International Climate/Hardiness Zones

[emk]

Is there an international system of measuring climate / hardiness requirements other than the USDA zones we use here in the US? I'm looking for a way to check the climate zones in Asia, Europe, Australia, etc. and as far as I know the USDA only provides a map/zone listing for North America.
