Tempreture rises higher than 7 F degrees were the pessimistic least conservative estimates of the time.

Lower tempreture rises were conservative estimates based on "preserving the current levels of CO2" emissions.

I am indeed one of the "another person"s that mentioned these are F units.

Nah, a more optimistic prediction would already be "-2 to 5" degrees.

"Conservative" in this context relates to the method, not the outcome. You're still ignoring the range-characteristic of the outcome and talk like it was "5-7" degrees.
