Final answer:
The strongest predictor of how likely a nation is to support climate change action is the level of public awareness and belief in the reality and urgency of climate change.
Step-by-step explanation:
The strongest predictor of how likely a nation is to support climate change action is the level of public awareness and belief in the reality and urgency of climate change. Research shows that countries where a higher percentage of citizens believe in climate change and perceive it as a threat are more likely to support climate change action. For example, in the United States, the support for climate change action is influenced by factors such as age demographics, severity of weather events, and visibility of green energy sources like wind power and electric cars. However, there are also deep divisions within countries, with some opposing clean energy producers and punitive methods to control emissions.
