According to Ron Bailey at Reason.com
Stress - this is a rumor. However, the rumor says that next week Richard Muller will release the latest Berkeley Earth Surface Temperature analysis of surface temperature data going back as far as the 18th century. Muller, once skeptical of the temperature records that showed considerable global warming in recent decades, set up BEST to reanalyze that data.and
The rumors say that new BEST reanalysis will show that global average temperature has increased by 1.5 degrees Celsius since pre-industrial times and will suggest that most of the warming since the 1950s is the result of increased greenhouse gas concentrations in the atmosphere.
Watch out for the look over there act from the usual characters. The Pielkesphere is parsing furiously. Rumor has it that Tony Watts has gone into full lockdown mode, that Steve McIntyre has sold all his penny stock and will be flying back from England with the CRU server, but more importantly, Tuesday is the last day to have papers considered in the next IPCC report.
