Which outcome arises when significant ashfall buries boreal forests?

💡 Explanation

Increased albedo occurs due to ash deposition obscuring vegetation; this is because the albedo effect involves increased reflection of solar radiation back intospace. Therefore, cooling occurs, rather than increased wildfires from tephra acting as fuel.
