Norwich scientists help measure impact of climate change on Arctic plants

5 1 21

This year’s UN COP26 Conference will focus a lot on climate change and its impact on our world. Researchers from UEA’s School of Environmental Sciences at Norwich Research Park are involved in a project to measure how effective vegetation is in extracting carbon from our atmosphere.

Over the past few decades, the Arctic has been warming more than twice as fast as the rest of the planet. At the same time, long-term atmospheric carbon dioxide measurements have shown that the amount of carbon absorbed into and emitted by plants and soil - the terrestrial ecosystem – have increased substantially in the Arctic over many years.

Scientists had assumed this terrestrial ecosystem was playing a significant role in the changes they are seeing in the Arctic carbon cycle, but they lacked a technique to measure carbon uptake and release separately, which is key in understanding how the biosphere responds to climate change driven by fossil fuel emissions.

But a new study based on the modelling of atmospheric measurements of a related chemical - carbonyl sulfide - is providing insights into this important process in the Arctic boreal region, the area of the North American Arctic where vegetation grows.
