Cherry blossoms and sugar maple trees are primarily affected by earlier spring temperatures due to climate change. Both species rely on specific temperature cues for their blooming and leafing processes. As global temperatures rise, spring arrives earlier, which can disrupt their growth cycles and affect their reproductive success.
While both types of trees can be influenced by increased carbon dioxide levels (not oxygen), increased wildfire frequency, and the effects of melting polar ice primarily impact ecosystems rather than the trees directly, the most direct commonality in response to climate change for both is the shift in seasonal timing. Therefore, they are affected by earlier spring more.
