I'm talking about evidence from both proxy records in the last 50,000 years (if possible) and the recent past (if also possible)

  • $\begingroup$ The mechanisms that give rise to correlations between temperature and CO2 on long timescales (e.g. paleoclimate - temperature driven ocean degassing?) and shorter timescales (e.g. the instrumental record - variations in vegetation in the Americas resulting from ENSO?) are unlikely to be the same. Also I don't know whether there are any suitable ocean temperature proxy records. It would be helpful if you could give some more information about what inspired the question. $\endgroup$ Jun 26 '14 at 11:57
