Readers discuss net-zero carbon emissions and glass frogs

For good measure

Cutting carbon dioxide emissions to curb climate change and reach net-zero is possible but not easy, Alexandra Witze reported in “The road to net-zero” (SN: 1/28/23, p. 22).

A report by Princeton U­niversity’s Net-Zero America project, released in 2021, estimates that wind and solar power production needs to roughly quadruple by 2030 to achieve the United States’ goal of net-zero carbon emissions by 2050, Witze reported. In the most ambitious scenario, “wind turbines would cover an area the size of Arkansas, Iowa, Kansas, Missouri, Nebraska and O­klahoma combined,” she wrote.

Reader Mary Sweeney noted that, while technically correct, the statement quoted above could be misleading.
