Quite a lot, actually! But to understand what the trees tell us, we first have to understand the difference between weather and climate. Weather is a specific (具体的) event—like a rainstorm or hot day—that happens over a short period of time. Weather can be tracked (追踪) within hours or days. Climate is the weather conditions in a place over a long time (30 years or more). Scientists at the National Weather Service have been keeping track of weather in the United States since 1891. But trees can keep a much longer record of Earth's climate. In fact, trees can live for hundreds, and sometimes even thousands of years. One way that scientists use trees to learn about climate is by studying a tree's rings. If you've ever seen a tree stump (树桩), you probably noticed that the top of the stump had some rings. These rings can tell us how old the tree is, and what the weather was like during each year of the tree's life. The light-colored rings represent (代表) wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring and one dark ring represents one year of the tree's life. Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past
