Changing temperatures and climate affects flowering and maturity of crops and other plants.
(2013) Smithsonian magazine. Since the beginning of the 20th century, the growing season in many areas of the lower 48 states has expanded by about two weeks. Frosts end earlier in the spring and begin later in the fall. To gardeners in Maine, Wisconsin and Montana, that might seem a blessing. What’s not to like about more lettuce or riper tomatoes? The longer seasons, however, are also helping invasive plants annex American soil; extended springs mean they can more quickly push aside native species and transform ecosystems. “What’s interesting about climate change is that humans are effectively manipulating how species experience time,” says ecologist Elizabeth Wolkovich of the Biodiversity Research Centre at the University of British Columbia.
