Climate change indicators
Computer modelling by world leading climate research centres enable us to predict the likely environmental consequences of climate change.
Climate research centres, such as the UK’s Met Office’s Hadley Centre and the Tyndall Centre for Climate Research predict the likely environmental consequences of increased average global temperatures exceeding what is widely regarded as the critical 2ºC level.
When a 3ºC global average increase is modelled we see major shifts in weather with extreme weather events such as storms, flooding and droughts predicted to become more frequent and severe.
The most important graph in the world.
Based on the UK Met office Hadley Centre’s coupled atmosphere-ocean general circulation model, this assumes that the atmospheric concentration of carbon dioxide more than doubles over the course of the 21st century. This 'business as usual' scenario assumes mid-range economic growth and no measures to reduce greenhouse-gas emissions.
