The CO 2 seasonal cycle amplitude (SCA) in the Northern Hemisphere has increased since the 1960s-a feature attributed mainly to enhanced vegetation activity along climate warming and CO 2 increase. We identified a temporal change in the sign of the correlation between SCA and air temperature (T) from positive to negative around the year 2000 at...

While climate warming reduces the occurrence of frost events, the warming-induced lengthening of the growing season of plants in the Northern Hemisphere may actually induce more frequent frost days during the growing season (GSFDs, days with minimum temperature < 0 °C). Direct evidence of this hypothesis, however, is limited. Here we...
