How do we expect climate to evolve in the future?
'If society continues to rely on fossil fuels to the extent that it is currently doing, then carbon dioxide (CO2) concentrations in the atmosphere are expected to double from pre-industrial values by about 2050, and triple by about 2100. This ‘high emissions’ pathway for CO2, coupled with rises in the other greenhouse gases, would be expected to result in a global average warming of around 4.5°C by 2100, but possibly as low as 3°C or as high as 6°C' >
