Another study which predicts dire effects due to global warming/climate change. However it failed to mention how these predictions were made. I suspect that computer modelling was involved. To date, the success of these models has been very poor so any conclusions based on them must be taken with severe reservations. In other words, this is probably another study that should be left to gather dust.
Computer modelling is used in many areas of science/engineering with great success (I myself have been a computer modeller for over 30 years, so I understand many of the issues involved). However, climate modelling has not reached that level yet.
