India and Pakistan have already fought several wars. Now both are nuclear armed. How can increasing food insecurity in this volatile region lead to a reduced risk of conflict. Access to wealthier nations for environmental refugees, including from increasingly flood-prone island states and coastal regions such as Bangladesh, will be limited. Most of the above possibilities are mentioned in the existing scientific literature, but hardly any were forecast a generation ago.
Climate change is far from our only environmental, economic and social problem.
A rump of contrarian climate scientists, rarely if ever published in the peer-reviewed literature, receive disproportionate coverage and weight. The favoured strategy has been to emphasise uncertainty, rather than totally denying risk. They are based on the conclusion that the risk of climate change is negligible. Battle, M., M.
