The study offers an updated calculation of the Earth's energy imbalance, the difference between the amount of solar energy absorbed by Earth's surface and the amount returned to space as heat.

Lead scientist James Hansen, a prominent NASA climatologist, described the findings on the planet's out-of-balance energy exchange as a "smoking gun" that should dispel doubts about forecasts of climate change. A European climate expert called it a valuable...
