Aggregate demand and supply in us history

In the following four questions, use the aggregate demand and aggregate supply moded to describe the economic effects of each event/scenario described below. You will NOT draw a graph, but it will explain what happens in words. ( Hint: you can use your scratch paper to draw the graph if that helps with your explanation.)

Explain briefly the following:

1. What caused the change? (what non-price determinant of demand or supply changed? For example, income increased, costs of production decreased, etc.)

2. What happened to AD or AS? (increase, decrease, or unchanged)

- (Hint: to simplify your analysis, assume only one curve is shiting either Aggregate Demand or Aggregate Supply only.)

3. What was the effect on Real GDP and the Price-level (increase, decrease, or unchanged)

(2020) A United Nations report predicts that worsening global climate change will reduce production in agriculture and aquaculture (fishing) worldwide.
