Play an AI-generated podcast conversation about this lesson

What is the direct effect of climate change on agriculture according to the text?

Increase in water and environmental resources

Increase in frequency and magnitude of extreme climatic events

Increase in food and forestry production

Effect due to temperature change and CO2 level (correct)

How does climate change affect crop yields in mid- to high-latitude regions according to the text?

Moderate warming benefits crop and pasture yields (correct)

Slight warming decreases yields in seasonally dry and low-latitude regions

Crop yields decrease due to the increase in extreme climatic events

Crop yields are unaffected by climate change in these regions

What is the impact of climate change on the number of people at risk of hunger according to the text?

Climate change will lead to a significant increase in the number of people at risk of hunger

The marginal increase in the number of people at risk of hunger due to climate change must be viewed within the overall large reductions due to socio-economic development (correct)

Climate change will have no impact on the number of people at risk of hunger

The impact of climate change on the number of people at risk of hunger is uncertain
