Differences between novel interactions originating from globalization compared with climate change.

	globalization	climate change
climate matching	new organisms that fit into a specific climate envelope	adaptation to slightly different conditions
host/competitors	new	changing
movement	along trading routes	along climatic gradients
coevolution	none	partial
range expansions	latitude and longitudinal	latitudinal (towards the poles)
main component	pathogen control	environmental control
overall risk	high–medium	medium–low
