Landmark 20-year study of climate change impact on permafrost forests
In perhaps the first long-term study of CO2 fluxes in northern forests growing on permafrost, an Osaka Metropolitan University-led research team has found that climate change increased not only the sources of carbon, but also the CO2 sinks. The 20-year observation from 2003-2022 in the interior of Alaska showed that while CO2 sinks turned into sources during the first decade, the second decade showed a nearly 20% increase in CO2 sinks. Graduate School of Agriculture Associate Professor Masahito Ueyama and colleagues found that warming led to wetness, which in turn aided the growth of black spruce trees. During photosynthesis, the growing trees were using the increasing ...
