Climate change study sea level rise prediction is not going to worry anyone

A new climate change study has concluded that global warming of 3°C (5.4°F) - which is about what we are currently on target for, despite the Paris climate agreement target of 1.5°C - 2°C - could lead to a "catastrophic" sea level rise of 0.2 inches per year 2060, as the Antarctic ice fields melt.

Which made me stop and think: "catastrophic"? 0.2 inches (about half a centimetre, if you prefer) is about half the thickness of the cellphone I am currently holding. It's really not a lot. Yes, I understand that this is each year and the effect is cumulative, and I understand that there are potential positive feeedback loops involved here. But, even so, it's a little hard to get excited about 0.2 inches. After all, tides vary by up to several METRES each day (as do rivers each year).

Now, don't get me wrong, I do have plenty of faith in climate scientists who are trying to lead us through this potentially ruinous climate trajectory we are on (for what it's worth, this report comes from the Earth System Science and Policy Lab at Rutgers University, and I have no reason to suspect that this is a dubious outfit), and if they say it is catastrophic then I have to believe them. 

But I can't help but think that it may have been better to keep quiet about this particular conclusion. It sounds so underwhelming to the average Joe in the street that it can only serve to make people even more complacent.
