On BBC Two tonight, Newsnight Science Editor Susan Watts will be examining claims by senior climate scientists that global warming is a “major contributing factor” (Dr Ghassem Asrar, director of the World Climate Research Program). As part of this Susan will be asking Met Office Chief Scientist, Prof Julia Slingo what role, if any, climate change has played in this disaster, whilst our forecasters at the BBC Weather Centre explain more behind the science of the monsoon and the developing La Nina.
