As climate action finally begins in the United States in earnest, leaders face a maze of choices. The data keep coming in, and shifting, and sometimes changing. An example: methane is 21 times more impactful than carbon dioxide, per our EPA. Yet other credible and science-based entities state it’s 67 times more impactful, or 89 times. The fact that methane does not sustain in our atmosphere the same length of time as carbon dioxide does complicate quantifying its impact. We long for the day we can rely on data based on factual, empirical, nonpolitical science.
