Holdridge life zones – Wikipedia. Excerpt.
Climate
change
Many areas
of the globe are expected to see substantial changes in their Holdridge life
zone type as the result of climate change, with more severe change resulting
in more remarkable shifts in a geologically rapid time span, leaving less time
for humans and biomes to adjust. If species fail to adapt to these changes, they
would ultimately go extinct: the scale of future change also determines the
extent of extinction risk from climate change. For humanity, this phenomenon has
particularly important implications for agriculture, as shifts in life zones happening
in a matter of decades inherently result in unstable weather conditions
compared to what that area had experienced throughout human history. Developed
regions may be able to adjust to that, but those with fewer resources are less
likely to do so.
