I know that you understand the topic, but a difficulty with discussion in this area is ambiguity in the language we use to describe it.

"CO2 reduction" might plausibly be read as (1) reducing CO2 concentration, or (2) reducing emissions, or even (3) reducing projected increases in emissions. These are very different, with (1) outside the range usually considered possible, (2) very challenging, and (3) feasible, but not well defined.

"Solving global warming increase" might plausibly be read as (a) reducing temperature, or (b) preventing further increases, or (c) keeping increases within some bounds considered acceptable. These are also very different. Accomplishing (a) would require (1) or a cooling fix, while (c) could be accomplished by (3) transitioning to (2). The standard of acceptability to be used in (c), however, is a matter of opinion, and the requirements for achieving any particular standard are uncertain.

Meaning (3) reminds of political games with budgets, where a "budget [or tax] cut" is actually an increase, but lower than a larger increase that someone had "projected".

Are there better terms we could use that would be short, yet make the distinctions clear?
