20、One of the best parts of autumn is its beautiful colors. Normally green leaves turn into red, orange, yellow, and finally brown. This is called "leaf phenology (生物气候学)", and many people look forward to it every year. However, due to climate change, autumn is changing.
According to a study published earlier this year in a journal, the season length is growing, meaning that it is taking longer for leaves to change their colors. And this is not the only way that climate change is ruining the season.
"Trees are holding onto their leaves longer," explained Dr. Howard Diamond, a senior climate scientist. "In my own neighborhood, I can remember that the leaves would drop a lot sooner 20 years ago than they do now. This is a personal observation, but research actually supports this phenomenon (现象) we're witnessing."
Climate change isn't just causing the leaves to change later. We can also expect later frosts (霜) according to Dr. Michael E. Mann, a professor of the University of Pennsylvania. Mann said, "That means mosquitoes and pests (害虫) remain active for a longer time in autumn, posing a greater health risk to human beings."
If there is any good news at all, though, we may be able to stave off this development. Mann pointed out that if humans reduce their carbon dioxide emissions (排放), they can still prevent the worst effects of climate change from affecting them during the autumn months. "A new study recently provides further evidence that surface warming will likely stop after carbon emissions reach zero," Mann stated in his recent comment for Live Science.
