Your article on rallies in support of refugees highlights the gap between widespread public sympathy and the current lack of humane co-ordinated EU or international action to deal with a crisis of such magnitude (Glasgow's brainchild: rallies held across the globe for refugees, News, September 13). The major issues which underlie this migration, religious warfare, exploitation, food security and wealth inequality will not be solved by political infighting at any level.

To the above list should be added the global impact of accelerating climate change. Comprehensive international agreement attempting to find a viable solution awaits the Paris conference in December. Failure to adopt radical measures on carbon reduction may invoke an even more serious migration problem. Is any commission or the UN capable of enforcement? Present disharmony on migration is not reassuring.

In case this sounds alarmist, fear not. Waiting in the wings until the going gets rough for the "comfort zone" is a vastly more dangerous strategy for tackling our wayward weather: geo-engineering. Branson and the big boys are already rubbing their hands. The Cameron/Osborne political game of fossil fuel versus renewable energy with natural gas as a solution to reducing CO2 emissions is kindergarten by comparison.
