Why isn't a TCR type
of simulation, but instead using actual history and 200 year projected GHG levels in the atmosphere, that would produce results similar to a TCR simulation (at least for the AGW temp increase that would occur when the CO2 level is doubled) and would result in much less uncertainty than ECS (as assessed by climate
model dispersions), a more appropriate metric for a 300 year forecast, since it takes the climate more than 1000 years to equilibrate to the
hypothesized ECS value, and we have only uncertain methods to check the computed ECS value with actual physical data?
The «pause», should it continue, will discredit every
