About
Historical climate datasets come from Chris Daly (Oregon State
University) using PRISM (www.prism.oregonstate.org). Projections of
future climate were created using a climatology created with historical
PRISM data and anomalies from 3 general circulation models and 3
emission scenarios.
Emission scenarios cover a wide range of the main demographic, economic,
and technological driving forces of green house gases (GHG) and sulphur
emissions.The A2 scenario corresponds to 1250 ppm CO2 eq, 15.1 billion
people on the planet, 53% of the primary energy source being coal,
resulting in a global warming of 2.0-5.4 deg. C by 2100. The A1B
scenario corresponds to 800 ppm CO2 eq, 7.1 billion people on the
planet, 4% of the primary energy source being coal, resulting in a
global warming of 1.7-4.4 deg. C by 2100. The B2 scenario corresponds
to 600 ppm CO2 eq, 7 billion people on the planet, 8% of the primary
energy source being coal, resulting in a global warming of 1.1-2.9 deg.
C by 2100.
The climate models used to calculate anomalies are from the Hadley
Center for Climate Prediction in the UK (Hadley), the Commonwealth
Scientific and Industrial Research Organization in Australia (CSIRO Mark
3.0), and Japan (MIROC or Model for Interdisciplinary Research on
Climate medium-resolution version 3.2).
