The phenomenon of brilliant red and gold autumn foliage might change due to the large amount of carbon dioxide we put in the atmosphere, and the resulting warmth that carbon traps inside.

The higher concentration of carbon dioxide itself might actually make fall colors brighter, Howard Neufeld, a professor of physiological plant ecology at Appalachian State University, explains in a Tuesday piece in The Conversation, citing research published in the journal New Phytologist back in 2010. But the higher temperatures that result from large atmospheric concentrations of carbon dioxide could result in longer summers and shorter autumns, thereby delaying the onset of future colorful leaf seasons and causing them to be shorter in duration.
