But in evergreen trees, the colour change is much subtler and therefore harder to track. An international team of researchers found that sensor data from satellites can be helpful in tracking photosynthesis cycles in entire forests of evergreens. This information is important in studies of climate change, since the frequency of photosynthesis cycles could point to the amount of carbon dioxide in the air absorbed by the trees.<\/span><\/strong><\/p>\n<p><strong>Authors:<\/strong><\/p>\n<p>John A.
