Question

The northward expansion of pine beetle habitats due to climate change is a significant concern because it leads to widespread tree mortality, alters forest ecosystems, increases wildfire risk, and potentially releases stored carbon into the atmosphere, exacerbating climate change.

In simple terms

Answer 1

The northward spread of pine beetles because of climate change is a big worry. It kills a lot of trees, changes how forests work, raises the chance of wildfires, and could release carbon that is stored in trees into the air, making climate change worse.
