during the last
interglacial), but the speed at which that might
happen is highly uncertain, though the other story this week shows it is ongoing.
--- What is of concern is what

interglacials.
Because the observed and predicted rate of increase in greenhouse gas concentrations and global warming is faster than seems to have
happened during the Last

The program also mentioned another fact that is almost always ignored by global warming catastrophists:
during the last
interglacial 125,000 years ago, called the Eemian, the Arctic also melted pretty much completely, as may be
