as input to the network has already been calibrated to temperature in a peer reviewed article. This is pretty amazing when you think about it. It’s actually breathtaking. Every prior network has included some, if not a majority, of uncalibrated proxies." http://climateaudit.org/2007/11/20/something-new-in-the-loehle-network/

Greenland temperature was warmer in the past:

Fig 1 of Kobashi, T., K. Kawamura, J. P. Severinghaus, J. M. Barnola, T. Nakaegawa, B. M. Vinther, S. J. Johnsen, and J. E. Box (2011),
High variability of Greenland surface temperature over the past 4000 years estimated from trapped air in an ice core, Geophys. Res. Lett., 38, L21501, doi:10.1029/2011GL049444. http://www.leif.org/EOS/2011GL049444.pdf

To claim CO2 is causing recent warming, you have to show why it warmed similarly in the past without CO2 and then why that explanation does not apply to modern warming.
