claim: That model predicted that global temperature between 1988 and 1997 would rise by 0.45°C (Figure 1).
evidence: As with Uranus, the source of this heating is unknown, but the discrepancy is larger: Uranus only radiates 1.1 times as much energy as it receives from the Sun; whereas Neptune radiates about 2.61 times as much energy as it receives from the Sun.
