First, Do No Harm (Addendum 2)

According to a recent NASA report, greenhouse gases, not the sun, are driving global climate change. According to the article,

A recent, prolonged lull in the sun’s activity did not prevent the Earth from absorbing more solar energy than it let escape back into space, a NASA analysis of the Earth’s recent energy budget indicates.

An imbalance like this drives global warming — since more energy is coming in than leaving — and, because it occurred during a period when the sun was emitting comparatively low levels of energy, the imbalance has implications for the cause of global warming.

The results confirm greenhouse gases produced by human activities are the most important driver of global climate change, according to the researchers.
