The popular idea of cutting our emissions in half in 10 years only gives us a 50 % chance of staying below 1.5 degrees, and the risk of setting off irreversible chain reactions beyond human control.
A reversible reaction is a reaction where the reactants form products, which react together to give the reactants back.
A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from reversible process in thermodynamics.
