Dr. Ralph Kahn: "Separating causality from coincidence can be the linchpin of understanding, and at times can help identify prerogatives or highlight the path toward the better options. Yet making this distinction is frequently a challenge for me, and I think often for others as well, especially those of us currently engaged in studying and explaining aspects of Earth’s climate system. At an early age, I found that data can help address this challenge, providing evidence one way or the other — sometimes. I will share experiences, professional and personal, and at the intersection of the two, where the difference seemed to matter. In some cases the data offered at least a partial resolution. In others, not so much."
