Answer:
Short term climate changes are only temporary, they will come and go and they won't have a major effect on the ecosystem. Long term climate changes, on the other hand, are not as temporary, they either stay forever or long enough that we can say forever, and they have a huge effect on the ecosystem.
Explanation:
One example of a short term climate change is the seasons, it gets colder in the winter, but that is only a temporary change and even though the ecosystem changes, it is only small changes, and they are reversible.
One example of a long term climate change is the last ice age, it lasted a very long time, and had huge effects, like long-lasting frigid temperatures and frozen oceans, that had a huge effect on the ecosystem, which then took a very long time to expel.
