Time required to accumulate the thermal time (°Cd) in the optimistic (SSP1-2.6 W/m2) and pessimistic (SSP5-8.5 W/m2) scenarios for the month of May in the current scenario and in different climate models. (a) Time required to accumulate the thermal time for the month of May in the optimistic scenario (SSP1-2.6 W/m2) for the near future (year 2050), for the current scenario, and in different models. (b) Time required to accumulate the thermal time for the month of May for the pessimistic scenario (SSP5-8.5 W/m2) for the near future (year 2050). (c) Time required to accumulate the thermal time for the month of May, in the optimistic scenario (SSP1-2.6 W/m2), for the distant future (year 2090). (d) Time required to accumulate the thermal time for the month of May in the pessimistic scenario (SSP5-8.5 W/m2) for the distant future (year 2090).
