Warmer temperatures and increased CO2 levels don’t stimulate tree growth

Warmer temperatures and higher levels of carbon dioxide associated with climate change were supposed to bode well for tree growth. But a recent study shows that this advantage isn’t seen in the trees of Canadian boreal forests. Researchers collected and analyzed tree-ring data and satellite images to determine how the changing temperatures and CO2 emissions […]

Keeping track of forests with satellite images

We can tell when deciduous trees’ photosynthesis cycles change, whether we’re aware of the phenomenon or not—we witness this every autumn, as the leaves change colour and fall off. 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 […]
