Recent satellite data has revealed a significant shift in global vegetation patterns, with the 'green center' of the planet moving northeast over the past few decades. This shift indicates that the most intense seasonal plant growth is occurring in different locations than in the past. The study, published in the Proceedings of the National Academy of Sciences, highlights how these changes could impact agriculture, water demand, and wildlife migration. The movement of the 'green wave' is attributed to factors such as warmer winters and longer growing seasons, particularly in the Northern Hemisphere, which are altering the balance of global vegetation.
