The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis (光合作用) to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0. 8℃ since 1900, and nearly 0. 2 ℃ every ten years since 1979.
So far, efforts to cut emissions (排放) of planet- warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century—a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.
