Answer:
Plants consuming less water / adapting to heat and drought.
Step-by-step explanation:
As we can already see, mostly in Europe, climate change (rise in temperatures) has had a drastic impact on the (mostly in summer) climate.*
Now, to the point. I am really sure that by the end of this summer, many plants will die, but some might also realise that less water is avaliable, and that temperatures are higher. This will cause a noticable change to a plants metablism and endurance (heat-wise), and we will surely be able to see it in probably 2-3 summers time.
*Keep in mind that the current heat affecting Europe is not only caused by global warming, it has been also affected by a heat-wave coming form northern Africa.
