Citizen Scientists

　　Understanding how nature responds to climate change will require monitoring key life cycle event—flowering, the appearance of leaves, the first frog calls of the spring—all around the world. But ecologists can’t be __51__ so they’re turning to non-scientists, sometimes called citizen scientists, for help.

　　Climate scientists are not present everywhere. __52__ there are so many places in the world and not enough scientists to observe all of them, they’re asking for your help in __53__ signs of climate change across the world. The citizen scientist movement encourages __54__ people to observe a very specific research interest — birds, trees, flowers budding, etc. — and send their observations __55__ a giant database to be observed by professional scientists. This helps a small number of scientists track a __56__ amount of data that they would never be able to gather on their own. __57__ like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready for the conditions where they live. __58__ that’s needed to become one is a few minutes each day or each week to gather data and __59__ it in.

　　A group of scientists and educators launched an organization last year __60__ the National Phenology Network. “Phenology” is what scientists call the study of the timing of events in nature.

　　One of the group’s first efforts relies on scientists and non-scientists __61__ to collect data about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle __62__ on a variety of common plants from across the United States. People participating in the project—which is __63__ to everyone—record their observations on the Project BudBurst website.

　　“People don’t __64__ to be plant experts -they just have to look around and see what’s in their neighborhood,” says Jennifer Schwartz, an education consultant with the project. “ As we collect this data, we’ll be able to make an estimate of __65__ plants and communities of plants and animals will respond as the climate changes. ”
