The Washington Post has further leaks from the IPCC's Fifth Assessment Report. They can be seen here.
The conclusions about the millennial temperature reconstructions...
The 30 years from 1983-2012 was very likely the warmest 30-year period of the last 800 years.
are interesting when compared to what was said last time round:
Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1,300 years.
The shift from 50-year periods to 30 years periods makes direct comparison difficult, but this does seem to suggest something of a reining back. The Medieval Warm Period, located by AR4 in the centuries spanning the end of the first millennium, is now apparently accepted as probably being warmer than the current warming, at least if the Washington Post is to be believed.
