The ‘Fruitful’ Results of Increasing CO₂ Despite the taboo, rising CO₂ and warming temps have helped fruit crops flourish—boosting yields, nutrition, and resilience from North Carolina to outer space. By Vijay Jayaraj

Among the climatically correct, nothing is more scandalous than describing carbon dioxide (CO₂) emissions as beneficial. You can be blacklisted from public forums and professional networking sites and even be removed from your tenured university position as an accomplished scientist.

Nonetheless, the truth is this: CO₂ is fundamental to the photosynthetic process by which plants make food for themselves—and ultimately for us. Furthermore, the increase in atmospheric CO₂ from industrial activity in the past century has helped vegetation over most of the planet to flourish. Also benefiting plants has been the relative warmth of recent decades.

Among the beneficiaries are fruit plants, whose sensitivity to cold is well established. In April 2007, an unseasonable freeze caused considerable low-temperature injury to small fruit plants, including grapes, strawberries, blueberries, and blackberries, in 21 U.S. states. The financial repercussions for the agricultural sector were substantial. In North Carolina alone, farming losses were estimated to be $112 million, including $86 million in damages to fruit crops.

During the Little Ice Age (1300–1850), many of the fruit crops faced significant challenges from low temperatures, shorter growing seasons, and extreme weather events like frosts, heavy rains, and drought.

In Iceland and high alpine areas, agriculture nearly collapsed. In China’s Jiangxi Province, centuries-old orange cultivation was abandoned due to cold. In temperate zones, apple and pear trees struggled with erratic temperatures, causing irregular blooming and lower yields.

Fast forward 175 years or so, and we have fruit crops thriving globally, thanks to elevated CO₂ levels, relative warmth, and a series of innovations in plant biotechnology. Regardless of whether certain politicians or news media believe it or not, plants love the warmer temperatures and increasing carbon dioxide of our season of plenty.

Rising temperatures extend growing seasons by delaying fall frosts and advancing spring thaws, allowing more plantings and reducing late-spring frost risks for orchard growers. The U.S. growing season has lengthened by over two weeks since the early 20th century.

A 2022 study led scientists to conclude that there is no doubt about the “fertilization effect of CO₂” on fruit species, which also benefit from natural warming as Earth recovers from the Little Ice Age.
