Anyone know of better GW projections from 1988 period?
In 1988, James Hansen and team at NASA made projections regarding how much the 5-year running mean "global surface air temperature" would increase in the future under certain CO2 emissions scenarios. Their Scenario B seems close, considering the many variables and unpredictables (like volcanoes) over 20+ years. These projections clearly aren't exact; but, does anyone have clear documentation of any *better projections made at that time?
