The UK Met Office climate change Google Earth layer showing regional warming in a 2C world.

1. 2C World
2C policy from EU 1996
formalized by 2009 Copenhagen Accord
2008 UK Met Office Google Earth
Climate Change Layer
The layer uses authoritative science from the UK's Met
Office Hadley Centre to show world temperatures
throughout the next hundred years under medium
projections of greenhouse gas emissions.

3. Arid and semi-arid regions
Arid and semi-arid climates comprise over one quarter of the land area of earth (more
than any other climate type).
Desert Meteorology, Thomas T. Warner, 2004, Cambridge University Press
Semi-arid regions represent a significant portion of earth's surface. More than three-
quarters of a billion people (more than one in eight) are estimated to live in dry lands.

4. Agriculture
Crop productivity is projected to increase slightly at mid - to high latitudes for local mean
temperature increases of up to 1.5-3.5 °C from pre-industrial depending on the crop, and then
decrease beyond that.
Global production potential, is threatened at +1.5 °C local temperature from pre-industrial
