Alpine shows excellent proof he doesn't know what Scenario B is with his reply:
i already told you ^^^^ there...
you are incapable of reading and understanding...
He stated this as what he thinks Scenario B is:
it is a linear increase scenario, which is what it was in reality...
I gave this broken head a link to the source he obviously never read what Dr. Hansen wrote, he made this revealing reply at post 83, showing his abject ignorance in what Scenario B is:
"it is accurate enough for a study done 30 years ago...
it demonstrated the type of increase we should expect in a linear co2 emission increase quite well...
i also showed you how well it fits in once you adjust the model with the knowledge which he didnt have 30 years ago and had to assume...
the stupidity in your copy/paste post that expects to prove anything to anyone by bashing an unlikely scenario in a 30 year old study stands however... "
bolding mine to show what this fool says about CO2 emissions, he states that CO2 emission increases from 1988.
Now here is what Dr. Hansen actually stated for Scenario B
"ORIGINAL CAPTION: Fig. 3. Annual mean global surface air temperature computed for trace gas scenarios A, B, and C described in reference 1. [Scenario A assumes continued growth rates of trace gas emissions typical of the past 20 years, i.e., about 1.5% yr^-1 emission growth; scenario B has emission rates approximately fixed at current rates; scenario C drastically reduces trace gas emissions between 1990 and 2000.] The shaded range is an estimate of global temperature during the peak of the current and previous interglacial periods, about 6,000 and 120,000 years before present, respectively. The zero point for observations is the 1951-1980 mean (reference 6); the zero point for the model is the control run mean. "
Scenario B is about CO2 emission at fixed current rate for 1988, but the post one article shows it has increased a lot since 1988, as I showed at

Scenario B is obviously wrong, CO2 emissions have
gone up since 1988 while his scenario B is CO2 stays at 1988 rate (no increase at all).
Scenario A allows for increasing CO2 emissions from 1988 onwards.
Dr. Hansen wrote,
"1. [Scenario A assumes continued growth rates of trace gas emissions typical of the past 20 years, i.e., about 1.5% yr^-1 emission growth; "
bolding mine
It was actually 1.9%/yr but close enough, but his predicted temperature trend based on this scenario A was way off, as shown here:

You have been smashed, I am done here showing how ignorant and stupid you are.
