A study found that demolishing the accumulation of snow in the mountains of Northeast America will reduce the capacity of forests.
According to the study, in winter, now the common snapack and disastrous freeze-melting cycle is damaging the roots and the rate of nutrients and carbon uptake is decreasing. Action of National Science Academy,
The study authors led by Emeron Conrad-Rony of Boston University warned, “Current models abandon the complete complexity of winter climate change effects.”
In the Northeast, the temperate forests currently act about 20 percent of the greenhouse gas emissions of the region, the scientists said. But the combination of hot summer, snowopacks and many soil freeze-melting cycles have been transferred to the entire winter.
To understand whether there have been changes, researchers charts the development of red maple at Hubard Brooke Experimental Forest in New Hampshire since 2013-22.
In addition to establishing two reference plots, they arranged two plots, where the cable heated the soil from 5 ° C during the growing season and where there was four freeze-melody cycle during winter.
By 2022, scientists found that the tree biomass – an indicator of carbon uptake – warm plots increased by 63 percent, compared to no reference plots. They added this growth to an increase in nitrogen uttake during photosynthesis.
However, when plots were subjected to freeze-melting cycles in winter, their biomass increased only 31 percent-a potential result of root damage from melting and melting. That cycle, the authors explained, can damage the roots of the tree and reduce the absorption of their nutrients, while also obstructs carbon uptake during photosynthesis.
According to the study, the model of today’s Earth system is likely to keep in mind the negative effects of winter climate change and to focus on the positivity of warming on carbon storage, according to the study of today’s earth system, according to the study, according to the study, reduced the abilities of temperate forests to store carbon.
“Our findings highlight the significant relations between climate change in weather and northern temperate forest ecosystems processes and display significant requirements for the effects of climate change,” researchers concluded.
This accounting, they continue, during the seasons of both growing and winter, so that the ability of temperate forests to serve as a carbon sink can be gauged correctly.
Getting a better understanding of the issue, the researchers said, “will help improve the model and” will inform the policies for decarbonization and use nature-aid solutions for climate change. “
