Question

the students further wondered if humans had an impact on the disappearance of lake chad. they used the model below to help answer their clarifying questions. figure 3 predicted global temperature increases based on fossil fuel burning projected temperature increase (°c) 14 how does figure 3 help students ask questions about future changes in lake chad? it proves that co₂ emissions have no impact on water resources it suggests that continued co₂ emissions may lead to even higher temperatures, affecting water availability it predicts that lake chad will completely dry up by 2050 it shows that lake chads water levels will stabilize due to decreased fossil fuel burning five scenarios of fossil fuel burning highest co₂ amounts medium to high co₂ amounts medium co₂ amounts smaller co₂ amounts, then no increase in co₂ late in the 21st century no increase in co₂ beginning in 2060

Explanation:

The figure shows projected temperature increases based on different levels of fossil - fuel burning. Higher temperatures can affect water availability. Continued high CO₂ emissions (linked to fossil - fuel burning) in the figure may lead to higher temperatures which can impact Lake Chad's water resources. It doesn't prove CO₂ has no impact, predict Lake Chad will dry up by 2050, or show water levels will stabilize due to decreased fossil - fuel burning.

Answer:

It suggests that continued CO₂ emissions may lead to even higher temperatures, affecting water availability.
