One of the largest carbon sinks on Earth is now being released rather than capturing cavity.2.
According to a new study by international teams, more than one -third of the Arctic Bonda (ABZ), including tundra, forests and wetlands around the Arctic Circle, pushes carbon instead of exiting the carbon. Massachusetts Woodwell Climate Research Center.
The same reversal occurs in some of the Amazon tropical rainforest.
ABZ is still considered to be carbon synches for thousands of years, but when the global temperature rises, some major areas are in danger and require detailed monitoring to understand how the place is going on.
“We have found that many northern ecosystems are still acting as carbon dioxide sinks, but the source area and fire now canceled many of the net absorption and reverse the long trend.” Say Woodwell Ecological Scholar Anna Virkkala.
The fire element is important. Researchers found that forest fires were more frequent and influenced by ABZ. According to statistics, 40 %of the ABZ is considering forest fires It gave more common2 Than absorption between 2001 and 2020Compared to 34 %if forest fires are not included.
This number is based on high resolution data and carefully edited in 200 carbon monitoring stations. ABC Flux Network, additional field measurement, weather information and computer modeling.
The result is changed according to the season. In summer, ABZ’s carbon sink is the most influential and more photosynthesis and photosynthesis with green plants. However, in winter, the abnormally warm temperature increases the amount of soil and organic matter exposed to the air, which means the larger release of CO.2 Than typical.
“Volatility is not amazing because the Arctic is not one place. It is a huge area with various ecosystems and climatic conditions.” Say Ecological scholar Sue natali from Woodwell climate.
“And now we have the ability to track and map the carbon process with spatial resolution, revealing what happens on the ground.”
During the study from 1990 to 2020, researchers found that ABZ was on average carbon sinks. It looks like a good news, but especially in the tundra area, the volatility hotspot is popular in different ways (as you can see in previous studies).
Almost half of the carbon stored in the soil on Earth In this area.
How the Earth’s change is changing, we need to know how to breathe all year round and how warmer and more green Arctic can contribute to the world’s air change.
“This very cooperative effort is important to understand how seasonal epidemiology and disturbance patterns can affect local and worldwide.” Say Texas University-Ecological Mauritz of the University of Texas-EL PASO.
This study has been published Natural climate change.
