Rising CO2 limits nitrogen uptake in boreal forests, threatening carbon sink capacity | Chemistry World

Rising atmospheric carbon dioxide is limiting the amount of nitrogen boreal forests can make use of, an analysis of archived tree cores from Sweden has shown. This finding suggests that as humanity’s carbon dioxide emissions continue to rise trees will struggle to compete with microorganisms for nitrogen, slowing the growth of forests and reducing their importance as carbon sinks.

 

Larry’s Creek

Larry's Creek is what the Pennsylvania DOT terms a "High Crash Area" where the speed limit on the Susequehanna Beltway aka US 220 and future Interstate 99 become an at-grade highway, sometimes seperated by a concrete crash barrier but loads of driveways and businesses along the way. Eventually it will be upgraded to a superhighway, but that's some point off in the future.
