IPCC’s fourth assessment report concludes that climate system warming is unequivocal, and a fall in green house gas emissions is necessary in order to stabilise the concentration of green house gases in the atmosphere and avoid irreversible environmental damage.
According to IPCC's case scenario, the concentration of CO2-equivalents can be stabilised at 445-490 ppm if green house gas emission peak before 2015, and global GHG emissions are reduced by 50-85% in 2050 compared to 2000.
It is estimated that this best case scenario will bring a global temperature change of about 1.8º Celsius. To carry through a global reduction in the emissions of GHG not later than 2015 is a huge task, however, the consequences of letting things slide are unpredictable and immense.
A rise in temperatures of 2º Celsius may bring 30% of all species at increased risk of extinction. If temperatures rise even further, to 3.5º Celsius, model projections suggest significant extinctions of 40-70% of global species.
Consequently, the goal of the project is to demonstrate climate solutions and plans that can contribute toward the IPCC's 2º Celsius scenario.
