"A marine biologist and lead author of the research, Maria Byrne, said Sydney Harbour could experience extreme temperature and pH conditions, such as those used in the experiments, by 2070 to 2100."
Could be as soon as 60 years (2010/11 to 2070). You don't care what happens in 60 years, (give or take scientific uncertainty, so it could even be sooner) Technicals?
