Citizen Scientists

Understanding how nature responds to climate change will require monitoring key life cycle events一
flowering,the appearance of leaves and the first frog calls of the spring一all around the world.But ecologists
can't be everywhere so they're turning to non-scientists,sometimes called citizen scientists,for help.
Climate scientists are not present everywhere.Because there are so many places in the world and not
enough scientists to observe all of them,they're asking for your help in observing signs of climate change
across the world.The citizen scientist movement encourages ordinary people to observe a very specific

research interest一birds,trees,flowers budding,etc.and send their observations to a giant database to be
observed by professional scientists.This helps a small number of scientists track a large amount of data that they
would never be able to gather on their own.Much like citizen journalists helping large publications cover a
hyper-local beat,citizen scientists are ready for the conditions where they live in.All that's needed to become
one is a few minutes each day or each week to gather data and send them in.
A group of scientists and educators launched an organization last year called 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 alike to collect data about plant
flowering and leafing eveiy year.The program,called Project BudBurst,collects life cycle data on a variety of
common plants from across the United States.People participating in the project一which is open to every-
one一record their observations on the Project BudBurst website.
"People don't have to be plant experts一they just have to look around and see what's in their neighbor-
hood,"says Jennifer Schwartz,an education consultant with the project."As we collect these data,we'll be
able to make an estimate of how plants and communities of plants and animals will respond as the climate
changes."
What are citizen scientists asked to do? A:To develop a specific research interest and become professional scientists. B:To send their research observations to a professional database. C:To increase their knowledge about climate change. D:To keep a record of their research observations.
