On Sept. 22 and 23, the United Nations will host separate daylong conferences on two issues of incalculable importance to the future of humanity: population and climate change. Though the two meetings will take place just one day apart, neither is likely to refer to the other. And that will be a missed opportunity, because scientific research increasingly affirms that the two issues are linked in many ways.

The population gathering in the General Assembly on Sept. 22 will mark the 20th anniversary of the landmark International Conference on Population and Development held in Cairo in 1994. The next day’s summit has been convened by U.N. Secretary-General Ban Ki-moon for government and business leaders to brainstorm ideas for addressing climate change.

The coincidence of these meetings occurring a day apart offers a teachable moment for the global decision-makers gathering in New York. Actions to promote the well-being of women might produce mutually reinforcing benefits in both areas.
