A new study says that global warming will impact fruit and nut tree productivity in Australia and globally. Most fruit and nut trees have evolved in cool temperate climates and go through a dormant winter phase and require a certain amount of winter chill to trigger their spring growth and fruit production. But with strong trends in many regions for warming winter minimum temperatures and reduced number of 'winter chill' days, the heat is on our orchards.
