题目内容
Global warming is a world problem and Monitoring (监制)it usually needs a lot of math knowledge. But Francisco and Ruby track(追踪) what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade.
“We are collecting data because the weather is changing and the plants are blooming (开花),” Ruby explained.
Many other students at Borton Primary Magnet School and Sunnyside High School in Tucson are going outdoors to be part of a new scientific action to figure out（计算）how the biological timing of the Earth is changing. It’s a research project that everyone, even a kindergartner, can join in.
The National Phenology（生物气候学）Network is calling on volunteers to help track early spring blooms and changes in animals caused by global warming. It’s called Project Budburst. When it was first open to the public last year, thousands of people joined in .
“Everyone can offer his hand by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard,” said Phenology Network director Jake Weltzin.
The idea is that tracking flowers blooming —— especially lilacs（丁香）which ordinary people have helped track for many years ——is simple. The Project Budburst website gives directions on what to look for in different parts of the country.
University of Maryland professor David said it was so easy to figure out what’s blooming that a lack of special knowledge wasn’t a problem.
