Front

If you took away the atmosphere’s natural greenhouse effect, and everything else stayed the same, Earth’s temperature would be?

Back

50-60°F cooler

Front

How do scientists collect evidence about climate? Options: using remote sensing from space with satellites, by ground-based measurements of surface temperatures, carbon dioxide concentration and sea level, by collecting “proxy data” from tree rings, ice cores, and historical records

Back

all of the above

Front

Compared to other greenhouse gases, carbon dioxide is the most effective in trapping heat near the surface of the Earth.

Back

true

Answer explanation

True. Carbon dioxide (CO2) is the most significant greenhouse gas for heat retention, effectively trapping heat in the Earth's atmosphere, more so than other greenhouse gases.
