We often take the Biosphere for granted and as the climate changes, plant species and ecosystems respond by adapting, migrating or reducing their population. Why is this important? The plants of the Biosphere feed us, clothe us, absorb carbon dioxide, provide us with oxygen,
Three-dimensional measurements of the central Brazilian Amazon rainforest have given NASA researchers a detailed window into the high number of branch falls and tree mortality that occur in response to drought conditions.
The colors on these maps show a measure of the "greenness" of Earth's landscapes. The values on these maps—ranging from -0.1 to 0.9—have no unit.
The eastern United States is well known for its widespread show of vibrant foliage each autumn. But western states grow more than just evergreen pines and palms; they also display some spectacular fall color.

In a May morning, a gray-haired woman counts the opened blooms on the bud clusters of a lilac branch that is just starting to release its sweet fragrance. She then goes into her house to access an Internet site, where she logs today as the "first bloom" date of her lilac plant.
This spring, the cherry trees around the Tidal Basin, southwest of the National Mall in Washington, D.C., are reaching peak bloom in early April 2018—timing that is in line with the 96-year average.
Drought conditions have affected much of the U.S. Southwest and Central Plains in recent years. But scientists now believe future droughts in the last half of this century could be the worst in the past millennium.
Identifying cause and effect relationships can help us make predictions about the function of natural systems and their impact on the world. These relationships, whether simple or complex, are vital for forecasting weather and predicting Earth events in new contexts.
