In parts of the Arctic tundra, temperatures are increasing rapidly as a result of climate change. This has resulted in complex changes in plant communities, with satellite data showing that some parts of the Arctic are “greening” while other areas are said to be “browning.” Scientists are looking at components such as rock or soil types to understand changes in plant productivity in the Arctic, beyond just temperature. The image shows changes in mean maximum gross primary productivity across five years between 2001 and 2005 and 2011 and 2015.
