Roy Thompson from the department of Geology and Geophysics, Edinburgh University, told Tiasa Adhya that by 2080 certain plants would flower 50 days ahead of schedule because of climate change. As spring moves up the calendar it is bound to affect the birds that cannot change their migratory patterns as promptly
On the impact of global warming on flowering
Plants are sensitive to temperature and change their flowering patterns to adapt to climate change. Hence the first flowering date also changes. Using our study at the Royal Botanic Garden in Edinburgh, we calculated that for every 1C rise in temperature, spring flowering would begin 11 days earlier. For maritime climates, flowering would begin 16 days ahead of the start of spring and stop 12 days after spring ends.Under continental climates, further inland, flowering would begin seven days prior to spring, ending 11 days after it ends. So, by 2050, traditional Scottish spring flowers like buttercups, irises and geraniums would be available on Valentines Day, that is, before the winter ends.
