Jurbane, which of the many super computer climate models have duplicated the past correctly? Which of the same models have made any correct predictions?
An Example:  SCIENTISTS were predicting an arctic free ice by 2013, changed to 2016, now 2020 or is it 2030, 2050, 2100?  However one of the significant problems with the SCIENTISTS is their failure to account for the MWP or LIA as they were global.  Climategate certainly proved that.
