Tropical flowers are blooming months earlier or later than they used to because of climate breakdown, with potentially “cascading impacts across ecosystems”, according to a study of 8,000 plants dating back 200 years.

Researchers looked at flowers from a range of countries, including Brazil, Ecuador, Ghana and Thailand, home to the most biodiverse ecosystems on Earth, but also the most understudied.

The Brazilian amaranth tree flowers 80 days later than it did in the 1950s, while the Ghanaian rattlepod shrub’s flowering period shifted 17 days earlier between the 50s and 90s, according to a study of museum specimens.

It was previously thought that tropical regions – where temperatures fluctuate less over the course of the year – would not be so affected by the climate crisis in terms of the timing of flowering. This hypothesis has been proved wrong, said the lead researcher Skylar Graves from the University of Colorado Boulder, who added that “nowhere on Earth is unaffected by climate change”.
