Reconstructions of past Hothouse climates had shown that temperatures had been around six degrees higher on average, and higher still in polar regions, with no polar ice - caps and a temperate to subtropical fauna and flora, as evidenced by the fossil record in these areas.

More recent studies, with much more precise correlation between ice cores and global temperature records, have shown that temperature and CO2 changed synchronously in Antarctica during the end of the last ice age, and globally CO2 rose slightly before global temperatures.
