Speakers said a two degree rise in temperatures would give Cornwall hottest days of 35 degrees C, while coastal erosion and flooding would increase due to a rise in sea levels and storm surges.
The panel said the UK Climate Change Act would place mandatory targets for emissions.
To limit global warming to two percent emissions must be limited. Currently they are increasing by three percent a year.
