There are impacts to the natural world, from climate change.
Warming a planet means shifting the climate zones of the planet.
And this is already observed to have happened.
In this animation from the Arbor Day Foundation, you can see
the hardiness zones have migrated northwards just in the last few decades.
If you're going to move these climate zones,
it's not so easy to move a forest.
This forest may suddenly find itself
in unfamiliar climate territory to which it's not suited.
And that could leave it vulnerable to collapse,
or encroachment, or fire.
Other aspects of the biota can
move quickly, such as insects can move basically instantaneously.
In the US, a
particular kind of insect called the pine bark beetle
is encroaching into the Rocky Mountain states.
It used to be kept in check by cold
temperatures in the winter, but
things have been so warm that the bugs are killing
vast stretches of forest in the Rockies.
Climate zones on mountains move to higher Elevations.
The rain forest in Australia and Queensland,
is located in the mountaintops,
climate zones which will disappear as climate changes.
These are the species and ecosystems that get hurt the most.
The ones that are basically chased
off the map by the changing climate zones.
Another example of that, is in the High Latitudes,
Where we're losing
the sea ice that supported the Polar bears.
The polar bears require sea ice as part of their life cycle,
and when the ice is gone, there's no place for them to go.
