Article summary:
1. Over the last two decades, US forests have sequestered 700-800 million tons of CO2 per year.
2. It is unclear whether this increase in tree volume and C-sink has been driven by forest recovery from past land uses or other environmental factors such as elevated CO2.
3. This study uses data from tens of thousands of plots in the US to identify the role of elevated CO2 on wood volume in ten temperate forest groups.
Article analysis:
The article is generally reliable and trustworthy, as it provides a comprehensive overview of the research conducted on the effect of carbon fertilization on naturally regenerated and planted US forests. The article is well-structured and clearly explains the research design used to isolate the effects of elevated CO2 on wood volume in different forest groups. The article also provides evidence for its claims, such as citing experimental studies that have examined the role of elevated CO2, tree ring studies, and a meta-analysis of experimental results that estimated that each 100-ppm increase in CO2 increases aboveground volume in ecosystems by 8.2%.
However, there are some potential biases present in the article which should be noted. For example, while the article does mention other environmental factors such as N deposition or climate change that could influence forest stocks, it does not provide any evidence for these claims or explore them further. Additionally, while it mentions that forest management through planting and harvesting can play a role in Nationally Determined Contributions (NDCs), it does not provide any evidence for this claim either or explore how these approaches might affect NDCs. Finally, while it mentions that tree heights increased over time in Poland without identifying the role of CO2 concentration, it does not provide any evidence for this claim either or explore why this might be happening.
In conclusion, overall this article is reliable and trustworthy but there are some potential biases present which should be noted when considering its content.
