Just like a sunrise, the emergence of leaves in spring is one of nature’s poetic, awe-inspiring moments. It reminds us of the phases of nature, inexorable and punctual. However, that punctuality is being influenced by climate change, which is causing plants to come into leaf earlier and earlier each year. That, in turn, has consequences for trees, as well as global effects on the carbon cycle and climate change itself.
In a situation of global warming, phenology becomes essential scientific knowledge to understand the environment’s behaviour in the medium and long term. Beyond changes as ephemeral and visible as the evolution of the colour of tree leaves, phenology studies the relationship between the cycles of living beings and the climate, linked to the annual course of meteorology in a specific place.
Wind dynamics need to be factored into studies that measure the impact of climate change on the rhythms of nature. A study published in PNAS and co-authored by CREAF-based CSIC researcher Josep Peñuelas concludes that a decline in winds is currently benefiting plant productivity.
